A pre-proposal Q&A webinar was held on April 25, 2023 at 1pm Eastern. Click here to watch the recording.

The Minority University Research and Education Project Partnership Annual Notification (MPLAN) connects Minority Serving Institutions (MSIs) with NASA Mission Directorates and promotes research collaboration. Funding up to $50,000 per award supports MSI teams to develop innovative ideas and action plans for commercialization. NASA provides expert guidance and resources throughout the program, enabling MSIs to unlock their full potential and deliver technological innovations that contribute to NASA's missions and benefit society.

This program consists of 2 phases:

  • In phase 1, MSI principal investigator’s (PI’s) submit proposals based on topics provided by NASA MUREP and the Mission Directorates:
    • Proposals should follow the submission and budget forms.
    • Phase 1 is open from April 11th, 2023 to May 30th, 2023.
  • In phase 2, awarded MSI PIs and their partners (if applicable) are invited to meet with NASA researchers and MUREP representatives. The meetings aim to serve as training sessions to pursue future NASA opportunities: 
    • The meetings/training primarily focus on fostering collaboration, enhancing technical skills, and providing insights into NASA's research priorities to better prepare participants for future opportunities.
    • Phase 2 occurs from July, 2023 until late 2023.
    • Only Phase 1 awardees are invited to participate in Phase 2. 
    • Phase 2 ends with a survey to better understand the experience and readiness of the MSI PI's to compete for future NASA opportunities. 

In Phase 2, NASA facilitates communication and meetings between awardees, Mission Directorate representatives, and subject matter experts. It is highly encouraged that awardees participate in these meetings to exchange information and receive the full benefits of this program. Awardees have the opportunity to participate in a kickoff meeting, engage monthly with NASA researchers, identify opportunities with NASA, and network with other PIs.


The Minority University Research and Education Project (MUREP) is administered through NASA's Office of STEM Engagement (OSTEM).The MUREP Partnership Annual Notification (MPLAN) seeks to reduce barriers faced by Minority Serving Institutions (MSIs) in engaging with NASA through a planning activity to prepare them for other NASA funding opportunities, including NASA’s annual Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) solicitation and NASA University Leadership Initiative. MPLAN is administered through MUREP, which provides competitive awards to MSIs, including Historically Black Colleges and Universities (HBCUs), Hispanic-Serving Institutions (HSIs), Asian American and Native American Pacific Islander Serving Institutions (AANAPISIs), Alaska Native-Serving and Native Hawaiian-Serving Institutions (ANNHs), American Indian Tribally-Controlled Colleges and Universities (TCUs), and Native American-Serving Nontribal Institutions (ASNTIs). See here for a full list of approved institutions.

MPLAN aims to initiate opportunities for long-term collaborations between MSI researchers and NASA by tackling some of the challenges and obstacles faced by the MSI research community. The overarching goal of MPLAN is to stimulate creative engagements for MSI researchers, leading to increased participation from MSIs in the development of new technologies that support NASA's mission and commercial market development. Ultimately, MPLAN seeks to establish viable partnerships that can compete in other NASA funding opportunities, such as the annual SBIR/STTR solicitation and NASA University Leadership Initiative, opening doors to new possibilities and growth.

Mission Directorate Topics

Mission Directorate Topics

MPLAN features topic areas from three NASA Mission Directorates. Select the Mission Directorate below to view their topics areas, or scroll to explore all three.

Space Technology Mission Directorate (STMD)

Technology drives exploration and the space economy. NASA’s Space Technology Mission Directorate (STMD) aims to transform future missions while ensuring American leadership in aerospace. As NASA embarks on the next era of space exploration with Artemis, STMD is advancing technologies and testing new capabilities at the Moon. Many of the same systems will prove critical at Mars. STMD’s portfolio spans a range of discipline areas and technology readiness levels.


STMD bolsters and funds diverse ideas from entrepreneurs, researchers, and innovators across the country. Space technology research and development occurs at NASA centers, universities, national labs, and small businesses. STMD leverages partnerships with other government agencies and commercial partners to quickly advance and demonstrate cross-cutting capabilities.


The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs within STMD provides opportunities for small, high technology companies and research institutions to participate in government-sponsored research and development (R&D) efforts in key technology areas. These highly competitive awards-based program enables small businesses to explore their technological potential and provide the incentive to profit from the commercialization of innovations. The STTR program specifically requires the small business to formally collaborate with a research institution. 

 

The focus area seeks to foster collaborations between Minority Serving Institutions (MSIs) and Small Business Concerns (SBCs) to enhance the opportunities provided through the STTR program. The goal is to develop mutually beneficial relationships that result in new technologies supporting the NASA mission and commercial market development. Grants are intended to address challenges and barriers faced by the MSI research community in developing collaborative opportunities. Funding enables universities and SBCs to engage in substantive conversations along mutual areas of interest, goals, and long-term outcomes. The desired result is to enable viable partnerships for competing in the annual STTR solicitation.

 

The STTR solicitation is comprised of multiple subtopics identified by the Agency as priority areas for research which could be satisfied by a small business with assistance from a research institution. Proposed research must indicate which STTR subtopic area the proposed research is aligned with to be considered responsive this announcement.

 

MSIs interested in submitting to an STMD topic area require a small business partner where the MSI is the lead in the application.

Below is a listing of the 2023 STTR Subtopics:

The subtopic "T6.08 Textiles for Extreme Surface Environments and High Oxygen Atmospheres" has been created to address the critical technology gap in textile technology to allow sustainable human exploration on the Moon. The intent of the 2023 solicitation is to focus on protection of humans and hardware outside of the lunar lander. This protection starts with the development of covers for practically everything that goes outside the lunar lander.

The most problematic challenge is the lunar regolith that is everywhere, levitates as soon as it is disturbed, and settles on anything around it since the Moon's gravity is only 1/6 of the Earth's gravity and there is no atmosphere. This means that the regolith is not weathered by winds and is very sharp. It also means that without oxygen, the regolith is not oxidized like everything is on Earth. Furthermore, the regolith of the lunar South Pole is different from that of the Mare region where the Apollo missions were conducted. The South Pole regolith is more abrasive. Like on Earth, different regions have different soils. The implication is that even with the best lunar dust simulants used in laboratories, we cannot exactly know the effect of the South Pole regolith of materials. Therefore, the need to have covers as impervious to the regolith as possible is of the utmost importance.

Hence, this subtopic has two scopes, one titled "Textiles for Extreme Lunar Environments and High Oxygen Atmospheres" that addresses requirements for the spacesuit, and another one that addresses the need for various types of hardware titled "Lunar Regolith Covers for Hardware."

Textiles for Extreme Lunar Environments and High Oxygen Atmospheres

Scope Description:

The environmental protection garment (EPG) is the outer component of the current spacesuit, which is called the Extravehicular Mobility Unit (xEMU). The xEMU is the new spacesuit developed for returning to the Moon. The EPG is a multilayered component consisting of fabrics and thin films. Each layer of this component contributes to the protection of the xEMU from the extreme lunar environment while enabling xEMU functionality of its three subsystems: the Pressure Garment System (PGS), the Portable Life Support System (PLSS), and the informatics system. The EPG is the spacesuit’s first line of defense. It must be designed to perform in the harsh surface environment of the South Pole of the Moon. It incorporates more advanced technologies than the current EMU (designed for use in low Earth orbit.) The xEMU is designed to be the next-generation spacesuit to benefit several space programs, namely the International Space Station, Human Landing System (HLS), Artemis, Gateway, and Orion.

The return of humans on the Moon means that everything outside the lunar lander or a habitat in future missions must be resilient to the lunar surface challenges. The most problematic challenge is the lunar regolith that is everywhere, levitates as soon as it is disturbed, and settles on anything around it. The Apollo spacesuits not only collected gray dust but also deteriorated from the damaging effects of the fine penetrating particles.

Lunar Environments

1. Thermal

The environment temperatures will be the temperature on the outside of the suit. The internal layers of the EPG are higher because of the suit heat leak provided by the astronaut, which warms the surrounding area.

 Extreme heat (260 °F, 127 °C)

 Extreme cold in permanently shadowed regions (-370 °F, -223 °C)

2. Regolith Terrain

The lunar regolith is a blanket of abrasive dust and unconsolidated, loose, heterogeneous, superficial deposits covering solid rock. The EPG fabrics must have sufficient resistance to abrasion and tear to last for multiple uses.

In the South Pole region of the Moon, the regolith is highly abrasive and prone to electrostatic and tribo-electrostatic charging. The electrostatic charges are produced by the photoemission of electrons due to vacuum ultraviolet (VUV) sunlight irradiation. The regolith becomes slightly positively charged. In the shadow, these charges reverse. In addition, the tribo-electrostatic charges are created by the friction of fabrics on the regolith.

3. Radiation and Plasma

The Moon does not have an atmosphere. Therefore, it receives unattenuated galactic and solar radiation. This solar radiation does not cause radioactivity. The annual Galactic Cosmic Rays dose in milli-Sieverts (mSv) on the Moon is 380 mSv (solar minimum) and 110 mSv (solar maximum). The annual cosmic ionizing cosmic radiation on Earth is 2.4 mSv. The EPG layers and particularly the outer layer fabric must be durable over hundreds of hours of VUV radiation exposure without a reduction in functionality.

Plasma is a concern due to the charged environment that may be in contact with the spacesuit. The plasma is explained in a PowerPoint document from Timothy J. Stubbs et al., “Characterizing the Near-Lunar Plasma Environment,” Workshop on Science Associated with the Lunar Exploration Architecture, Tempe, AZ, February 26 to March 2, 2007. https://www.lpi.usra.edu/meetings/LEA/whitepapers/Stubbs_charging_NAC_whitepaper_v01.pdf(link is external)

4. Architecture

The architecture of the xEMU EPG is based on a “hybrid-segmented” design in which inner layers of the EPG are segmented, with breaks around specific bearings, disconnects, and other components. The goal is to develop an EPG outer layer, which itself may be multilayered, to prevent dust intrusion and accommodate a range of sizes using overlapping sections. These sections are connected by reusable dust barrier zippers.

The EPG layers currently are:

Orthofabric of density 14.5 oz/yd2 for its mechanical properties of tensile and tear strengths, its optical properties that satisfy the thermal requirements, and to a lesser extent its abrasion resistance since the face of the fabric is made of Gore-Tex yarns.
Gore-Tex fabric of density 9.1 oz/yd2 per layer with a total of two layers to protect the adjacent thermal layers from solar radiation.
Aluminized Mylar® of density 1.12 oz/yd2 per layer with a total of seven layers for their heat transfer properties.
Neoprene-coated nylon with density 9.0 oz/yd2
Additional information on xEMU EPG architecture is given on this link: https://ttu-ir.tdl.org/handle/2346/89783(link is external)

Requirements

1.    Thermal

• Solar absorptivity to infrared emissivity of 0.21.
• Solar absorption is a value of 0.18 or less.

2.    Physical

 mass ≤42.57 oz/yd2 xEMU EPG mass

3.    Mechanical

  •   Have properties such that the microns and possibly some submicrons size regolith particles cannot penetrate the EPG.
  •   Be made of a single material or multilayered materials rather than laminated or composite materials more prone to delamination at cryogenic temperatures.
  •   Be more resistant to abrasion than Orthofabric to the sharp glassy regolith from the lunar South Pole.
  •   Be as or more flexible than the Orthofabric in extremely cold temperatures. 
  •   Survive 1,800 bending cycles at temperatures from -370 °F (-223 °C) to 260 °F (127 °C), and not snap from impact at the maximum cold temperatures.

4.    Oxygen-rich atmospheres

The EPG outer layer shall not support combustion in the lunar lander’s atmosphere of 34% ±2% oxygen at a pressure of 8.2 psia (56.5 kPa). This oxygen concentration may even be higher. Hence, all materials directly exposed to the lunar lander atmosphere are required to be flame retardant.

A spacesuit is essentially a one-person fully equipped spacecraft. It is complex and consists of more than 100 components. One of the primary purposes of the spacesuit is to protect the astronaut from the dangers in space outside the spacecraft. Therefore, it is more than just clothing.

Expected TRL or TRL Range at completion of the Project: 2 to 6  

Primary Technology Taxonomy:     

  • Level 1: TX 06 Human Health, Life Support, and Habitation Systems       
  • Level 2: TX 06.2 Extravehicular Activity Systems

Desired Deliverables of Phase I and Phase II:

  • Research
  • Analysis
  • Prototype

Desired Deliverables Description:

Phase I:  Phase I offerors are expected to deliver written reports (Interim and Final) containing a plan or strategy that explains in detail their approach for solving the problems of the EPG and the crew clothing. Reports shall include rationale for approach, research, proof of concept, analysis, and any strategy leading to one or more prototypes.

Phase II:  Phase II deliverables shall include prototypes or finished goods. The prototypes or finished goods shall be delivered to NASA Johnson Space Center with a “Material Inspection and Receiving Report” (Form DD250) OMB No. 0704-0248. Photographs of the delivered prototypes or finished goods shall accompany the DD250 form.  Deliverables shall also include complete documentation such as technical data sheets with a detailed description and composition of the material or product, with testing methods and testing data, design sketches or drawings, and full information on material and/or chemical sourcing. The Phase II deliverables shall also include a final report documenting all work accomplished for the Phase II effort and shall not duplicate the Phase II proposal.

Examples of the deliverables for the EPG and crew clothing may include:

  • EPG: prototype textiles with coating, lamination, thin film, other new technology, composite structure, or fabrics integrated in a spacesuit.
  • Crew clothing: novel fibers, yarns, and fabrics for everyday garment prototypes (e.g., T-shirt, pants, and sleepwear).

The proposers shall clearly state the Technology Readiness Levels (TRLs) at which they start their research and at which they expect to be at the end of Phase I and Phase II.  For the EPG, the TRL is expected to be the highest level possible at the end of Phase II. Reference for the TRL definitions are at the following link: https://www.nasa.gov/pdf/458490main_TRL_Definitions.pdf

State of the Art and Critical Gaps:

The gap is the lack of available commercial-off-the-shelf (COTS) textiles that satisfy spacesuit and crew clothing mitigation requirements for extreme surface environments and fire safety in a 36% oxygen atmosphere.

The second gap is the lack of knowledge of the effects of lunar dust on textile products with respect to their useful life in EVA applications.  Extent of wear and tear and levels of contamination and retention of the dust in the textile structure are not known.

The return of humans on the Moon means that everything outside the lunar lander or a habitat in future missions must be resilient to the lunar surface challenges.

Relevance / Science Traceability:

This scope is included under the Space Technology Mission Directorate (STMD). The xEMU project is under the Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate (SOMD). 

This work will benefit several space programs, namely the International Space Station, Human Landing System (HLS), Artemis, Gateway, and Orion.  Near term, the work on the EPG will directly benefit the xEMU project.

The textiles developed could be useful for other soft goods applications.

Lunar Regolith Covers for Hardware

Scope Description:

Human space exploration is always associated with a large amount of hardware that the astronauts need to perform their work. This implies that some of this hardware must also be resilient on the lunar surface. Hence, most of this hardware will also need protection from the lunar regolith. There will be many types of hardware. There will be simple tools, equipment deployed on the lunar surface like cameras, and machines like rovers. Each one will need a cover uniquely designed for its size, shape, and complexity. However, all of them will need covers to prevent contamination and damage from the lunar regolith. Depending on the type of hardware, the cover may not need to be as flexible and may be thicker. Some covers will have additional functions like thermal management of powered devices. The requirements of some covers may be exactly the same as those of the xEMU EPG and its outer layer. Other covers that do not have the mass and mechanical properties limitations as those imposed on the EPG may be developed quicker and serve as steps towards the development of the EPG outer layer. The two scopes will benefit from each other.

This scope invites the researchers to think about what they would develop to a cover for an articulated tool such that it does not lose its ability to be articulated, and then think about what they would do to cover a camera, etc., in the context of extreme temperatures as described in Scope 1.

It is envisioned that some of the first possible lunar infrastructures will be structures composed of bulk regolith and rocks. The intent of this subtopic is to develop lunar civil engineering designs, processes, and technologies that produce such structures, and develop concepts of operations (ConOps) for their construction in the South Polar region of the Moon. This is the lunar equivalent of terrestrial “Earth Works.” Earth-based civil engineering processes and technologies are not adequate for lunar construction, therefore lunar civil engineering technologies must be developed. Specific capabilities of interest are:

  • Establishing grade.
  • Rock removal.
  • Compaction.
  • Berm building.
  • Topography mapping to enable cut/fill operations planning and execution.
  • Geotechnical characterization.
  • Site preparation autonomous operations.
  • Regolith hauling/conveying for distances greater that 1 km.

The desired outcome of this effort is “Regolith Works” (engineered surface features and structures) and the design, prototype, testing, analysis, modeling, and demonstration of prototype equipment. These technologies are sought for scaled lunar construction demonstration missions. The following lunar civil engineered structures are of interest to NASA. Proposers are welcome to suggest other regolith-based infrastructure concepts.  

  • Bulk regolith-based launch/landing zones designed to minimize risks associated with landing/launching on unprepared surfaces for CLPS (Commercial Lunar Payload Services) and HLS (Human Landing System) vehicles.
  • Rocket Plume Surface Interaction (PSI) ejecta and blast protection structures.
  • Regolith base and subgrade for supporting hardened launch/landing pads, towers, habitats, and other in situ constructed structures.
  • Pathways for improved trafficability.
  • Solar Particle Event (SPE) and Galactic Cosmic Ray (GCR) shielding.
  • Structures for access to subgrade (e.g., trenches and pits).
  • Emplaced regolith overburden on structures and equipment.
  • Meteoroid impact protection structures.
  • Topographical features for terrain relative guidance for flight and surface vehicles.
  • Flat and level operational surfaces for equipment positioning, regularly accessed locations, and dust mitigation applications.
  • Sloped regolith ramps for access to challenging locations.
  • Utility corridors (e.g., electrical, comm, and fluids).
  • Shade structures.
  • Elevated operational surfaces.

Exact requirements for the full-scale bulk regolith structures are not yet known. Assumptions should be made with supporting rationale to enable initial designs. Specification of lunar civil engineering design criteria should be provided including geotechnical properties.

Tests and validated models/simulations should be developed to characterize the system and regolith infrastructure performance in its intended environments/applications. For example, effects of ejecta impingement upon proposed PSI ejecta protection structures should be characterized including phenomenon such as erosion or secondary ejecta trajectories. 

Development of PSI modeling capabilities is not in scope for this subtopic, but collaboration with ongoing PSI modeling efforts is welcome. Information on PSI characteristics can be obtained in the peer-reviewed literature and public NASA reports in the reference section.

ConOps should be developed to define the sequence of steps to complete construction tasks. The ConOps should begin with the natural lunar surface including hills, valleys, and surface and subsurface rocks, and end with the completed bulk regolith infrastructure verified to meet design criteria. A sequence of all required functions of robotic systems and implements should be defined to achieve the task. References to recommended existing spaceflight or protype hardware should be provided for each function. In cases where hardware does not exist, conceptual implement designs should be proposed and critical functions demonstrated in laboratory environments. Concepts should be appropriate for a CLPS scale demonstration mission on the lunar surface (e.g., 25 kg overall mass, 8 kg budget for implements) and assume that the implements would attach to an existing modular mobility platform with interfaces at the forward and aft position. Mobility platforms are not a focus for this topic. A depiction of the integrated construction system concept should be provided.

Proposers may select one or more systems/structures of interest to develop. Infrastructure designs that maximize risk reduction for the Artemis program will be prioritized.  ConOps that show promise for implementation by a single, compact, robotic construction system will rank high. Additionally, concepts that employ high Technology Readiness Level (TRL) implements will be prioritized. NASA is seeking systems that can build bulk regolith infrastructure that can be demonstrated in the near term. 

Research institute partnering is anticipated to provide analytical, research, and engineering support to the proposers. Examples may include applying civil engineering principles and planning methods, identification and development of needed standards or specifications for lunar structures and operations, regolith interaction modeling, development of analytical models and simulations for verification of system performance, and methods for the design and prototyping of hardware and associated software.

Expected TRL or TRL Range at completion of the Project: 2 to 5

Primary Technology Taxonomy:

  • Level 1: TX 07 Exploration Destination Systems
  • Level 2: TX 07.2 Mission Infrastructure, Sustainability, and Supportability

Desired Deliverables of Phase I and Phase II:

  • Research
  • Analysis
  • Prototype
  • Hardware
  • Software

Desired Deliverables Description:

Phase I must include the design and test of critical attributes associated with the proposed site preparation technology, operations, and achieved site characteristics. Civil engineered design of bulk regolith infrastructure including associated testing, modeling, and simulations must be included. Phase I must also include a ConOps for constructing the infrastructure and verifying the as-built characteristics meet design criteria. An overall construction system concept must be provided. Phase I proposals should result in at least TRL 4 structures and implements.

Phase II deliverables must include demonstration of construction and characterization of bulk regolith infrastructure. The infrastructure must be constructed using robotic systems and implements. Proof of critical functions of the infrastructure and systems must be demonstrated. Structures and systems must be developed to a minimum of TRL 5. Phase II must also include updates to the bulk regolith infrastructure designs, tests, modeling, and simulation based on Artemis program needs refinement and new information.

State of the Art and Critical Gaps:

While civil engineering and construction are well-established practices on Earth, lunar applications remain at low TRLs. The design requirements and functional capabilities of bulk regolith-based lunar infrastructure are not well defined. To date, very few studies have performed civil engineering designs of bulk regolith infrastructure for lunar surface applications. Tests have been performed on Earth but only for short periods of time and with limited environmental and operational fidelity.

Relevance / Science Traceability:

Construction of bulk regolith infrastructure directly addresses the Space Technology Mission Directorate (STMD) strategic thrust “Land: Increase Access to Planetary Surfaces.” It also addresses the strategic thrust of “Live: Sustainable Living and Working Farther from Earth” 

Sustainable Atmospheric Carbon Dioxide Extraction and Transformation

Scope Description:

Component and subsystem technologies are sought to demonstrate sustainable, energy-efficient extraction of carbon dioxide (CO2) from a defined planetary or habitable atmosphere fully integrated with CO2 transformation into one or more stable products such as manufacturing feedstock polymers or readily storable, noncryogenic propellants or fuels. This scope is intended to incentivize revolutionary, dual-use technologies that may lead to reduced dependence of sustainable space exploration activity on terrestrial supplies of carbon-containing resources and also lead to products with commercial promise for repurposing terrestrial atmospheric CO2. At the core of this scope is a requirement for integrated technology solutions that dramatically reduce mass, volume, and end-to-end energy consumption of highly integrated CO2 collection and transformation.

Proposals must specifically and clearly describe: (1) physical and/or chemical processes to be implemented for CO2 collection and transformation, including reference to the current state of the art; (2) specific engineering approaches to be used in dramatically reducing mass, volume, and end-to-end energy consumption per mass of product carbon content mass; (3) validated performance estimates of high-cycle utilization of any sorption, catalytic, or other unconsumed materials used in the CO2 collection or transformation processes; (4) suitability or adaptability of the proposed CO2 capture approach for operation in various ambient CO2 mixture and partial pressure environments (i.e., ambient Mars atmosphere to ambient Earth atmosphere conditions); (5) substantiated estimates of the mass conversion efficiency of ingested carbon to product carbon; and (6) estimated total end-to-end energy consumption per unit mass of product carbon.

The scope specifically excludes: (1) evolutionary improvements in mature CO2 collection technologies that do not provide large reductions in mass, volume, and end-to-end energy consumption; (2) CO2 collection approaches that employ CO2 absorbing materials that require frequent replenishment or replacement (e.g., greater than 50% reduction in absorption efficiency after 500 cycles); (3) technologies considered as life support systems including air revitalization, water processing, or waste processing; (4) biological or biology-based components or subsystems of any kind; and (5) CO2 transformation products that are not readily stored at approximately Earth-ambient conditions such as cryogenic propellants.

Desired Deliverables Description:

Phase I deliverable is defined as a detailed feasibility study that clearly defines the specific technical innovation and estimated performance of CO2 collection and transformation into products, identifying critical development risks anticipated in a Phase II effort. Technology feasibility evaluation should address the scope proposal elements including: (1) process descriptions; (2) results of engineered mass, volume, and energy consumption efficiency designs; (3) cyclic performance of participating unconsumed process materials; (4) adaptability to different atmospheric CO2 mixtures and partial pressures; (5) ingested atmosphere throughput and carbon conversion efficiency to product carbon, and (6) estimated total end-to-end energy consumption per unit mass of product carbon. Phase I feasibility deliverables should include laboratory test results that demonstrate the performance of unit processes, components, or subsystems against these metrics.

State of the Art and Critical Gaps:

This topic is intended to solicit innovative technologies with clear dual use: (1) adoption by NASA for infusion into long-term mission capabilities enabling mission scale in-situ resource utilization (ISRU) use of the martian atmosphere and (2) commercialization and the potential formation of a terrestrial industry to meet potentially significant future demand for terrestrial atmospheric CO2 extraction and repurposing. Additionally, if or as a viable industry associated with terrestrial applications of these technologies emerges, commercial competition may continue to drive innovation and contribute over the long term to improved NASA mission capability. Early-stage innovations in this topic are anticipated from teams of small businesses and research institutions, which can demonstrate feasibility and readiness for accelerated maturation.

Well-developed and mature technologies for atmospheric CO2 capture have been flown and operated on NASA spacecraft, based on phase change (freezing) of ambient gas; accepting the power requirements and efficiency levels of both the refrigeration and heating devices in a freeze/thaw-based collection cycle. The NASA operational collection of CO2 from habitable atmospheres is performed using flow-through beds of sorption materials driven to saturation followed by either desorption processes or discarding of the sorption material and the collected CO2. Similarly, CO2 processing based on electrochemical reduction of CO2 into carbon monoxide (CO) has been flown demonstrating production of oxygen from atmospheric sources. However, the collected carbon is a disposable byproduct. Significantly, these systems are not developed nor optimized for recovery and repurposing of considerable process heat drawn from spacecraft power sources, nor for repurposing of the collected carbon. Recent literature suggests emerging laboratory research of both efficient CO2 capture and repurposing processes is occurring and may be well positioned for development into components and subsystems suitable for longer-term infusion by NASA into ISRU systems and an emerging terrestrial industry.

Relevance / Science Traceability:

The quantification of resources on Mars suitable for the local production of a variety of mission consumables, manufactured products, and other mission support materials has become much better understood through recent in situ measurements and introductory technology demonstrations. Evolving mission scenarios for expanded robotic and human exploration of Mars uniformly depend on the utilization of these resources to dramatically reduce the cost and risks associated with these exploration goals. In order to reduce the broad goal of utilizing the CO2 of the martian atmosphere as a source of both carbon and oxygen to practical, full-scale reality, substantial improvements in system mass, volume, and power requirements are needed. This solicitation is intended to incentivize these innovations in the service of future NASA missions.

Additionally, there is a growing recognition of the planetwide consequences of accumulating CO2 in the terrestrial atmosphere. Technologies that advance NASA's Mars ISRU aspirations may be created with the necessary energy efficiencies to support scaling up to terrestrial industrial capacity large enough to begin to reduce or reverse atmospheric CO2 accumulation. 

Sustainable Production of Hydrogen for Transportation and Energy Storage Applications

Scope Description:

This scope is therefore intended to strongly emphasize significant overall efficiencies in size, weight, and energy consumption and utilization. The scope specifically excludes incremental improvements in existing water electrolysis technologies.

State of the Art and Critical Gaps:

This topic is intended to solicit innovative technologies with clear dual use: (1) adoption by NASA for infusion into long-term mission capabilities enabling quasi-industrial scale ISRU and energy storage use of indigenous water resources and (2) commercialization and the potential formation of a terrestrial industry to meet potentially significant future demand for hydrogen for energy storage, advanced aviation and surface transportation fuels, and feedstock for manufactured products. Additionally, if or as a viable industry associated with terrestrial applications of these technologies emerge, a commercial competition may continue to innovate and contribute over the longer term to improved NASA mission capability. Early-stage innovations in this topic are anticipated from teams of small businesses and research institutions, which can demonstrate feasibility and readiness for accelerated maturation.

Relevance / Science Traceability:

The application of compact, energy-efficient hydrogen production technologies will occur in future power and energy storage and ISRU implementations on the Moon and on Mars, which are currently constrained by the use of conventional water electrolysis approaches. Technologies that successfully address size, mass, and energy consumption constraints for spaceflight applications will enable the utilization of those efficiencies as the basis for scaling up to commercial production for terrestrial applications at far larger production volumes than needed for spaceflight applications. This solicitation is intended to incentivize these innovations in the service of future NASA missions.

Quantum Sensing and Measurement calls for proposals using quantum systems to achieve unprecedented measurement sensitivity and performance, including quantum-enhanced methodologies that outperform their classical counterparts. Shepherded by advancements in our ability to detect and manipulate single quantum objects, the so-called Second Quantum Revolution is upon us. The emerging quantum sensing technologies promise unrivaled sensitivities and are potentially game changing in precision measurement fields. Significant gains include technology important for a range of NASA missions such as efficient photon detection, optical clocks, gravitational wave sensing, ranging, and interferometry. Proposals focused on atomic quantum sensors and clocks, and quantum communication should apply to those specific subtopics and are not covered in this Quantum Sensing and Measurement subtopic.

Quantum Communications seeks proposals that develop technologies to support quantum communications between satellites and ground stations. Key aspects of these components are high performance, the ability to support free-space quantum communication between moving nodes, as well as low size, weight, and power (SWaP). 

Quantum Sensing and Measurement

Scope Description:

Specifically identified applications of interest include quantum sensing methodologies achieving the optimal collection light for photon-starved astronomical observations, quantum-enhanced ground-penetrating radar, and quantum-enhanced telescope interferometry.

  • Superconducting Quantum Interference Device (SQUID) systems for enhanced multiplexing factor reading out of arrays of cryogenic energy-resolving single-photon detectors, including the supporting resonator circuits, amplifiers, and room temperature readout electronics.
  • Quantum light sources capable of efficiently and reliably producing prescribed quantum states including entangled photons, squeezed states, photon number states, and broadband correlated light pulses. Such entangled sources are sought for the visible infrared (vis-IR) and in the microwave entangled photons sources for quantum ranging and ground-penetrating radar.
  • On-demand single-photon sources with narrow spectral linewidth are needed for system calibration of single-photon counting detectors and energy-resolving single-photon detector arrays in the midwave infrared (MIR), near infrared (NIR), and visible. Such sources are sought for operation at cryogenic temperatures for calibration on the ground and aboard space instruments. This includes low SWaP quantum radiometry systems capable of calibrating detectors' spectroscopic resolution and efficiency over the MIR, NIR, and/or visible.

Quantum Sensing and Measurement includes: Quantum Metrology and Radiometry (absolute radiometry without massive blackbody cryogenic radiometer or synchrotron), Quantum Sources (prepare prescribed quantum states with high fidelity), Quantum Memories (storage and release of quantum states), Quantum Absorbers and Quantum Amplifiers (efficiently absorption and detection of quantum states).

Desired Deliverables Description:

NASA is seeking innovative ideas and creative concepts for science sensor technologies using quantum sensing techniques. The proposals should include results from designs and models, proof-of-concept demonstrations, and prototypes showing the performance of the novel quantum sensor.

Phase II should include prototype delivery to the government. (It is understood that this is a research effort, and the prototype is a best effort delivery where there is no penalty for missing performance goals.) The Phase II effort should be targeting a commercial product that could be sold to the government and/or industry.

State of the Art and Critical Gaps:

Quantum Entangled Photon Sources:

Sources for generation of quantum photon number states. Such sources would utilize high detection efficiency photon energy-resolving single-photon detectors (where the energy resolution is used to detect the photon number) developed at NASA for detection. Sources that fall in the wavelength range from 20 μm to 200 nm are of high interest. Photon number state generation anywhere within this spectral range is also highly desired including emerging photon-number quantum state methods providing advantages over existing techniques. (Stobińska, et al., Sci. Adv. 5 (2019)). Also interested in proposal generating Holland-Burnett states (Phy Rev. Let 71, 1355 (1993)).

Quantum dot source produced entangled photons with a fidelity of 0.90, a pair generation rate of 0.59, a pair extraction efficiency of 0.62, and a photon indistinguishability of 0.90, simultaneously (881 nm light) at 10 MHz. (Wang, Phys. Rev. Lett. 122, 113602 (2019)). Further advances are sought.

Spectral brightness of 0.41 MHz/mW/nm for multimode and 0.025 MHz/mW/nm for single-mode coupling. (Jabir: Scientific Reports. 7, 12613 (2017)).

Higher brightness and multiple entanglement and heralded multiphoton entanglement and boson sampling sources. Sources that produce photon number states or Fock states are also sought for various applications including energy-resolving single-photon detector applications.

For energy-resolving single-photon detectors, current state-of-the-art multiplexing can achieve kilopixel detector arrays, which with advances in microwave SQUID, multiplexing can be increased to megapixel arrays. (Morgan, Physics Today. 71, 8, 28 (2018)).

Energy-resolving detectors achieving 99% detection efficiency have been demonstrated in the NIR. Even higher quantum efficiency absorber structures are sought (either over narrow bands or broadband) compatible with transition-edge sensor (TES) detectors. Such ultra-high- (near-unity-) efficiency absorbing structures are sought in the ultraviolet, vis-IR, NIR, mid-infrared, far infrared, and microwave.

Quantum memories with long coherence times >30 ms to several hours and efficiency coupling. Want to show a realistic development path capable of highly efficient coupling to photon number resolving detectors. 

Absolute detection efficiency measurements (without reference to calibration standards) using quantum light sources have achieved detection efficiency relative uncertainties of 0.1% level. Further reduction in detection efficiency uncertainty is sought to characterize ultra-high-efficiency absorber structures. Combining calibration method with the ability to tune over a range of different wavelengths is sought to characterize cryogenic single-photon detector's energy resolution and detection efficiency across the detection band of interest. For such applications, the natural linewidth of the source lines must be much less than the detector resolution (for NIR and higher photon energies, resolving powers R = E/ΔEFWHM = λ/ΔλFWHM much greater than 100 are required). Quantum sources operating at cryogenic temperatures are most suitable for cryogenic detector characterization and photon number resolving detection for wavelengths of order 1.6 μm and longer.

For quantum sensing applications that would involve a squeezed light source on an aerospace platform, investigation of low SWaP sources of squeezed light would be beneficial. From the literature, larger footprint sources of squeezed light have demonstrated 15 dB of squeezing (Vahlbruch, et al., Phys. Rev. Lett. 117, 11, 110801 (2016)). For a source smaller in footprint, there has been a recent demonstration of parametric downconversion in an optical parametric oscillator (OPO) resulting in 9.3 dB of squeezing (Arnbak, et al., Optics Express. 27, 26, 37877-37885 (2019)). Further improvement of the state-of-the-art light squeezing capability (i.e., >10 dB), while maintaining low SWaP parameters, is desired.

Quantum Communications

Scope Description:

NASA seeks to develop quantum networks to support the transmission of quantum information for aerospace applications. This distribution of quantum information could potentially be utilized in secure communication, sensor arrays, and quantum computer networks. Quantum communications may provide new ways to improve sensing the entangling of distributed sensor networks to provide extreme sensitivity for applications such as astrophysics, planetary science, and Earth science. Technologies of interest are components to support the communication of quantum information between quantum computers, or sensors, for space applications or supporting linkages between free space and terrestrial fiber-optic quantum networks.

Deliverables that substantiate technology efficacy include reports of key experimental demonstrations that show significant capabilities, but in general, it is desired that the deliverable include some hardware that shows the demonstrated capability.

State of the Art and Critical Gaps:

Quantum communications is called for in the 2018 National Quantum Initiative (NQI) Act, which directs the National Institute of Standards and Technology (NIST), National Science Foundation (NSF), and the Department of Energy (DOE) to pursue research, development, and education activities related to Quantum Information Science.

In terms of quantum sensing arrays, there are a number of sensing applications that could be supported through the use of quantum sensing arrays for dramatically improved sensitivity.

T8.07 Photonic Integrated Circuits

Scope Description:

Photonic integrated circuits (PICs) are a revolutionary technology that enable complex optical functionality in a simple, robust, reliable, chip-sized package with very low size, weight, and power (SWaP), extremely high performance, and low cost. PICs are the optical analog to electrical integrated circuits (EICs). In the same way that EICs replaced vacuum tubes and other bulk electrical components, PICs are revolutionizing the generation and manipulation of light (photons), replacing free-space optics and parts with chip-based optical waveguides and components. This technology has been pioneered in the telecommunications industry but much of the functionality and components are also directly applicable to science measurements and spacecraft technologies.

NASA is interested in the development and maturation of photonic integrated circuit (PIC) technology for infusion into existing and upcoming instruments. For the purposes of this call, PIC technology is defined as one or more lithographically defined photonic components or devices (e.g., lasers, detectors, waveguides/passive structures, modulators, electronic control, and optical interconnects) on a single platform allowing for manipulation and confinement of light at or near the wavelength scale. PICs can enable size, weight, and power (SWaP) and cost reductions and improve the performance of science instruments, subsystems, and components. PIC technologies are particularly critical for enabling small spacecraft platforms, rovers, and wearable/handheld technology for astronauts. Proposals should clearly demonstrate how the proposed PIC component or subsystem will demonstrate improved performance: reduced SWaP and cost; increased robustness to launch, space, and entry/landing environments; and/or entirely new measurement functionalities when compared to existing state-of-the-art bulk fiber-optic technology. 

Additional clarifications:

  • On-chip generation, manipulation, and detection of light in a single-material system may not be practical or offer the best performance, so hybrid packaging of different material systems are also of interest.
  • Often the full benefits of photonic integration are only realized when combined with integrated electronics. Proposals that leverage co-integrated electronics for new/improved PIC functionality are invited, but should consider the ultimate space environment.
  • There are advantages to development of PIC technology in existing open access foundries to enable low cost, continued support, commercialization, and cross-compatibility with other development efforts.

General NASA areas of interest for PIC components and subsystems include, but are not limited to:

  • 3D mapping and spectroscopic lidar systems and components.
  • Sensors for rovers, landers, and probes.
  • PIC-based analog radio-frequency (RF), microwave, submillimeter, and terahertz signal processing.

Several existing needs at NASA for PIC technology include:

  • PICs suitable for terahertz spectroscopy, microwave radiometry, and hyperspectral microwave sounding needing integrated high-speed electro-optic modulators, optical filters with tens of GHz free-spectral-range and few GHz resolution. Ka-band operation of RF photonic up/down frequency converters and filters need wideband tunability (>10 GHz) and <1 GHz instantaneous bandwidth.
  • Spectrometers:
  • Spectrometers or enabling spectrally resolving components with sufficient resolution to resolve atomic isotopes (e.g., carbon, oxygen, and hydrogen), with some examples including at least 0.02 cm-1 resolution at 2,196 cm-1 (>100k resolving power) and at least 0.02 cm-1 resolution at 1,294 cm-1 (>50k resolving power).
  • Miniature spectrometers with high resolution (resolving power >10k) and high dynamic range (>4 orders of magnitude) in the 1.6 to 2.0 µm band for fire detection.
  • Spectrometers or spectrally resolving components capable of highly multimode (10+) and/or imaging operation on a single chip.
  • On-chip detectors with high responsivity/quantum efficiency from 300 to 800 nm and >1.6 µm. Note that approaches which package on-chip waveguides to off-chip detectors using small-form-factor packaging techniques (direct edge coupling, flip-chip, photonic wirebonding, etc.) are also of interest. Additionally, approaches demonstrated in, or compatible with, commercial foundries are of particular interest.
    • Avalanche photodiodes or similar single photon sensitive detectors in any wavelength range.
  • Packaging approaches and on-chip coupling components for high-density, high-bandwidth, and/or misalignment-tolerant connections to single mode and multimode optical fiber, in any wavelength range. Note that photonic lanterns, mode size converters, 3D-written waveguide arrays, fiber arrays, and other “off-chip” coupling components must be packaged with a PIC to be considered responsive. In this case, the PIC should allow for measurement of total insertion loss but need not have any additional functionality. Note that proposals demonstrating a new coupler design will preferably focus on coupler design in a commercial foundry process. Designs and methods for coupling a single mode waveguide to a large-area beam (>1 mm diameter) emitted with high efficiency (<6 dB insertion loss) directly from the chip surface without an external lens. Both beam-steering and static approaches are invited. Example approaches include optical phased arrays, large-area grating couplers, and metalens-based structures. Note that approaches utilizing an on-chip fabricated lens (i.e., deposited on the chip surface) are also invited.

State of the Art and Critical Gaps:

There is a critical gap between discrete and bulk photonic components and waveguide multifunction PICs. The development of PICs permits SWaP and cost reductions for spacecraft microprocessors, communication buses, processor buses, advanced data processing, and integrated science instrument optical systems, subsystems, and components. This is particularly critical for small spacecraft platforms.

The United States is entering an unprecedented era for hypersonic and space vehicle development. The Department of Defense (DoD) is currently pursuing multiple hypersonic weapon development programs to advance boost-glide and air-breathing vehicle concepts and has conducted successful flight tests of both vehicle types in recent years. Total DoD investment in hypersonic research is expected to approach $5B in fiscal year 2023. NASA is preparing to return humans to the Moon for the first time in 50 years, while simultaneously developing a portfolio of ambitious planetary science missions that include returning rock samples from Mars and landing a mobile science platform on Titan. The commercial space sector is booming, with dozens of companies pursuing economic objectives in low Earth orbit that are independent of the US Government. In 2021, private investment in space startups exceeded $15B, up from roughly $2.5B just five years prior.

Connecting all these efforts is the need for robust, fast, and accurate simulation of novel flight vehicles as they traverse atmospheres at supersonic and hypersonic speeds. Heat transfer and high temperature gas physics become critical design drivers in this regime. Strong shocks and shear layers stress existing simulation technologies. Increasingly complex vehicles defeat the techniques and best practices presently used to conduct analysis in this regime. The U.S. commercial space industry, defense industry, and NASA require advanced simulation tools and technologies that make the design of new hypersonic flight vehicles faster and more economical.

This subtopic seeks to stimulate advances in aeroscience simulation software that will directly address this pressing national need. Specifically, this solicitation seeks mature innovative research into practical simulation solutions that enable: (1) efficient exploitation of exascale computing platforms; (2) highly automated aerothermodynamic analysis of complex vehicles in strongly shocked flows; and (3) economical simulation of unsteady, supersonic fluid phenomena.

Aerothermal Simulation for Exascale Computer Architectures

Scope Description:

Aerothermodynamic simulations of planetary entry vehicles such as Orion and Dragonfly are complex and time consuming. These simulations, which solve the multispecies, multitemperature Navier-Stokes equations, require detailed models of the chemical and thermal nonequilibrium processes that take place in high-temperature shock layers. Numerical solution of these models results in a large system of highly nonlinear equations that are exceptionally stiff and difficult to solve efficiently. As a result, aerothermal simulations routinely consume 20 to 50 times the compute resources required by more conventional supersonic computational fluid dynamics (CFD) analysis, limiting the number of simulations delivered in a typical engineering design cycle to only a few dozen. Moreover, entry system designs are rapidly increasing in complexity, and unsteady flow phenomena such as supersonic retropropulsion are becoming critical considerations in their design. This increases the compute resources required for aerothermal simulation by an additional one to two orders of magnitude, which precludes the delivery of such simulations in engineering-relevant timescales.

To deliver the aerothermal simulations required for NASA’s next generation of entry systems, access to greatly expanded compute resources is required. However, scaling conventional central processing unit (CPU) based supercomputers is problematic due to cost and power constraints. Many-core accelerators, such as the general-purpose graphical processing units (GPGPUs) developed by NVIDIA and AMD, offer increased compute capability with reduced cost and power requirements and are seeing rapid adoption in top-end supercomputers. As of June 2022, 168 of the top 500 fastest supercomputers leveraged accelerators or co-processors, including 7 of the top 10 [1]. The first U.S. supercomputer to break the exascale barrier, Frontier at Oak Ridge National Laboratory, utilizes AMD Instinct GPGPUs to achieve 1.1 exaflops of sustained LINPACK performance, and the other two exascale supercomputers planned by the U.S. Department of Energy will also utilize GPGPUs [2]. NASA deployed a first tranche of NVIDIA V100 GPGPUs as part of the High-End Compute Capability (HECC) project in 2019 [3].

Critically, NASA’s principal aerothermal simulation tools are fundamentally unable to run on many-core accelerators and must be reengineered from the ground up to efficiently exploit such devices. This scope seeks to revolutionize NASA’s aerothermal analysis capability by developing novel simulation tools capable of efficiently targeting the advanced computational accelerators that are rapidly becoming standard in the world’s fastest supercomputers, while simultaneously enabling the tools to run efficiently on conventional CPU architectures with as much code re-use as possible. A successful solution within this scope would demonstrate efficient simulation of a large-scale aerothermal problem of relevance on an advanced many-core architecture, e.g., the NVIDIA Ampere GPGPU, and conventional CPUs using a prototype software package.

Desired Deliverables Description:

The desired deliverable at the conclusion of Phase I is a prototype software package capable of solving the multispecies, multitemperature, reacting Euler equations on an advanced many-core accelerator such as an NVIDIA A100 GPGPU. Parallelization across multiple accelerators and across nodes is not required. The solver shall demonstrate offloading of all primary compute kernels to the accelerator, but may do so in a nonoptimal fashion, e.g., using managed memory, serializing communication and computation, etc. Some noncritical kernels such as boundary condition evaluation may still be performed on a CPU. The solver shall demonstrate kernel speedups (excluding memory transfer time) when comparing a single accelerator to a modern CPU-based, dual-socket compute node. However, overall application speedup is not expected at this stage. The solver shall be demonstrated for a relevant planetary entry vehicle such as FIRE-II, Apollo, Orion, or the Mars Science Laboratory.

A successful Phase II deliverable will mature the Phase I prototype into a product ready for mission use and commercialization. Kernels for evaluating viscous fluxes shall be added, enabling computation of laminar convective heat transfer to the vehicle. Parallelization across multiple accelerators and multiple compute nodes shall be added. Good weak scaling shall be demonstrated for large 3D simulations (>10M grid cells). The implementation shall be sufficiently optimized to achieve an ~5-time reduction in time-to-solution compared to NASA's Data-Parallel Line Relaxation (DPLR) aerothermal simulation code, assuming each dual-socket compute node is replaced by a single accelerator (i.e., delivered software running on eight GPGPUs shall be 5 times faster than DPLR running on eight modern, dual-socket compute nodes). Finally, the accuracy of the delivered software shall be verified by comparing to the DPLR and/or LAURA codes. The verification study shall consider flight conditions from at least two of the following planetary destinations: Earth, Mars, Titan, Venus, and Uranus/Neptune.

State of the Art and Critical Gaps:

NASA’s existing aerothermal analysis codes (LAURA, DPLR, US3D, etc.) all utilize domain-decomposition strategies to implement coarse-grained, distributed-memory parallelization across hundreds or thousands of conventional CPU cores. These codes are fundamentally unable to efficiently exploit many-core accelerators, which require the use of fine-grained, shared-memory parallelism over hundreds of thousands of compute elements. Addressing this gap requires reengineering our tools from the ground up and developing new algorithms that expose more parallelism and scale well to small grain sizes.

Many-core accelerated CFD solvers exist in academia, industry, and government. Notable examples are PyFR from Imperial College London [4], the Ansys Fluent commercial solver [5], and NASA Langley’s FUN3D code [6]. However, most of the work to date has focused on perfect gas flow models, which have different algorithmic and resource requirements compared to real gas models. The two notable exceptions are the Sandia Parallel Aerodynamics and Reentry Code (SPARC) [7] and FUN3D’s FLUDA library for GPU-accelerated real-gas simulation [8,9], both of which have demonstrated multispecies, multitemperature simulations at scale using GPGPU technology. However, broader infusion of advanced architecture capability into the hypersonic/EDL (entry, descent, and landing) simulation community is still required, as is the development of advanced nonlinear solver technologies that perform well on many-core architectures.

Relevance / Science Traceability:

This scope is directly relevant to NASA space missions in both Exploration Systems Development Mission Directorate and Space Operations Mission Directorate (ESDMD-SOMD) with an EDL segment. These missions depend on aerothermal CFD to define critical flight environments and would derive large, recurring benefits from a more responsive and scalable simulation capability. This scope also has potential crosscutting benefits for tools used by Aeronautics Research Mission Directorate (ARMD) to simulate airbreathing hypersonic vehicles. Furthermore, this scope directly supports NASA’s CFD Vision 2030 Study, which calls for sustained investment to ensure that NASA’s computational aeroscience capabilities can effectively utilize the massively parallel, heterogeneous (i.e., GPU-accelerated) supercomputers expected to be the norm in 2030.

Robust and Automated Aerothermal Simulation of Complex Geometries

Scope Description:

NASA’s production aerothermodynamic flow solvers all share a common characteristic: they utilize conventional second-order accurate finite volume schemes to spatially discretize the governing flow equations. Schemes of this type are ubiquitous in modern compressible CFD solvers. They are reasonably simple to implement and optimize on conventional CPU-based computer architectures and can provide engineering accuracy for a wide range of problems. Unfortunately, one area where these schemes struggle to deliver acceptable accuracy is at hypersonic speeds when a strong shock wave forms ahead of the vehicle. In such cases, the computed surface heat flux exhibits extreme sensitivity to the design of the computational grid near the shock [1], which must be constructed from cell faces that are either parallel or perpendicular to the shock to minimize error.

This stringent requirement for shock-aligned grids effectively precludes the use of unstructured tetrahedral meshes in aerothermal simulation. Current engineering practice employs a limited form of mesh adaption, commonly referred to as "shock tailoring," whereby cell faces in a block-structured grid are aligned and clustered near the shock [2]. While effective, this approach is extremely limiting and makes it technically difficult and extremely time consuming to generate computational grids for nontrivial vehicle geometries. More general shock tailoring techniques exist based on hybrid prismatic-tetrahedral unstructured grids [3], but current implementations are limited to fitting just the bow shock, do not guarantee accuracy or efficiency of the resulting grid/solution, and can present numerical challenges for some flow solvers due to rapid changes in cell volume at topological boundaries.

Fortunately, recent research has demonstrated several promising avenues to address the strong shock capturing problem. One such avenue is the use of advanced numerical schemes such as the Discontinuous Galerkin (DG) method, which has been shown to deliver high-quality solutions for shock-dominated flows on fully unstructured grids when appropriate stabilization mechanisms are employed [4,5]. Alternatively, advanced algorithms for metric-aligned unstructured grid generation [6,7], combined with techniques for recovering locally structured grids from metric-aligned tetrahedral grids [8], may provide a path forward for accurately capturing strong shocks, either on their own or in combination with advanced numerical schemes.

This scope seeks to revolutionize NASA’s aerothermal analysis capability by enabling rapid, robust, and highly automated analysis of complex hypervelocity flight systems. A successful solution within this scope would demonstrate accurate computation of surface heat flux on a complex entry vehicle, e.g., the Space Shuttle, at multiple flight conditions relevant to planetary entry with little-to-no user interaction.

Primary Technology Taxonomy:

  • Level 1: TX 09 Entry, Descent, and Landing
  • Level 2: TX 09.1 Aeroassist and Atmospheric Entry

Desired Deliverables of Phase I and Phase II:

  • Software
  • Prototype

Desired Deliverables Description:

The desired deliverable at the conclusion of Phase I is a prototype software package capable of accurately resolving gradient-based quantities such as heat flux and shear in the presence of strong shocks. The software shall demonstrate accurate prediction of surface heat flux for an Orion-like spherical heatshield in 2D at a variety of flight conditions without requiring adjustment of algorithm parameters. Surface heat flux predictions shall be verified by comparison with NASA's DPLR and/or LAURA simulation codes and must be free of numerical noise typically observed for second-order finite volume solvers on conventional unstructured grids. Real gas physics need not be included during Phase 1; perfect gas simulations are encouraged for expediency.

A successful Phase II deliverable will mature the Phase I prototype into a product ready for use on mission-relevant engineering problems. The software must be extended to 3D, parallelized for execution on large-scale supercomputers, and generalized to model multispecies and multitemperature gas physics. The software shall be demonstrated for complex vehicle geometries such as the Space Shuttle and exercised on a range of planetary entry problems that include at least two of the following destinations: Earth, Mars, Titan, Venus, and Uranus/Neptune. Computational performance, as measured by total time-to-solution for a given heat flux accuracy, shall be characterized and compared to DPLR/LAURA, but no specific performance targets are required.

State of the Art and Critical Gaps:

Current state-of-the-art engineering practice employs limited forms of mesh adaption, commonly referred to as "shock tailoring," whereby cell faces in a block-structured grid are aligned and clustered near the shock [2][3]. However, these approaches lack generality and can be difficult to employ in a robust manner for complex vehicle geometries.

Multiple academic [4,5,9,10] and NASA [11] groups have demonstrated promising results when using high order DG/FEM methods to perform steady state aerothermodynamic analysis at conditions relevant to planetary entry. However, most current research efforts in this area have focused on a simplistic model problem (heat flux on a sphere/cylinder at 5 km/s flight condition) with basic, nonionized flow models. An infusion of resources is needed to mature these promising algorithms into scalable, production-ready software that can be tested across a full entry trajectory with best-practice thermochemical models.

The current state of the art in anisotropic grid adaption as applied to EDL problems of interest is the Sketch-to-Solution capability based on FUN3D and refine [12], which has demonstrated the ability to accurately resolve integrated aerodynamic quantities (lift, drag, moment, etc.), but has yet to resolve the issue of noise in gradient based surface quantities (heat flux, shear), when using purely tetrahedral grids [13]. A variety of strategies exist to recover prismatic layers near the vehicle surface from anisotropic tetrahedral grids which can more accurately resolve the gradients at the wall [14] and at shocks [8]. Hybrid approaches where a prismatic boundary layer grid is utilized with anisotropic tetrahedra to resolve strong shocks have been demonstrated for various CFD solvers on EDL-relevant problems [15,16], but automation of this process as well as the challenges involved at the grid interface are still open problems.

Relevance / Science Traceability:

This scope is directly relevant to NASA space missions in both ESDMD-SOMD and SMD with an EDL segment. These missions depend on aerothermal CFD to define critical flight environments and would see significant, sustained reductions in cost and time-to-first-solution if an advanced grid adaption capability is developed. This scope also has strong crosscutting benefits for tools used by ARMD to simulate airbreathing hypersonic vehicles, which have stringent accuracy requirements similar to those in aerothermodynamics. Finally, this scope aligns with NASA’s CFD Vision 2030 Study, which calls for a “much higher degree of automation in all steps of the analysis process” with the ultimate goal of making “mesh generation and adaptation less burdensome and, ultimately, invisible to the CFD process.” In order for the aerothermal community to realize these goals, we must eliminate our dependence on manually designed, carefully tailored, block structured grids. This scope is an enabling technology for that transition. 

T10.05 Integrated Data Uncertainty Management and Representation for Trustworthy and Trusted Autonomy in Space

Scope Description:

Multi-agent cyber-physical-human (CPH) teams in future space missions must include machine agents with a high degree of autonomy. In the context of this subtopic, by “autonomy” we mean the capacity and authority of an agent (human or machine) for independent decision making and execution in a specified context. We refer to machine agents with these attributes as autonomous systems (AS). In multi-agent CPH teams, humans may serve as remote mission supervisors or as immediate mission teammates, along with AS. AS may function as teammates with specified independence, but under the ultimate human direction. Alternatively, AS may exercise complete independence in decision making and operations in pursuit of given mission goals; for instance, for control of uncrewed missions for planetary infrastructure development in preparation for human presence, or maintenance and operation of crew habitats during the crew’s absence.

In all cases, trustworthiness and trust are essential in CPH teams. The term “trustworthiness” denotes the degree to which the system performs as intended and does not perform prohibited actions in a specified context. “Trust” denotes the degree of readiness by an agent (human or machine) to accept direction or advice from another agent (human or machine), also in a specified context. In common sense terms, trust is a confidence in a system’s trustworthiness, which in turn, is the ability to perform actions with desired outcomes.

Because behind every action lies a decision-making problem, the trustworthiness of a system can be viewed in terms of the soundness of decision making by the system participants. Accurate and relevant information forms the basis of sound decision making. In this subtopic, we focus on data that inform CPH team decision making, both in human-machine and machine-machine interactions, from two perspectives: the quality of the data and the representation of the data in support of trusted human-machine and machine-machine interactions. 

Consider data exchanges in multi-agent cyber-physical-human (CPH) teams that include AS, as described in the subtopic introduction. Data exchanges in multi-agent teams must be subject to the following conditions:

  • Known data accuracy, noise characteristics, and resolution as a function of the physical sensors in relevant environments.
  • Known data accuracy, noise characteristics, and resolution as a function of data interpretation if the contributing sensors have a perception component or if data are delivered to an agent via another perception engine (e.g., visual recognition based on deep learning).
  • Known data provenance and integrity.
  • Dynamic anomaly detection in data streams during operations.
  • Comprehensive uncertainty quantification (UQ) of data from a single source.
  • Data fusion and combined UQ if multiple sources of data are used for decision making.
  • If data from either a single source or fused data from multiple sources are used for decision making by an agent (human or machine), the data and the attendant UQ must be transformed into a representation conducive to and productive for decision making. This may include data filtering, compression, or expansion, among other approaches.
  • UQ must be accompanied by a sensitivity analysis of the mission/operation/action goals with respect to uncertainties in various data, to enable appropriate risk estimation and risk-based decision making by relevant agents, human or machine.
  • Tools for real-time, a priori, and aposteriori data analysis, with explanations relevant to participating agents. For instance, if machine learning is used for visual data perception in decision making by humans, methods of interpretable or explainable AI (XAI) may be in order. 

We note that deep learning and machine learning, in general, are not the chief focus of this subtopic. The techniques are mentioned as an example of tools that may participate in data processing. If such tools are used, the representation of the results to decision makers (human or machine) must be suitably interpretable and equipped with UQ.

Addressing the entire set of the conditions listed above would likely be impractical in a single proposal. Therefore, proposers may offer methods and tools for addressing a subset of conditions.

Proposers should offer both a general approach to achieving a chosen subset of the listed conditions and a specific application of the general approach to appropriate data types. The future orbiting or surface stations are potential example platforms because the environment would include a variety of AS used for habitat maintenance when the station is uninhabited, continual system health management, crew health, robotic assembly, and cyber security, among other functions. However, the proposers may choose any relevant design reference mission for demonstration of proposed approaches to integrated data uncertainty management and representation, subject to a convincing substantiation of the generalizability and scalability of the approach to relevant practical systems, missions, and environments.

  • Level 1: TX 10 Autonomous Systems
  • Level 2: TX 10.1 Situational and Self Awareness

Desired Deliverables of Phase I and Phase II:

Desired Deliverables Description:

Since UQ and management in data is an overarching theme in this subtopic, an analysis of uncertainties in the processes and data must be present in all final deliverables, both in Phases I and II.

Phase I: For the areas selected in the proposal, the following deliverables would be in order:

  1. Thorough but succinct analysis of the state of the art in the proposed area under investigation.
  2. Detailed description of the problem used as the context for algorithm development, including substantiation for why this is a representative problem for a set of applications relevant to NASA missions.
  3. Detailed description of the approach, including pseudocode, and the attendant design of experiments for testing and evaluation.

  6. Preliminary demonstration of the software.
  7. Thorough analysis of performance and gaps.
  8. Detailed plan for Phase II, including the design reference mission and the attendant technical problem.
  9. Items 1 to 8 documented in a final report for Phase I.

  5. Resulting code.
  6. Detailed plan for potential Phase III.
  7. Items 1 to 5 documented in a final report for Phase II.

State of the Art and Critical Gaps:

Despite progress in real-time data analytics, serious gaps remain that will present an obstacle to the operation of systems in NASA missions that require heavy participation of AS, both in human-machine teams and in uncrewed environments, whether temporary or permanent. The gaps come under two main categories:

  1. Quality of the information based on various data sources—Trustworthiness of the data is essential in making decisions with desired outcomes. This gap can be summarized as the lack of reliable and actionable UQ associated with data, as well as the difficulty of detecting anomalies in data and combining data from disparate sources, ensuring appropriate quality of the result.
  2. Representation of the data to decision makers (human or machine) that is conducive to trustworthy decision making—We distinguish raw data from useful information of appropriate complexity and form. Transforming data, single-source or fused, into information productive for decision making, especially by humans, is a challenge.

Specific gaps are listed under the Scope Description as conditions the subsets of which must be addressed by proposers.

Relevance / Science Traceability:

The technologies developed as a result of this subtopic would be directly applicable to the Space Technology Mission Directorate (STMD), Science Mission Directorate (SMD), Exploration Systems Development Mission Directorate (ESDMD), Space Operations Mission Directorate (SOMD), and  Aeronautics Research Mission Directorate (ARMD), as all of these mission directorates are heavy users of data and growing users of AS. For instance, the Gateway mission will need a significant presence of AS, as well as human-machine team operations that rely on AS for habitat maintenance when the station is uninhabited, continual system health management, crew health, robotic assembly, among other functions. Human presence on the Moon surface will require similar functions, as well as future missions to Mars. All trustworthy decision making relies on trustworthy data. This topic addresses gaps in data trustworthiness, as well as productive data representation to human-machine teams for sound decision making.

The subtopic is also directly applicable to ARMD missions and goals because future airspace will heavily rely on AS. Thus, the subtopic is applicable to such projects as Airspace Operations and Safety Program (AOSP)/Advanced Air Mobility (AAM) and Air Traffic Management—eXploration (ATM-X). The technologies developed as a result of this subtopic would be applicable to the National Airspace System (NAS) in the near future as well, because of the need to process data related to vehicle and system performance.

Model-based anything (MBx) targets the use of models in any function that might include engineering, design, manufacturing, safety, testing and validation, operations, finance, human resources, facilities and infrastructure, and acquisition. Integration of models across multiple domains will enable the creation of model-based enterprise, which would facilitate high-complexity decision making by embodying agile processes to achieve efficiency, accuracy, confidence, and adaptability in support of NASA’s mission, programmatic development, digital transformation, and institutional activities. The model-based enterprise adopts modeling technologies to integrate and manage both technical and business processes related to various NASA missions. The MBx envisions a future where automated analyses and seamless information exchange among engineering, programmatic, and institutional domains enable informed decision making in real-time and engineering of novel systems. In this vision, complexity and capability will be an order of magnitude greater than current systems. Advances in artificial intelligence (AI), machine learning (ML), and deep learning along with MBx will be utilized to make engineering, program management, and institutional decisions. Transformation process efficiency gains can be realized as MBx reduces the effort, time, and cost to execute engineering, program management, and institutional processes.

Key technologies relevant to MBx include modeling and simulation, data analytics, process mining, AI and ML, digital twin, virtual reality (VR) and augmented reality (AR), metaverse, and digital thread. Integration of multiple technologies and interoperability of the tool set across multiple platforms and organizations are essential for the application of MBx to engineering and institutional functions. In addition, a robust MBx approach inherently depends on the ease of data transformation, which is significantly enhanced by the collaborative capabilities of the modeling tools used to create data and the standards used to exchange that data. There is a need for appropriate standards to ensure the seamless flow of data throughout the mission lifecycle and reusability of data.

This subtopic will focus on (1) development of the key technologies previously cited for engineering and business functions that can be integrated to create a model-based enterprise, (2) digital twins of engineering systems, facilities, and business functions, (3) application of VR/AR for engineering system development and operation of various physical assets on ground and in space, (4) application of metaverse for engineering development and operations, and (5) development of digital thread with seamless flow of data and models throughout the mission lifecycle.

Model-Based Enterprise, Digitally Interacting Comprehensive Frameworks and Models, and Automated Decision Making for Agency Operations

Scope Description:

Model-based enterprise targets the use of models in any function, from engineering to safety to finance to facilities and more (i.e., Model-Based "Anything" or MBx), to enable high-complexity decision making embodying agile processes to achieve efficiency, accuracy, confidence, and adaptability in support of NASA’s mission, programmatic development, and institutional activities.    

Consider an example of how Model-Based Systems Engineering (MBSE) is increasing in importance to future projects and programs as demonstrated by the strategic thrust towards "Model-Based Anything" of the Digital Transformation Initiative. At the same time, the nature of work at NASA is increasingly distributed with a workforce that may continue partial telework even after pandemic-related restrictions are relaxed.  

As previously indicated, the Agency will need to focus on efforts associated with the new changes in the "future of work" at NASA (Refs. 6 and 8). NASA will likely have fewer people working in buildings post-pandemic, and such buildings may be used differently than at present because many people will be working offsite and less frequently working in NASA facilities—except for special activities and needs. We will need to restructure our present older facilities for this type of change and/or plan to design differently for any new facilities, and we will need models for that.

NASA is seeking specific innovative, transformational, model-based solutions in the area of “Digital Twin” Institutional Management of Health/Automated Decision Support of Agency Facilities, which represents an opportunity to make revolutionary changes in how our Agency conducts business by investing in nascent technologies. The Agency’s newly minted Digital Transformation Office is interested in how to help reposition and accelerate the modernization of digital systems that support modernapproaches to managing the Agency's aging infrastructure. Recent initiatives in smart city technologies focus on condition-based/preventive maintenance, smart buildings, and smart lighting, which will address pressing Agency facility needs.

The STTR vehicle offers the small business community an opportunity to have a hand in this process towards repositioning and accelerating the modernization of digital systems supporting the Agency's aging infrastructure to:

  • Save energy costs due to water and electricity usage that is poorly measured and managed.
  • Enable the deployment of nascent technological trends in data-driven decision making and support tools based upon statistical methods to help streamline and improve the efficiency of facility operations and maintenance activities.
  • Determine how well technologies using techniques from the previous bullet can be broadly deployed across NASA. 
  • Enabling new agency-centric insight and management capabilities (building upon center models) to meet evolving future of work and other challenges in a more proactive and seamless manner.

At the conclusion of a Phase II effort, we anticipate that offerors should deliver a means to develop a model that is capable of context switching among various categorical factors established according to various levels of granularity including, but not limited to, the following: independent facility needs, facility inventory lifecycle balancing needs, workforce needs, etc.

For example, such a model should use past years' data to predict the condition of certain facility systems, and which ones should be invested in first for repairs to improve the return on investment (ROI) or improve the overall condition and reliability of the facility. A deferred maintenance assessment is conducted at NASA every year or on a 2- to 3-year cycle, where the inventory of buildings at every center is considered, for 27 systems total. A comparison of the current condition of those systems to previous years for each of those building systems is conducted. At the moment, there is a (sometimes categorical, sometimes numerical) mission dependency index (MDI) that comprises six factors (ref. 7), which is used to decide the highest priority for investments.

By the end of Phase II, offerors should have developed a model capable of identifying which of these 27 systems to invest in to increase the overall MDI. For example, given a specific building and the relative condition of its 27 systems, the model should make a recommendation on which systems to focus on for the highest ROI and fastest payback, as not all systems will feasibly be invested in for concurrent improvements.

The model should also be capable of the following:

  1. Identifying an optimal sequence of investments for which systems and which projects should be undertaken first.
  2. Be scalable and be capable of prioritizing project(s) by looking at 27 systems to identify the best investments based on a large number of buildings (e.g., 100 or more). 
  3. Capable of identifying macro-level systemic issues throughout the entire facility inventory from independent predictions made at the local level.

Several years worth of data (potentially up to 10 years) can be supplied to support the development of these enhanced features of such a model as well.  

However, it should be noted that it is easier to provide data for specific facility-level improvements rather than for facility inventory optimization due to the diverse and nontraditional set of facility functions that NASA as an Agency is challenged with due to unique mission needs and requirements. Data to support this type of macro-level analysis is not readily available, e.g., on the quality of the spaces.

However, at the local level, there are a limited number of high-performance modern facilities in the Agency that may offer very granular levels of detail to inform the development of a model that could effectively be used to address post-pandemic facility layout optimization needs, e.g., due to social distancing requirements, etc.

State of the Art and Critical Gaps:

Outside of NASA, industry is rapidly advancing Model-Based Systems Engineering (MBSE) tools and scaling them to larger, more complex development activities. Industry sees scaling as a natural extension of their ongoing digitization efforts. These scaling and extension efforts will result in reusable, validated libraries containing models, model fragments, patterns, contextualized data, etc. They will enable the ability to build upon, transform, and synthesize new concepts and missions, which has great attraction to both industry and government alike. Real-time collaboration and refinement of these validated libraries into either “single source” or “authoritative sources” of truth provide further appeal as usable knowledge can be pulled together much more quickly from a far wider breadth of available knowledge than was ever available before.

One example of industry applying MB/MBe/MBSE is through Digital Thread™, a communication framework that helps facilitate an integrated view and connected data flow of the product's data throughout its lifecycle. In other words, it helps deliver the right information at the right time and at the right place. Creating an “identical” copy (sometimes referred to as a "digital twin") is another use, a digital replica of potential and actual physical assets, processes, people, places, systems, and devices that can be used for various purposes. These twins are used to conduct virtual cost/technical trade studies, virtual testing, virtual qualification, etc., that are made possible through an integrated model-based network. Given the rise of MBSE in industry, NASA will need to keep pace in order to continue to communicate with industry, manage and monitor supply chain activities, and continue to provide leadership in spaceflight development.

Within NASA, our organization is faced with increasingly complex problems that require better and timelier integration and synthesis of both models and larger sets of data, not only in the systems engineering or MBSE realm, but in the broader MB Institution, MB Mission Management, and MB Enterprise Architecture. NASA is challenged to sift through and pull out the particular pieces of information needed for specific functions, as well as to ensure requirements are traced into designs, tested, and delivered; thus, confirming that the Agency gets what it has paid for. On a broader cross-agency scale, we need to ensure that needed information is available to support critical decisions in a timely and cost-effective manner. All of these challenges are addressed through the benefits of model-based approaches. Practices such as reusability, common sources of data, and validated libraries of authoritative information become the norm, not the exception, using an integrated, model-based environment. This model-based environment will contribute to a diverse, distributed business model encompassing multicenter and government-industry partnerships as the normal way of doing business.

Relevance / Science Traceability:

MBx solutions can benefit all NASA Mission Directorates and functional organizations. NASA activities could be a dramatically more efficient and lower risk through MBx support of more automated creation, execution, and completion verification of important agreements, such as international, supply chain, or data use.

Integration of Digital Twin With Augmented and Virtual Reality in Metaverse

Scope Description:

Digital twins is a critical emerging technology that consists of a physical asset, a virtual counterpart, and the data exchanged between the two. Enabled by models and simulations, advanced computing, and cyber and immersive technologies, digital twins tackle the challenge of integration between the physical and digital world, facilitating rapid analysis and real-time decision making. Digital twins transform the traditional design-build-test waterfall approach to a model-analyze-build-test spiral approach. This provides the capability to experiment, validate, and optimize solutions in the virtual space before building and testing, potentially jeopardizing the real-world asset. After a higher confidence design is built, measured test results can be used to update the model to forecast performance and evaluate risk of unforeseen operational scenarios. In the early stages of product/mission development, multiphysics models, simulations, and analytics (to include artificial intelligence (AI) and machine learning (ML)) can be used to conduct tradeoff analyses under various mission operating conditions and what-if scenarios in the virtual world. Insights can be obtained on manufacturability, cost, schedule, and performance by experimenting with a wide range of scenarios and evaluating optimized solutions and/or mitigation strategies. This results in significant reduction in time taken for development of design and new product/mission concepts. Digital twins can provide real-time monitoring, diagnostics, and corrective action for the operating assets. For operational assets like aircraft, spacecraft, habitats, power systems on lunar surface, planetary rovers, or large test facilities, digital twins fed by real-time sensor data on as-experienced environmental conditions can transform assumptions that drive the current scheduled and preventive maintenance practices to enable a more efficient predictive maintenance based on the actual condition of the operating asset.

The application of augmented and virtual reality (AR/VR) is undergoing significant growth for many engineering applications that include design and virtual testing of new products/concepts, manufacturing, and operations. The use of AR/VR allows designers, engineers, and end users to be immersed in a simulated environment (virtual reality) and in an environment where actual environments and objects are superimposed (augmented reality), or a hybrid between the two (mixed reality). By experiencing a new product in an immersive environment, designers and engineers can collaborate to accelerate the iterative product development process and reduce development costs. They can conduct research, design, modeling, prototyping, and user testing to validate ideas virtually in ways that would be too costly, impractical, or impossible to recreate in the real world.  Besides design and development of new products, AR/VR technologies are also used for training.

Integration of digital twins with AR/VR offers many benefits. Utilizing a virtual or augmented experience for digital twins allows stakeholders to digest, understand and visualize real-world depictions, and the ability to move and interact in these spaces. Digital twins integrated with AR/VR would provide virtual, behaviorally accurate representation of product designs and operating assets. By experiencing a component, subsystem, or system in an immersive environment along with the simulation tools associated with digital twins, engineers and designers can bring a product to life without physically constructing a single thing. An integrated digital twin-AR/VR system would allow training of operators for large facilities and manufacturing operations in a virtual dynamic environment, where they could practice responding to live operational conditions without risk to the asset or down time. 

While the computational tools for digital twins, real-time sensors, and AR/VR technologies have been developed in parallel and independent paths, the possibility of the combined use of these tools has grown. Typically, the simulation software used for digital twins lacks the AR/VR functionalities and lacks a mechanism to ingest live sensor data. It is timely to develop the connectivity between the digital twin, sensor data, and VR/AR software to take advantage of their strengths. It is envisioned the metaverse, which is rapidly evolving, will be the platform for integration of digital twins and live data with AR/VR. The metaverse will help recreate the existence of the real world digitally. For the integrated operational digital twin-AR/VR concept to be a reality, the necessary computational tools and architectures need to be developed to integrate digital twins and data streams with immersive technologies.

State of the Art and Critical Gaps:

One of the targets for NASA’s Digital Transformation (DT) strategic initiative is to transform engineering. Building blocks toward operational digital twins are currently being developed within NASA’s DT effort, with a goal of reducing time to develop new systems, significantly reducing time for anomaly detection in operating systems and enabling predictive maintenance of NASA facilities and infrastructure. Integration of operational digital twins with AR/VR technologies in metaverse will accelerate development of new aerospace systems and will offer engineers a better platform to share, interact, and collaborate with multiple partners. In addition, the integration of operational digital twins and AR/VR in the metaverse will enable training of new operators and engineers in large and complex test facilities. 

Relevance / Science Traceability:

Covers Aeronautics Research Mission Directorate (ARMD) priorities, such as zero-emission aircraft and green aviation as potential targets, along with OSI (Office of Strategic Infrastructure) priorities such as large test facilities and laboratories across the Agency, under the stewardship of the SETMO (Space Environments Testing Management Office). This would help with upskilling and training the current and future cohort of facility technicians and collaboration with external partners.

The objective of this subtopic is to develop and mature extended reality (XR) technologies that can support NASA's goal of a sustained presence on the Moon, the exploration of Mars, and the subsequent human expansion/exploration across the solar system. NASA’s current plans are to have boots on the surface of the Moon in late 2024. The initial lunar missions will be short in duration, provide limited objectives related to science and exploration and focus on the checkout of core vehicle systems. Over time, lunar, subsequent Mars, and other solar system exploration missions will be much longer, more complex, and face more challenges and hazards than were faced during the Apollo missions. These new missions will require that astronauts have the very best training, analysis tools, and real-time operations support tools possible because a single error during task execution can have dire consequences in the hazardous space environment.  Given the mission distances and mission durations, astronauts will also be required to function much more autonomously than they have had to function previously. Technologies, such as XR, that can improve training, operations support, health and medicine, and collaboration provide tools with capabilities that were not previously available, while also improving a crew's ability to carry out activities more autonomously. 

Training and operations support during the Apollo era required the use of physical mockups in laboratories, large hangars, or outdoor facilities. These training modalities had inherent detractors such as the background environments that included observers, trainers, cameras, and other objects. These detractors reduced the immersiveness and overall efficacy of the system. Studies show that the more “real” a training environment is, the better the training is received. This is because realism improves “muscle memory,” which is critically important, especially in hazardous environments. XR systems can be made that mitigate the distractors posed by observers, trainers, background visuals, etc., which was not possible in Apollo-era environments. The virtual environments that can be created are so “lifelike” that it can be extremely difficult to determine when someone is looking at a photograph of a real environment or a screen captured from a digitally created scene. XR systems also allow for training to take place that is typically too dangerous (e.g., evacuation scenarios that include fire, smoke, or other dangerous chemicals), too costly (buildup of an entire habitat environment with all their subsystems), not physically possible (e.g., incorporation of large-scale environments in a simulated lunar/Mars environment), and a system that is easily and much more cost effective to reconfigure for different mission scenarios (i.e., it is easier, quicker, and less expensive to modify digital content than to create or modify physical mockups or other physical components). Industry is using next-generation digital technologies to create XR-based digital twins that facilitate Product Lifecycle Management (PLM). Most of all, an XR-based digital ground replicate of the physical systems can serve as a common media (i.e., a “window”/viewpoint into the actual system) to communicate among all the stakeholders from different locations, sharing and interacting within the same virtual workspace simultaneously.

Given the increased duration, distances, and complexity of future missions, astronauts will also be required to function much more autonomously. XR can provide astronauts with tools that can improve an astronauts ability to function “more” autonomously by facilitating refresher training during missions, providing real-time operations support, allowing for the visualization of complex data, enhancing the collaboration environment, as well as between the mission participants and the support personnel back on Earth.

Although XR is being widely used in government and industry for an assortment of activities, XR technology is still being developed and maturing at an incredible pace. Capabilities that were only seen in video games or in movies are now part of enterprise-level applications. This fast growth presents challenges and opportunities to NASA. The challenge is the need to continually carry out horizon scans to stay up to date on the latest-and-greatest XR capabilities available.  This challenge is also an opportunity to help identify new capabilities that can help address some of the shortcomings/gaps associated with XR. These gaps can limit the use of the technology in certain use cases that are important to NASA, government, and industry in general. 

Extractable High-Resolution Terrain Database System

Scope Description:

The system would provide an extractable, high-resolution terrain database (<1 meter resolution) with all the correct metadata that is created from digital elevation terrain data, 3D rock models, 3D human-made structure models, photos, lidar scans, etc., that can be used with the most used game/scene rendering engines at NASA (Unreal, Omniverse, Unity, or Edge) to support the creation of highly immersive and highly performant simulation environments. The system should support large areas of interest >90 km, be able to ingest and store all the data needed to create the desired high-resolution/performant simulation environment, and output terrain data files at desired levels of detail, which can be used within the game/scene rendering engines mentioned above. The initial regions of interest are possible future NASA lunar landing sites, but the concept/system should be usable for Mars or other Earth locations of interest. The system should also provide a high level of automation that reduces the overall manual effort that is currently required to build these types of systems. Graphical user interfaces (GUIs) should be part of the system to facilitate the use of the system. This capability can be used to create an immersive environment to support training, collaboration, analysis, planning, and real-time operations of future Artemis missions.

Desired Deliverables Description:

Phase I awards will be expected to develop theoretical frameworks, algorithms, and demonstrate feasibility (Technology Readiness Level (TRL) 3) of the overall system (both software and hardware). Phase II awards will be expected to demonstrate the capabilities with the development of a prototype system that includes all the necessary hardware and software elements (TRL 6).

As appropriate for the phase of the award, Phases I and II should include all the algorithms and research results clearly depicting metrics and performance of the developed technology in comparison to state of the art (SOA). Software implementation of the developed solution along with the simulation platform must be included as a deliverable.

State of the Art and Critical Gaps:

Currently, the development of the products being requested from the system requires extensive manual, time-consuming steps that can be difficult to execute. The process that is typically followed requires users to search for all the data required to create the models. The data can include Digital Elevation Model (DEM), rock models, human-made structures, other features of interest, etc. Next, the developer manually adds metadata to the different models. The metadata can include geo-reference information, the size of the object, and any other features deemed important. Next, handcrafting is performed to assure that any digital elevation data models from all the sources are sized appropriately, color corrected, and inserted into the initial terrain models created from the DEM. Additional handcrafting is performed for certain models to assure that they have the resolution/fidelity required. Upon the integration of all the data sources, further handcrafting is required to assure that the system has the necessary multiresolution model features so that it can be rendered at the necessary frame rates. This is typically done by creating models at multiple resolutions. High-resolution models are used for areas near to the user and lower resolution models are used for regions further away from the user. As the user moves around, new high-resolution versions of the models are brought into the scene for the new area where the user is located and the high-resolution models for the area that the user just left is swapped out for lower resolution versions. This swapping of models is sometimes required to allow for the system to render the scene at the required frame rates.

The system proposed would include a central storage location where data can be retrieved from for the creation of the models. This central storage location would facilitate the integration of the data. The system would also automate many of the manual and time-consuming steps that are currently required. New methods that create higher fidelity models using photogrammetry or other model creation methods could also be integrated into the system.     

Current approaches NASA is using to develop the necessary 3D high-resolution models are time consuming and difficult to follow. As NASA continues to develop simulations for use on future missions, these capabilities will become more important. Having access to a system that can overcome some of the challenges will be increasingly more important.

Augmented Reality Navigation

Scope Description:

The system should provide google maps style navigation outdoors and also inside of buildings. The system will allow for AR applications to be developed that do not require QR style visual markers, while still providing highly accurate six degrees of freedom position (6DOF) (< 1 cm); as well as highly accurate altitude and attitude information. The system should be usable with smart devices (tablets, smartphones) that support both iOS and Android operating systems. The system should also support with head worn AR devices. This type of system will allow for AR applications to be developed that can be used to accurately overlay points of interest and meta-information about those points of interest. The system allows for creation of applications that can be used to carry out activities more autonomously by allowing the system to guide a user through unfamiliar facilities and through steps that are required to carry out procedures.

State of the Art and Critical Gaps:

Industry has made significant progress developing markerless navigation technologies. These technologies are typically used on smartphones/tablets and require calibration steps for their use.  A key player in the outdoor AR navigation field is the automobile industry, where navigation information can be displayed directly on the windshield or on a screen that the driver has a direct line of sight. A significant user of indoor navigation technologies includes warehouses, where people can be guided to certain locations to find items. Improvements to both the indoor and outdoor AR navigation system is important, since NASA has use cases for both indoor and outdoor AR navigation.  

Current gaps that should be addressed for future systems include the overall use of the technology on head-worn devices, along with smartphone/tablets.   Additionally, the accuracy of the system should be improved to allow NASA to use the capability to support indoor electronic procedure use cases that require high precision 6DOF data.  How one should interact with the AR navigation systems (i.e., the GUIs and other human interface methods that users will use to interact with the system) should also be investigated further.

Being able to have head-up displays (HUDs) in a helmet bubble, head-mounted displays (HMDs), or windshields that provide navigation cues to locations of interest or augment those locations with additional information will be important in the future design of next generation vehicles and suits.  Furthermore, navigation aids will augment an astronaut's ability to carry out medical procedures more autonomously.  It will also allow for certain procedures to be carried out that would not otherwise be possible by providing instructions on the exact placement and movement of medical instruments.  Any system that reduces risks, improves operations, and allows for more autonomous operations are important for many different NASA directorates that includes ESDMD, SOMD, STMD, and SDM.  Artemis and Gateway programs will also be able to infuse these technologies into future missions.

T12.01 Additive Manufactured Electronics for Severe Volume Constrained Applications

Scope Description:

The field of Additively Manufactured Electronics (AME) has been evolving and can provide enabling capability for future NASA missions that have very severe or unique volume constraints. Several concepts for NASA missions or mission concepts in the decadal survey where these volume constraints can be major technical constraints are advanced mobility concepts [1], atmosphere probes, and Instruments/Subcomponents of Ocean World Landers. Some of the electronics in these missions will likely need to go below cold survival temperatures associated with warm electronics boxes (i.e., colder than -35 °C). Methods of using AME to create circuits in a compact 3D structure or involving nonplanar surfaces (such as a cylinder) are both of interest [2,3]. There have been multiple works that demonstrate the capability of AME for 3D and nonplanar circuitry but limited work that demonstrates its effectiveness for space applications. The AME approach should address the following technical and mechanical challenges:

  1. AME methodology should include integration of a variety of standard electronics package types including ball grid arrays (BGAs), quad flat pack nonleaded (QFN)/land grid array (LGA), and chip components.
  2. AME circuit should show the capability of surviving the thermal requirements needed for space missions with -35 to 100 °C nonoperational as a minimum criterion and ability to survive extreme cold (such as -125 °C) as a desired capability.
  3. The AME approach should show the capability of favorable cost and schedule compared to equivalent approaches using traditional electronics manufacturing and demonstrate repeatability/accuracy.

Desired Deliverables of Phase I and Phase II:

Desired Deliverables Description:

  • Sets of materials and manufacturing techniques that are able to create robust circuitry using printed electronics for volume constrained applications. Material sets and methodologies should be readily available for NASA centers to use on application-specific designs to meet future packaging needs.
  • The Phase I deliverables should be fabrication of standalone critical structures and demonstration of approaches to scale to fully functional compact circuits.  
  • The Phase II deliverables should include the design and fabrication of full circuits. Testing should demonstrate the reliability of AME structures as well as functional performance of the structures. Materials and manufacturing techniques should be formulated and available at small scale for application-specific designs.

State of the Art and Critical Gaps:

Numerous published works have shown multiple material and manufacturing methods able to print conductors and dielectrics at needed resolutions. There are also multiple published examples where nonplanar or 3D circuits have been fabricated. The current set of work shows lack of data demonstrating the reliability of these circuits in environments relevant to NASA. Also, the current body of work shows circuits with small numbers of parts and does not demonstrate the repeatability/reproducibility desired for more complex 3D/nonplanar circuits.  

Relevance / Science Traceability:

Use of AME is relevant to Exploration Systems Development Mission Directorate (ESDMD), Space Operations Mission Directorate (SOMD), Science Mission Directorate (SMD), and Space Technology Mission Directorate (STMD), all of which have extant efforts in additive manufacturing. Several efforts involving NASA and aerospace companies have used AME on the space station (including major work from NASA centers on fabrication of circuits in space). Future AME missions where there are extreme volume constraints include components of landing systems, probes, and mobility systems that are needed to meet SMD and STMD goals.

Fabrication and assembly of structural systems using advanced construction techniques, including habitats, pressure vessels, and other nonpressurized structures from extraterrestrial materials. Materials extracted from in situ lunar and planetary resources (e.g., the minerals present on the surface, atmosphere, or vapor deposits) have the potential to radically reduce the cost and increase the scale of ambitious future space exploration activities. The design and fabrication of such systems and associated technologies so that construction and outfitting can be effectively accomplished locally is essential to their utilization—including integration of systems such as pumps and valves, airlocks, life support, health management sensors and controls, and others, in addition to structural foundations.

Materials, components, and systems that would be necessary for the proposed technology must be able to operate on the lunar surface in temperatures of up to 110 °C (230 °F) during sunlit periods and as low as -170 °C (-274 °F) during periods of darkness. Systems must also be able to operate for at least 1 year with a goal of 5 years without substantial maintenance in the dusty regolith environment. Proposers should assume that operations involving other systems (e.g., robots) and later astronauts will be ongoing not more than tens of meters away from the local fabrication, construction, and/or outfitting activities. Phase I efforts can be demonstrated at any scale; Phase II efforts must be scalable up to 100-1,000 m3 of fabricated pressure vessel, and not less than 10 meters of single structural system element.

Each of the following specific areas of technology interest may be developed as a standalone technology.

Phase I should focus on development of reinforcement techniques and concepts for experimentation and testing of different techniques with in situ material to determine viability for use on planetary surfaces and a future flight demonstration mission(s). Outcome: Phase I results should be documented in a report back to the government. Phase II deliverables must be capable of demonstration in terrestrial simulation chambers and technology transfer to a small business for development for flight demonstration and lunar tests. Proposals should also address the technology transfer to a small business that will develop the technology and integrate it into a lunar flight demonstration mission.

T12.09 Carbon Fiber Reinforced Thermoplastic Composites for Repurposable Aerospace Applications

Scope Description:

This solicitation seeks to exploit unique properties of thermoplastic composites to assess their feasibility and propose concepts of operations for in situ repurposing of primary and secondary spacecraft structures into deep space exploration infrastructure supporting sustainable human presence beyond low Earth orbit (LEO). For the purpose of this solicitation, the term "infrastructure" encompasses tools that can be used for excavation, construction, and outfitting [1]. The original spacecraft (e.g., lander or descent module) components would be designed with future repurposing requirements accounted for in the initial design objectives. Once the spacecraft would accomplish its mission (e.g., successfully descended onto the lunar surface), its parts would be disassembled and reconfigured into infrastructure components and/or tools by reheating thermoplastic resin [2], first consolidated during original manufacturing prior to launch, and mechanically modifying the structure into a predetermined repurposed configuration.

NASA is developing long-duration, crewed missions to the Moon and beyond. These missions will require crew habitats and, consequently, sourcing materials to construct them and the associated infrastructure, such as storage, surface transportation, and means of communications. Use of in situ resources (e.g., lunar regolith) and reuse of descent vehicles have already been proposed as a means of reducing the amount of material needing to be delivered as payload for sustainable human presence. The ability to repurpose components of spacecraft structures, via additive manufacturing or other methods, is one potential benefit of using carbon fiber reinforced thermoplastic composites [3, 4]. Thermoplastics also offer the potential to be easily repaired via a reheating process in the event of in-service damage [5].

To reliably assess the feasibility of repurposing thermoplastic composites for space applications, both modeling and simulation (M&S), as well as experimental work, needs to be conducted in a building block approach. In Phase I, the proposing team shall select a focus structure where the original geometric configuration and a repurposed configuration are defined along with the corresponding sizing load cases. Repurposing lunar lander fairings and/or components of the micrometeoroid and orbital debris (MMOD) protective structure into a regolith mining scoop, or repurposing primary truss structure into an antenna post are examples provided here for illustration purposes only, and the proposing team is encouraged to survey and offer other applications of their choosing. A selected study case shall exemplify repurposing both from the standpoint of altered geometry and distinct loads and environment. Once the two “stand-alone” cases (original and repurposed) are sized and analyzed, a multiphysics simulation of the repurposing process shall be conducted. Exploring repurposing process sensitivity to different process parameters shall be leveraged to arrive to the final repurposing concept of operations and establish the energy required for the repurposing process. Heating methods shall be explored and include external and internal (pre-embedded) heating devices. Furthermore, the simulation shall establish tradeoffs associated with conducting the repurposing process with and without dedicated tooling aids. Success metrics should include a maximum weight penalty of 15% after repair, while still maintaining 100% load-carrying capability.

These efforts will establish a foundation for hardware demonstrations to be conducted in Phase II. Test data obtained from these demonstrations will be used to calibrate the multiphysics repurposing simulation framework to enable detailed repurposing assessment and mitigate prominent risks.

State of the Art and Critical Gaps:

State of the Art and Critical Gaps:

Present composite designs mainly use thermoset materials, which have limited manufacturing rates, are difficult to repair, and can lack the desired tailorability for advanced structures. There is a need for advanced materials that can be used to increase performance and decrease manufacturing and repair demands for in-space applications.

Relevance / Science Traceability:

At the completion of Phase II, the program will gain understanding of where the implementation of repurposed carbon fiber reinforced thermoplastic composites can be most advantageous in deep space structural applications, how such a repurposing can be accomplished (concept of operations), and what are the metrics that can be used in assessing feasibility of repurposing. Additionally, the technology gaps limiting even broader implementation of repurposed thermoplastic composites can be identified. This solicitation supports the Langley Strategic Technology Investment Plan [1] in the areas of “Safe Human Travel Beyond Low Earth Orbit (LEO)” and “On-orbit Servicing, Assembly, and Manufacturing (OSAM).”

Thermoplastic composites offer the potential for lightweight composite structures to be repurposed, in contrast to state-of-the-art composites, which are generally made with thermoset resins. This supports applications like the Artemis mission, where in situ resources, among which are structures from objects like descent modules, become part of native resources that can be used to create infrastructure.

Examples of potential uses include Space Technology Mission Directorate, Artemis/Human Landing System (HLS) programs, Aeronautics Research Mission Directorate, next-generation airframe technology beyond "tube and wing" configurations (e.g., hybrid/blended wing body or transonic truss-braced wing), and the Hi-rate Composite Aircraft Manufacturing (HiCAM) program.

T13.01 Intelligent Sensors for Rocket Propulsion Testing

Scope Description:

Rocket propulsion system development is enabled by rigorous ground testing to mitigate the propulsion system risks inherent in spaceflight. Test articles and facilities are highly instrumented to enable a comprehensive analysis of propulsion system performance. Intelligent sensor systems have the potential for substantial reduction in time and cost of propulsion systems development, with substantially reduced operational costs and evolutionary improvements in ground, launch, and flight system operational robustness.

Intelligent sensor systems would provide a highly flexible instrumentation solution capable of monitoring test facility parameters including temperature, pressure, flow, vibration, and/or storage vessel liquid level. Sensor systems should enable the ability to detect anomalies, determine causes and effects, predict future anomalies, and provide an integrated awareness of the health of the system. These intelligent sensors should also be capable of performing in-place calibrations with National Institute of Standards and Technology (NIST) traceability and onboard conversion of raw sensor data to engineering units. The intelligent sensor system must also provide conversion of raw sensor data to engineering units, synchronization with Inter-Range Instrumentation Group—Time Code Format B (IRIG-B), as well as network connectivity to facilitate real-time integration of collected data with data from conventional data acquisition systems.

This subtopic seeks both wired and wireless solutions to address the need for intelligent sensor systems to monitor and characterize rocket engine performance.  Wireless sensors are highly desirable and offer the ability to eliminate facility cabling/instrumentation, which can significantly the reduce the cost of operations.  It also provides the capability for providing instrumentation in remote or hard to access locations.  These advanced wireless instruments should function as a modular node in a sensor network, capable of performing some processing, gathering sensory information, and communicating with other connected nodes in the network.

Rocket propulsion test facilities also provide excellent testbeds for testing and using the innovative technologies for possible application beyond the static propulsion testing environment. It is envisioned this advanced instrumentation would support sensing and control applications beyond those of propulsion testing. For example, inclusion of expert system and artificial intelligence technologies would provide great benefits for autonomous operations, health monitoring, or self-maintaining systems.

This subtopic seeks to develop advanced intelligent sensor systems capable of performing onboard processing utilizing artificial intelligence to gauge the accuracy and health of the sensor. Sensor systems must provide the following functionality:

  • Assess the quality of the data and health of the sensor.
  • Perform in-place calibrations with NIST traceability.
  • Data acquisition and conversion to engineering units for monitoring temperature, pressure, flow, vibration and/or storage vessel liquid level within established standards for error and uncertainty.
  • Function reliably in extreme environments, including rapidly changing ranges of environmental conditions, such as those experienced in space. These ranges may be from extremely cold temperatures, such as cryogenic temperatures, to extremely high temperatures, such as those experienced near a rocket engine plume. Sensor operational environmental parameters must be suitable for the anticipated environment, e.g., extreme temperature (cryogenic or high heat), high vibration, flammable, etc.
  • Collected data must be time-stamped to facilitate analysis with other collected datasets.
  • Provide network connectivity to facilitate real-time transfer of data to other systems for monitoring and analysis.

Expected TRL or TRL Range at completion of the Project: 3 to 6

Primary Technology Taxonomy:

  • Level 1: TX 13 Ground, Test, and Surface Systems
  • Level 2: TX 13.1 Infrastructure Optimization

Desired Deliverables of Phase I and Phase II:

  • Prototype
  • Hardware
  • Software

Desired Deliverables Description:

For all above technologies, research should be conducted to demonstrate technical feasibility with a final report at Phase I and show a path towards Phase II hardware/software demonstration with delivery of a demonstration unit or software package for NASA testing at the completion of the Phase II contract.

State of the Art and Critical Gaps:

Highly modular, intelligent sensors are of interest to many NASA tests and missions. Real-time data from sensor networks reduces risk and provides data for future design improvements. Intelligent sensor systems enable the ability to assess the quality of the data and health of the sensor, increasing confidence in the system. They can be used for thermal and pressure measurement of systems and subsystems and also provide emergency system halt instructions in the case of leaks or fire. Other examples of potential NASA applications include (1) measuring temperature, voltage, and current from power storage and generation systems, (2) measuring pressure, temperature, vibrations, and flow in pumps, and (3) measuring pressure, temperature, and liquid level in pressure vessels.

There are many other applications that would benefit from increased real-time intelligent sensors. For example, these sensors would be capable of addressing multiple mission requirements for remote monitoring such as vehicle health monitoring in flight systems and autonomous vehicle operation. This data is used in real time to determine safety margins and test anomalies. The data is also used post-test to correlate analytical models and optimize vehicle and test design. Because these sensors are small and low mass, they can be used for ground test and for flight. Sensor module miniaturization will further reduce size, mass, and cost.

No existing intelligent sensor system option meets NASA’s current needs for flexibility, size, mass, and resilience to extreme environments.

Relevance / Science Traceability:

This subtopic is relevant to the development of liquid propulsion systems development and verification testing in support of the Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate (SOMD). It supports all test programs at Stennis Space Center (SSC) and other propulsion system development centers. Potential advocates are the Rocket Propulsion Test (RPT) Program Office and all rocket propulsion test programs at SSC.

Advanced Concepts for Lunar and Martian Propellant Production, Storage, and Usage

Scope Description:

This subtopic seeks technologies related to cryogenic propellant (e.g., hydrogen, oxygen, and methane) production, sensors and instrumentation, storage, and usage to support NASA's in-situ resource utilization (ISRU) goals. This includes a wide range of applications, scales, and environments consistent with future NASA missions to the Moon and Mars. Anticipated outcomes of Phase I proposals are expected to deliver proof of the proposed concept with some sort of basic testing or physical demonstration. Proposals shall include plans for a prototype and demonstration in a defined relevant environment (with relevant fluids) at the conclusion of Phase II. Solicited topics are as follows:

  • Development of instruments and instrument components suitable for use with lunar regolith. The successful deployment of ISRU technology on the Moon requires processing industrial-scale amounts (thousands of metric tons) of lunar regolith to extract trapped water and/or oxygen. To narrow the critical gaps between the current state of art and the need for sensors in extreme environments, technologies are being sought to increase the robustness and processing speed required for wide area and localized resource assessment. Sensors need to operate for long term (>200 days) in harsh abrasive and thermal environments in both sunlit and permanently shadowed regions, which risks calibration/measurement drift, accuracy decline, or contaminant failure. Most favorable sensors will have low mass, volume, and/or power requirements. Sensor selectivity, dynamic range, and response time appropriate for the targeted resource processing is needed. Proposers should show an understanding of relevant environmental capability, present a feasible plan to fully develop a technology, and infuse it into a NASA program. Proposer should provide a comparison metric for assessing proposed improvements compared to existing capabilities. The proposer should clearly describe the ISRU process targeted, the rationale for the sensor technology proposed, and a clear justification that the proposed technology will have an impact on ISRU processing.
    •  
      • Sensors to determine regolith mineral/chemical composition during transfer for processing: While science instruments have been developed for mineral/chemical composition, instruments need to be refocused for (1) lunar operation, (2) minerals of resource interest, and (3) faster operation. Sensors are needed to better understand minerology during regolith processing (mass flows >1 kg/hr).
      • Sensors for evaluating regolith properties during transfer for preparation and processing: ISRU systems that process resources will need a near-real-time understanding of feed size, shape, and mass flow (>1 kg/hr) to optimize performance. This means that the regolith transfer device needs the ability to support instruments that operate in an abrasive environment that can be used before and/or after regolith preparation (crushing and size sorting) and before transfer for processing.
      • Sensors to monitor ISRU process gases: ISRU processes need to measure O2, H2, and CH4 at high concentrations of the gas; for contaminants including H2O impurities, CO, CH4, H2, HF, HCl, H2S, etc., and crossover gases on alternative lines (eg., H2 on O2 side), measurement is likely needed at ppm levels.
  • Develop and implement computational methodology to enhance the evaluation of temperature and species gradients at the liquid/vapor interface in unsettled conditions. Techniques could include arbitrary Lagrangian-Eulerian (ALE) interface tracking methods with adaptive mesh morphing, interface reconstruction methods, immersed boundary approaches, or enhanced-capability level set and volume of fluid (VOF) scheme that decrease numerically generated spurious velocities and increase gradient evaluation accuracy. The uncertainty of such techniques in determining the interfacial gradients should be <5% and on par with accuracies of a sharp interface method applied to a nonmoving, rigid interface. Applications include cryogenic tank self-pressurization, pressure control via jet mixing, and filling and liquid transfer operations. It is highly desirable if the methodology can be implemented via user-defined functions/subroutines into commercial computational fluid dynamics (CFD) codes. The final deliverable should be the documentation showing the detailed formulation, implementation, and validation, and any stand-alone code or customized user-defined functions that have been developed for implementation into commercial codes.

Expected TRL or TRL Range at completion of the Project: 2 to 4

Primary Technology Taxonomy:

  • Level 1: TX 14 Thermal Management Systems
  • Level 2: TX 14.1 Cryogenic Systems

Desired Deliverables of Phase I and Phase II:

  • Hardware
  • Software
  • Prototype

Desired Deliverables Description:

Phase I proposals should at a minimum deliver proof of the concept, including some sort of testing or physical demonstration, not just a paper study. Phase II proposals should provide component validation in a laboratory environment preferably with hardware (or model subroutines) deliverable to NASA.

Deliverables for the modeling: Phase I should demonstrate the accuracy of the method for simulating self-pressurization under unsettled, low-gravity conditions. Phase II should demonstrate the accuracy of the method for simulating jet mixing and filling and transfer operations. The final deliverable should be the documentation showing the detailed formulation, implementation, and validation, and any stand-alone code or customized user-defined functions that have been developed for implementation into commercial codes.

Deliverables for the sensors: The Phase I project should focus on feasibility and proof-of-concept demonstration (Technology Readiness Level (TRL) 2-3). The required Phase I deliverable is a report documenting the proposed innovation, its status at the end of the Phase I effort, and the evaluation of its strengths and weaknesses compared to the state of the art. The report can include a feasibility assessment and concept of operations, simulations and/or measurements, and a plan for further development to be performed in Phase II.

The Phase II project should focus on component and/or breadboard development with the delivery of specific hardware for NASA (TRL 4-5). Phase II deliverables include a working prototype of the proposed hardware, along with documentation of development, capabilities, and measurements.

State of the Art and Critical Gaps:

NASA's Space Technology Mission Directorate (STMD) has identified ISRU as a main investment area in its strategic framework. Scalable ISRU production and utilization capabilities including sustainable commodities are required to live on the lunar and Mars surfaces. The required commercial-scale water, oxygen, and metals production will be demonstrated at a smaller scale via a pilot production plant envisioned in the 2030s.

Cryogenic Fluid Management (CFM) is a cross-cutting technology suite that supports multiple forms of propulsion systems (nuclear and chemical), including storage, transfer, and gauging, as well as liquefaction of ISRU-produced propellants. The STMD has identified that CFM technologies are vital to NASA's exploration plans for multiple architectures, whether it is hydrogen/oxygen or methane/oxygen systems including chemical propulsion and nuclear thermal propulsion. 

Relevance / Science Traceability:

NASA's STMD has identified ISRU as a main investment area in its strategic framework. Additionally, NASA has plans to purchase services for delivery of payloads to the Moon through the Commercial Lunar Payload Services (CLPS) contract. The CLPS payload accommodations will vary depending on the particular service provider and mission characteristics. CLPS missions will typically carry multiple payloads for multiple customers and may include commodity production technology demonstrations. Additional information on the CLPS program and providers can be found at this link:  https://www.nasa.gov/content/commercial-lunar-payload-services

STMD strives to provide the technologies that are needed to enable exploration of the solar system, both manned and unmanned systems, and CFM is a key technology to enable exploration. Whether liquid oxygen/liquid hydrogen or liquid oxygen/liquid methane is chosen by the Exploration Systems Development Mission Directorate (ESDMD) and Space Operations Mission Directorate (SOMD)  as the main in-space propulsion element to transport humans, CFM will be required to store propellant for up to 5 years in various orbital environments. Transfer will also be required, whether to engines or other tanks (e.g., depot/aggregation), to enable the use of cryogenic propellants that have been stored. In conjunction with ISRU, cryogens will have to be produced, liquefied, and stored, the latter two of which are CFM functions for the surface of the Moon or Mars. ISRU and CFM liquefaction drastically reduces the amount of mass that has to be landed on the Moon or Mars.

T15.04 Full-Scale (Passenger/Cargo) Electric Vertical Takeoff and Landing (eVTOL) Scaling, Propulsion, Aerodynamics, and Acoustics Investigations

Scope Description:

NASA's Aeronautics Research Mission Directorate (ARMD) laid out a Strategic Implementation Plan for aeronautical research aimed at the next 25 years and beyond. The documentation includes a set of Strategic Thrusts—research areas that NASA will invest in and guide. It encompasses a broad range of technologies to meet future needs of the aviation community, the nation, and the world for safe, efficient, flexible, and environmentally sustainable air transportation. Furthermore, the convergence of various technologies will also enable highly integrated electric air vehicles to be operated in domestic or international airspace. This subtopic supports ARMD’s Strategic Thrusts #4 (Safe, Quiet, and Affordable Vertical Lift Air Vehicles) as well as #1 (Safe, Efficient Growth in Global Operations) and #3 (Ultra-Efficient Subsonic Transports). 

Proposals are sought in the following areas: (1) design and execution of experiments to gather research-quality data to validate aerodynamic and acoustic modeling of full-scale, multirotor eVTOL aircraft, with an emphasis on rotor interactions with airframe components and other rotors and propellers and (2) development and validation of scaling methods for extending and applying the results of instrumented subscale model testing to full-scale applications. 

This solicitation does not seek proposals for designs or experiments that do not address full-scale applications. Full-scale is defined as a payload capacity equivalent to two or more passengers or equivalent cargo, including any combination of pilots, passengers, and/or ballast.

Although eVTOL is preferred, electric short takeoff and landing (eSTOL) vehicle configurations are acceptable.

Proposals should address the following if applicable:

(1) Clearly define the data that will be provided and how it will help NASA and the community accelerate the design cycle of full-scale eVTOL aircraft. Also, proposals should define what data will be collected and data that will be considered proprietary. Data includes vehicle specifications, models, results, flight test data, and any other information relative to the work proposed.

(2) If the proposal cannot address the full topic, please state a reasoning/justification.

(3) Clearly propose a path to commercialization and include detail with regards to the expected products, data, stakeholders, and potential customers.

State of the Art and Critical Gaps:

Integration of distributed electric propulsion (DEP) (4+ rotors) systems into advanced air mobility eVTOL aircraft involves multidisciplinary design, analysis, and optimization (MDAO) of several disciplines in aircraft technologies. These disciplines include aerodynamics, propulsion, structures, acoustics, and/or control in traditional aeronautics-related subjects. Innovative approaches in designing and analyzing highly integrated DEP eVTOL aircraft are needed to reduce energy use, noise, emissions, and safety concerns. Such advances are needed to address ARMD’s Strategic Thrusts #1 (Safe, Efficient Growth in Global Operations), #3 (Ultra-Efficient Subsonic Transports), and #4 (Safe, Quiet, and Affordable Vertical Lift Air Vehicles). Due to the rapid advances in DEP-enabling technologies, current state-of-the-art design and analysis tools lack sufficient validation against full-scale eVTOL flight vehicles, especially in the areas of aerodynamics and acoustics. Ultimately, the goal is to model and test multidisciplinary aeropropulsive acoustics.

Relevance / Science Traceability:

This subtopic primarily supports ARMD’s Strategic Thrust #4 (Safe, Quiet, and Affordable Vertical Lift Air Vehicles), although it also yields benefits for Thrusts #1 (Safe, Efficient Growth in Global Operations) and #3 (Ultra-Efficient Subsonic Transports). Specifically, the following ARMD program and projects are highly relevant.

This subtopic is highly relevant and facilitates further research and opportunities to small businesses and research institutions. Under the umbrella of air taxis, eVTOL could create a market worth trillions of dollars in the next 15 to 20 years according to some market reports and predictions. Although aerodynamics and acoustics are the focus of this subtopic, facilitating flight testing of these vehicles provides platforms for many small business opportunities, including development and marketing of subsystems and support infrastructure such as batteries, electric motors, propellers, rotors, instrumentation, sensors, manufacturing, vehicle support, vehicle operations, and many more.

Ground Operations and Services/Launch Services Topic Areas

Proposed topics originated from the Human Explorations and Operations (HEO) Capability Gap action that had the most urgent safety need, under Ground Operations and Services/Launch Services. Topic areas are:

With an increasing number of LOX/methane rockets being developed for use, there is an increasing need for a standard for on-site storage of methane. The NASA standard for hydrogen storage is based on a report characterizing hazards from vapor cloud explosions and radiative heat flux and the resultant separation distances. A similar standard should be developed using existing literature about gaseous methane/air reactions and typical process controls for liquified methane storage. Results from this project could be used to inform a new NASA
standard.

Liquified methane and liquid oxygen is becoming more common as fuel for rockets. This fuel has the potential to form a miscible methane-oxygen solution (MOX) that can ignite in the liquid phase, causing significant hazard potential. There is more to be learned about MOX formation and ignition sources/limits. Currently, existing questions center around what credible ignition sources are, how much of a given ignition source is required for detonation, and how different mixtures, temperatures, and pressures can affect the resultant reaction.

Translational Research Institute for Space Health Topic Areas
The Translational Research Institute for Space Health (TRISH) is an applied space health research catalyst that funds disruptive, high-impact scientific studies and technologies to equip astronauts for deep space exploration. Founded on October 1, 2016, TRISH works in partnership with NASA’s Human Research Program (HRP) through Cooperative Agreement NNX16AO69A.

Connecting TRISH to these Topics
TRISH relentlessly pursues and funds novel research to deliver high-impact scientific and technological solutions that advance space health and help humans thrive wherever they explore, in space or on Earth. TRISH is interested in the analysis of overlap between terrestrial health and tools, techniques, or processes that could be used to advance space health. For more information about discipline areas that present a risk or challenge to human health and performance in space, please see the NASA Human Research Program Human Research Roadmap (HRP HRR). Topic areas from the Transnational Research Institute for Space Health are:

Currently astronauts on the International Space Station (ISS) have relatively quick access to many medical supplies and the ability to talk to health care professionals on the ground. This will not as easily be the case for future missions beyond low earth orbit (LEO). Astronauts will be required to bring everything that they might need for medical care with them on an exploration mission. Medical technologies that are low footprint and easy to use and transport are ideal for spaceflight. This would mean a technology that has low mass and requires minimal volume and power to operate. All projects focused on learning how advances in space health can impact and improve health delivery on Earth are appropriate and thus, making connections between space and terrestrial health is encouraged. If applicants are interested, they may be able to discuss access to already collected tissue samples, animal data or de-identified astronaut lifetime monitoring data for analysis.
 

Respondents can propose the following types of activities:

  1. Conduct a short proof-of-concept experiment for existing techniques or technologies that are developed for Earth but may be useful in space and used as justification for future studies and grant applications;
  2. Obtain relevant preliminary data that can be used in a future grant application;
  3. Conduct a literature review to familiarize the investigator team with NASA’s perspective and the framing of a “risk.” This work will be helpful to identify how the team’s current research could apply in space health and be used to inform a future grant application. It is encouraged that this effort culminates in a publication where applicable. It is recommended that funds are protected for this purpose. 

It is expected that the applicant plan to attend 1-2 workshops. It is recommended that funds are protected for these networking possibilities. Two workshops of interest are; (1) The NASA HRP Investigators’ Workshop in late January or early February in Galveston, TX (required), and (2) a TRISH Diversity Program-supported workshop at a to be determined location.

We often study disease states here on Earth but space presents a unique opportunity to study very healthy individuals that are impacted by an extremely unique and stressful environment in which some symptoms of disease states manifest but often do not continue upon return to Earth. It would be of interest to understand the health state of a patient before the actual disease presents itself. This type of understanding will help us to better understand these, somewhat, transient effects of spaceflight and how to minimize and prevent them. All projects focused on learning how advances in space health can impact and improve health delivery on Earth are appropriate and thus, making connections between space and terrestrial health is encouraged. Applicants are encouraged to explore unique uses of technology such as tissue chips.

Crewmembers on space flights are faced with multiple environmental, physiological and psychosocial stressors including but not limited to: microgravity, disrupted circadian rhythms, elevated exposure to radiation, increased carbon dioxide levels, and separation from friends and family. Careful selection of resilient individuals and rigorous training prepares the crew for such stresses and most adapt well, performing adeptly despite suboptimal conditions. However, deep space exploration missions will require the crew to contend with such stresses for 30 months without the possibility of immediate return to Earth. NASA has considered the inclusion of psychoactive medications for this purpose; however, drug expiration dates shorter than the mission lengths and the pharmacokinetics of drug administration in microgravity is poorly understood making a non-pharmacological methods for maintaining health and cognitive performance under stressful conditions desirable. All projects focused on learning how advances in space health can impact and improve health delivery on Earth are appropriate and thus, making connections between space and terrestrial health is encouraged.

Remote environments, such as spaceflight, lack access to fresh foods. Pre-packaged foods are known not to be as healthy as fresh foods that we can get here on Earth. Understanding how to access healthy food in food deserts, a term used on Earth but which applies to remote environments, can lend useful information to how to access healthy food in space.

About the Space Radiation Element
The Space Radiation Element (SRE) is one of five scientific elements of the Human Research Program (HRP) charged with understanding and mitigating the human health risks of spaceflight. Specifically, the mission of SRE is to characterize and facilitate the management of the human health outcomes associated with space radiation exposure to protect astronaut health and wellbeing, as well as enable human space exploration.
 

Connecting SRE to these Topics
Constant exposure the space radiation environment is one of numerous hazards astronauts encounter during spaceflight that impact human health. High priority research topics are related to health outcomes expected to be associated with space radiation exposure including carcinogenesis, cardiovascular disease (CVD), and changes to the central nervous system (CNS) that impact astronaut health and performance. While terrestrial research demonstrates impacts to these systems, little human data exists to robustly characterize these impacts in the space radiation environment. The space radiation environment differs from that present on Earth (e.g. x- and gamma-rays) due to the presence of high-energy particles including protons, heavy ions, and neutrons. Particles produce densely ionizing tracks and impart clustered damage difficult for cells to repair and current animal and cellular research suggests damage induced by particle radiation could increase health effects compared to x- or gamma-rays. Topic areas from the Transnational Research Institute for Space Health are:

Differences in the response to radiation is observed between sexes across a variety of biological outcomes associated with carcinogenesis, cardiovascular disease, and changes to the central nervous system (CNS) that may impact astronaut health and performance. To better characterize the health risks associated with space radiation exposure, it is necessary to explore and define the mechanisms underlying sexual dimorphism following exposure to space radiation.

It is expected that the applicant budget for and plan to attend two (2) workshops or scientific conferences to showcase their work and network with thought leaders within the relevant scientific fields. Specifically, it is expected that the applicant will submit an abstract to the 2024 NASA HRP Investigators’ Workshop which will be held January 29 – February 1, 2024, in Galveston, TX (required), and at least one additional scientific conference relevant to the selected topic. 

Strategies to develop countermeasures against terrestrial radiation exposure typically revolve around agents either that 1) alter the physical interactions of normal tissues to direct exposure (i.e., scavenging the reactive oxygen species generated by the radiolysis of water) or 2) mitigate the downstream biological processes following exposure (i.e., reducing the radiation-induced inflammatory response). Clinical radioprotectors are administered before a planned therapeutic exposure(s) to reduce the likelihood and severity of undesirable side effects. To date, Amifostine is the only FDA-approved radioprotector, but the potential side effects, including severe anaphylactic reactions, reduce the operational utility for spaceflight.  Radiomitigators are given following and unexpected exposure such as a terrorist attack or an accidental occupational exposure. Space radiation exposures differ from terrestrial exposures both in the type of radiation experienced and the rates at which those exposures occur. The quality and dose rate of radiation experienced in the deep space environment present unique challenges in terms of replicating them on the ground, estimating health risks from such exposures and developing strategies to counteract those risks. Traditional in vivo strategies to assess interventional countermeasure efficacy require long-term follow up and large animal cohorts, which limit feasible throughput. Time and resource constraints limit the number of compounds that can be tested using these strategies prior to a Mars mission where the exposure to space radiation exceeds NASA’s permissible exposure limits (PELs). Therefore, strategies that accelerate countermeasure identification, prioritization, and validation need to be developed to improve likelihood of success. New high-throughput screening and informatics technologies to pursue large-scale agnostic countermeasure identification in combination with more targeted, informational approaches represent an attractive comprehensive strategy. These approaches would require the identification of relevant surrogate biomarkers for initiation of long-term health outcomes that could confidently predict disease in models appropriate for this “big science” approach. 

Proposals are sought to identify and/or develop screening techniques to assess compound-based countermeasure efficacy in modulating biological responses to radiation exposure relevant to the high priority health risks of cancer, CVD, and/or CNS. 

Techniques that can be translated into high-throughput screening protocols are highly desired, however high-content protocols will also be considered responsive. Countermeasures and screening techniques focused on acute radiation effects rather than the priority long-term health impacts listed above will not be considered responsive.

Although innate inflammatory immune responses are necessary for survival from infections and injury, dysregulated and persistent inflammation is thought to contribute to the pathogenesis of various acute and chronic conditions in humans, including CVD. A main contributor to the development of inflammatory diseases involves activation of inflammasomes. Recently, inflammasome activation has been increasingly linked to an increased risk and greater severity of CVD. Characterization of the role of inflammasome-mediated pathogenesis of disease after space-like chronic radiation exposure can provide evidence to better quantify space radiation risks as well as identify high value for countermeasure development. 

Proposals are sought to explore and evaluate the role of the inflammasome in the pathogenesis of radiation-associated cardiovascular disease (CVD), carcinogenesis, and/or central nervous system (CNS) changes that impact behavioral and cognitive function.

One of the threats to astronaut health associated with Mars missions is the distance from Earth. Unlike ISS or Lunar missions, the ability to return crew for robust medical treatment is impossible. The capability to assess an astronaut’s individual susceptibility prior to flight, monitor astronaut health in-mission, predict and monitor astronaut health post-flight, and provide an avenue for early detection of high-risk cancers and other degenerative effects like cardiovascular disease or neurodegeneration across astronaut lifespan is important to minimize the long-term health consequences of space radiation exposure and inform standard of care. Therefore, identification and validation of new and emerging biomedical approaches for early detection and treatment of pre-malignant tissues is necessary for the surveillance of astronaut health over their lifetimes (including pre-flight, in-mission, and post-flight) and assessment of risks to long term health pre-flight, in-mission, and post-flight remains a paramount endeavor.

The uncertainties in how low-dose-rate exposures to particle radiation affect the risk of radiation-associated adverse health outcomes are a major contributor to overall uncertainty in risk estimates. Current risk estimates are primarily based on human epidemiological evidence from the Life Span Study (LSS) of atomic bomb survivors who experienced a single, acute dose of radiation composed primarily of γ-rays with a contribution from neutrons. However, astronauts are exposed to a chronic low-dose-rate space radiation environment. Therefore, risk estimates from acute exposures are scaled using a dose and dose-rate effectiveness factor (DDREF) to reflect the chronic nature of space radiation. The current NASA model applies a central estimate for the DDREF of 1.5 to solid cancer risk estimates that was selected based on the BEIR VII report, which assessed terrestrial human epidemiological and animal data. The uncertainty distribution around the central estimate (95% CI: 0.83 to 2.67) is based on terrestrial human epidemiological data, animal data, and cellular data. Both relative increases and decreases in carcinogenesis-related outcomes have been correlated with changes in dose-rate, dependent on examined endpoints, radiation type, and total dose. Additionally, the interaction between radiation quality, total dose and dose-rate has not been fully established. Limited human epidemiological data is available that may provide a more relevant description of the effects of the chronic or protracted low dose-rate exposures in the context of astronaut risk. It is important to note that particle radiation does not deliver dose at a low dose-rate in a conventional (averaged over a volume) context because particles deposit energy as discrete, clustered ionization events, highlighting the importance of micro-dosimetry. Technological limitations in ground-based accelerator design and capability have largely limited the generation of large experimental data sets that address dose-rate effects for particle exposures. Additionally, no data currently exists to provide understanding for the role of dose-rate in a mixed particle radiation field approximating space. Therefore, more data is necessary to characterize the role of dose-rate in radiation carcinogenesis for chronic space radiation exposures. 

Research proposals are sought to identify and/or develop novel in vitro human research models specifically to assess the role of low-dose rate space radiation-like exposure on human cancer risk

Recent findings have shown evidence for structural changes in human brain after long-duration spaceflight (Koppelmans et al. 2016, Van Ombergen et al. 2017, Roberts et al. 2019).  In addition, there are some indications that functional changes are also involved, as revealed by changes in resting-state connectivity. Ground-based research in animal models exposed to accelerated particle radiation has identified synaptic and neurophysiological changes associated with decrements in behavioral performance.  These studies are reviewed in the NASA Evidence Report, Risk of Acute and Late Central Nervous System Effects from Radiation Exposure (https://humanresearchroadmap.nasa.gov/Evidence/other/CNS.pdf) (Nelson et al. 2016), NASA Taskbook (https://taskbook.nasaprs.com/tbp/index.cfm), as well as in a recent review by Kiffer et al. (2019). 

Due to advances in computational power and software used to model neuronal structures of the brain, the Space Radiation Element is interested in accelerating research by utilizing complex, data-driven, 3D model(s) of the dentate gyrus, the hippocampus CA1, or the prefrontal cortex to characterize network level functional changes resulting from radiation-induced perturbations to cell structure and membrane properties in the above mentioned areas.  

This topic seeks proposals that focus on identifying biophysical parameters and structural features that are altered after radiation exposure and to substitute these into computational models in patterns reflecting radiation exposure. 

The model can then be used to interrogate how network activity is altered and its implications on information processing and network stability – i.e.  a perturbation analysis.  Network firing statistics, ability to maintain oscillations, etc. would represent some of the potential outcome measures. Due to high complexity of the research required, we encourage cross-discipline collaboration and multi-disciplinary teams, including but not limited to radiation biologists, radiation physicists, computational modelers, neuroscientists, etc.

Aeronautics Research Mission Directorate (ARMD)

The Aeronautics Research Mission Directorate (ARMD) conducts research that generates concepts, tools, and technologies to enable advances in our Nation’s aviation future. ARMD programs facilitate a safer, more environmentally friendly, and efficient national air transportation system. 

For more than a century, NASA and its predecessor organization – the National Advisory Committee for Aeronautics – has been the global leader in aviation research.

Results achieved by NASA’s aeronautical innovators through the years directly benefits today's air transportation system, the aviation industry, and the passengers and businesses who rely on those advances in flight every day.

As a result, today every U.S. commercial aircraft and U.S. air traffic control tower uses NASA-developed technology to improve efficiency and maintain safety. That’s why we say “NASA is with you when you fly!”

Yet there still is so much more to explore, so much more to learn.

Scientists, engineers, programmers, test pilots, facilities managers, strategic planners, and people with many other skills – the entire NASA ARMD family – are focused on transforming aviation to make it more sustainable and more accessible than ever before.

University Leadership Initiative

University Leadership Initiative (ULI) is a portfolio item in TACP’s University Innovation Project. ULI provides an opportunity for the U.S. university community to receive NASA funding and take the lead in building their own teams and setting their own research agenda with goals that support and complement the ARMD and its Strategic Implementation Plan.

By addressing the most complex challenges associated with NASA Aeronautics research goals,

universities will accelerate progress toward achievement of high impact outcomes while leveraging their capability to bring together the best and brightest minds across many disciplines. In order to transition their research – a key goal for all ULI teams – participants are expected to actively explore transition opportunities and pursue follow-on funding from stakeholders and industrial partners during the course of the award.

Proposing institutions are invited and encouraged to incorporate other colleges or universities, industry members, non-profit organizations, or other U.S.-based entities as team members. Historically Black Colleges and Universities (HBCU) and other minority-serving institutions are strongly encouraged to participate.

An important part of the leadership role assumed by proposing organizations involves including,

nurturing, and fully integrating the capabilities of partner schools that may be less established or have less prior experience working on NASA Aeronautics research projects.

The ULI Strategic Goals are:

  • Make a Difference: Achieving aviation outcomes defined in the ARMD Strategic Implementation. Plan through NASA-complementary research.
  • Transitioning Research: Research results to an appropriate range of stakeholders that lead to a continuation of the research.
  • Developing the Nation’s Future Workforce: Broad opportunities for students at different levels, including graduate students and undergraduates at universities, community colleges and trade schools, to participate in aeronautics research.
  • Promoting Diversity: Greater diversity in aeronautics through increased participation of minority-serving institutions and underrepresented university faculties in ULI activities. ULI is a highly competitive program that encourages domestic small businesses to engage in Federal Research/Research and Development (R/R&amp;D) with the potential for commercialization of promising innovations. Through competitive SBIR and STTR awards-based programs, small businesses are able to explore the technological potential of their innovations. These programs provide the incentive to profit from the commercialization of innovations. 

 

MUREP Planning Grant Priorities for ARMD

The goals of this ARMD section of the planning grant are to:

  • Stimulate creative engagements between MSI researchers and ARMD on areas of mutual interest within the scope of the ARMD Strategic Implementation Plan and its six Strategic Thrusts.
  • Enable viable partnerships for competing in the annual ULI solicitation, specifically Round 8 of ULI that is expected to be released in March 2024.
  • Develop new technologies which support the ARMD mission.

The outcome of successful proposals to the ARMD section of the planning grant activity is to thoroughly prepare MSI teams with action plans to respond to the annual ULI solicitation release, either as leads or as partners.  Round 6 of ULI is on NSPIRES is available as a guide/example of an ULI solicitation.

 

MUREP Planning Grant Topic Areas for ARMD
The range of problems and research solutions is broad. So, proposals shall clearly and concisely describe:

  • Technological innovation being proposed
  • The ARMD Strategic Thrust primarily addressed, and the Outcome addressed (relevance)
  • Assessment of what is innovative or novel in the proposed innovation and how it will contribute to the chosen Strategic Thrust Outcome(s)
  • Research objectives and expected research products
  • Capabilities of the Principal Investigator
  • Key personnel/facilities

Topic areas are ARMD’s six Strategic Thrusts:

Within the United States, NextGen is the focus for a modernized air transportation system that will achieve much greater capacity and operational efficiency while maintaining or improving safety and other performance measures. ARMD will contribute specific research and technology to enable the continued development of NextGen and beyond to achieve safe, scalable, routine, high-tempo airspace access for all users. ARMD also will work with the emerging Urban Air Mobility ecosystem, developing concepts to enable a safe, scalable system for the growth of this new transportation sector. Projected growth in air travel will require a sustained focus on reducing risks to maintain acceptable levels of safety; to that end, ARMD will work with the Federal Aviation Administration (FAA), the Commercial Aviation Safety Team, and others to perform research and contribute technology that addresses current and future safety risks. Similar ongoing international developments, such as the European Union’s Single European Sky Air Traffic Management Research effort, are being globally harmonized through the International Civil Aviation Organization (ICAO).

Development of efficient, cost-effective, and environmentally compatible commercial supersonic transports could be a game changer for transcontinental and intercontinental transportation, providing an opportunity to maintain U.S. leadership in aviation systems and generate economic and societal benefits in a globally linked world. In order to achieve practical and affordable commercial supersonic air travel, ARMD will focus its research on advancing groundbreaking technologies that overcome barriers to reducing its environmental impact and realizing innovative economic efficiencies. Since overcoming these barriers likely will involve modifications to regulations and certification standards for supersonic flight, ARMD will conduct its research in cooperation with the FAA, ICAO, and other aviation regulatory agencies.

Significant improvements in aircraft efficiency, coupled with reductions in noise and harmful emissions are critical to realizing the aviation community’s projections for growth while achieving greatly improved environmental sustainability. ARMD seeks to enable substantial efficiency gains along with a fundamental shift to innovative alternative energy-based propulsion systems through the electrification of aircraft propulsion in combination with sustainable alternative jet fuels and renewable energy. ARMD also is working to enable substantial reductions in time and cost to market of aircraft through advanced materials, structures, and manufacturing technologies and enhanced digitalization of the full aircraft life cycle. ARMD will work across government, the transport industry, and academia to develop critical technologies to enable revolutionary improvements in economics and environmental performance for subsonic transports. ARMD will actively seek opportunities to transition to alternative propulsion and energy for all categories of subsonic transports, including short-haul and regional aircraft as well as large commercial aircraft.

The aviation community expects new and cost-effective uses of aviation including advanced vertical takeoff and landing (VTOL) vehicles that could provide options for using air travel as part of daily activities through unprecedented accessibility and shorter door-to-door travel times compared to other modes of transportation. While this capability is expected to greatly increase the demand for air service and significantly increase the number of flights, this mode of air travel will only be practical if the advanced VTOL aircraft provide acceptable levels of safety while reducing its environmental footprint – especially with regard to noise – compared to existing VTOL aircraft. ARMD will work across government, transport industry, and academia to develop critical technologies to enable realization of extensive use of vertical lift vehicles for transportation services including new missions and markets associated with Urban Air Mobility.

ISSA is a safety net that utilizes system-wide information to provide alerting and mitigation strategies in time to address emerging risks. Moving forward, aviation safety needs to take advantage of modern information availability and intelligent systems. New operational concepts will change and diversify aviation and create the need for advanced safety capabilities that operate on a broad scale. ISSA will incorporate both advanced technologies and collaboration between humans and intelligent agents. ISSA must be both system-wide and distributed. Its vision is to predict, detect, and mitigate emerging safety risks throughout aviation systems and operations.

Ever-increasing levels of automation and autonomy are transforming aviation, and this trend will continue to accelerate. ARMD will lead in the research and development of intelligent machine systems capable of operating in complex environments, including the safe integration of Unmanned Aircraft Systems (UAS) in the National Airspace System (NAS). Complementary methods will provide safety assurance, verification, and validation of these systems. To pave the way for increasingly autonomous airspace and vehicles, ARMD will explore human-machine teaming strategies. Advanced metrics, models, and testbeds will enable the effective evaluation of autonomous systems in both laboratory and operational settings to safely implement autonomy in aviation applications.
