Meet the Winners


The goal of NASA’s Artemis program is to land the first woman and the next man on the surface of the moon in 2024. By the end of the decade, NASA wishes to create a sustainable base camp on the lunar surface which will serve as a hub for scientific research and can also be a base for future exploration of Mars. A critical component of this program's success is the delivery of supplies and systems to the lunar surface and eventually Mars. 

Building a base camp on the moon is no small task! From small scientific instruments to large rovers and habitat modules, the Artemis program will need a robust and reliable cargo-handling system that can effectively operate in the lunar environment and is compatible with a broad array of lunar lander configurations. NASA welcomes ideas that address how to unload payloads from the lunar landers. 

Payloads of varying mass and volume will be sent to the moon in one of several commercial landers and once they arrive at the lunar South Pole,  they need to be unloaded. These landers will range in size depending on the program requirements, so ideally the solution should be flexible enough to handle a variety of payloads being off-loaded from a range of different vehicles. Current Earth-based logistics systems are too massive to easily be packaged and deployed on the lunar surface. This is why we are asking for your help! We are looking for practical and cost-effective solutions to unload payloads to the lunar surface.

Landing on the moon in 2024 and establishing a sustained human presence will be one of the most challenging logistical efforts ever attempted. NASA is excited to get your ideas on systems that will make lunar exploration a reality.

We are going to the moon, to stay. As the future of a lunar outpost unfolds, NASA is teaming up with commercial partners who will supply the landers and capabilities for the delivery of payloads. Most recently, NASA has selected three providers for human landers (HLS) as well as commercial lunar payload service providers (CLPS) for robotically delivering payloads to the lunar surface (learn more about lunar deliveries on Houston we have a Podcast). Once the cargo has landed, they will need a system to unload the payloads from the landers onto the lunar surface. NASA is looking for autonomous or semi-autonomous, scalable systems that can be launched, landed, and deployed without crew set up that could support a wide range of payloads and landers. Ideally the solution would be fully autonomous so it can operate without human interaction for several years; however, ideas that are not fully autonomous are also acceptable if they have the potential to become autonomous. Manual operations in nominal and off-nominal conditions are also desired, but not required.

The images below show examples of the three human landers and are meant to offer further insights into potential height and volume conditions that landers may impose. Future cargo landers are subject to change. 


NASA has selected three American companies – Blue Origin, Dynetics, and SpaceX – to design and develop human landing systems for the Artemis program. With these awards, NASA is on track to land the next astronauts on the lunar surface by 2024, and establish sustainable human exploration of the Moon by the end of the decade.

As Albert Einstein said, “Everything should be made as simple as possible, but no simpler.” Before investing in and building a large-scale logistics infrastructure, NASA wants to engage the community for ideas that provide high reliability. Solutions can be part of the lander, located separately on the lunar surface, or be a combination of approaches. 

The environment on the moon is distinctly different from Earth’s. Among other things, the lunar environment has no atmosphere, broad temperature swings, reduced gravity, abrasive dust, and uneven terrain with potential obstacles.  Proposed ideas should consider how systems would work in such conditions. Also, note that landers must land well away from key infrastructure to reduce the risk of damaging it. 

NASA has developed some concepts and prototype systems for handling cargo from lunar landers. While these systems are effective at some operations, they may not optimize cost, mass and simplicity. Before baselining a large scale system, NASA is seeking ideas from the public to inform the direction of future development. For this challenge, NASA is looking for concepts and innovative approaches that may have been proven in other fields, or are based on sound reasoning and proven methodologies. Such approaches typically have a Technology Readiness Level (TRL) of 3-4; however, solutions with lower TRLs are acceptable. See the Resources tab for complete definitions of TRLs.


The payloads will range in size and shape and can be categorized into three mass classes: <2 metric tons, 2-8 metric tons, and 8-12 metric tons. Ideally, NASA would like solutions that can handle multiple classes of payloads so that the system can be broadly used. Solutions that are able to successfully unload one class are also acceptable. For the purpose of this challenge, these payloads can be considered black boxes so that the focus is on how the design addresses either one or multiple payload classes. The figure below provides examples of possible payloads in the different classes.  A detailed list of specific examples of payloads is available in the Resources Tab.


The individual components of the unloading system you propose are intended to be sent to the moon in a lunar lander and must fit inside the payload fairing of the launch vehicle. It is important to consider how the mass and volume of your system impacts what else can fit inside the payload fairing and how this impacts mission operations. For instance, you could propose an unloading system that takes up most of a lander’s payload mass but could be left on the moon and used for many deliveries. You could also propose an unloading system that takes up only a small portion of the lander’s payload fairing and may be brought on every trip, leaving room for other payloads. 

For the purposes of this challenge, you can broadly assume that the payload fairing can accommodate a total of 3-5 metric tonnes and has a diameter of 5-8 meters. There is potential to have your unloading system shipped on a larger lander if the cost of doing so is justified by the value your system brings. You can learn more about the different launch options and estimated capacities in the SLS (Mission Planner’s Guide) or the guides for commercially available launch vehicles. Optimizing mass and volume for the overall mission in this way will be an important factor of a successful submission. Since launch vehicles also have challenging volume constraints, packaging efficiency of your concept will be very important. As a reminder, mass and volume are related but not always correlated - consider the difference in volume between a kilogram of feathers and a kilogram of lead!

Standardizing interfaces is a priority for NASA when designing a logistics infrastructure on the moon. The Artemis program is an international one, and integration of different elements on the lunar surface requires a variety of compatible mechanical and electrical interfaces. Imagine seamless integration of systems on the Moon. Just like the iPhone or Android phones having the ability to be charged by USB or being made to a certain spec so that they can use a standard phone cover, your ideas should consider how they can efficiently interface with a variety of systems. The types of landers and payloads will vary. For cargo applications, features such as power standards, robotics interfaces, and external mounting interfaces will need to be defined and optimized. Ideas should include suggestions for how these parts of the system can be standardized. This includes not only the unloading system but also ideas on how the lunar payloads can be packaged and configured on a lander to simplify offloading.

Additional capabilities that are desired but not required as part of your submission include:

  • Solutions that have the capability to load payloads for return to Earth
  • Solutions that have the capability of transporting payloads from landers to point of use
  • The system provides an option for the crew to provide override capability

You can assume the following will be provided: 

  • Power for unloading systems from the lander on which they are mounted and/or from a power source/charging station at the Artemis base camp
  • Commanding and telemetry systems to Earth-based ground control
  • Camera systems on the spacecraft and/or lunar surface to provide insight for cargo operations
  • Cargo operations are conducted during illuminated periods at the Artemis Base Camp for remote visibility



This challenge will award up to $25,000 in total prizes to up to 6 teams:

  • One First place winner will be awarded up to $10,000
  • Two Second place winners will each be awarded up to $4500 ($9,000 total for Second place prizes)
  • Three Third place winners will each be awarded up to $2,000 ($6,000 total for Third place prizes)

In addition to the prizes discussed above, winners may also receive the following non-monetary incentives: 

  • An opportunity to meet with NASA engineers to more fully present the concept and answer any questions
  • If available, a conference or virtual event that allows all prize winners to present their ideas to and interact with NASA technical staff (some State Department restrictions may apply)
  • A press release or other publicity by HeroX and/or NASA announcing the winners
  • Wide promotion of the winner on social media channels including Facebook, Twitter, and LinkedIn
  • Participation in a webinar to showcase the winning solutions to the public.

  • Submission deadline: January 19, 2021 @ 5pm ET
  • Judging: January 19 to March 9, 2021
  • Winners Announced: March 16, 2021

1st Place Winner - $10,000 Prize

Lightweight Inflatable Delivery System (LIDS) by Lauren Fell 

LIDS is an innovative, inflatable gantry with a novel rotatable crane, which makes the system compact, lightweight, and highly versatile. This cost-effective delivery system primarily consists of inflatable components, conserving weight and volume, which offers efficient loading capability. Other noteworthy features include an autonomous attachment capability that allows it to attach to a wide range of lander hatch heights, and a rotatable component that acts as a forklift, combined with a built-in winch that allows for both vertical and horizontal movement of payloads.

Lauren Fell is an avid problem solver. She first participated in NASA’s RFID-Enabled Autonomous Logistics Management (REALM) project storyboard challenge in 2017 and was instantly hooked. She won first place in that challenge and has been competing ever since. Fell has a background in psychology and is in the process of completing a Ph.D. on the application of models from quantum physics to the cognitive science of trust. She also teaches decision science as an associate lecturer at the Queensland University of Technology in Brisbane, Australia, and enjoys expanding their repertoire of skills by competing in NASA challenges.


2nd Place Winners - $4,500 Prize

OO.A  - The mOOngoAt by Team FRD

OO.A is an evolution of current Mars rover designs. The OO.A system can operate autonomously or with other systems to deliver a tough, sustainable, and flexible platform for unloading payloads of all sizes. This multifunctional design proposes simple packaging protocols that allows the lander systems to support various types of tasks, such as mining waste management and other operations across the lunar surface.

FRD is a father and son team. The idea was captained and designed by Fenton Robathan and the project was managed by Peter Robathan. The OO.A system was developed at a design studio based in London that focuses on sustainable and automotive aerospace projects.


Scalable Payload Delivery System (SPaDes) by Team SPaDes 

SPaDeS is based on the idea of expanding infrastructure. The design uses a small rover crane for small and medium-sized payloads, and larger payloads are handled with a crane that uses inflatable structures and lunar material. The whole system is designed to provide maximum usability and flexibility in the harsh lunar environment while optimizing structural solutions to keep the mass and volume of the system economical.

SPaDeS is a multifaceted team with expertise in mechanical engineering, design, and simulation that has come together to create new and innovative solutions, integrating both old and new technologies. Their solutions are created using open-source software, which demonstrates the overall spirit and vision of the team.


3rd Place Winners - $2,000 Prize

Lunar- Transporter and Gantry (L-TAG) by Team AA-Star 

The L-TAG operates in two phases. In the first phase, an inflatable gantry crane deploys to unload the payload. In the second phase, the transporter vehicle is responsible for carrying the payload to the lunar base, which can travel at a speed of 200 meters per hour on rugged lunar terrain. The crane and vehicle can move a mass of 12 metric tons, which is important when considering larger payloads, such as hardware needed to build lunar habitats. A deployable shield around the vehicle protects the payload from lunar dust and micro-meteoroid impacts.

Team AA-Star consists of an interdisciplinary collaboration with expertise in machine design, electro-mechanical and computer science combined with commercial experience. Surya Narayana Murthy Pappala, the team captain, has a master’s degree in information technology with 12 years of experience and is passionate about problem-solving and optimization. Amareswara Pasad Chunduru has a degree in computer applications and expertise in electro-mechanical engineering and is passionate about non-linear dynamics, machine design, and metaheuristics. Sai Ashish Kumar Karanam has a master’s degree in machine design as well as commercial experience and is passionate about product life cycle management, industrial robotics, and Internet of Things devices.


Modular Lunar Cargo Handling System by Team Sparkletron 

The Modular Lunar Cargo Handling System consists of function-specific modules that can robustly manage complex challenges on unpredictable terrain over a range of temperature conditions. Cable-tensed structures and thin-film based electrostatic adhesion surfaces offer high strength-to-weight ratio, lowering costs and enabling unit redundancy. Palletized cargo is manipulated by replaceable, damage-tolerant couplings steered by machine vision, increasing mission success probability. Complex autonomous behavior is enabled by combining simple error-correcting interfaces between subsystems.

Team Sparkletron is an innovative technology team that uses combinations of proven techniques and principles to achieve new goals. Team Captain, Kenji Larsen, is a prototyping engineer. Other team members include daughters Emily, age 6, and Natalie, age 8, who played an integral part in the design process, learning critical decision-making skills and developing optimizations based on practical methods.


Truss Manipulator by Wendell Chun 

The Truss Manipulator is a multi-purpose solution that starts as a lander leg truss structure that is repurposed to a manipulator that can take advantage of the lower lunar gravity to move objects around. This “truss-like manipulator” is needed for landing as part of a structural compression element integrated into the lander’s leg assembly, so it does not take up additional payload space. Once landed, the arm will unlatch from the primary lander leg and is free to travel about the lander.

Professor Chun is the faculty director of systems engineering at the University of Denver. He is a former aerospace principal investigator for Lockheed Martin Corporation and has worked in robotics since the 1980s, with artificial intelligence systems and robotic manipulation systems, including self-driving vehicles. Professor Chun specializes in multi-disciplinary engineering design to address complex problems.
