Meet the Winners


The moon has fascinated people from time immemorial. We have all spent nights staring up at the starry sky, looking at the moon in wonder.  For most of us, travel to the moon is out of reach. But now, you have the opportunity to send your tech to the moon!  

NASA’s new lunar exploration program is the Artemis Program.  As human space exploration evolves toward a permanent presence on the lunar surface, In situ Resource Utilization (ISRU) will become increasingly important. Resupply missions are very expensive.  We need to develop practical and affordable ways to identify and use lunar resources, so that our astronaut crews can become more independent of Earth. Future astronauts have to be able to locate and collect lunar resources and then transform them into the essentials for life: breathable air, water for drinking and food production, building materials for shelter, rocket propellants, and more.  Our mission capabilities will rapidly increase when useful products can be created from in-situ resources.

The ability to prospect, map, and characterize these in-situ resources not only increases NASA’s progress towards a sustained presence on the moon, but also could revolutionize mining, purification systems, the pharmaceutical industry, and other commercial industries - much as we realized enormous technological benefits and advances from the Apollo Program. NASA has issued this challenge to the global community to develop miniaturized payloads that can be sent to the moon in the next 1-4 years and bridge lunar strategic knowledge gaps.

Payloads that support prospecting for resources that help support a sustained human presence are highly desirable, in addition to payloads that enable lunar science, demonstrate new technologies and/or advance the use of resources found on the moon (in-situ resource utilization, ISRU). 

Imagine a rover the size of your Roomba® crawling the moon’s surface. These small rovers developed by NASA and commercial partners provide greater mission flexibility and allow NASA to collect key information about the lunar surface. However, existing science payloads are too big, too heavy, and require too much power for these rovers and new, miniaturized payload designs are needed. Payloads need to be similar in size to a new bar of soap to fit cleanly inside the rover (maximum external dimensions: 100mm x 100mm x 50mm).

This ideation challenge will award $160,000 total in prizes across two categories. This ideation challenge is expected to be followed by new challenges to prototype, test, and deliver these miniaturized payloads. This larger effort will generate a maturation pipeline of next-generation instruments, sensors, and experiments that can be used for lunar exploration over the next few years.

The Commercial Lunar Payload Services (CLPS) program supports the Artemis Program through the development and deployment of small robotic landers and rovers.  These new lunar micro-rovers will be launching over the next several years to gather information about and conduct scientific research on the lunar surface. To meet the size, weight, and power constraints of these micro-rovers, new scientific payloads have to be designed, built, and tested in time for the different launch opportunities.

Additionally, NASA would like these next generation payloads to do more than just deploy sensors and collect information about the lunar environment.  Continued advancement of lunar and space exploration requires demonstrations of new technologies that can be employed outside of Earth. Miniaturized payload proposals that actively run relevant experiments, or demonstrate new instrumentation in a lunar environment are highly desirable.  

Although there are already many good ideas for miniaturized payloads, the struggle is to find those good ideas which are readily reduced to practice.  This challenge wants to recognize and reward payload proposals that can demonstrate near-term technical readiness, high impact, and the ability to integrate with micro-rovers.



The timeline for establishing a pipeline of suitable payloads is aggressive.  NASA plans to launch the first of these micro-rovers in 2022. To be successful in this ideation competition, your proposed miniaturized payloads will:

  • Bridge one or more of the highlighted lunar strategic knowledge gaps
  • Have a technology readiness level (TRL) of 3 or greater
  • Be compatible with the new micro-rovers

The full specifications for micro-rover payloads can be found under the Resources tab (Small Lunar Payload User's Guide).  Participants are strongly encouraged to familiarize themselves with the specifications. Payloads do not have to be located on the top of the micro-rover.  Additionally, note that these specifications represent the maximum limits for size, weight, power consumption, etc.  NASA JPL has a strong desire for proposed payloads that are smaller and lighter than the limits described in the payload user’s guide.  Key payload guidance includes:

  • Ability to manage external temperatures ranging from -120° to +100°C
  • Maximum exterior enclosed dimensions of  100mm x 100mm x 50mm
  • Maximum mass of 0.4Kg

There is particular interest in payloads that will help identify and characterize lunar resources, as well as those that will enable ISRU.  The loose, fragmental material on the Moon’s surface is called regolith and is a product of meteoritic bombardment - it is the debris thrown out of the impact craters.  Minable concentrations of resources in the regolith need to be mapped so NASA can select the best locations to send our astronauts. Important resources in the regolith include volatile compounds such as water, CO2, and methane.  They are of special interest because they are essential for life support and can be used for propellant production. Regolith  containing minerals with high concentrations of oxygen, carbon, titanium, and iron are also of interest. Sulfur is important too because it can be used as a binding agent for lunar construction.  Many prospecting technologies for these minerals and elements are successfully used on Earth, but they need to be miniaturized, repackaged, and tailored for use on the Moon. Payloads are needed that can address these broad strategic knowledge gaps:  

  • The lunar resource potential
    • Regolith resources - identification of volatiles, minerals and elements, as well as measurements of their quality, quantity, and distribution
    • Polar Resources - understand the regolith densities with depth, cohesiveness, grain sizes, slopes, and blockiness.
    • ISRU production and/or testing
  • The lunar environment
    • Solar activity - solar event prediction and warning
    • Radiation environment at the lunar surface

As mentioned above, the first CLPS micro-rover is scheduled to launch in 2022, with annual launches thereafter.  The goal of this and subsequent challenges on this topic is to develop a pipeline of ready-for-launch payloads. To help achieve this goal, proposed miniaturized payloads must be at TRL 3 or greater.  For those unfamiliar with the definitions for the different TRLs, a table of definitions is available under the Resources tab (Technology Readiness Level Definitions). The figure below provides a graphical representation of TRLs.

Broadly speaking, TRL 3 is achieved when proof of concept is demonstrated.  By TRL 6, the technology has been reduced to practice with a working prototype.  To ensure that proposed payloads are sufficiently mature, a Payload Specifications and Capabilities form must be completed as part of the submission form.  A view-only version of this form is available under the Resources tab. The ability to thoughtfully and responsively complete this Payload Specifications and Capabilities form is a good indicator that your proposed payload idea is sufficiently mature to fare well in this challenge.



This challenge has a total prize purse of $160,000 that will be divided among a number of winners across 2 different categories.  First prize winners in each category will each be awarded $30,000, second prize winners $15,000, and third prize winners $5000.  

These generous ideation prizes are intended to motivate and reward thoughtful, comprehensive submissions for miniaturized payload proposals that ideally:

  • Demonstrate new technology/instrumentation or run an experiment
  • Explore the lunar resource potential or lunar environment
  • Have a TRL greater than 3
  • Are smaller and/or lighter than the maximum limits described in the specifications guide

Please carefully review the evaluation criteria below to understand what is important to NASA.
