NASA Invites U.S. Innovators to Solve Lunar Recycling Challenges

According to NASA, the agency is currently accepting submissions from U.S. individuals and teams for the second phase of its LunaRecycle Challenge. This initiative seeks innovative solutions for recycling common waste materials that are expected to accumulate during future human missions on the Moon. The challenge targets materials such as fabrics, plastics, foam, and metals, which could arise from various space activities, including habitat construction and operational processes.

The LunaRecycle Challenge, a component of NASA’s Centennial Challenges program, is structured into two distinct rounds: a milestone round and a final round. Submissions for the milestone round are open through January 2026. The agency plans to announce up to 20 finalists from this initial stage in February 2026. These finalists will then proceed to an in-person event in August 2026, where they will demonstrate their prototypes and undergo final judging. A total of $2 million in cash prizes is available for successful solutions across both rounds of Phase 2.

Estimates suggest that a crew of four astronauts could generate over 2,100 kilograms (approximately 4,600 pounds) of single-use waste within a year. This waste stream is anticipated to include items like food packaging, plastic films, foam materials, and clothing. For the LunaRecycle Challenge’s second phase, participants are expected to develop solutions that can manage realistic volumes of trash. Key requirements for these solutions include minimizing the need for resources and crew time, while also operating safely with minimal hazards. While prior participation in Phase 1 of the LunaRecycle Challenge is not a prerequisite for Phase 2, all participants in the current phase are required to build a physical prototype of their proposed recycling system. Additionally, participants have the option to submit a digital twin of their prototype, which could lead to further awards in both the milestone and final judging stages.

The LunaRecycle Challenge is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, with significant contributions from subject matter experts at NASA’s Kennedy Space Center in Florida and NASA’s Ames Research Center in California. NASA collaborates with the University of Alabama College of Engineering for the management of this challenge. Coordination efforts also involve AI SpaceFactory, a past winner of a Centennial Challenge, and Veolia, a company specializing in environmental sustainability. This initiative is part of NASA’s broader effort to foster a sustainable human presence beyond Earth and advance the future of space exploration by developing novel approaches to resource management in extraterrestrial environments.
