NASA's Marshall Space Flight Center is seeking information from potential sources for the development and demonstration of active cooling technologies for high-capacity cryocoolers, specifically targeting Technology Readiness Level (TRL)-6 for Liquid Hydrogen (LH2) storage, with scalability for Liquid Oxygen (LOX) and Liquid Methane (LCH4) for future long-duration missions. The initiative aims to ensure the availability of advanced cryocooler technology necessary for Mars human exploration missions, addressing challenges such as heat interception at low temperatures, reliability over extended periods, and efficient power and weight performance. Interested organizations, including small businesses and historically underrepresented institutions, are encouraged to submit capability statements by October 6, 2024, to Bryan Bregard at bryan.c.bregard@nasa.gov, as NASA plans to utilize this information to inform its acquisition strategy for the Cryogenic Fluid Management Portfolio Project.
