Cryogenic Propellant Storage and Transfer (CPST)

Space Flight Demonstration development has been canceled in favor of a ground test bed development for of passive/active cryogenic propellant storage, transfer, and gauging systems in space for infusion into future extended in-space missions. The Cryogenic Propellant Storage and Transfer project will demonstrate the capability to safely and efficiently store, transfer and measure cryogenic propellants, including liquefied and super-cooled fuels and oxidizers. These advances will lead to development of next-generation space transportation systems capable of managing large propellant volumes over long time periods necessary for deep space travel. NASA's Human Exploration and Operations Mission Directorate is a primary customer and new opportunities will follow for the agency's industry partners. CPST: Key Mission Facts - The Cryogenic Propellant Storage & Transfer mission will demonstrate technologies required for the development of in-space cryogenic systems to support exploration beyond low-Earth orbit. - The mission will support multiple human architecture elements - It is designed to demonstrate long-duration, storage and transfer of cryogenic propellants. - It will demonstrate an accurate and reliable gauging system for tracking stored propellant.

Developing enabling technologies for the use of high-performance propulsion systems for future crewed or un-crewed exploration missions beyond low Earth orbit. The ability to store and transfer cryogenic propellant in space will also enable the reuse of in-space propulsion stages, reducing the number of launches required for future exploration missions.

This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
