Multiuse Quick Disconnect for Lunar Surface Fluid Transfer Operations

Creare proposes to develop critical sealing technology needed to transfer cryogenic fluids on the lunar surface. We will build on existing technology that has already demonstrated the ability to repeatedly produce excellent seals at cryogenic temperatures over many mate/demate cycles. The sealing technology can be used as part of quick-disconnect couplings that can be easily handled by astronauts or robotic systems. We propose to modify the seal design to accommodate the dusty environment present on the lunar surface. In Phase I we will prove the feasibility of this approach by modifying the seal design and demonstrating performance under conditions that simulate operation on the lunar surface.

NASA can use Creare’s seals for: (1) fluid transfer operations on the lunar surface, (2) fluid transfers between rocket propellant tanks and orbiting fuel depots, and (3) fluid transfers between satellites and refueling spacecraft. The seal will function for any fluid, but is especially attractive because it functions at cryogenic temperatures. The U.S. Department of Energy has established major programs to expand the use of hydrogen for energy transport and storage, and cryogenic liquid hydrogen is an attractive form to transport and distribute hydrogen thanks to its high density. The technology developed in this program can be adapted for use in hydrogen infrastructure facilities, including pumping stations, refrigeration stations, and distribution centers.

This is early/mid-stage (TRL 4) — 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.
