Microgravity Multi-Phase Flow Experiment for Suborbital Testing (MFEST) (MFEST)

NASA, the United States Air Force, other government agencies, and commercial and academic groups continue to develop two-phase systems for space applications in numerous areas. For example, JSC specifically is avidly interested in two-phase systems for active thermal control and life support. Other areas of potential for these systems include in-situ resource utilization designs for planetary missions, spacecraft using nuclear-based power generation, propellant transfer, and commercial space processing. The primary objective of MFEST is to conduct a pathfinder, suborbital flight experiment that focuses on two-phase fluid flow and separator operations through a representative launch, suborbital, and entry profile.

This technology will 1) test the two-phase flow system and vortex separation functions of a water purifier for use in zero-gravity, and 2) demonstrate the sustained operation of a two-phase flow system with a passive gas/liquid separator. It is anticipated that it will eventually benefit future NASA missions and perhaps the commercial space industry.

This is a mature technology (TRL 7) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
