Image: NASANASA Tests New Refuel Device for Future In-Space Refueling Missions - NASA
• NASA is testing a new refueling device designed to enable in-orbit cryogenic refueling between two spacecraft. • This technology addresses one of the most difficult engineering challenges in spaceflight, as transferring cryogenic fuels in zero gravity has not yet been achieved. • The capability is critical for next-generation deep space exploration, allowing spacecraft to top off fuel tanks in Earth orbit before traveling further into the solar system.
