Low Leakage Cryogenic Disconnects for Fuel Transfer and Long-Term Storage

To enable deep space missions, the capability to transfer and store cryogenic fuels (typically liquid hydrogen, methane, and oxygen) without significant leakage over long duration missions is critical. NASA has been actively developing zero boil-off cryocooler technology to reduce storage losses. Another source of fuel loss is from leakage at the fuel disconnect used for in-space refueling.
