Cryogenic fluids (LOX and LH2 in this context) have been used in spaceflight launch vehicles since the Gemini era. During the short duration of a launch, losses of cryogenic fluids due to boil off and leakage have been acceptable trade-offs for mission performance. Using the current state of the art, cryogenic fluid storage in an operational field (in-space propellant depot or tank storage in situ) is limited to several weeks. Future human space missions will have a duration of months to years and will require consumable losses to be minimal during long term in-space transportation, depot storage, and transfer between tanks.
Describe an innovation that can improve the use of cryogenic fluid management (CFM) in support of extended duration human spaceflight. The proposed innovation can be new technology or a novel use of existing technology. This challenge is seeking improvements to materials, manufacturing techniques, processes, or improvements to components or systems involved in CFM.
