LOXSAT is a NASA funded cryogenic fluid management demonstration satellite mission. Eta Space is building the payload. [1] [2] LOXSAT aims to demonstrate on-orbit docking and cryogenic refueling operations using a cryogenic fluid transfer disconnect and latching mechanism developed for depot applications. It will also demonstrate repeated mating/de-mating and the transfer of liquid oxygen. [3] [4] LOXSAT1 will test technology for Eta's orbital depot "CryoDock". [5] It is scheduled to launch no earlier than early 2026 on a Rocket Lab Electron launch vehicle. [6] [7] The follow-up LOXSAT2 mission, a full-scale operational depot, is being defined. [2]
