LOXSAT is a NASA funded cryogenic fluid management demonstration satellite mission. Eta Space is building the payload.[1][2]
It is scheduled to launch no earlier than February 2025 on a Rocket Lab Electron launch vehicle.[3]
Mission objectives
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.[4]
