Eta Space's Liquid Oxygen Flight Demonstration (LOXSAT), a NASA Tipping Point mission integrated with a Rocket Lab Photon spacecraft bus. During a nine-month mission in low Earth orbit it will demonstrate 11 cryogenic fluid management technologies (reducing boiloff, transferring propellant, maintaining tank pressure and gauging propellant levels) for future in-space propellant depots, informing the design of Eta Space's Cryo-Dock depot.
