The Liquid Oxygen Flight Demonstration, or LOXSAT, will test cryogenic fluid management technologies necessary for creating in-space propellant depots, essentially gas stations in space, that could support long-term exploration.The LOXSAT payload is displayed inside Rocket Lab’s Spacecraft Production Complex in Long Beach, California. Rocket LabDuring a nine-month mission, LOXSAT will demonstrate 11 cryogenic fluid management technologies. Eta Space built LOXSAT as part of a NASA Tipping Point opportunity, and Rocket Lab is providing spacecraft and launch services to deliver it to low Earth orbit. The LOXSAT payload has been integrated with a Rocket Lab Photon satellite bus and will launch aboard the company’s Electron rocket from Launch Complex 1 on New Zealand’s Mahia Peninsula no earlier than July 17.The technologies that LOXSAT will demonstrate were selected to address the core challenges of using cryogenic, or super-cold, propellants in microgravity, including reducing boiloff, transferring propellant, maintaining tank pressure, and gauging propellant levels. Data collected from these tests will support development of future in-space propellant depots that could refuel spacecraft as they journey to the Moon, Mars, or other deep space destinations.Members of NASA’s Cryogenic Fluid Management project tour Rocket Lab’s Spacecraft Production Complex in Long Beach, California, on Thursday, Feb. 12, 2026 .

The cryogenic portfolio’s work is part of NASA’s Space Technology Mission Directorate and includes more than 20 individual technology development activities.To learn more, visit:https://go.nasa.gov/49nbAO5ShareDetailsLast UpdatedMay 14, 2026EditorLee MohonContactJoel Wallacejoel.w.wallace@nasa.govLocationMarshall Space Flight CenterRelated TermsCryogenic Fluid Management (CFM)Marshall Space Flight CenterSpace Technology Mission DirectorateTechnology Demonstration Missions ProgramExplore More3 min readIce to Fuel: NASA Tests Technology for Refueling Landers Article2 months ago4 min readStay Cool: NASA Tests Innovative Technique for Super Cold Fuel StorageArticle10 months ago3 min readNASA Propellant Tech Could Fuel Long-Duration Missions Article1 year agoKeep ExploringDiscover Related TopicsMissionsHumans in SpaceClimate ChangeSolar System
