NASA, Industry Prepare Cryogenic Fuel Technology Demo

NASA is collaborating with Eta Space of Rockledge, Florida, on an in‑orbit technology demonstration to advance a key capability for future deep space missions. 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. During 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. …
