NASA Glenn Research Center engineers developed and tested the CryoFILL system, incorporating a flight-like cryocooler from Creare LLC, to condense and maintain oxygen at cryogenic temperatures below minus 300 degrees Fahrenheit. This technology targets oxygen extracted from lunar water ice deposits, enabling local production of propellant critical for fuel-efficient and extended surface missions.
By liquefying oxygen on-site rather than transporting full fuel loads from Earth, NASA aims to reduce spacecraft launch weight and costs for future Artemis missions and Mars exploration. While the cryocooler shows promise in laboratory testing, operational deployment will require integration with life support and propulsion systems on planetary landers.
