Phase Four and OrbitFab to Collaborate on in-Orbit Refueling

Companies seek to explore collaboration with RAFTI™ refueling system and Maxwell engines using both traditional and advanced propellants

EL SEGUNDO, Calif., January 24, 2022 (Phase Four PR) –– Phase Four, the creator of the radio-frequency thruster for satellite propulsion, announced today that it has signed a memorandum of understanding with Orbit Fab, the market leader for in-orbit refueling services and the creator of RAFTI, the industry standard satellite refueling interface. The companies seek to ensure that future Phase Four Maxwell engines may be refueled in-orbit to extend mission lifetimes and maximize ROI for spacecraft. The companies will evaluate RAFTI compatibility for refueling of traditional electric propulsion propellants such as xenon as well as advanced propellants such as ASCENT available to Phase Four’s propellant-agnostic core technology – the RF Thruster.
