Orbit Fab and Phase Four sign in-orbit refueling memorandum
Orbit Fab and Phase Four signed a memorandum of understanding to evaluate RAFTI refueling compatibility with Phase Four Maxwell electric thrusters.
Evidence notes
- The companies will evaluate refueling with xenon and the advanced propellant ASCENT.
- The work pairs Orbit Fab's RAFTI interface with Phase Four's propellant-agnostic RF Thruster architecture.
- The memorandum is intended to give future Maxwell customers an option to extend mission life through on-orbit refueling.
Company context
