NASA’s Robotic Refueling Mission 3 (RRM3) completed an initial set of tool operations designed by the Satellite Servicing Projects Division, making the idea of using water ice, oxygen or methane from other worlds as fuel for spacecraft seem plausible. The ability to store and transfer cryogenic fuels will help enable interstellar voyages in the far future.
Currently, any spacecraft to far away destinations such as the Moon and Mars must carry all of its propellants with it from launch to termination. This requires the spacecraft to c...
