Aerojet Rocketdyne’s standardized Solar Electric Propulsion (SEP) module will enable and support key elements for NASA’s return to the Moon and eventual missions to Mars, including the ef cient transfer of SEP SOLAR ELECTRIC PROPULSION cargo, habitats and science payloads prior to human arrival. Our module SERVICE MODULE is exible so it can be used for multiple missions—affordably and reliably.

Aerojet Rocketdyne and NASA are working to develop SEP modules built around the next-generation Hall thruster system.
