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
cargo, habitats and science payloads prior to human arrival. Our 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 thenext-generation Hall thruster system.
Aerojet Rocketdyne
150 kW EP System
PROVEN SEP INTEGRATIONAerojet Rocketdyne has the experience to design and develop a standardized SEP module needed for the Journey to Mars. We are a leader in building and integrating complex power and propulsion systems, including:
• International Space Station 100 kW power system (4x greater than any commercial satellite)• Power systems on Mars robotic missions• Electric propulsion on >150 satellites in orbit• XR-5 – highest power hall thruster ever �own• >250 propulsion systems �own, including those on NASA’s New Horizons spacecraft
SEP/SPACECRAFT INTERACTIONSAerojet Rocketdyne has the expertise and �ight-proven experience to understand and address the complex interac-tions between the solar arrays, electrical power and various subsystems of SEP spacecraft.
We continue to work with other industry leaders to re�ne our knowledge of these complex interactions so that future high-power SEP modules can be as ubiquitous as on today’s satellites.
