The SEP project is a part of the Technology Demonstration Missions program within NASA’s Space Technology Mission Directorate. NASA Glenn leads the Solar Electric Propulsion project for the agency. Meet Dr. Peter Peterson, an electric propulsion engineer at NASA’s Glenn Research Center.
Solar electric propulsion (SEP) refers to the combination of solar cells and electric thrusters to propel a spacecraft through outer space. This technology has been exploited in a variety of spacecraft designs by the European Space Agency (ESA), the JAXA (Japanese Space Agency), Indian Space Research Organisation (ISRO) and NASA.
The first operational test of an electric propulsion system in space was Glenn’s Space Electric Rocket Test 1, which flew on July 20, 1964. Since then, NASA has increasingly relied on solar electric propulsion for long-duration, deep-space robotic science and exploration missions.
Hundreds of spacecraft across NASA and the commercial sector are already using SEP, typically operating in the 1-10 kilowatt (kW) range. But as NASA prepares to use electric propulsion for more ambitious science and technology missions, and on human missions for the first time, the agency needs to increase the power available.
This prototype demonstrated the technology readiness needed for industry to continue the development of high-power solar electric propulsion into a flight-qualified system. A prototype 13-kilowatt Hall thruster is tested at NASA’s Glenn Research Center in Cleveland.
Electric propulsion research includes unique capabilities in high-power pulse-electric propulsion systems and nuclear fusion propulsion research. Supporting electric propulsion research, Marshall operates a low-thrust vacuum chamber, which also can be used for chemical propulsion research.
