Solar Electric Propulsion

NASA's Solar Electric Propulsion (SEP) project is developing critical technologies to extend the distance and duration of ambitious new exploration and science missions carried out by NASA and its partners. The project aims to demonstrate key technologies necessary for robotic and human exploration-class transportation systems as well as highly efficient orbit transfer capabilities for commercial space operations and science missions.

Two technicians guide an Advanced Electric Propulsion System (AEPS) thruster being lowered by a yellow hoist inside a vacuum chamber at NASA Glenn Research Center. The thruster is secured with yellow lifting straps and positioned on a metal cart with wheels. The technician in the foreground wears a gray shirt and cap, while the other stands across in a green shirt. The chamber’s interior features ribbed walls and dark, curved flooring, with the test setup visible in the background.
