Artist's Concept of a Solar Electric Propulsion System
Using advanced SEP technologies is an essential part of future missions into deep space with larger payloads. The use of robotics and advanced SEP technologies like this concept of an SEP-based spacecraft during NASA mission to find, rendezvous, capture and relocate an asteroid to a stable point in the lunar vicinity offers more mission flexibility than would be possible if a crewed mission went all the way to the asteroid.
