Working Papers: Electric Propulsion Technology Overview

Efforts in the realm of electric propulsion have been both steady and cutting-edge. Past, present, and future projects are discussed along with both realized and potential mission benefits arising from this recent technology.

Electric Propulsion (EP) is a class of space propulsion, which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters. Unlike chemical systems, electric propulsion requires very little mass to accelerate a spacecraft.
