Spacecraft electric propulsion - Wikipedia
Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit. [1]
What is Electric Propulsion? – Space Propulsion Laboratory
Electric propulsion is most useful for systems that are already in space and ones that value saving mass over a short misson duration. Diverging Cusped Field (DCF) thruster test firing in SPL’s Astrovac test facility at MIT.

Dec 7, 2021 · Enables cleaner flight: Electric propulsion provides a 5- to 10-factor reduction in greenhouse gas emissions with current forms of electricity generation and essentially zero emissions with renewable-based electricity.
The Propulsion We’re Supplying, It’s Electrifying - NASA
Oct 22, 2020 · An electric propulsion system uses energy collected by either solar arrays (solar electric propulsion) or a nuclear reactor (nuclear electric propulsion) to generate thrust, eliminating many of the needs and limitations of storing propellants onboard.
spacecraft propulsion. With literally hundreds of electric thrusters now operating in orbit on communications satellites, and ion and Hall thrusters both having been successfully used for primary propulsion in deep-space scientific missions, the future for electric propulsion has arrived.
ESA - What is Electric propulsion? - European Space Agency
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.
