Electrically powered spacecraft propulsion

6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory.

An electrically powered spacecraft propulsion system uses electrical energy to change the velocity of a spacecraft. Most of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed, but electrodynamic tethers work by interacting with a planet's magnetic field.
