Electric Propulsion
Electric propulsion is a type of spacecraft engine that uses electrical energy to accelerate a propellant, providing very efficient but low thrust.

TECHNICAL DEFINITION
Electric propulsion is a class of spacecraft propulsion systems that use electrical power to accelerate a propellant (e.g., xenon, argon) to very high exhaust velocities via electromagnetic forces, offering significantly higher specific impulse and fuel efficiency than chemical rockets, primarily used for orbital maneuvering, station-keeping, and deep-space missions requiring low thrust over long durations.
BACKGROUND
An electric vehicle (EV) is a vehicle propelled mostly by electric power. EVs encompass road, rail, boats and submersibles, aircraft and spacecraft.
