ion thruster

Spacecraft electric engine

An ion thruster is a spacecraft propulsion system that generates thrust by accelerating ions through an electric field.

Unlike chemical rockets that burn fuel explosively, ion thrusters produce gentle but continuous acceleration, making them efficient for long-duration space missions: The probe's ion thrusters will operate for years as it travels to the outer planets.
