Ion Thruster

An ion thruster is a type of spacecraft propulsion system that uses electricity to accelerate ions (charged particles) for thrust. Unlike traditional rockets that burn fuel, ion thrusters create an electric field to ionize a gas, then expel the ions at high speed. This produces a gentle but efficient forward push. While ion thrusters generate less thrust than conventional engines, they can operate for long periods, making them ideal for deep space missions, where fuel efficiency is crucial. Their ability to work in the vacuum of space allows spacecraft to travel farther and faster over time.
