High thrust ion engine
Did you know?
An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions using electricity. An ion thruster ionizes a neutral gas by extracting some electrons out of atoms, creating a cloud of positive ions. Ion thrusters are categorized as either … See more The first person who wrote a paper introducing the idea publicly was Konstantin Tsiolkovsky in 1911.
