WebIn spaceflight, an ion thruster or drive is a form of electric propulsion used by spacecraft in the vacuum of Space. It works by creating positively charged atoms or ions, which are accelerated at very high velocities through electrically charged grids at the back of the engine to produce thrust. Web3 dec. 2024 · Ion Propulsion System. Dawn's futuristic, hyper-efficient ion propulsion system allows Dawn to go into orbit around two different solar system bodies, ... The thrusters work by using an electrical charge to accelerate ions from xenon fuel to a speed 7-10 times that of chemical engines.
