Space electric propulsion is a key in-space propulsion technology that enables highly fuel-efficient space missions. By using electrical energy to ionize and accelerate propellant, electric propulsion systems significantly reduce the amount of fuel required compared to traditional chemical propulsion.
Electric propulsion has been increasingly adopted for a wide range of space missions, including low Earth orbit and geostationary Earth orbit satellites, as well as missions to asteroids, the Moon, and comets. With the growing number of space missions relying on electric propulsion, continued research and development are essential to further enhance its performance and expand its role in future advanced space exploration.
