Futuristic spacecraft thruster would use 100 million times less fuel than a conventional rocket

Hall thrusters are advanced electric rocket engines primarily used for station-keeping and attitude control of geosynchronous communication satellites and space probes. Recently, the launch of two satellites based on an all-electric bus has marked the debut of a new era – one in which Hall thrusters could be used not just to adjust orbits, but to power the voyage as well. Consuming 100 million times less propellant or fuels than conventional chemical rockets, a Hall thruster is an attractive candidate for exploring Mars, asteroids and the edge of the solar system.
