Aerojet Rocketdyne tapped to build high-power ion drive | Spaceflight Now
Aerojet Rocketdyne has won a $67 million NASA contract to build an advanced electric propulsion system with double the thrust of today’s ion thrusters that could drive future expeditions to asteroids and Mars.
The high-power propulsion system will be based on Hall thrusters, which accelerate xenon gas through an intense electric field to generate thrust with better fuel efficiency than conventional chemical rocket engines.
NASA said work under the Aerojet Rocketdyne contract will lead to a propulsion system could increase fuel efficiency for space missions 10 times over existing chemically-fueled rocket thrusters.
