APOLLO FUSION

An ideal propulsion system would have high thrust for missions like orbit raising, phasing, or plane changes, and high specific impulse for years of stationkeeping. This kind of flexibility is now possible in one system with ACE. As an example, a 1000W ACE can be set to provide 120mN of thrust during the orbit raising stage of your mission. Then on command, it can be switched to high efficiency operation with more than 1600 seconds of specific impulse. With this flexibility, ACE provides the best of both worlds.
