Propulsion for the Deep Space One (DS1) spacecraft is provided by a xenon ion engine. Xenon is stored in a supercritical state and is delivered as a low pressure gas to the thruster and two cathodes by a Xenon Feed System (XFS).

Propulsion for the Deep Space One (DS1) spacecraft is provided by a xenon ion engine. Xenon is stored in a supercritical state and is delivered as a low pressure gas to the thruster and two cathodes (called the main cathode and neutralizer) by a Xenon Feed System (XFS).
Various methods of significantly reducing the mass of planetary spacecraft propulsion systems were addressed. Because of the Space Shuttle Challenger accident, the availability of the Space Transportation System for planetary missions may be limited. Mounting a future planetary mission with lower-energy launch vehicles will require a significant reduction in the spacecraft mass. Smaller launch vehicles for planetary missions were considered. In this study, the assumed payload capability for the planetary missions were considered. In this study, the assumed payload capability for the planetary missions was restricted to the Delta and the Atlas-Centaur launch vehicles. Several propulsion and propulsion-related technologies for spacecraft mass reduction were investigated; ion, arcjet, resistojet, and Magneto-Plasma-Dynamic propulsion and earth-storable high-energy propulsion system thrusters were candidates. The propulsion-related technologies included a start-basket Propellant Management Device, a nitrogen tetroxide diaphragm, and a solid-cryogen cooler. Xenon-ion propulsion allowed the greatest mass reduction.
