Three specific mission applications of advanced electric propulsion systems are discussed and include: the Comet Rendevous Asteroid Flyby (CRAF) science mission, a cargo ferry vehicle for lunar base construction and resupply and a manned mars spacecraft for initial surface exploration. In all three cases electric propulsion is shown to greatly enhance these missions either by increasing payload, lowering the initial spacecraft mass or a combination of the two. Trip times for all but the lunar ferry application are shown to be comparable to using chemical propulsion. The present status and future development goals of the electric propulsion engine technologies to support these mission applications are also discussed.
