Popis:	§NASA’s Evolutionary Xenon Thruster (NEXT) is designed to address a need for advanced ion propulsion systems on certain future NASA deep space missions. This paper surveys five potential missions that have been identified as being able to take advantage of the unique capabilities of NEXT. A potential Mars Sample return mission is described, and comparison made between a chemical mission and a NEXT based mission. Four possible near term applications to New Frontiers and Discovery class missions are described, and comparisons are made to chemical systems or existing NSTAR ion propulsion system performance. The results show that NEXT has potential performance and cost benefits for missions in the Discovery and New Frontiers classes.
