Almost all space missions require on-board propulsion for a variety of functions. In many cases, on-board propulsion systems are major spacecraft mass drivers impacting both mission cost and performance. Recent trends toward the use of smaller spacecraft and launch vehicles are expected to put further pressure on propulsion system performance. Because of this leverage, NASA's Office of Space Access and Technology (OSAT) sponsors an aggressive program to develop innovative high performance on-board propulsion technologies for both near- and far-term missions. The program addresses the needs of commercial and government space sectors and the applications set considered extends from large geosynchronous communications satellites to the miniature spacecraft planned by NASA's New Millennium program. The on-board program includes electric and chemical propulsion technologies and is committed to carrying new ideas from inception to insertion. An integrated On-Board Power and Propulsion Strategy has been developed to ensure that the pursuit of advanced electric propulsion systems is well coordinated with OSAT's advanced power system development program. All program efforts emphasize both the development of commercial sources of technology and direct interaction with the user community. This paper provides an overview of NASA's On-Board Propulsion program with an emphasis on program directions and recent progress.
