The NASA Lewis Research Center conducts and directs an electric propulsion research and technology program aimed at providing high-performance electric propulsion system options for a broad range of near- and far-term missions. This evolutionary program emphasizes the development of propulsion systems for three classes of missions: (1) near-term auxiliary propulsion applications such as North-South Stationkeeping for next generation communications satellites and orbit maintenance for orbiting platforms such as Space Station Freedom; (2) advanced solar electric propulsion and SP-100-class nuclear electric propulsion (NEP) for earth-space orbit transfer and robotic planetary missions; and (3) very high power systems to support major space missions including the Space Exploration Initiative. To cover widely disparate mission requirements, the program includes research on electrothermal, electrostatic, and electromagnetic systems. This paper provides an overview of the program with a focus on recent progress.
