Part of: Engineering, Construction, and Operations in Space


As one looks forward to mankind's future in space, it becomes obvious that unprecedented amounts of power will be required for the exploration, colonization, and exploitation of space. Power levels required for various applications vary from a few kilowatts (kWe) to 4 or 5 megawatts (MWe) electric. Significant advancements must be made over the present state of space power technology in order to enable or significantly enhance these missions. The purpose of this paper is to discuss the advanced power system technologies being pursued by NASA to fulfill these future needs. Technologies discussed will include photovoltaic, solar dynamic, and nuclear power systems.
