Advances in space power research and technology at the National Aeronautics and Space Administration

The mission of the National Aeronautics and Space Administration's Space Research and Technology Program is to provide a technology base that will adequately support, enhance, or enable current and future activities in the exploration and exploitation of space. This paper summarizes the current status, accomplishments, and goals in the power-system-component areas of photovoltaics, electrochemistry, thermal-to-electric conversion technology, and power management.
