Space Station power system options

This paper outlines the strategies, reasoning, and planning guidelines used in the development of the United States Space Station Program. The power required to support Space Station missions and housekeeping loads is a key driver in overall Space Station design. Conversely, Space Station requirements drive the power technology. Various power system technology options are discussed. The mission analysis studies resulting in the required Space Station capabilities are also discussed. An example of Space Station functions and a concept to provide them is presented. The weight, area, payload and altitude requirements on drag and mass requirements are described in this paper with a summary and status of key power systems technology requirements and issues.
