Integrated requirements for a space station

The time-phased mission set developed for the proposed space station program (including the manned facility, coorbiting and remote free flyers and platforms, orbital maneuvering and transfer systems, and storage and service facilities) by the Space Station Mission Requirements Workshop in May 1983, is presented in figures and tables and discussed. The scientific, commercial, and technology-development proposals are characterized, and the requirements for a station and coorbiting platform at 28.5-deg orbital inclination are listed for the period 1991-2000. Japanese, ESA, and Canadian utilization is considered, special requirements are outlined, and functional characteristics are summarized. Developmental strategies to meet the concerns of the user community are suggested.
