Space station architectural issues - The view from science

The evolution from current missions in space from Shuttle-directed to space station-directed is projected, with consideration given to space station missions that will affect the station architecture. The Shuttle science mission is basically to support astronomy and astrophysics work into the 1990s, particularly in launching and refurbishing satellites such as the SMM, the Space Telescope, and the Gamma Ray Observatory. Various new observational facilities are being planned and may be carried by the Shuttle for assembly in orbit. The assembly crews could live on a space station if sufficient capabilities and size were built into the station. The construction of large instruments in orbit, instruments that cannot be launched by any current booster, could permit enough data to be gathered to successfully characterize the evolution of the Universe.
