Space platforms and meteorological applications

The use of Shuttle launched and tended space platforms (SP) for research and earth observations in LEO are examined. SPs will accommodate instruments for extended time periods, requiring a Shuttle visit for maintenance and package exchange once every six months. Designs have included off-the-shelf hardware to reduce cost, and comprise instruments for studies of cosmic rays, solar physics, materials processing, space plasma physics, and environmental observations. Solar cell power arrays are detailed, along with thermal control, data management, and attitude control subsystems. Meteorological applications are discussed in terms of the Lower Atmospheric Research Satellite (LARS), for research into coupling of radiative, chemical, and dynamical processes, interactions between the earth's surface, boundary layer, and troposphere, and dynamic and energetic relationships between lower atmospheric processes. Flight configurations and add-on concepts for the SP to lead to a manned space station are indicated.
