Space Station Freedom as an earth observing platform

The Space Station manned base is discussed, focusing on the use of the base as a science platform for earth observation. The program elements of the Space Station are described, including the manned base, the international elements, the Polar Platform, and the Man-tended Frequent Flyer. The accommodation and operational requirements for the earth observation payloads are examined. Candidate missions for the manned base earth observation program are presented, including observations of tropical regions, the Tropical Rainfall Measuring Mission, the tropical regions imaging spectrometer, the Earth Radiation Budget Experiment, and commercial remote sensing.
