From page 1...
... In view of these capabilities and the anticipated national requirement for human presence in space on a long-term basis, the National Aeronautics and Space Administration (NASA) is studying the possibility of developing a manned space station and, in conjunction with the station, one or more unmanned space platforms.
From page 2...
... Satellite remote sensing is a relatively new information source, providing a means to survey and inventory a wide array of earth resources. It provides a capability to monitor changes and, by predictive modeling, to provide a forecast for the future.
From page 3...
... Even in an operational phase, man's ability to identify transient phenomena, to monitor data quality, to adjust instruments rapidly, and to make in-situ decisions on data handling could prove useful. The Earth's Environment Panel addressed four broad applications of remote sensing: upper atmosphere research, global chemical cycles, weather, and climate.
From page 4...
... For example, the $l25 million Seasat oceanographic satellite probably could have been restored to operation if a means had been provided for its retrieval and repair. The Satellite Communications Panel surveyed projected communications services for the period from l990 to 2000 and concluded that a manned space station would offer little benefit during this period.
From page 5...
... Functional capabilities would include repair, servicing, and replacement of expendables for various types of instruments and spacecraft. The System Design Panel recommended that NASA develop design rules for a number of important space station concepts, including system modularity, subsystem interfaces, and technology upgrading.
From page 6...
... The platform should include a variety of sensors to serve the many earth resource, meteorological, and ocean operations communities. We feel that if a space station is developed, its effective utilization will need significant resources beyond those required for the space station alone.
