Development of the Imaging Spectrometer for Shuttle and space platform applications

The concept of the Imaging Spectrometer is becoming established as a major new thrust in remote sensing of the earth. A future step will be the Shuttle Imaging Spectrometer (SISEX) currently planned for a 1990 flight. This paper describes the current state of development of SISEX, including the development of a modular concept which will allow major elements of SISEX to be used on NASA's Space platform, the Earth Observing System. This modular approach is expected to result in a substantial overall cost saving.
