Paper Abstract

Degradation of sensitive satellite surface scan adversely effect the accuracy, lifetime and mission effectiveness of a spacecraft or payload. More sophisticated and complex space systems have increased the concern about contamination. Thus, it has become necessary to develop better prediction tools and testing techniques for use in contamination prevention and control. This paper discusses the effect of the induced contamination environment on the long-term degradation of two remote sensing instruments. Both instruments were the subject of contamination control programs. The Stratospheric Aerosol Gas Experiment (SAGE II) was launched by the shuttle on the Earth Resources Budget Satellite in 1984. The result of a throughput degradation contamination assessment performed prior to launched compares actual results acquired through March, 1998. The SAGE II instrument still continues to produce data within the limits predicted. A Total Ozone Mapping Spectrometer was launched in 1991 on a Russian Meteor-3 spacecraft. Degradation of the solar calibration diffuser plates have been observed and reported earlier. A new instrument, SAGE II, will be launched in 1999 on another METEOR-3 spacecraft from the Baikonur Cosmodrome in Kazakhstan. The METEOR- 3M/SAGE III is currently undergoing an intense contamination control program in order that data of the same quality as the SAGE II instrument will be realized.
