Paper Abstract

EOS AM-1 is the first in the series of the EOS spacecraft developed to advance the understanding of the biological and geophysical processes of the Earth's climate on a global basis. The fully integrated spacecraft is EOS AM-1 flight- phase contamination analysis has been performed to verify that the design of the spacecraft is compatible with limiting contamination to the level required for optical instruments and sensor, thermal control surfaces and solar array as well as to identify modifications if needed. This paper summarizes the approach and assumptions used in performing this contamination source and effects analysis for the EOS AM-1 spacecraft. Molecular and particulate contamination potential during the flight segment from launch through completion of orbital mission has been analyzed. Potential contamination sources examined include materials outgassing, instrument and spacecraft bus venting, spacecraft plume and other sources such as mechanisms, moisture absorption, and atomic oxygen. The modeling result have been used to confirm outgassing materials selection, to verify venting designs, and to develop bakeout requirements for components of the spacecraft bus and the instruments.
