This paper presents the results of a contamination analysis and computer modeling study performed for the Space Infrared Experiment (SIRE) using the Space Transport System (STS) Shuttle Orbiter as the launch vehicle for the proposed seven-day sortie mission. These results will provide an accurate description of the deposition levels on the telescope primary mirror and of the molecular number column density (NCD) along the telescope line-of-sight. The planned Helium Purge System was assumed not to be operating. The contri-bution to the contamination environment of any cargo element, other than SIRE and its pallet, was not considered in this study. The study considers five potential contamination sources, including the flash evaporator vent effluents and the vernier reaction control system (VCS) engines plume constituents.
