This paper presents the analysis of the nature, the source, and the effect of contamination encountered by payloads external to the Space Station spacecraft. The contaminant modeling study determined the key contaminant sources for the Space Station payloads, together with the location, the duration, the major constituents of the contaminant, and the possibility of contaminant control. The next phase of the contamination modeling study investigates the compatibility of external Space Station payloads while on the transverse boom and the dual keel option. Other predictions include depositions on payload surfaces facing along +X, +Y, and +Z directions. An additional analysis will utilize the above data to predict the spectral brightness of the contaminants along payload lines-of-sight, making it possible for payload users to determine the impact of the contaminant background relative to the natural background.
