Talk Title: Keeping the House Clean—The Control of Spacecraft Contamination

Abstract: Contamination can degrade the performance of spacecraft systems. Accumulation of particulate and molecular contamination will cause undesired changes in optical, thermal control and guidance systems of spacecraft. These changes include increase in solar absorptance of thermal control surfaces, and the reduction in transmittance or scatter of light in optical systems. Identification of contamination sensitivities and quantification of the allowable contamination levels on these systems is a logical first step. Once identified, plans are implemented to mitigate the effects of contamination and maintain an acceptable level of hardware cleanliness. The controls that are put in place throughout the manufacture, assembly and testing of these spacecraft systems include selection of materials for the hardware design, use of cleanrooms to control the environment, and monitoring of contamination levels. These efforts will help minimize system performance degradation due to contamination and lead to mission success.
