Shuttle/Payload Contamination Evaluation (SPACE) Program Verification With The Induced Environment Contamination Monitor

The ultimate test of the validity of the Martin Marietta Aerospace Shuttle/Payload Contamination Evaluation Computer Program utilized to analyze the induced optical environment of sensitive instruments and systems will be through comparison of model predictions with acquired flight data. A prime opportunity will occur during the early Shuttle and Spacelab missions which will carry the Induced Environment Contamination Monitor (IECM) package. This paper presents the applicable IECM instrument descriptions, an assessment of the applicable IECM parametric measurements and a synopsis of the systematic approach to be employed in verifying the computer model methodology and the significant influencing model parameters.
