Available in PDF, EPUB and Kindle. Book excerpt: The ML12 experiment was launched 30 Jan 79, on the USAF Space Test Program P78-2 spacecraft, sometimes called SCATHA. It was designed to determine if spacecraft charging contributes significantly to the rate that contaminants arrive at exterior spacecraft surfaces, and to establish some of the characteristics and effects of these contaminants. Two sensor types are used in the experiment: (1) A combination retarding potential analyzer (RPA) and temperature controlled quartz crystal microbalance (TOCM). With it, distinction can be made between charged and uncharged arriving molecules, and information can be obtained concerning the temperature dependence of contaminant adsorption and desorption rates. (2) A tray of calorimetrically mounted thermal control coating (TCC) samples. Samples of different spacecraft surface materials are exposed to arriving contaminants, and the solar absorptances sa of these materials are continuously measured. The two RPA/TQCMs are both accumulating mass but the accumulation rates and characteristics of the mass differ. Ultraviolet from the sun is the likely reason. Non-line-of-sight contamination transport has been found to be important at geosynchronous altitudes. With one exception, the early orbital values of sa are in good agreement with prelaunch values indicating little contamination during prelaunch activities. The very small change in sa for an optical solar reflector and other space-stable samples indicates that the SCATHA spacecraft was exceptionally clean. As a result, large sa changes for other TCCs are attributed to the effects of radiation damage.

Available in PDF, EPUB and Kindle. Book excerpt: This Tutorial Text provides a comprehensive introduction to the subject of contamination control, with specific applications to the aerospace industry. The author draws upon his many years as a practicing contamination control engineer, researcher, and teacher. The book examines methods to quantify the cleanliness level required by various contamination-sensitive surfaces and to predict the end-of-life contamination level for those surfaces, and it identifies contamination control techniques required to ensure mission success.

This book was released on 2018-07-24 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents analyzed surface areas on particular experiment trays from the Long Duration Exposure Facility (LDEF) for silicone-based molecular contamination. The trays for examination were part of the Ultra-Heavy Cosmic Ray Experiment (UHCRE). These particular trays were chosen because each tray was identical to the others in construction, and the materials on each tray were well known, documented, and characterized. In particular, a known specific source of silicone contamination was present on each tray. Only the exposure conditions varied from tray to tray. The results of post-flight analyses of surfaces of three trays were compared with the predictions of the three different spacecraft molecular contamination models. Phase one tasks included: 1) documenting the detailed geometry of the hardware; 2) determining essential properties of the anodized aluminum, Velcro(Tm), silverized Teflon(Tm), silicone gaskets, and DC6-1104(Tm) silicone adhesive materials used to make the trays, tray covers, and thermal control blankets; 3) selecting and removing areas from each tray; and 4) beginning surface analysis of the selected tray walls. Phase two tasks included: 1) completion of surface analysis measurements of the selected tray surface, 2) obtaining auger depth profiles at selected locations, and 3) running versions of the ISEM, MOFLUX, and PLIMP (Plume Impingement) contamination prediction models and making comparisons with experimental results.
