Space Environment Simulation to Test Satellite Thermal Control Coatings. Volume 2, Appendix 1: Detailed Results of Optical Measurements Made after the Various Stages of the First Test

摘要

Simultaneous irradiation of satellite thermal control coatings by electrons, protons, and ultraviolet radiation, simulating 5 yr in geostationary orbit, was carried out. A layer of contaminant, originating from adhesive RTV566 by molecular flux, was applied to samples under controlled conditions. Changes were followed by microbalances and by measurements of optical reflectance over the spectrum. Results for optical measurements before deposition and for 0.2, 0.5, and 1 yr after are presented.
