Popis: A variety of common spacecraft thermal control materials were exposed to a laboratory test designed to simulate the effects of the low-Earth-orbital space-radiation environment. The goal of this test program was to garner performance data on the subject materials, which included two thickness types of old and new rear-surface-silverized fluorinated ethylene propylene Teflon® tape manufactured more than a decade apart, an embossed version of rear-surface-silverized fluorinated ethylene propylene Teflon tape, perforated rear-surface-aluminized Kapton, and a zinc oxide/methyl silicone white paint. In addition to providing high-fidelity data on the end-of-life performance of the materials, the testing revealed that older samples of the rear-surface-silverized fluorinated ethylene propylene Teflon tape showed widely disparate responses and greater solar absorptance increases compared to samples of the same, newly manufactured materials. Samples of the new rear-surface-silverized fluorinated ethylene propylene ...
