Surface Effects of Satellite Outgassing Products
Abstract
The program will measure optical and radiative effects of satellite material outgassing products on thermal control and cryo-optic surfaces. Two systems were required for making the measurements, (1) an optical properties chamber for measuring the optical properties such as the complex refractive indices and bidirectional reflectance distribution function (BRDF) of condensed contaminants on cryo-optic surfaces, and (2) a solar absorptance chamber for making reflectance/absorptance measurements on thermal-control materials. This report identifies and describes the operation of these systems and presents optical property data for condensed contaminants on cryogenic surfaces. Refractive and absorptive index data are presented for the adhesives DC93-500, DC6-1104, RTV566, RTV-732 Silastic, for Kapton film, and S13G/LO paint. This program is continuing and properties for other materials will be available in the future. Measurements of BRDF data on contaminated cryogenic optical components and solar absorptance data on contaminated thermal-control surfaces will be made.
