Space environment simulation to test satellite thermal control coatings. Volume 2: Annex 1

Optical properties measured in situ at -35C and at various exposure stages up to one year are tabulated for thermal control coatings tested during space environment simulation. Results show: (1) spectral reflectance for 13 wavelengths; (2) variation with respect to the initial measurement, i.e., before irradiation and deposition; (3) solar reflectance including ultraviolet, visible, and infrared radiation, as well as the total spectrum (295 to 4,000 nm); (4) variations of solar reflectance with respect to initial values; (5) solar absorptance (calculated as a complement at 1.00 of solar reflectance in the same wavelength domain); and (6) variations of these solar reflectances with respect to initial values.
