Abstract : The purpose of the program was to develop improved pigmented polymeric and inorganic coatings having low solar absorptance and high emittance and improved stability to 'space' radiation effects (vacuum, ultraviolet, and particulate radiation) for use in the passive thermal control of spacecraft. Efforts were undertaken to investigate the radiation stability of selected rare earth oxide pigments and pigmented silicone and silicate coatings to a laboratory simulated space environment. Environmental tests of silicone and silicate formulations included exposure to vacuum-ultraviolet, vacuum-electrons, and vacuum-ultraviolet-electrons with both in situ and non-in situ optical reflectance measurements being taken.
