The reflectance data and optical properties before and after flight were demonstrated in order to evaluate the long-term durability of the cermet coating in low Earth orbit (LEO). The coating proved to be quite durable over the Materials International Space Station Experiment (MISSE) 6 mission. The optical properties of the titanium aluminum oxide cermet coating were evaluated in the ultraviolet, visible, and near infrared before flight using a Perkin-Elmer Lambda-19 spectrophotometer. The air mass zero solar spectrums was used to convolute the reflectance data into solar absorptance α, and the uncertainty is estimated to be ±0.005. Spectral reflectance data obtained before and after flight revealed essentially no change in the optical properties of solar absorptance and infrared emittance upon low-Earth-orbit exposure, consistent with ground laboratory evaluation of similar cermet coatings.
