Abstract

The bidirectional reflectance distribution function (BRDF) of both white and black, flown and unflown Space Shuttle thermal protection system tiles has been measured in the 2.0-5.5 micron range. The BRDFs of flown and unflown white tiles were nearly identical, and typical of a good diffuse reflector (with nearly constant BRDF as a function of reflectance angle. The BRDF of the black tile was modified as a result of experiencing Space Shuttle flight; spectral BRDF in this case became a monotonic decreasing function of radiation wavelength.
