Description	Aluminized corner-cube polymethylmethacrylate retroreflectors were coated with 92% SiO(x) - 8% fluoropolymer (by volume) and flown on the EURECA spacecraft. The fluoropolymer-filled SiO(x) protective coating was found to be durable to atomic oxygen when exposed in a ground-based plasma asher to an anticipated mission fluence of 2x10(exp 20) atoms/cm(exp 2). Unprotected retroreflector surfaces were found to develop highly diffuse reflectance characteristics, thus inhibiting their use for laser retroreflector purposes. A noncontacting retroreflector optical characterization system was constructed and used to measure the optical retroreflection characteristics of the following retroreflector materials: uncoated unexposed, coated unexposed, both uncoated and coated ground laboratory atomic oxygen exposed, and coated exposed to space atomic oxygen on the EURECA spacecraft. A comparison of the optical characterizations is presented.
