30 September 2013 Optical test results of carbon composite mirrors from MISSE 7A
Author Affiliations +
We report on the optical performance of carbon fiber reinforced polymer composite (CFRP) mirrors after 1.49 years exposure onboard the Materials International Space Station Experiment (MISSE 7). Mirror samples were placed on the MISSE 7A tray, outside the ISS from October 2009 and retrieved September 2011. The environment was an extreme environment exposure test, which is considered “worst case” for survivability of composite mirrors for imaging applications in low-earth orbit (LEO) The results from testing the returned flight samples show degradation in two of the mirror’s aluminum coatings. However, the surface figure of one of the coated mirrors remained largely unchanged after the long-duration experiment. Test results will be compared against the original, pre-flight mirror performance for each of the 3 samples.
