Analysis of Materials’ Specimens After Long-Term Exposure on ISS Surface in Komplast Experiment

The article presents the first results obtained from the unique long-duration exposure experiment (12 years) on board of the International Space Station (ISS). The Komplast materials experiment was designed by the Khrunichev State Research and Production Space Center, together with other Russian scientific centers, and has been carried out since 1998. Eight Komplast panels with material samples and temperature sensors were located on the external surface of ISS Functional Cargo Block (FGB) module. In March 2011 two of eight panels were returned from ISS by Space Shuttle “Discovery”. Post-flight investigations of specimens were carried out at Skobeltsyn Institute of Nuclear Physics, Lomonosov Moscow State University (SINP MSU) and at other Russian scientific institutes.
