The stability problem of operational characteristics of external materials in space vehicles is very important for spacecraft development with life span period of 20 years and more. Without the assessment of space factors’ effects on the properties of optical and thermo regulating covers, films and composite materials, special‐purpose fabrics and other materials used in long‐term missions, it is impossible to design adequately the satellites, interplanetary vehicles and orbital stations able to withstand such long‐term missions.
This paper is an attempt to review the results of materials’ tests carried on detachable cassettes and placed on Salyut, MIR and ISS orbital stations in the period 1990–2008. In all experiments, the samples underwent long‐term exposure in outer space.
The numerous material samples selected for investigations were installed on the external surfaces of the Space Stations Salyut and MIR and on the Russian segment of International Space Station as removable cassettes of FM‐110 FM‐111 and SKK types. The major properties of all samples including the thermo‐optical, mass, structural and other physical and chemical characteristics were evaluated before and after the space exposure. The test results of optical and thermo‐regulating covers and composite and film materials and other materials under long space exposure conditions (up to 1638 days) are presented in the report.
