| Abstract: | Stability of materials in low Earth orbit environment (LEO) is one of the most important factors that were concerned for the selection of spacecraft materials.The effects of LEO environment,including those of atomic oxygen,space radiation,thermal cycling,vacuum,micrometeroids and space debris on materials are described.Future research directions,such as ground based simulation tests,development of materials and protective coatings are presented. |
