Abstract: | Spacecraft materials will encounter different space environments in space and there are relevance be tween damage mechanism of different space environments on spacecraft materials. In this paper, space environments and their effects on spacecraft materials are introduced firstly, then damage mechanism and their relevance of space environments such as vacuum, temperature, microgravity, plasma, particle radiation, solar electromagnetic irradia tion, space atmospheres, space debris and micrometeoroid, space contamination, spatial dynamics, erosion, space biology, etc, on spacecraft materials are studied. At last, the developing trends and problems of the spacecraft mate rials are commented. |
