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.
