【Abstract】 The definition, sources and distribution of the space dust particles, as well as the probability for the dust particles to collide with external materials on spacecraft, were expounded. The research state on effects of space dust environment on thermal materials, solar cells and multi - layer insulation blankets was described in terms of the interaction of space dust environment with materials. The ground - based simulation tests demonstrated that the space dust collision could result in the damage of the above materials and elements to different extent.更多还原
