"Dust particles with diameters below 100 mu m represent an important part of the space environment. like satellites or spacecrafts, are constantly bombarded with particles of cosmic velocities of 10 km/s and more," researchers in Darmstadt, Germany report.
"These hypervelocity impacts lead to evaporation of a large fraction of these particles and to the formation of craters on the material surfaces which exhibit diameters which are up to one order of magnitude larger than the impinging particles. This results in a remarkable materials degradation of space exposed surfaces which can considerably reduce the life time e.g. of semiconductor panels for the generation ...
