- Abstract
The small debris from orbit is quite complex, including the micro meteor and artificial debris. The small debris with the size in sub-micron level to millimeter level, is neutral or ionized with speed from 0~72km/s relative to the spacecraft. These make sure that the debris will damage the spacecraft in many ways. We use static accelerator to study the accumulation damage to the heat control coat and the accumulation contamination to the optics glasses by large amount debris with the reference from others. We also discuss the possibility of the damage to the exposed high voltage instruments by the discharge which is influenced by the small debris, and all of this is based on the space exposure test and lab simulation test results.
