Abstract: Space debris population in low Earth orbit has been increasing constantly with the increase in spacecraft missions. Hypervelocity space debris impacts limit the functionality of glass outer surfaces and, in extreme cases, might cause a total loss of a glass. In this work, a laser driven flyer ground simulation system was used to accelerate aluminum flyers to impact on k9 glass material. Damage characteristics, including mechanical damage and contamination generated by impact with a 1 3mm diameter, 3 25 micron thick aluminum particle accelerated to 2 5 km/s, were looked at. OLS3000 laser sacn-confocal microscope, optical microscopy, and spectrophotometer were used to measure the mechanical damage and the loss of solar transmission. Then we will give the rough calculation to the erosion of the 1m2 K9 glass by 1 3 years of impacts. Keyword?space micro-debris; K9 glass; laser driven flyer; cumulative damages
