collisions with the Sun causing solar flares
damage to a spacecraft or the International Space Station
collisions with Mars damaging space probes on that planet
re-entry into Earth’s atmosphere causing craters in Earth’s crust

decreases the telescope’s exposure to damaging electromagnetic radiation in the
atmosphere
