there are about 170 million pieces of space debris orbiting the Earth. Apart from dead satellites, there are also spent rocket boosters and bits of machinery scattered by accidental collisions.And they are not just floating around peacefully — some pieces are moving faster than a bullet. Because they move so fast, even the tiniest piece of cosmic junk poses an enormous threat to other satellites and spacecraft."Imagine how dangerous sailing the high seas would be if all the ships ever lost in history were still drifting on top of the water," said ESA Director General Jan Woerner in the press release. "That is the current situation in orbit, and it cannot be allowed to continue."These collisions are dangerous for manned space flights, but could also impact our daily lives — we rely on satellites for essential information like weather forecasts, communications and GPS.These pieces of debris can take centuries to leave our orbit — if they leave at all. The problem is already so severe that it is self-perpetuating; even if we were to stop all space launches immediately, the amount of junk would continue to grow because existing pieces of debris often collide and break into smaller pieces, 1204
