Last week, the International Space Station (ISS) was forced to maneuver out of the way of a potential collision with space junk. With a crew of astronauts and cosmonauts on board, this required an urgent change of orbit on November 11.
Over the station's 23-year orbital lifetime, there have been about 30 close encounters with orbital debris requiring evasive action. Three of these near-misses occurred in 2020. In May this year there was a hit: a tiny piece of space junk punched a 5mm hole in the ISS's Canadian-built robot arm.
Last week's incident involved a piece of debris from the defunct Fengyun-1C weather satellite, destroyed in 2007 by
a Chinese anti-satellite missile test. The satellite exploded into more than 3,500 pieces of debris, most of which are still orbiting. Many have now fallen into the ISS's orbital region.
