The Trouble with Space Junk

220 miles above the Earth on the 12th of March 2009, was a day like any other on the International Space Station, but that was until they received an unusual message stating that they were having a “Red Conjunction”. A Red Conjunction is a warning code that the space station could be hit by some orbital debris. The space station itself was traveling at nearly 8 kilometres per second, the space junk was traveling at the same speed in the opposite direction, if the two were to hit the consequences could be catastrophic.

This type of danger is becoming a more worrying issue as we become more surrounded by hundreds of millions of pieces of junk moving at speeds over 17,000 miles per hours. In this Horizon documentary the true scale of the problem becomes revealed, with first hand accounts from astronauts and experts.
