Today, some 18,000 man-made objects large enough to be tracked circle the Earth, with most of them defunct. Efforts are now under way to develop the means to clean up some of the space junk left in orbit. The urgency of the problem was highlighted in 2009 when a defunct Russian and a working American satellite obliterated each other when they collided at a combined speed of some 42,000 kilometers per hour.
