Interesting Fact - Space

According to a Pentagon report, there is so much junk whizzing around Earth that any collision in space could now cause a knock-on effect that would destroy vital satellites.

(A crash between a satellite and a hunk of space junk could send thousands of pieces of debris spinning around, which could destroy other satellites. This was illustrated in a major crash in 2009 between a U.S. communications satellite and a defunct Russian military probe over Siberia. That one collision at speeds of at least 15,000mph created a cloud of 1,500 pieces of space junk, and a Chinese missile test in 2007 left 150,000 pieces of junk in the atmosphere.

The latest efforts being made up there include two spacecraft that are about to begin an unusual waltz above the Pacific Ocean to try to evade interference from a third, failed satellite; Intelsat's Galaxy-15 platform in April.)
