space crap
In earths orbit there is a lot of space junk, from old Apollo space craft, to derelict satellites. ... This space junk interferes with some satellite and space shuttle missions, and could collide with other space craft, causing an explosion and putting more space junk into our orbit, to make another explosion. The space junk could end up costing humans millions of dollars. Some of the pieces of space junk orbit earth at 17,500 mph! In 1999 a study estimated some 4 million pounds in low earth orbit, each big enough to damage a satellite or telescope, even a space shuttle. This space junk may be very deadly, a tiny speck of paint from a satellite dug a pit ¼ inch wide into the window of a space shuttle.
