Oooh! That must have hurt!

If two satellites collide in space, it makes no sound.... (except in star wars movies).

I'm just surprised more satellites haven't collided. The debris is sure to be a hazard, even though they say it won't be. Thousands of high velocity bits orbiting the earth, adding to the 13,000 already cataloged.
