Why can't a satellite in space never hit a human?

Answer 1

Actually, it can. It is a very rare occurrence, but pieces of a decending satellite can hit a person, but since most satellites burn up in the atmosphere, and only large satellites can have piece survive the burnup, the chances that someone will be hit by one is very, very small.

In the Space Station or Space Shuttle, that is a different story. The ground control works to prevent pieces of old satellites and "space junk" from hits the shuttle, or station, or astronauts. In fact, one paint chip from an old satellite or rocket booster did hit the Space shuttle's thick window, causing the outer layers to shatter.
