"Recent near misses between orbital debris and the space shuttle on its mission to service the Hubble Space Telescope only serve to highlight the problem. In fact, NASA’s Steve Stich believes the risk of a micrometeoroid or orbital debris (MMOD) hit is the greatest risk to the shuttle program. According to the Hypervelocity Impact Database obtained by Wired Science, in the 54 missions from STS-50 through STS-114, space junk and meteoroids hit shuttle windows 1,634 times, which required 92 window replacements, while the shuttle's radiator was hit 317 times, punching holes in the radiator's facesheet 53 times."
