Blowing up satellites in orbit is a bad idea

Specially when even orbiting specks of paint can punch a hole in the shuttle. The following image shows the growing space debris in orbit around earth over the last 50 years. From Wired.  [Link]

Space debris is an increasing problem. Johnson noted that from the 1960s until the past year, orbital debris had increased linearly, despite advances in decreasing the amount of debris left behind per trip to space. But recently, a Chinese missile test on a satellite and the collision of two satellites in orbit, sent the amount of space debris up considerably. The satellite collision alone increased the risk to the upcoming May shuttle mission to the Hubble Space Telescope by 8 percent.

That complicated an already unusual mission. The Hubble Space Telescope, orbiting at 340 miles above Earth’s surface, has a far more densely crowded space debris environment than the ISS. The orbits near 560 miles are the most crowded with junk.

We already know small impacts occur regularly during shuttle flights. Wired Science obtained the Hypervelocity Impact Database last month, which revealed that in the 54 missions from STS-50 through STS-114, space junk and meteoroids hit shuttle windows 1,634 times necessitating 92 window replacements. In addition, the shuttle’s radiator was hit 317 times, actually causing holes in the radiator’s face sheet 53 times.
