Blast I do support his theory, when I use to process the space shuttle for over 10 years we were constantly repairing damage from so called micro meteorites. There is so much junk flying around in both low and high earth orbit from man alone not to worry about space meteorites. At one time it was just the US who tracked space debris and we offered that information to other countries for free. The problem is based on excessive amounts of money and just plain stupidity.

Every third world country wants to get into this game not to mention Russia and Europe who've been in this game for a long time. Every time a rocket is sent into space, everything from paint chips, bolts that are pyro sheared, etc. is cut loose from the vehicle only to slowly return to earth. Depending on how high the rocket goes depends on how long the debris takes to reenter. The shuttle was the only space friendly vehicle designed to keep debris to an absolute minimum. To give you an example we took a hit from a paint chip (no metal) from a old Russian rocket that put a deep hole in a 1/4 stainless steel radiator on the payload doors that came close to breaching the freon core. The shuttle was moving at roughly 17,580 miles an hour and the paint chip was traveling at a similar speed the other direction, the impact was at 35160 mph roughly and the damage was incredible for a spec of paint. It's like how we use water to cut though metal with small amounts of sand in the mix, enough pressure and velocity you can cut through just about anything. Anyhow I know I'm rambling again, sorry but to shorting it up if any debris hits anything in space at the right speed and velocity it's catastrophic and all the tracking stations do is keep the military satellites, shuttle, ISS and the Aurora from hitting big stuffs by warning or sending the command to get clear (which depletes the fuel over time). Any civilian or other countries satellites are fair game and it's up to that country to be proactive. In time I think you'll see more things taken out by debris, the military stuff you'll never hear about it in less you live in Australia where all the junk falls at.

Oops did I say Aurora, that doesn't exist
