After last week’s collision of two satellites in space, experts estimate tens of thousands of pieces of space junk that they will now have to monitor. They already track over 17,000 pieces larger than 2 to 4 inches in diameter. The incident occurred between a U.S. Iridium commercial satellite and a derelict Russian military one about 500 miles above the planet. The FAA has received reports of falling debris over Texas, which could be related to the crash but was not confirmed. Either way, it may be 10,000 years before the floating stuff, seen in this artist’s rendering, will not be a threat to other satellites.
