Two satellites, Iridium 33 and Cosmos 2251, made the news a couple of weeks ago when they accidentally collided 400 miles above the Earth. This was a rare occurrence, but the possibility of further collisions has now increased. The resulting orbital debris from the collisions is being tracked by Norad and other services. Celestrak is providing data on the debris from the collision. Rob Simpson of Orbiting Frog has released a Google Earth network link [Google Earth Required. You must have GE installed.] that lets you see the current orbital positions of some of the debris from the February collision. The file automatically updates with the current orbital positions.
