It's getting to be real crowded up there. Today, Russian aerospace authorities had to shift the orbit of the International Space Station to get it out of the way of a piece of hurtling debris.
A similar maneuver was planned just a couple of months ago when a piece of China's Feng Yun satellite threatened the station. This time, the junk is American, a piece of UARS.
Is it almost time to deploy the giant space nets? Or will we have to wait till space junk disables our communication networks and lands in our backyard?
