Junk could threaten space station
A small piece of space junk is drifting dangerously close to the International Space Station.
Nasa has ordered the three station astronauts to seek shelter in the Russian Soyuz capsule that is docked at the orbiting complex. A spokesman said there is no time to steer the station out of harm's way.
The debris is from a Chinese satellite that was deliberately destroyed in 2007 as part of a weapons test. It is projected to pass within a couple miles of the space station.
An American, an Italian and a Russian are aboard the space station.
