Space junk threatening space station

CAPE CANAVERAL, Fla. -- A small piece of space junk drifted dangerously close to the International Space Station on Tuesday, prompting NASA to order the three astronauts to seek shelter in their attached capsule.

Mission Control gave the order after determining there was not enough time to steer the orbiting outpost away from the space junk.

The debris - estimated to be about 6 inches square - is from a Chinese satellite that was deliberately destroyed in 2007 as part of a weapons test. It was projected to pass within three miles of the space station, warranting a red threat level, NASA's highest.
