Space station may have to duck orbiting debris
Another piece of space junk is drifting toward the international space station just as the space shuttle is headed that way.
NASA will decide later Monday whether to fire the space station's engines to nudge it out of the path of an orbiting piece of a Russian satellite.
The satellite debris is projected to come within about half a mile of the space station early Tuesday.
Space station astronauts had to move into an emergency capsule last week for about 10 minutes because another piece of space junk came too close for comfort.
A NASA spokesman said if the space station has to move, the shuttle Discovery that took off Sunday will have to adjust its course slightly to be in position for docking on Tuesday.
