NASA is watching the International Space Station to make sure debris from a Chinese satellite doesn't pose a threat.

Earlier in the week, NASA's tracking data showed the piece of junk would pass near the station, but not close enough to require an avoidance maneuver.

Today, however, new tracking data suggests that it might pass close enough to require the crew to take shelter in their Soyuz spacecraft when the debris makes its closest approach to the station at 1:47 p.m.

What's up there? A lot.

Here is a link to NASA's website devoted to orbital debris.

And here is a story The Dispatch did on one potential way to blast space junk out of orbit.
