NASA's Upper Atmosphere Research Satellite (UARS), an
observatory that was launched in 1991 and decommissioned in
2005, may have collided with another large object in space,
according to a report on LiveScience. U.S. Air Force Space
Command first cataloged four pieces from the satellite in
November. Around that time, debris from Russia's Cosmos 1275 was
headed towards it. A collision wasn't a given, but the objects
were close enough to raise suspicion. We've written about the
dangers and oddities of space junk before, but it might become a
more important issue in the future.—Gregory Mone
