Getting Crowded in Space

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
