Collision Course? A Comet Heads for Mars
Huntsville AL (SPX) Apr 04, 2013
Over the years, the spacefaring nations of Earth have sent dozens of probes and rovers to explore Mars. Today there are three active satellites circling the red planet while two rovers, Opportunity and Curiosity, wheel across the red sands below. Mars is dry, barren, and apparently lifeless. Soon, those assets could find themselves exploring a very different kind of world. "There is a small but non-negligible chance that Comet 2013 A1 will strike Mars next year in October of 2014," says Don Yeoman ... read more
