Averting a collision with asteroids

Chicken Little was right. The sky fell again, this time over the city of Chelyabinsk, Siberia, on the morning of Feb. 15, 2013 when a meteor exploded, injuring almost 1,500 people and damaging more than 7,200 buildings. Some of the startled Russians immediately thought that it was an American ICBM and that a third world war had started.
