On Mars (they do have a sky there, right?)
The planet Mars may be in for a collision from an asteroid headed its way. Scientists from NASA have been tracking the 160-foot-wide asteroid for some time now, and say the odds of it hitting the Red Planet are about 1 in 75. Back in 1908, Earth was hit by a similar asteroid, near Tunguska, Siberia. That impact flattened millions of trees and is thought to have left a crater that is now a lake.
