From CNN.com:

Asteroid could hit Mars in January. A newly discovered hunk of space rock has a 1 in 75 chance of slamming into the Red Planet on January 30, scientists said Thursday.

The asteroid, known as 2007 WD5, was discovered in late November and is similar in size to an object that hit remote central Siberia in 1908, unleashing energy equivalent to a 15-megaton nuclear bomb and wiping out 60 million trees.

Yikes! This could be interesting. I wonder if we’ll get footage from some of our telescopes of the collision if it happens. It could be fascinating, and prescient of things to come for us.
