"Usually when an asteroid is headed toward Earth, I'm not rooting for an impact." But "I think it'll be cool," said Don Yeomans, who heads the Near-Earth Object Program at NASA's Jet Propulsion Laboratory.
Don is referring to the potential impact of a football-sized asteroid with Mars, our second nearest heavenly neighbor. According to calculations, the impact would not affect earth, but would create a half-mile wide crater and release an amount of energy similar to the 1908 asteroid that struck Siberia, leveling 60 million trees. The current odds of impact are 4%. Keep your fingers crossed...
