Save the Earth: Hit asteroid with spaceship

It sounds like the plot of a bad Bruce Willis movie, but some experts are saying it should be a reality. In order to prepare for massive asteroids that could aim for Earth in the future, researchers should ram a spaceship into a real asteroid to see if the space rock would shift course, scientists say.
