Re: NASA's deep impact
it will just keep going on its way, they will be doing the impact once it passes the earth so that there is no way it could affect the Earth.
What really confuses me is that even after they do impact it they will just have pictures, how much can pictures tell, they would want/need asteroids core samples after the impact, and since its the closest body to the impact any debree from it will continue to follow the meteor.
i guess pictures will be able to tell some, but not all.
