dude they completed the mission all though the astroid would not even come close to the earth the gole was to hit the astroid to see if they could do this in the future to save earth when one actually hit earth

ok just to clarify to everyone so they stop being difficult, the astroid never would have hit earth or done anything it would have just went past and nothing would happen. {Ok?} and why they hit the astroid is becuse they wanted to see if it was possibel to hit one and send it off corse becuse if an astroid was going to hit earth in like 2000 years then we would have the tecnolighy

Nah its pocket change

Yezzzz final some one is smart every one els that commented on this was like oh nasa thanks for saveing the earth.. but know one actuley read it the thing was not evne going to hit the earth:))))
