well this is certainly an ambitious mission and a very worthy one as the asterois belt may well be the saviour of the planet as it probably contains much int eh way of minerals that we will be desperately short of in future years, and if we can develop ways to mine them and utilise them it will make further longer space mission easier.

As to the Armageddon type of asteroid mission, that is nonsense. You cannot blow an asteroid up, although given time you could deflect one in a number of various ways. Ion drives could nudge it away from impact if they had enough time, even large solar sails could do the job, again if they had a long enough lead time. For those asteroids that show up on a collision course with only weeks or months there is probably nothing that can be done except stick your head between your knees and kiss your ass goodbye.
Blowing an asteroid up does not vaporise it it splits it into thousands of separate projectiles that still follow a similar trajectory.

i hope that they don't let a woman drive...look what happens when they let women behind the wheel!
