Comet-Blasting

So our NASA engineers have design a comet probe -- dubbed Deep Impact -- that will smash into the Comet Tempel 1 millions of miles away near Jupiter at about 23,000 miles an hour on July 4, snapping images until the last minute. The probe is designed to give researchers their closest look yet at a comet's surface and help decipher the origins of the universe, as comets are remnants of the beginnings of solar systems after the Big Bang. Comet-Blasting Mission is 'Go' for Launch [MSNBC.com].

But if that's the case, why can't our Pentagon engineers make a suborbital rocket that can hit an inbound nuclear missile? "Star Wars" for comets, but not people. Food for thought.
