Blasting Killer Asteroids
This Popular Science article was almost what I was looking for. I've been thinking a bit lately about whether it's really possible to blast an incoming asteroid to smithereens using a nuclear weapon.
The article didn't explain it to my satisfaction. For one thing, the research is all done with computer models. I'm not set very much at ease by computer models. I think they should try it with real missiles. Maybe send one to the asteroid belt and pick a small one to blow up? I'm not sure it would cost all that much. We already have thousands of missiles and warheads we might be able to use.
It sounds about right, though, with the scientist enlisting some people to take over a nuclear missile silo with intent of taking out a comet, or some such, that's going to impact earth. Problem is, he needs two missiles but everyone thinks he's nuts. The Russians get all jittery when they hear about it and realize he might really be some nutcase that wants to launch on them.
Made for a great movie for me and the end turned out to be a real feel- good, if not a downright tear jerker. That assumes this is the same movie I'm thinking about. Keep an eye out for it should it be on TV again.
