TOTAL nuclear disarmament may actually put humanity in danger. Scientists have said nuclear bombs may be our only chance of surviving a meteor attack like the one which wiped out the dinosaurs.

A scientist from Iowa State University, Bong Wie, told the 2014 NASA Innovative Advanced Concepts meeting nuclear bombs could be used to destroy asteroids and space rocks headed for earth, according to a report on Space.com.

Wie said he and his team are developing a concept spacecraft called Hypervelocity Asteroid Intercept Vehicle (HAIV). The idea is the HAIV would be blasted into space to meet the threat and blast a crater into the asteroid with a kinetic impactor.

The nuclear bomb, which would be a millisecond behind the HAIV would then detonate inside the crater, shattering it into millions of tiny pieces. Wie said the project could work with less than a week’s warning.

Wie said the scientific community got a wake-up call this time last year when a meteor exploded over the Russian city of Chelyabinsk, injuring more than 1,500 people. And he thinks it’s only a matter of time before another biggie is barrelling through space headed for Earth.

Wie said a 300 metre wide asteroid could be neutralised outside of the Earth’s gravitational pull a month before projected impact. The worst that could happen is a meteor shower or 100 Chelyabinsk-type events, which sounds bad but the alternative would be destruction 150,000 times worse than the nuclear bomb dropped on Hiroshima.

And the cost for each nuclear asteroid-killing mission? Only USD500 million. A small price to save civilisation. Mark Zuckerberg could fund it out of his pocket money.

@Brown Antony Cruz,
maybe Dr Wie hD ONE TOO MANY "BONG HITS"
dID HE EVER HEAR OF THE Law of conservation of energy?

If you blow up a meteor, you will, more likely have a real mass of pissed off meteor chunks raining down on us.

According to a book written by a NASA physicist I read in the 90's [John S. Lewis, Rain of Iron and Ice (1996), Helix Books], that's an actual valid concern. If the nuclear bomb doesn't deflect the asteroid but merely breaks it up, the mass of said asteroid is pretty much the same, just in smaller bite sized bits. True much of the asteroid will burn up on reentry into Earth's atmosphere but a lot will still remain viable to pummelize whatever it lands on. Tens of thousands of people will still likely be killed from that rainy day fallout.

@tsarstepan,
I have one question; what size nuke do they plan to use?

Suppose you did break up the bolide--then you'd have a bitch of a radioactive shower. You also wouldn't want to be on the side of the planet facing the nuke when it went off--will everyone know not to look up?

@Setanta,
Precisely!

We could attach cylinders of compressed gas, like they put on small model planes, millions of them, and blast the asteroids off to another galaxy. Of course, then, we could get sued if said asteroid crashes into an alien's house.

@anonymously99,
launching a couple of laser ablation satellites around this thing several years out could (once we have a good sense of its orbital pathway) and chip at it which would delaminate it and would give it some change in momentum to miss us . It would take less than a second or so of arc to noodge it over.
