Finally an excuse for space nukes.

And finally a use for the Space Station.

The Russions dumped MIR..... A use for the ISS would drain taxpayer money for many more years. Maybe if you added a huge foil with for example a Coca Cola commercial that could be seen from earth, then it could pay for itself.

I have this idea: extend some beams from the ISS and make some ultra high power LEDS on these /\\ | flight direction

-0-0-0-0-0-0-0-0-0 -ISS-0-0-0-0-0-0-0-0-0- Now think of this as pulsed, one vertical character row. If you switch row after row of a text or simple grahics, then because it moves you will see the text or whatever from the ground. Like this, but then _much_ bigger:

But existing ICBM's don't manage escape velocity. The ISS could be studded with wide-field telescopes to find nasty objects, and have a dozen or two nuke-tipped rockets ready to go. Being in orbit, outside the atmosphere, is a huge head start.

Busting the asteroid up would just convert one 400-megaton equivalent into three 100-megaton and 10 10-megaton ones, all still coming at us--big improvement, huh?

Pushing it out of the way is really the right answer, assuming they get their sums right.

Just an observation about the futility of bans on "weapons in space", a thought generated by Jan's use of the word "excuse".

yes,the only problem is keeping them all aimed -outwards-. ;-)

It's no fun to blow up nukes in space because there's only the flash - no big fireball like on a planetary surface.

But who needs an "excuse" to go explore the Universe? What ever happened to "because it's there"?

Thanks, Rich

OTOH,it -might- break the object into pieces small enough that they would burn up in reentry,or not have a catastrophic impact.It might reduce the 'big' impact to a lesser-damaging one,by spreading more of the mass over a wider area. Not all asteroids are solid masses. Many are smaller rocks and gravel bound with ices.

At least it's worth a try,better than doing nothing.

Take the bunker buster idea

and make a make a few changes...

1) It's a bunker buster missile. 2) It's basically a spear. Maybe a depleted uranium tip.

This type of missile doesn't explode or gets damaged on impact with the asteroid. (The missile contains as much propellant as possible.)

Fire hundreds of these bunker busters at the asteroid at strategic locations. The asteroid probably has spin.

Then by remote control individual missiles can be controlled to fire at the correct times. Not to explode, but to ignite the rocket engines.

But I suspect this is still like ants pushing a bowling ball.

Got one more idea..

1) locate ice asteroid 2) steer ice asteroid to land on killer asteroid... (There's a toughy) 3) use a nuclear reactor to vaporize the ice to create a powerful jet like Old Faithful. D from BC

I'm not sure "outside the atmosphere" is all that important. The

17kmi/h delta-V is though. You have to get that delta-V somewhere to begin with though.

We should fire a nuke on the surface of the moon, just for the flash. That would be cool.

We should certainly explore the universe. But not with people.

Yes that is true, but I ment nuke _testing_ in space. Those guys in the US are using simultations (maybe that is why somebody here wants an ultra high performace graphics system ;-) ), they want to really test their designs. Now they can.

It is no fun if you cannot dance with the martian girls. Only cybersex with the Venusians? Kirk beams down.

The difficulty is that there's still all this mass coming at you at the same speed as before, and due to arrive all at the same time.

If you were a duck, would you rather be shot at with a rifle or a 12-gauge?

That's not true! I've seen it in the movies!

Perhaps the incoming asteroid is the first shot.

even with all those missiles/rocket motors,you still would not get anywhere near the same impulse as a single nuclear explosion.
