P.S. is it me or does all the cool stuff happen to the usa.... So small in size but large in stuff happening....

Re: OT- Impact of an asteriod hitting Eastern USA
 

So small in size? Out of all the nations on Earth, the USA is something like 5th or 6th in both geographical size and population. That's small?

Re: OT- Impact of an asteriod hitting Eastern USA
 

Even though it's probably 25 years or so since I've read Robert A. Heinlein's The Moon Is A Harsh Mistress, there was one thing in that book that always stuck in my mind. IIRC, the moon population was rebelling and trying to become an indepent state. In one scene, the moon miners, insteading of sending moon rocks in a controlled descent to earth, rigged the machinery so that they were using it as a weapon and hitting whatever targets they wanted to. I've always wondered that if we could ever get a moon colony going, if such a weapon could be made and we could take shots at whoever we wanted to. Imaging sending a big rock at Tehran? Or Syria? Or maybe once China makes whatever move they have in mind?

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">Not really the problem is in definitions. Yours is Land Area mine was actually (I mislabeled it) Total Area.

Total Area is international borders and so counts inland water bodies etc. The other is just the land, and subtracts any area covered in water. The US has about twice the water area of China so Total Area is larger for US while Land Area is larger for China. http://forum.shrapnelgames.com/images/icons/tongue.gif

And something fun to make your own comparisons with other nations.

Re: OT- Impact of an asteriod hitting Eastern USA
 

CBC television in Canada had an interesting 2hr program at 8pm EST tonight called "Asteroid! The Doomsday Rock". I thought it was done rather well - especially compared to those normal Discovery Channel/TLC ones that are on sometimes. It covered the actually Groups/agencies that are responsible for identifying and tracking many of the asteroids that could potentially harm Earth at some point and developing possible methods for diverting a potential impact. Interesting stuff.

Re: OT- Impact of an asteriod hitting Eastern USA
 

i always thought a bunch of nukes would pretty much take care of any asteriod. but maybe i'm just revieling a liking for brute force. nah. i think the hammer's already did that. http://forum.shrapnelgames.com/images/icons/icon10.gif

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">You're lookking too much cheap american TV http://forum.shrapnelgames.com/images/icons/icon12.gif Vacuum = no atmosphere = no air pressure = pretty ineffective nukes. Even if you make very deep tight holes into an asteroid and bLast there, you will probably end up with just several pieces hitting earth instead of one. It would be more effective if you cover the asteroid in white paint and let the sun deflect it.

Re: OT- Impact of an asteriod hitting Eastern USA

Re: OT- Impact of an asteriod hitting Eastern USA
 

well, if you nuked one side of it, you could deflect it.

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">lol, really stop looking cheap bad TV films http://forum.shrapnelgames.com/images/icons/icon12.gif In vacuum, you just DO NOT GET any sigificant kinetic energy from a nuke. You get heat and radiation. ONLY ON EARTH, or within any other atmosphere, you have pressure, and therefore the destructive kinetic energy, resulting from it. Despite what every SciFi film tries to tell you, you do not even hear a bang! http://forum.shrapnelgames.com/images/icons/icon12.gif

Re: OT- Impact of an asteriod hitting Eastern USA
 

yes, i know you don't hear a bang. unless you stick your helmet on the asteriod, in which case the concusive force is transmitted. and there is concusive force, wether there is an atmosphere or not. and several sci-fi auther's have written about using nukes.

Re: OT- Impact of an asteriod hitting Eastern USA
 

What if you bury the nuke fairly deep in a shaft on the asteroid before detonating?

As for "only the US and Tokyo have fun events", I think it depends on what media you listen to. Watch British sci-fi, for instance, and you'll find that 999/1000 omnipotent space beings prefer the British Isles as the keystone of their master plans.

ok, i just can't understand how you can have what is essentally an explosion without force.

Re: OT- Impact of an asteriod hitting Eastern USA
 

There would be lots of force, but not much to push against, except the missile itself. That's why I was suggesting burying the bomb in the side of the asteroid.

The "paint it white and let the sun deflect it" is a much more appealing idea, as is intercepting it at a great distance and attaching a solar sail.

Re: OT- Impact of an asteriod hitting Eastern USA
 

Hmm, that's a good point, a nuclear explosion produces only radiation and heat.

Well, maybe they can deflect the asteroid by exploding a very big conventional bomb (not a nuclear one). The explosion will generate force from the expanding gases, which can transfer kinetic energy by striking the side of the asteroid.

Re: OT- Impact of an asteriod hitting Eastern USA
 

i guess the point is that the nuclear missile itself doesn't possess enough mass to transfer enough kinetic energy to the asteriod? but then why does it refer to the force of the nuke in multiple's of tons? in table 7.

Re: OT- Impact of an asteriod hitting Eastern USA
 

Narf, nuke warheads are always measured in kilotons of TNT, the amount of that required to produce an equvilent explosion.

The problem is in space, you have no air. No air and you have no overpressure, no bLast wave..no concusive effects. Its conciveable that even the space shuttle could survive a fairly near miss with a nuke in space, most of the force is lost.

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">I doubt that. It is still a HUGE amount of energy reliased. Lack of air removes the shock wave, but insted we will have a stream of sublight-speed particles that are no longer opposed by atmosphere density. We will still have the same sort of "front wave", now propogating with the speed of light. If you remember from nukes explosions, staff around the center was evaporated. It is caused by photons, not a shockwave !

Re: OT- Impact of an asteriod hitting Eastern USA
 

maybe drill into the astroid and release the bomb ??

Depends how "near" the near miss is I suppose, though you're right the shrapnel might be nasty.

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">Well, if you think of sublight-speed particles, you should certainly not select photons http://forum.shrapnelgames.com/images/icons/icon12.gif . Also, there is relatively few resistance to them (or other particles) from atmoshpere density, at least here on earth. Not even on Jupiter. Except on diskworld, I have not yet seen light been slowed down by air http://forum.shrapnelgames.com/images/icons/icon12.gif .
If you mean alpha particles, neutrons, or anything else like that - the evaporation of the staff in the center may be caused by them, but not via measurable concussive force. This is matter destruction on a molecular/atomic level, and while you may be able to turn a small portion of said asteroid into dust its course will not be affected in any way.

Re: OT- Impact of an asteriod hitting Eastern USA
 

ok. but i suppose if we really want to know, we're going to have to blow up a nuke in space.

Re: OT- Impact of an asteriod hitting Eastern USA
 

<font size="2" face="sans-serif, arial, verdana">Are you sure? It happens every day for me...the speed of light here through air on Earth is .9998c - a measly difference of just under 90,000 m/s.

Re: OT- Impact of an asteriod hitting Eastern USA
 

In fact certain cosmic particles have exceeded the speed of light... in the earths atmosphere where the speed of light is marginally slower than in a vacuum. Ever heard of Cherenkov radiation? The Sonic Boom of Light Speed? http://forum.shrapnelgames.com/images/icons/icon12.gif

Also the largest nuke ever detonated on Earth by the old Soviets was not measured in kt but in Mt 50 of them to be exact. Most are kt due to reduced efficiency in larger explosions compared to smaller ones for military purposes. The largest bomb ever built again by the Soviets (same as the one they detonated actually) is 100Mt. If ever used to full effect it could increase global fallout from a nuclear war by 50% all by itself. http://forum.shrapnelgames.com/images/icons/tongue.gif

Re: OT- Impact of an asteriod hitting Eastern USA
 

Oh yah. And solar sails and painting it white would only work with significant lead time on the asteroid. The current expected lead time on an earth impacting asteroid is not sufficient for such methods to work. You would have to detect it years out and have the system you plan on using on the asteroid already ready to be deployed. After all it has to be setup, launched, get to the asteroid, and then deploy whatever it deploys, and only after sufficient time will it alter the path.

For discovering something a few days or months out about all you could do is launch all the earths nukes at it with your best missiles pray, have a party whatever your pick is and hope enough get their to vaporize it. Nukes won't change the path but enough of them in waves can vaporize just about anything. There are advantages to having an internal explosion core temperature that exceeds the temperaturs of the sun. http://forum.shrapnelgames.com/images/icons/tongue.gif

I actually saw one of these suckers as it exploded over the city.

And no one detected this sucker until it exploded into smaller pieces over the city.
