Bush to blast toxic slushie out of sky
Posts
440lbs of hydrazine (though like you said, that is the most conservative estimate) could be a very different beast than 1000lbs. I would go hash out some more detailed analysis but it really has been ages since I took thermo and I'm sure such scientific appraisal has already been handled -- it's high-school level science.
EDIT I'm assuming surface area is staying mostly the same between these examples -- if the density of hydrazine is really low, then it would have a larger exposed surface area and the exponential scaling might be practically linear anyway.
Were the window of opportunity nearer the actual reentry, they would be able to more accurately predict where it would fall -- and really, they would be able to predict it within a large enough radius that unless it was a superurban area they would be able to handle it on-site. I'm more interested in the latter, really; I see the possible applications of being able to shoot something down in orbit, but I'm more interested in the ground ops angle of containment and capture.
What the hell is a "more dangerous" orbit? It's coming down out of the sky no matter what.
edit: Oh. Well, right now it's slated to potentially land in North America. You can't get any more dangerous because there is no way to pinpoint an exact location. That's why it's so dangerous.
Also, their not considering hitting it with two missiles. Pay attention - they're considering firing a second missile if the first one misses.

If you can make space less scary to the average person, less of a far-away and impenetrable darkness, you can sell the careers and the funding and everything else much more easily. I would love to see the mission coordinators come forward and explain in some detail how they go about planning something like this; make it an educational effort as well as a military one.
That's why I would be more interested in the ground ops, too -- it seems more applicable, and like it would create a better public face for the space program because it seems like more of a practical skill that we're invested in.
edit: I see where you're coming from, though, and I also feel that the average person should have a higher understanding of what actually goes on concerning launching machines and people into space. It's the main reason behind the NASA project that was mentioned in G&T.

If they have a quick, safe, and responsible response it can be wonderful. They get to show how they can protect the public. You're being unbelievably pessimistic, defeatist, and apocalyptic about this entire issue. I know that as Americans we're used to botched federal interventions and cleanup operations, but I'm suggesting that a well put-together one could impress the public and make them feel that it was a more hands-on administration, more pertinent to their lives than they previously thought.
Sadly, education is the very last thing Bush ever thinks about, so the moment will be wasted. I'm guessing that it'll come across like cock-waving to folks overseas, and everyone will forget about it quickly unless something goes wrong.
Hi, how about you pay attention. From the second article:
I even highlighted the important bits for you.
And once again, NA is a BIG target.
You.. you just proved his point. If they miss the tank the first time, they'll fire at the seperated tank. The target the first time around IS the tank itself.
The chances of the debris killing an astronaut is higher than the chance of anyone on the ground being killed. Plus if someone on the ground was about to be killed by the satellite, they could just move the hell out of the way.
I know! This is what I'm talking about!

Imagine a 2,500 hunk of metal moving at max velocity hitting a skyscraper full of people. The skyscraper probably wouldn't stop it. Meaning it's going to plow through everything until it hits the ground. That's no good.
Then of course there's the hydrazine.
I should also insert the obligatory Team America joke:
"By God... it'll be 9/11 times a thousand!"
Again, tiny tiny chance of this happening, but its probably not worth the risk.
Ok, no. That blog is quite reputable, and they dont just make shit up from random people.
I'm not sure if its getting through to you here just how unlikely this thing causing damage actually is. As has been mentioned, not a single person, ever, has been hit by a piece of space debris. This is despite a fair amount of it coming down each year. The odds of someone being hit by a meteor are many order of magnitude larger, and meteors have killed, a couple? Maybe?
You're going on a huge rant, but you're vastly overstating the risk here. Absolute worst case scenario, this thing hits a city, with its tank of hydrazine intact. Impossibly unlikely, but lets go with it. 2500 pounds of stuff hits the ground going a few hundred kph. I'd like to point out that while this might sound like a big number, it is in fact very tiny. If it were all in one big chunk (it wouldn't be) then it would be like a truck falling from the sky. This would hit a road or building most likely, killing a couple people if there happen to be people directly under it when it fell.
Now, there is no way something like this would come down in one big chunk, it wold be spread out over an area. How big an area? Well, it d epends on all sorts of junk. Lets take a few examples here. Say it spreads out over 1 square km. 2500lbs = 1125kg. Over a million square meters, you get a mass of a little over a gram per square meter. Which is nothing, it would be less than rain. Lets take a smaller area, say 100m x 100m. Then you get around 100 grams of stuff per square meter. Enough to poke some holes in anyone unlucky enough to be under it, but most of it would fall on buildings or cars, and would just bounce off.
Basically, if your inside your probably fine, unless a huge chunk comes down right on your head. And that hydrazine?
So if someone happened to be right next to the full tank of hydrazine that hit the ground might next to them, breathing would suck and they'd have to go to the hospital. The chemical properties of hydrazine have already been discussed in this thread; its not going to stick around and form this huge toxic, deadly cloud. Quite the opposite.
Now, this is the worst case scenario, hitting downtown somewhere, it could kill, 20 people maybe? This is if pretty well every chunk takes out a person, which is not going to happen, and if the object itself manages to actually hit a town, which is also not going to happen.
Just saying "it might happen!" doesn't really do anything for me, since the odds are so rediculously against it as to make it an impossibility.
There is no need to worry about bits'n'peices remaining to re-enter after a hit from a Ticonderoga.
Even if you guys are right and this is some kind of imminent danger, you should be more worried about the fact that we only have like 23 SM3 missiles, so what are we going to do about all the runaway satellites in the future?
Basically, there's no way we would waste a multimillion dollar piece of equipment of which we have less than 2 dozen based on the VANISHINGLY small chance that someone could be injured. I don't think it's a big conspiracy either, I really think this is just us thumbing our nose at the Chinese for doing the same thing.
This would be close to the truth, however, the device probably needs to come down anyway.
I spent the last 4 years either chasing or hiding from Chinese submarines, (SSN and SSBN, respectively)
It's been a real give and take, much like the old Cold War.
Luckily, the Chinese submarine force is only slightly less accident prone than its predecessor, the Soviet navy.
Somebody PM me when you guys grow up and I'll continue to debate with you.

By the by, the last post didn't prove his point, because they're planning on shooting the thing twice. Just in case the first hit doesn't completely destroy it. Makes a bit of a hash out of the "don't worry, the first hit will surely vaporize it" argument.
Bottom line: waste of money for a dick-waving maneuver.
EDIT: and the idea that NA is "mostly city" or that the satellite landing in NA would "most likely" hit a city is laughable. Driven through any part of the country past the Mississippi?
Uh... space is a heck of a lot bigger than earth.
If he's truly leaving, he's not going to read it, right?

Any cool stories to tell us? Or is that shit classified?
lol, the guy who is calling people stupid is complaining about immaturity. Funny that!
Tons of stories, the vast majority of which would trigger a war if they got out, but one time we spent a week trailing a Chinese sub by 20 feet listening to conversations in the engineering spaces.
Obviously they never knew it.
I'm glad someone pointed that out. Also, Canada isn't very dense, which is also part of that crazy 'North America'.
I think a greater concern is related to the space debris screwing up other satellites.
No, I am not really communist. Yes, it is weird that I use this name.
For most sensible people, yeah, but that wasn't what he said.

:lol:
Wacky commies.
And cmon, you can't say you have stories that would trigger a war and then not tell them to us.
That's just mean.
So hey, they haven't seen any debris larger than a football and there's now a gradually-dispersing hydrazine vapor cloud starting to enter the atmosphere. Pretty sure they should have saved that Mission Accomplished banner for this. :V
That's a motherfucker of a nice explosion there. If it's not as faked as the moon landing, that is*. Thanks for the video!
