I understodd the missile defence system would have a very tough job shooting down a missile, but apparantly they are pretty good against satelites. Can anyone confirm or deny this?
As long as people are going to buy things they don't really need with money they don't actually have, America wil remain in a credit crisis.

China just showed how easy it is to take out satellites.
One detonation in the right place will render nearly all orbits null and void.

The first acknowledged maneuver to avoid a piece of debris from the Chinese ASAT test occurred on 2007 June 22 when flight controllers at NASA's Goddard Space Flight Center briefly fired the thrusters on their TERRA satellite to avoid a 7 percent chance of being struck the following day:
* Space.com, "NASA's Terra Satellite Moved to Avoid Chinese ASAT Debris"
Several analysts have suggested that the debris from this event would be relatively short-lived and only remain in orbit for ten years or less. Unfortunately, nothing could be further from the truth. A detailed analysis of the lifetime of the debris cataloged so far—using the Lifetime model implemented in STK—shows that just under 7 percent of the debris (135 pieces) will have decayed within ten years and 79 percent will still remain in orbit 100 years from now. The majority of the debris from this one event will remain a hazard for centuries to come. (Note: This analysis was only done for 2,030 of the 2,087 pieces catalogued to date since it appears that 57 pieces are currently missing from the catalog.)
In Russia's continuing policy of seizing private assets, they are trying to locate and arrest another Russian oil capitalist:

oh stop. if you actually look at what these guys did post fall of soviet union it's actually better then him getting lynched by the millions of Russians he screwed.
Do you really think that what happened post Soviet-collapse is capitalism, I really don't know what to say. It is a bit like saying that Gaddafi's sons are capitalists or that Suharto's family is capitalist.
Is it a total coincidence that 80% of the oligarchs happened to belong to a faith that encompasses one half of one percent of Russia's population? I'll let you guess which religion that happens to be.
Alfred: You mean it is like saying Goldman Sachs is a capitalist enterprise?
i find anti-semetism offensive. You really need to go find a neo-nazi website Bob Ebersole
The ethnicity or religion of the oligarchs is one thing, the economic system they have in Russia is another. There is no doubt that it is capitalism, whether the capital is in the hands of the oligarchs or in the hands of the bureaucrat capitalists around Putin.
I laugh at people who think the Jews control everything. My wife is Jewish, as is my son's wife and her family. Her mother works as a sales clerk and her father as a security guard. He was UPS driver before he retired.
There are certainly rich Jews, but at the very top of the heap here you mostly find my people -- WASPs. Unless Cheney converted? But this is all quite beside the point. Capitalism isn't about religion or ethnicity -- it's about money. The billionaires of whatever background love to stir animosities between people. Cheney has no affinity whatsoever for his Appalachian kinfolk, nor does the elite of any backrgound.
A lot of anti-semitism is aroused by Israel's criminal actions just as a lot of anti-American sentiment is aroused by the US gov't bombing the crap out of anything or - one that moves. But the Israelis are pawns in the hands of their elite just as we are of ours. Norman Finkestein points out that a lot of the Russian "Jews" in Israel are not even Jewish!
Think interests, think economics -- don't think ethnicity or religion. End of rant.
Really well put. Thanks. Good ending.

Thank Dave - and Matt,
Second the sentiment.
And possibly add, sometimes the "interests", as well as the "economics", are conducted via connections people have. And what people believe (or imagine) themselves to have in common with others may be part of that. Though the beliefs about commonality may be artifacts, too - as opposed to motives.
I think any statement calculated to build up hatred of others is against my principles and values, and I'd prefer not to see it here. We all need to work together.
Unfortunately, I find neo-cons distinctly unlovable.

In the 80s, someone (probably Arthur C Clarke) pointed out that the Russians could destroy the Star Wars satellites by throwing a bucket of nails out of the Mir space station.
thats because satellites are easy to hit. take the orbit and determine when is the best time to launch to send something to hit it. The orbit is either geostationary or on a set path making the knowledge of where it will be easy.
warheads on the other hand are more chaotic. shooting down a missile is more like you trying to knock a bullet out of the air with another bullet, mathematically possible but due to the time scale involved it's not practically possible.
You need one of these babies,
http://en.wikipedia.org/wiki/Tactical_High_Energy_Laser
Coming to an all electric SUV near you soon!
i have heard of those, they are still NOT fast enough in everything but the speed of the laser. they heavily rely on radar to target. as fast as the servos on the emitter point are they still can't move that fast. not to mention the charge up time for the laser, and the fact that the laser MUST hit stay on the target for a little while to heat the projectile enough to make it blow.
Also, consider that chemical lasers like these do not run on electricity at all. A chemical laser is like a rocket engine. Explosive fuels go in, laser light comes out.
The laser you mentioned burns $3,000 of chemicals per shot, including deuterium which costs abut $20 a gallon.
Any energy weapon, by definition according to thermodynamics, consumes more energy than it produces. No matter what kind of laser weapon, each shot requires burning more fuel energy than the energy in the laser.
Accurate enough. The question then becomes - why did the Chinese undertake this relatively low tech. test and create so much space debris? Just to screw the world for the fun of it?
Also to demonstrate that your precious navigation satellites and spy satellites won't live much longer than aircraft carriers in a real shooting war.
The original poster (TrueKaiser) implied that, that is already obvious, i.e., it is easy to kinetically destroy satellites and create space debris. The folks in the armed forces know it - was the intent to also make it obvious to Joe Blow on main street?? - and how about the 2200 pieces of space debris that was created and will be around for 100s of years?
Was the intent to make space unusable for others?
As far as a shooting war goes - ICBMs have inertial guidance systems and are independent of Satellites and GPS. The Chinese have many of these, as do many others in the rest of the world. So destroying satellites will not prevent retaliation.
Below is a link on inertial guidance of ICBMs.

The Chinese aren't trying to project force over the entire world, only the US is. They would be quite content for now just to sweep the US away from their periphery. Thus, they really don't need to know the exact location of something in Germany or Peru or Cameroon -- just in China proper or a few hundred miles beyond their border. Thus, they could get along just fine with every GPS satellite knocked out; it is the US that would be in trouble. Ditto with the spy satellites. They would probably like to spy on the US via satellite, but they undoubtedly have more and better human intelligence over here than we have over there, so they could get by without their spy satellites if need be.
The only satellites that the Chinese really need are their geostationary ones. It is a little harder to knock those out, for they are a lot farther away. The funny thing is, though, that you could do so without putting most other satellites in geostationary orbit at risk - partially because there is considerable distance separating each, but mostly because the debris would be blown into a non-geostationary orbit.
Knock out our cable TV -- now there's the ultimate weapon for you; hit the US where it REALLY hurts!
Agree.
