US Satellites Dodging Chinese Missile Debris

GSGKT writes "Today's Washington Times runs a story about the increasing problem with space junk orbiting the earth. Debris from the anti-satellite missile test by the Chinese military last year threatens the integrity of more than 800 operating satellites, half of them belonging to the US. Two orbiting U.S. spacecraft were forced to change course to avoid being damaged soon after the incident. Air Force Brig. Gen. Ted Kresge, director of air, space and information operations at the Air Force Space Command in Colorado, estimates that "essentially (Chinese anti-satellite tests) increase the amount of space debris orbiting the Earth by about 20 percent", and the debris might threaten spacecraft for up to 100 years."

SanctionThem?

[Adambomb]

I find the tag of sanctionthem rather odd as how, realistically, would one impose these sanctions? Economic sanctions would be met with retaliatory tariffs; Do not forget that economically, North America needs them more than they need us (i'm not sure of the situation for the rest of the world).

What's left, political pressure? Because of how much China listens to political pressure concerning their own policies? Military pressure?

I do not see it.

I think the SanctionThem was meant to be sarcastic.

With the US economy decelerating and the loss of confidence in the US dollar, the US can't afford to stop trading with China. This move would essentially crash the global economy, and the US has the most to lose due to its massive foreign debt.

Most people don't realise just how rotten the American economic policy is. Back in 71, Nixon realised that the US could no longer finance the Vietnam war without printing money like mad. But the gold standard prevented the Fed from doing that, so he unilaterally cancelled the Bretton Woods system that made the US dollar convertible to gold. This was a total surprise, because he neglected to consult international bankers, and became known as the Nixon Shock. So from that moment on, the US effectively started printing gold. Of course this move didn't fool the bankers around the world, so the Fed had to raise interest rates to 21%/year to convince them to carry on using dollars. Over many years, the markets sort of returned to normal, despite the fact that the US debt had risen to unprecedented levels.

In 2006, the Fed was printing so much money that it stopped publishing the M3 money supply data in order to hide this fact. So now no one really knows how much money the Fed prints. We just estimate that the US foreign debt grows at the rate of $3 billion per day, mostly due to overseas military spending and interest on the already existing debt. This is despite the fact that the US is creating money out of thin air to partially cover this debt. A consequence is that the dollar has fallen in value about 15% in the last year against the Euro.

It bothers me a lot when the Fed governors propose what they call "financial incentive packages". These are usually composed of tax rebates and the central banks injecting money into the markets. Again, it's more money that was created out of thin air, and the tax rebates reduce the government's capacity to cover that money or to cover the debt. It's a temporary fix to the longstanding lack of financial discipline.

The general population typically doesn't care, and this includes Slashdot readers. They think that economics is awfully boring and complicated, and that the government is capable of taking care of policy. But the opposite is happening, and the US debt is getting out of control. This spending obviously makes politicians and contractors a lot of money, so they'll keep doing it until the economy crashes.

That's backwards. The US has the least to lose, because a debt represents a good that we consumed but have not yet paid for. The first order of business in an economic collapse is to freeze or otherwise abate all foreign debts.

That would essentially mean that the end of all trading. So, the US would have to revert to a self-sustaining economy. US consumes the most resources in the planet per human being and that is not really feaseable.

Either that, or we would just fail to make the payments. That would crash the value of all foreign debts, and so the holders would be lucky to get ten cents on the dollar by selling their paper to speculators (who are betting that we'll pull out of it).

That would lead to imports crashing as well. Then, prices would go up and cause inflation. Then, everything will be worth less and less and foreign buyers will just buy up everything - companies, technology etc. Our stuff will also be sold on ten cents to the dollar out there.

This is why China dearly wants to avoid harming our economy. When somebody owes you an entire year of their salary, and is so far making payments on time, you don't knock them out of a job!

That is until the Chinese economy is the largest in the world which might be in 10-15 years.

Indeed, in the long run, US foreign debts guarantee that other countries align their interests with our own, and look out for our well-being as one would keep an eye on one's best milk cow.

It's only best milk cow as long as the milk flows.

I've seen so people many buy shit they can't afford, live in the moment, default on loans and then file bankruptcy which absolves them of all responsibility since somebody somewhere will bear the burden of it all. I think you're suggesting a similar approach to the economy. I am skeptical of this approach.

Re:Huh?

[palegray.net]

Because our junk isn't the result of intentionally detonating explosives in space with the aim of developing technologies designed to disrupt communications, which is kinda the point of the story.

Re:That's a laugh!

[Adambomb]

What in the hell are you talking about? Theres more to prosperity than oil.

Remember who bought up all the steel reserves and is now slowly selling it back to the US? Have you ever been inside ANY manufacturing plant...at all..ever?

US industry would SHUT DOWN ENTIRELY if china pulled the plugs, or be cripplingly disadvantaged compared to the rest of the world if they decided to place punitive tarrifs. And if you think this is limited to crappy dvd players and laser pointers, do not forget that factory farms that are responsible for your daily food run off harvesters and harvester parts made primarily from components from china.

Do you have any idea how the world around you works at all?

Re:Possible outcome.

[gmack]

Which would risk more debris in the atmosphere as the Chinese target every American spy satellite they find to erase the American technical advantage to one of pure numbers where the Chinese have the advantage.

The US military is completely dependant on their technology and the rest of the world knows it. Do their cruise missiles even work without GPS?

Any war by the US against a significantly developed nation runs the risk of rendering space completely useless for the next century. Think about the collateral damage from such a war taking out weather/TV/communications on top of the GPS which would almost certainly be targeted on purpose. The economic damage from that stupidity would be huge.

Letting the Americans know that was most likely a major reason behind the missile test in the first place and it's also why the Americans won't retaliate.

Re:Well

[CrazedWalrus]

If that wasn't the intended effect and was just a fortuitous (for them) side-effect, you can bet they've learned the lesson, and that it *will* be the intended effect next time.

"We didn't attack your satellites, we attacked our own (*cough*and used it to create a floating fragmentation grenade*cough*)"

Re:Huh?

[vtcodger]

Assuming that Reverend Moon's right wing slag sheet has something right for once, half the debris threatening satellites being American wouldn't be far off since almost all of the 80% that was there prior to the Chinese test was put there over the past 50 years by the US and USSR/Russia. But the Chinese test really does seem to have been irresponsible. Presumably they could just as easily have done their test at with a lower altitude target where the majority of the debris would have decayed and burned up in the atmosphere in a few hours, weeks or months.

Does point out a problem with space warfare though. With current technologies or anything resembling them, there's only going to be one battle and a short one at that. After a few dozen satellite destructions, there will likely be so much junk in orbit that near earth satellite lifetimes will be measured in weeks and manned spaceflight will be ill advised for decades or maybe centuries.

Re:Possible outcome.

[WED Fan]

but I've heard that...

Yeah, many great statements have always followed that opening.

Consider that GPS, when functional, is used to seed initial starting positions, but inertial nav packs are used to provide guidance. Other back up systems include other inertial nav packs, stationary fixes, and celestial navigation.

Consider that the GPS system can be knocked out. But, it's pretty damned hard to change the known locations of fixed locations, its damn near impossible to block good old centuries proved navigation by heavenly objects (unless the Chinese have an unknown deal with Klingons and Vogons) and with modern time keeping and the ability to shoot the stars with computer, it is surprising accurate.

Had you involved yourself at all with your country's military, beyond letting the press inform you, you'd have never made this mistake.

But, you can go on with your, "My best friend's sister's boyfriend's brother's girlfriend heard from this guy who knows this kid who's going with the girl who saw Ferris pass out at 31 Flavors last night. I guess it's pretty serious."

Pullllease, "I heard that..."
