China Shoots Down Another Satellite
An anonymous reader writes "It was reported this weekend that China shot down another of its satellites in January this year. 'The website of Hong Kong-based Phoenix TV said the anti-satellite missile test, if confirmed, is likely related to the missile interception test, which occurred at the peak of a dispute between Beijing and Washington on a massive US arms sales deal to Taiwan. During the interception test, US agencies spotted two missiles launched from two locations from the Chinese mainland, colliding outside the atmosphere, a Pentagon spokesperson said.' I guess ballistic trajectories that intersect with orbital ones don't count as 'weapons in space.'"
in orbit. Great.
Nice way to make even more space junk. Nice going, China. Are you trying to destroy access to LEO over time?
Rhymes that keep their secrets will unfold behind the clouds.There upon the rainbow is the answer to a neverending story
Does anyone know how much of an issue the debris from these satellites are? From the perspective of collisions in orbit more so than what happens when it lands (I imagine the parts are small enough that reentry will take care of them).
Didn't you make enough bloody space junk the first time? NEO pollution is becoming a serious issue, and this isn't helping anyone.
They always want to be the best in everything. Now it seems that the Chinese are trying to become the country with the most objects in earth orbit.
I'm sure there's a reasonable explanation.
With China trying to show off what it can do, what happens if they get enough fast moving junk in the orbit levels that it starts hitting other objects... which will promptly start speeding off in other directions, essentially causing a chain reason, tearing up anything in orbit at that level, eventually making an almost impenetrable barrier of fast moving stuff, blocking any chances at anything going into space for the next several hundreds years?
Is there any way to slow the junk down so it hits atmosphere and burns up?
Many military scholars believe it was targeting the Patriot missile defense system that Taiwan was trying to buy from the US at that time
Orbital rendezvous has been done since the early 60s and that's pretty much all "shooting down" a satellite is - put something in the path of the satellite in an opposite orbit and they hit each other at 36,000 miles per hour (18,000 mph one way and 18,000 mph the other way)- woop tee doo.
Intercepting a missile with another missile in the atmosphere is still something that's not quite there yet - consider all the misses that the Patriot system has at least based upon its performance in the first Gulf War in 1991 (19 years ago!). In other words, the Chinese are just proving that they're willing to put shit in orbit in the way of one of their satellites and they think that's competition for the Patriot system? It that how we're supposed to take it?

This is part of developing the technology to take out GPS and other communication satellites in case of a confrontation with the U.S.A. . Much of the U.S. war fighting capability is highly dependent on GPS and satellite based communication. The Chinese military is preparing to fight a war against the U.S. (this is completely independent of whether or not they are planning to fight such a war). The scary part of this is that even if current planners have no intention of ever fighting a war against the U.S. history has shown that when military and political leaders believe that they are in a position to win such a war they often choose to wage it even if a rational analysis says that it is a bad idea (see World War I).
The truth is that all men having power ought to be mistrusted. James Madison
What absolute bunk. No doubt you are also a staunch believer in the hoax of global warming. There is absolutely NO credible evidence that the near earth space is "polluted". This is all just bullshit big government propaganda, no doubt intended to form the basis for future MASSIVE rises in taxation to pay for a "cleanup" (likely involving the disappearance of plane fulls of cash into union and left wing paramilitary group pockets).
...building a great wall of space junk...
Rational analysis says war is the best way for military and political leaders to gain more power.
Even a losing cause that fucks everyone else can work for them.
The story, on a Chinese website (.cn domain) is reporting that the US is reporting that China shot down the satellite. I'm not sure how reliable any of this really is.
Apparently people have completely missed the point of this article. Space junk, yes it's a problem, but did no one grasp the importance that one nation is capable of SHOOTING DOWN SATELLITES?!?
It's obviously aimed at countering US ballistic missile technology that we're selling to Taiwan. Perhaps not to intercept the missiles, but to destroy US GPS satellites so the US missiles won't track. This is just as important as ballistic missile interception program. There's going to be another arms race to have satellites that can "counter" incoming missiles and missiles that can counter the counter on the satellite.
Lastly, can we please stop arming other countries. It always backfires and we end up getting shot by the same bullets we gave out.
Honestly, the only people who benefit from this China-US military hype are the huge suppliers of military equipment. China and the US will never fight against each other. They are joined at the hip, about as much as California and, say, Idaho are. China needs the US, the US needs China. Stop buying into the paranoid, tinfoil-hat ladden, slashdot reactionary ultra-hyped bullshit that they're feeding you.
Besides, the US can out-nuke them any day if they really needed to. :)
Russia can shoot down the moon!
The problem is that China has a VERY active space weapons program and will not give it up. If you look closely at what they are working on, it should be obvious that it is not about defense, but about an offense. They are
Heck, even the agreement to get FTA and WTA required them to open their money in 2004, quit dumping, quit subsidizing, and drop trade barriers. Yet, they fixed their money against the dollar, they dump more than ever, subsidies have actually gone up (vs 1999), though trade barriers have shifted all around.
China is positioning themselves for a hot war.
I prefer the "u" in honour as it seems to be missing these days.
We aren't too excited, because the USA had this tech (destroying satellite) for some time. If anything it re-establish the BOP which is good thing for peace.

That's what we need. Satellites should be outfitted with pooper scoopers and plastic bags. They should be required by international law to clean up after themselves, and toss the plastic bag at the sun afterwards.
Or maybe one of those "cleanup the side of the road" community walks . . . except in space.
This all sounds silly, but maybe we do need some kinda of special cleanup satellite. It would probably be a great opportunity for the international space community to cooperate, as on the ISS . . . ?

I am no expert in this field, but to me it seems not too far-fetched that the system will also be suitable in the future to get rid of space debris.
China shot down a satallite... and then decaprio woke up.
So is this what that "UFO" was that everyone was talking about the other day?
There's no -1 for "I don't get it."
China is by far the heaviest polluter on the planet. Not only have they surpassed America in terms of CO2, but they surpassed America in ALL other forms of pollution around 2000. How? Because they have little to no pollution controls. And where they put it, as required by treaties, they regularly just turn them off due to the loss of efficiencies. Heck, if CHina's economy slows down to 5% as expected, then around 2019, they will have emitted 1/2 of ALL CO2 that has ever been emitted by man. And if they do not slow down, then around 2015, they will break that barrier. They currently account for just under 1/2 of mercury being emitted. etc. etc. etc.
So, if they have ZERO interest in their own citizens, let alone those in India, Viet Nam, Koreas, Japan, Russia, etc., WHAT COULD MAKE YOU THINK THAT THEY GIVE A CRAP ABOUT SPACE?
I prefer the "u" in honour as it seems to be missing these days.
Let's see... when's the last time China invaded another nation? When is the last time a Western nation invaded another nation?
China = one nation, western nations != one nation.

I'm sure there's a reasonable explanation.
like the fact that our military is wholly dependent on GPS and real-time connected war fighting. Loss of satellites hurts us a *lot* more than them.

China constantly threatens Taiwain. They invaded India in the 60s. They supported north vietnam. They supported North Korea. They gave the tech for the nuke to North Korea and are currently helping Burma to get it. They currently pull the same garbage that the Cold war had earlier which is using proxies.
So, they answer is that direct invasions do not have to go on. Heck, America has not directly invaded another nation EXCEPT that invaded us, or where we were invited in. For example, Afghanistan attacked America. Iraq invaded Kuwait, so we in there with encouragement from them. In 'nam, we got pulled in by France because North Vietnam invaded the south. In South Korea, we supported the south after the north invaded them. We got pulled into WWII because we were attacked. etc. etc. etc. About the ONLY two military actions of the last century that was by us would be reagan's panama and grenada actions (both of which I was opposed to, just like W's re-stepping up Iraq).

the Chinese military seem far more rational than the US military at this time...
thats ok, they can have France....
HA! I just wasted some of your bandwidth with a frivolous sig!
You misspelled "nationalized".
China is positioning themselves for a hot war.
...is one interpretation. Another is that because they are way behind the us in terms of tech, both deployed and under development, they are trying to make up quality with quantity. And they are arming like mad, because they are way behind in the race.
HA! I just wasted some of your bandwidth with a frivolous sig!
Not News: China shoots down a satellite using ICBM scale hardware (the speculative fiction and barely, if at all, relevant details padding TFA not withstanding).
News: US shoots down a satellite using a missile built from off the shelf components,
News: launched from a fighter jet,
News: 25 years ago. OK, not strictly 'news' but darn sure puts perspective on China's 'accomplishment' as well as the DoD FUD poured over it to try to make it sound newsworthy.
No offense meant to the poster. It's good to keep track of what non-news the FUDmongers are aping from government propa^H^H^H^H^Hpress releases. The only real news here is what kind of verbal bilge the government is trying to get you to dance to.

Except for the fact that GPS satellites are not in LEO orbit. It would not affect the GPS constellation at all. It could affect future launches of GPS by preventing future launches. Most, but not all comm satellites are in higher orbits. Also with the same caveats on future launches.
Our founding fathers removed the guys in charge. Be American. Vote incumbents out.
The reference is this blog posting over at Foreign Policy which was posted back in March: http://shadow.foreignpolicy.com/blog/5630 The test was of a sub-orbital kill vehicle intercepting a sub-orbital target, both launched from ballistic missiles. There was no orbital debris generated and a satellite was not destroyed. This can be verified by looking at NASA's Orbital debris Quarterly Reports as well as the satellite catalog on Space Track: http://www.orbitaldebris.jsc.nasa.gov/newsletter/newsletter.html http://www.space-track.org/perl/login.pl However, because the same technology can be used for both hit-to-kill missile defense and hit-to-kill ASATs, the test can be seen as another test of China's ASAT capability, in the same way as the destruction of USA 193 (a satellite) by the US Aegis missile defense system

China and Taiwan just signed a treaty to further tie their economies together. Most observers see it as a first step towards a formal peace, and eventual reintegration, just as they did with Hong Kong. As far as the border skirmish with India, it lasted for exactly a month, and KIA was under two thousand. As far as who was at fault, you'll have to read the evidence for yourself.
As far as North Korea goes, they have been pretty adept at getting nuclear technology from others, probably including. The more modern centrifuges are from AQ Khan in Pakistan according to US intelligence, though he later denied it. They have nuclear tech from Russia, and even a bit from the US during the Clinton years. I doubt it shocks you that the Chinese and the Russians fought a proxy war against America on their own border. We'd do the same thing, if they had ever come near ours.
Heck, America has not directly invaded another nation EXCEPT that invaded us
That's an outright lie. http://en.wikipedia.org/wiki/Timeline_of_United_States_military_operations
Your history seems to be based on something you believe about America, rather than what America actually is.
Actually, I meant to add in for "the last 70 years", but missed it (called away to take care of a 3 y.o.) . You are correct about 1800's. BUT, If you look at the 1900's, you will see that other than reagan's little wars, all we had were skirmishes, not much different than what USSR, Russia, etc do.

99% of the posts that aren't forced to have one because they don't reply to anything just keep the "Re:" subject line that Slashdot fills in for them. Using them as a rhetorical device to split one part of your post from the rest is basically their main function.
The fact that China will continue their space based weapons, and more importantly, they will continue to purposely pollute space with their tests.

The satellite it's still there, you guys are holding it wrong.
In all the honesty, China as a nation resembles USSR a lot. It has a major nationality (han), and a boatload of "little brother" nationalities, all spread across largely autonomous regions.
So yes, it's a nation, but definitely not like most western nations such as Germany, UK, France et al. Those are ethnically very solid, with vast majority of population being of same or very similar ethnicity.
I'm sure there's a reasonable explanation.
Yeah, like China soon starting a very profitable space junk removal service at a global level?
Doesn't make sense to add more of their own junk though :)

I don't think any amount of stuff on LEO would prevent launching of military satellites to higher orbits, or even to LEO (they'd just have a short lifetime on LEO).
Ok, once we can move a nice little asteroid and break it into small pebbles covering LEO, then we perhaps could make the environment too hazardous for launches. But, alas, our puny technology can't do that yet. OTOH, at that point we'll probably also have the technology to clean up the orbit, even from ground (think of giant sharks with lasers in their heads, roaming the oceans and looking into the space, zapping space junk out of orbit).

"Any amount" as in amount that is small enough so that interaction between debris particles doesn't cause very rapid depletion, while still being large enough to pose more than 50% chance of collision with a rocket booster stage as it zips through LEO altitudes towards MEO or GEO.
Note: if there are gaps in debris field allowing higher probability of successful LEO penetration, that also counts as not being dense enough. And in this context, it's worth noting that while it would take only a dense enough band of debris orbiting above equator to prevent launches from equator, preventing launches from higher latitudes would require complete blanketing of the Earth, which requires something like 1-2 orders of magnitude more debris.
