US to Shoot Down Broken Spy Satellite

WASHINGTON (Feb. 14) - President Bush decided to make a first-of-its-kind attempt to use a missile to bring down a broken U.S. spy satellite because of the potential danger to people from its rocket fuel, officials said Thursday.
Deputy National Security Adviser James Jeffries, briefing reporters at the Pentagon, did not say when the attempted intercept would be conducted, but the satellite is expected to hit Earth during the first week of March.
"This is all about trying to reduce the danger to human beings," Jeffries said.
Gen. James Cartwright, vice chairman of the Joint Chiefs of Staff, said at the same briefing that the "window of opportunity" for such a shootdown, presumably to be launched from a Navy ship, will open in the next three or four days and last for seven or eight days. He did not say whether the Pentagon has decided on an exact launch date....

If its successful, it would be an excellent source of data to use on future weapons

sounds to me like a message for the chinese.

lol, its a simple satellite! ..wait, maybe not...
maybe time for a new topic called "a satellite nuclear thread" *g*

Actually the Chinese already shot down a satellite, they did it a year or two ago. They also blinded one of our satellites using a earth based laser around the same time line.
As for shooting it down, I think it has more to do with the info and technology on the satellite rather than dangerous fuels. I think the fuel is just used as a public excuse. JMHO..

i know. it may be our way of saying..."well yah, that was nice...but look at this."
but then, they did theirs with "freekin laser beams" didn't they?
-
....and what are they planning to do with all debre left in space? IIRC US was *****ing at China for shooting down their weather satellite....

I smell a chance to test that fancy new RAILGUN ;)
-
Fuel or classified tech? Better not make a mess up there..

Yeah... because the Chinese have no sense of history.
The U.S. has done this before. So has Russia. It's practically routine.

i did not know that.

I remember reading about an F-15 shooting down a satellite before

yeah yeah , the chinese are 30 years ahead of the US in space stuff, or was that the russians that are 30 years ahead.

I wonder if the explosion will be visible from the ground.

Not much visible flash bang eye candy.. The warhead will be kinetic, not chemical.

A 1-piece kinetic shot with an untested solution on a possibly jittery target, impact near end of boost phase... Target impact is at 275km altitude..

lol poor scientists..
"The first and only ASM-135A launch against an actual target satellite took place on September 13, 1985, when F-15A 77-0084 of the 6512th Test Squadron stationed at Edwards AFB took off from Vandenberg AFB and zoom-climbed up to 80,000 feet and then launched the ASAT against the Solwind P78-1, a gamma ray spectroscopy satellite that had been launched in February of 1979. Both the first and second stages fired successfully, and the miniature kinetic kill vehicle separated and homed in on the satellite, destroying it upon impact.
The test was a success in that it demonstrated that the basic concept was feasible. However, it enraged arms control advocates, who saw the test as a violation of a joint US/Soviet treaty forbidding the development and testing of antisatellite weapons. .Solar scientists were not happy about the test either, since although the Solwind P78-1 that was killed had officially completed its mission, it was still sending back useful data "

318th FIS out of McChord AFB Wash was trained and capable of delivering ASAT.
IIRC they were one of only two F15 squadrons tasked with combat delivery of ASAT. The F15 had to climb to 80,000 feet to deliver but the ASAT capability was scrapped by congress in 1988.
I used to love watching the F15s buzz out of McChord when I was a kid.
Beautiful tail insignia for the Green Dragons 318th FIS. See link:

Larger question.
why did it take so long to come to this decision.
The solution seems pretty obvious from the start.
Wonder if it will put aon a really cool lightshow

Thats what I was wondering, I'd love to see that.

ive always wondered what would happen if you threw a bag of rocks straight down at the earth from the space shuttle.
hmmmm.....

Id like to try a bowling ball over iran
especially if the core is plutonium
BOOOOM

The same thing would happen as does to lots of bigger rocks, daily.. :)
Dred keep in mind this is a school bus sized secret sat...

cool! we could have meteoric pyrotechicians who could go into space and launch meteorites that would burn in over the superbowl.
different types of minerals for different colors. now that would be wayyyy cool.
:D
-
:lol
Some material or other that'd end up as a fine mist at the right altitude, sensible to electricity, so that you'd get different colors depending on the applied current.. instant sky-wide strobe effects :cool:
-
now we're talkin!
:aok
-
i wonder what the viewing area would be for something like that.
-
Something like auroras I guess.. Epileptics beware!

As has been alluded to, you really have to wonder if this isn't a contrived anti-satellite test. What're the Chinese gonna do, put more lead in the toy paint?

Oops, sorry bout that, we're you guys still using that old thing?
:lol

It'd be effective if the missile hit and didn't leave any debris. It'd mean the US can roll out a missile from any suitable navy platform and take down sats up to at least 275km.
Then again it could just mean another arms race of sorts.

The last time we had an arms race it led to the end of the Soviet Empire. Of course if China lost, they'd just go back to being China.

You know since this is a Spy satellite, wouldn't you think it was carrying nuclear weapons on board? I mean if it was such a threat that it might crash in an urban area and they new they could blow it up with ease, wouldn't they just blow it up right away?
If you think about it though, satellites have falling back into earth, but burnt up on their way down. Wouldn't this satellite do the the same thing? But imagine a satellite with advance technology and was carrying nuclear weapons on board and it crashed into an urban area and a nuke exploded, there's going to be alot of explaining from the U.S. government.
So if you think about it, they're taking days to just destroy it b/c they want to know if they shoot it down from a certain area on earth and destroyed it over the ocean would anyone see the nuclear explosion. Also maybe they want to blow it up, so it doesn't fall the sky and cause a nuclear explosion or crash in the oceans by Russia, China, or some other country and have their military discover nuclear weapons that are still active. I bet this is a major coverup. Bull crap its a toxic fuel. If the thing catches on fire while rentering Earth couldn't the fires cause the fuel to explode miles above our heads?
Cover up :noid
-
No offense, but nukes? That's as good as any other theory pulled out of nowhere.
The sat has 1000lbs of frozen hydrazine. That'd already be enough to warrant making sure it breaks up enough to burnout before reaching the ground by sending a missile after it.
It's more likely to have bits of tech they don't want in anyone's hands.
You can't blow it up right away or it will leave debris for something like a century or two, or more. Eventualy there is enough debris from debris smashing into healthy sats, that you've got an out of control positive feedback. End result is no more space launches in Earth orbit because of the cloud of high speed particles everywhere.

Well we keep bragging that we have missles accurate enough to put through a window.
A school bus should present no problem then

according to this source any debris left won't be around long...
Gen Cartwright said there was no parallel with Beijing's actions as the Chinese satellite had been much further out from Earth, meaning its debris could be floating round for decades, endangering spacecraft.

Theres actually alot of debris floating around in space orbiting the Earth, the Air Force even has a division who's job it is to monitor all the debris floating around up there.

You are missing the whole point..We are much further advanced than them, however they showed that simple thinking and a low tech approach can counter just about any hi tech advantage we may have.
The first one they did with a rocket.. Pretty much the low tech slam into it approach.
The second a little more high tech, they used a high powered laser beam to temporarily blind one of our spy satellites. It was said at the time they could likely fully disable a satellite with the same approach.
Our continuing dependence on high tech solutions will eventually bite us in the ass. Sure I love all the technology that comes from all these cool military gadgets.. Yet I think our military seems to be trying to rely too much on high tech for it's future.
What good will unmanned drones be if they have no satellite to guide them? Same goes for anything dependant on GPS.. ect.. ect..

we need to build cylons, then we'll be safe....

Skynet is the answer... then we'll have nothing to worry about...

half of China's exports go to the US, again i ask, why would they attack their best customer?

http://www.cnn.com/2008/TECH/space/02/14/spy.satellite/index.html
"In January 2007, China used a land-based missile to destroy a 2,200-pound satellite that was orbiting 528 miles above Earth.
But the impact left more than 150,000 pieces of debris floating above Earth, NASA estimates. The space agency characterizes nearly 2,600 pieces as "large," meaning greater than 4 inches across, which pose a potential threat to satellites and spacecraft.
China is responsible for 42 percent of all satellite debris in orbit as of January 1, most of it from that Fengyun-C meteorological satellite.
NASA has called it the worst satellite breakup in history."

Far more then just the arms race which lead to the end of the Soviet Union. Just one part of it and debatable whether it was a significant factor or not.

No... NASA is stagnant because of red tape. If China catches up it's not because of low tech but because there won't be any beating around the bush, just like there was no *****footing on the way to the Long March rocket BBQs... That's it in brief. Read up on facts before you make claims like that.

Apparently Russia is upset about us shooting this satellite down, saying that were using it as an excuse to test out missile defense system for shooting down other countries satellite's.
