U.S. Considers Anti-Satellite Laser
SpaceAdmiral writes "The U.S. government wants to develop a ground-based weapon to shoot down enemy satellites in orbit. The laser will be much more powerful and sophisticated than a similar endeavor a decade ago. From the article: '... some Congressional Democrats and other experts fault the research as potential fuel for an antisatellite arms race that could ultimately hurt this nation more than others because the United States relies so heavily on military satellites, which aid navigation, reconnaissance and attack warning.'"
Far more likely it's to protect America's "intellectual property economy" when it's cheap enough for private individuals to launch their own satellites to disseminate information under any laws they see fit.

There are shills on slashdot. Apparently, I'm one of them.
It'll be ready when Kent gets back from the cleaners to finish mounting the optics.

Actually, if that happened, I would imagine that there would be an "arms race" to produce stealth satellites, and weaponized satellites that can take down antisatellite weapons.
Don't take life so seriously. No one makes it out alive.

Dr. Evil: What?

Dr. Evil: What did you call me?
Scott: Nothing.
Scott: [pretends to sneeze] Ripoff.
Dr. Evil: Bless you.
Dr. Evil: I will hold the world ransom unless you give me... ONE MILLION DOLLARS!
[UN members all start to laugh.]
Dr. Evil: Er, that is, unless you give me... ONE HUNDRED BILLION DOLLARS!
[UN members gasp!]
You can't handle the truth.
Nothing says 'Peace' like the United States blasting another country's satellite out of the sky. I can't see how doing so would help prevent attacks on the U.S. Perhaps the idea is to disable communications and espionage capabilities, but there are other, more conventional means of warfare, as ineffective as they may be.
The other theory, give countries warnings about removing satellites? Countries love ultimatums too. Don't get me wrong, I'm not saying that I'm against this (or for it, really) but I'm suggesting that perhaps the political and diplomatic repercussions might need to be investigated more thoroughly.
From a sci-fi point of view, its Spies Like Us all over again! Sounds interesting and technological to say the least.
And they said zombies weren't real!
WTF? What happened - the Iranians are now developing satellites? al-Qaeda? What a waste of money.
I've never tried, but I'd assume its relatively difficult to make satellites out of sticks and dirt.
And they said zombies weren't real!
Check out the story "Death Ray -- or Accounting Shift?" here: http://www.defensetech.org/
A mirror.
As the USA concetrates on the development of these so called lasers, al-Qaida and its affiliates will enter the USA through the porous southern and norther borders and do greater harm.
Folks, do not be suprised to hear in future that this project has corruption and greed behind it. Remember that the USA spent US$5.99 billion on the shuttle which was never value for money!
Devoloping this technology could ultimately come back to bite us. The US has more birds up there then anyone else does, and once we develop the technology, other countries will get it quickly after that. Sounds like it's time to start developing laser proof sats.

NSFWMilitarizing the space in near-earth orbit and creating a military highly dependant on satellites is just stupid. A few missles that blast millions of ball-bearings into to orbit, and the entire planet will be locked out of space for hundreds, or even thousands of years. High-altitude, high-endurance vehicles that can hover over a single area for long periods of time leave us far less vulnerable (we just need air-superiority), and don't make near-earth orbit a target. Unfortunately the current administration is crazy-arrogant and shortsighted.
Regarding your comment...it's a bit pointless to work on a defense measure for a military threat AFTER it has been deployed or its deployment is iminent. While it sure is popular to bash the US these days, I'm sure there is all kinds of research going on around the world to counter perceived threats that might seem silly now, but may become dead serious 10 years from now.
They've been doing it for the last 10 years.
An object in a stable orbit cannot be "shot down". Its not an aircraft.
You can destroy it but all that will happen is that the pieces will
spread out from the point of explosion/impact and eventually become
space junk that could cause problems from friendly satellites.
Hopefully the laser would only disable a satellite and not cause its
fuel tanks to detonate , since if they do then the US will simply
be causing problems for itself , its allies and all space farers in
the future.

It's kind of like in a real world fight - sure, you would love to bring a baseball bat into the fight but you don't because you don't want the other guy to bring one in either. Seems to me like it would make more sense not to have the technology at all. I have to admit though - the other day when I read that Isreal had launched a satellite - seemingly in response to the actions of Iran it all seemed too easy to do - made me wonder what regulates who gets to send one up in the first place.

This is a waste of money. Spend the cash you'd put into a ground based anti-satellite laser and instead do things that would measurably improve the security of the US against attack from vectors which matter in realistic terms. If we determine we really need to destroy a satellite, we already have specially designed anti-satellite missles.
Or... our 'enemies' could just start building reflective satellites, or even just carrying a big, reflective 'shield' underneath them. It could be something as simple as a big, inflatable mylar bag. I don't know how much heat a very reflective mirror would have to dissipate when being hit by a laser, but it obviously can be done, if the adaptive optics in the 'gun' don't burn out, and that's right freaking next to the output of the laser, instead of through 100+ miles of atmosphere and space. Actually, a big shield might work really well. Any sensors that need to see around the shield could retract back quickly upon detecting a really freaking bright light source.
Nothing says "unprofessional job" like wrinkles in your duct tape.
So, instead of thinking of a better way to defend OUR satellites, they are thinking of ways to obliterate THEIRS? WTF?! If any country stands to lose more from having their satellites blown our of orbit, it's the United States!
Don't get me wrong, I'm glad they are thinking of the most likely attack that will befall satellites, but the logical step after this is to design something that can divert this type of attack. If the US were to suddenly lose all satellite communications, we'd be in some serious doo-doo. It seems, at least to me, that the prudent course of action would be to make a DARPA type of contest for this technology, or at least focus more grant money in this area. (Granted, the result would probably be to wrap more tin-foil around the things.)
Umm, read some history. There's even a picture of one National Socialist German Labor Party nuke design.
Imperial Japan had nuclear bomb programs too.
Personally, I'm glad America got there first.
The Soviets took the easy route. They had some Useful Idiots steal the technology.
The Soviets had ASAT programs too. ASAT weaponry is old news, it's just that now they're using lasers rather than missiles. Heck, even that's not all that new, though making it work would be.
Don't you think the way for the US to really ensure its population's security would be to try to track down the arsenal of the former USSR?
Don't you think Putin ought to take nuclear security more seriously? The Russians built the damn things and they're not so poor that they can't deal with them if they want to, especially with high oil prices pouring hard currency into Russian state coffers.
My response to reading the article: duh!
Here are some recent articles on the developments in China. The US is not starting this race, but it'd be nice to keep up regardless.

The world is, a dangerous place. As with Sudan and Iran, the UN is no deterrent to aggression. Enlightened self-interest directs us to investigate these types of systems for the same reasons we investigate lethal pathogens. Surviving them requires understanding them even if we never intend to use them.

removing their capability to deliver precision guided munitions.
And therein lies your problem. If your enemy can't pin-point the military target, then their next best option is to target a large city. Way to go, that was smart. Instead of losing a missile silo, you lose 250,000 citizens.
All you'd need is a large rotating mirror and a tracking system, and you could vaporize a human targ -- er, I mean, Intellectual Property Thief from space!
"Ladies and gentlemen, my killbot features Lotus Notes and a machine gun. It is the finest available."
I think you are actually right on the money here.
The U.S. isn't really concerned about enemy spy satellites -- god knows our borders are so porous, you could just send a TV crew in and photograph almost anything you want, as long as they don't look Middle Eastern -- but navigation satellites are another matter.
The saving grace of the GPS system, from a U.S. military perspective, is that an enemy really can't depend on it; we can throw errors into it pretty much anywhere, anytime we want without having our equipment be affected (except all the guys using civilian GPS receivers because they haven't been issued real ones). I think there's a real concern that if there was a competing GPS-like system, that an enemy could use it to pilot a cruise missile at a U.S. target in such a way that we wouldn't get much warning.
Now, I think this is kind of a false threat: I think, given what I said earlier about our borders, that it's a whole lot easier to just drive a truck up to said U.S. target and blow it up than it would be to cobble together a homemade V-1 or V-2 with Galileo navigation, but apparently others disagree.
At any rate, any navigation system that provided GPS-like accuracy that wasn't within direct U.S. control would almost certainly necessitate the creation of a way to destroy it, or at least temporarily disable it in certain areas (if you de-orbited a satellite or two you might be able to make a hole in the system's coverage that would take a while for the operators to replace from spares).
Not that it would do any good against ICBMs, Chinese or otherwise, since they use astro- and inertial navigation systems anyway.
"Ladies and gentlemen, my killbot features Lotus Notes and a machine gun. It is the finest available."
This was basicly the logic behind the ABM treaty. It still holds good.
With our current terrorist enemy, I cannot see blinding any satellites would help. With potential enemies, most of them have nukers and likely would get very edgy blinded.
This is impossible. A laser beam is a very high frequency electromagnetic wave.
It is a electric field and a magnetic field moving together.
The breakdown voltage of air is about 2000V per millimeter.
With a powerfull laser in a lab, which is about fifty orders of magnitude too weak to do anything to a satellite, you can get sparks in mid air due to the air breaking down because of the high voltage of the electric part of the electromagnetic wave.
You cannot generate a laser beam powerfull enough to destroy a satellite from the ground. IF you tried you would just make a lot of plasma in the air above your laser. Focusing lots of little lasers on a satellite would require far more lasers than could be practically built.
I suspect these storys are planted in the media to worry unfriendly countrys, just like the star wars program that never had a chance of working or the rediculous story I saw in a newspaper a couple of years ago about missiles that can burrow into the ground and destroy a shelter 150feet down.
I also think it's a sad reflection on the state of slashdot that this story is up to 150 comments and I'm the first to point this out. I'm going to go and bash my head on a wall unitl I come to my senses and stop even reading alterslash.

From your SpaceDaily.com link above: "China will become the third nation after U.S. and Russia to possess an ASAT system." China can make arguments identical to yours about enlightened self-interest. They could make the same argument about WMDs -- and Saddam Hussein, Kim Jong Il, and the regime in Iran have all done just that. Deterrence, etc.

Q: What did the comedian say to the crowd?
A: If I knew, this joke would be funny.
The world DID NOT CHANGE after 9/11 because of 9/11. It changed because of people claiming it changed, and said people "protecting" us from boogeymen. First it was communists- now it is terrorists.
3,000 people died in the WTC attacks; twice as many Americans die from heart attacks in a month, and preventing their deaths doesn't require stripping people's civil liberties.
