I have heard its a couple of inches from rumors working in Defense - but it is highly classified information.

I hear they can have resolutions of around 1 foot. That doesn't mean reading writing on things one foot across, that means that it can see a 1 foot object.

The talk about reading license plates or text on a novel are just wild ridiculous rumors. For one, license plates are mounted vertically on a car so how would a satellite (that takes pictures from above) be able to see it?

From what I've heard the newer US military spy satellites are very similar to the Hubble space telescope. They're still subject to atmospheric distorion.

on the last west wing, they hinted that we have a military owned Space Shuttle that we've never seen. wonder if that's true...

Uhmmm, have you ever seen a Space Shuttle launch?
They're kinda hard to hide.

where would it blast off from? not Florida, people would notice, then know about it
it would have to be a pretty isolated location, and the russians/whoever (countries with detection capability) would have to keep quiet about it

Well I assume the LoD is sufficent to get wank worthy photographs of topless women on beaches, otherwise WTF is the point of building the thing in the first place?

All I can say is that half of the birds that go up never work, but the ones that do would surprise you. Your tax dollars at work.

The earth is not flat my friend. If in a certain range in its GO, the sat can can very good angled shots.....

The earth has an atmosphere my friend. Are they *trying* to photograph as much haze as possible or do you think they'd rather get a good shot?

Hell, if I can get my Fuji to take a nice picture, I bet theirs can do the same [/illogical nonsense]

Mr President:

Hello, this is Captain Roberts at SATCOM. Yes, I'm doing fine sir. We were calling you to let you know that your fly was down. Feel free to ask the VP to sheild it with the football. No problem sir.

Take a picture of something far out on the horizon and see how much detail you capture.

Grapefruit can be distinguished for oranges, size and color.

On Mars rocks down to about 6 feet can be catalouged..

There was a spy sattelite launched in the late 70's called "big bird" in the international book. It had the same focal length of the hubble telescope. That was in the 70's, consider what they have today.

The focal length will not be the same, for obvious reasons. Things the HST photographs are much farther away.

Huh? The focal length of any telescope is fixed by the length of the telescope and the number of mirrors used to extend the focal length. The principal focal length is simply the measurement from the first lens to the reception device (http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/foclen.html). The HST and the spy satellite from the 70's had nearly the same dimensions, I'm sure the mirror and element spacing would be different for the distances being looked at but the magnification power of the two devices should be close to the same.

I see what you're saying.

NASA gets good stuff, but the CIA gets the BEST stuff.

Just wait until there's a government leak and all the satellite nudie pictures the CIA takes get put up on the web...

If they were to do something like that, they could launch it from Vandenberg at night and say it was a missle test.

Or they could launch it from some remote island in the ocean somewhere.

Got an uncle who is former air force, his entire job (as I was told at least) was developing algorithms to correct for atmospheric distortion.
