Left: What you can see from a a height of about three, or four storeys. Right: Roughly what a current U.S. Keyhole satellite can reportedly see from Earth orbit.[/caption]
I ended my post on the Russian Search engine Yandex with a flip comment, hoping satellites hadn't learned how to lip-read. Had to look that up.
According to available information on current U.S. spy technology, the answer is still no, but they're coming close. The Kennan “Keyhole-class” satellites are verging on 30-year-old technology. They're basically Hubble telescopes pointed at Earth, or to put it another way, giant digital cameras. They reportedly have a resolution of five to six inches, That means each pixel in one of their digital black and white images represents five to six inches. That was the state-of-the-military-art, back in 2001, and is still supposed to be today.
