Budget Issues Force Spy Satellites Into The Open
Korsair25 points out this article about a U.S. spy satellite program. "Quote: 'Over the decades, spying from space has always earned super-secret status. They are the black projects, fulfilling dark tasks and often bankrolled by blank check.' It also talks about some of the technology used to disguise or camouflage some of the operational satellites."
Apparently most of the governments secret high-optical resolution sattelites were curiously locked in geo-synchronous orbits
It's a nice idea, but rather pointless -- geosynchronous orbits are sufficiently expensive to reach, and would require sufficiently higher resolution optics, that it would probably be cheaper to launch an entire fleet of LEO satellites in such a manner that your target was always visible at the desired resolution.
