How the Government Controls Sensitive Satellite Data,
During the Cold War, on the vast, barren flatland around Area 51's dried-up Groom Lake, the military developed a stealth spy plane code-named Project Oxcart. Project personnel were sworn to secrecy, but still, US officials worried that the Soviets would find out what they were up to. With good reason: Up above, USSR satellites were ready to spy with their on-board cameras. While Area 51 employees couldn't stop these satellites from swinging by, they did come up with a low-tech solution: moving the classified planes into sheds when they knew the satellites would pass over.
Today, that's not a feasible stealth solution. Earth orbit doesn’t just host a few Soviet spysats: More than a thousand working orbiters are out there, hundreds of those equipped with Earth-observing cameras. They are American, European, African, South American, Japanese, Indian, Chinese, Russian. And nothing stops many of them from taking pictures of supersecret areas.
But the government has other ways of restricting information. The feds can limit how good commercially available images can be when taken by US companies. And it can issue a directive barring imaging over a given location. The law regulating that imaging, though, was first passed before satellite imaging really existed as an industry. And according to insiders, it’s been keeping satellites down—even as thousands more of them are set to launch in the next decade.
