The classified military satellite systems code-named CORONA, ARGON, and LANYARD acquired photographic images from space and returned the film to Earth for processing and analysis. Satellite imagery from the Corona project, a Cold War spy program that acquired military intelligence about the Soviet Union for the US, is proving useful in ways its creators could have never imagined—including for archaeologists. More than 140 Corona satellites have been spying on the Soviet Union for 13 years. This program included several types of satellite which used a different photographic method.

And while many photographs are unusable due to cloud cover, atmospheric conditions, or other technical difficulties, much remains to be learned from Corona’s historic archive. Because the perspective of the satellite distorts spacial accuracy of the terrain, images require orthorectification before geographic features can be seen in their true position. The front camera was tilted 15° forward, and the rear camera tilted 15° aft, so that a stereoscopic image could be obtained. The aft-looking camera malfunctioned after the recovery of bucket 1. + '
