"The CORONA program was a series of American strategic reconnaissance satellites produced and operated by the Central Intelligence Agency "
"The CORONA satellites were designated KH-1, KH-2, KH-3, KH-4, KH-4A and KH-4B. KH stood for "Key Hole" or "Keyhole" (Code number 1010), with the name being an analogy to the act of spying into a person's room by peering through their door's keyhole. The incrementing number indicated changes in the surveillance instrumentation, such as the change from single-panoramic to double-panoramic cameras. "
I don't think these satellites are still up there though.
