Corona, using satellites with cameras instead of planes. The film was returned to the Earth in capsules called film buckets, designed to be captured by aircaft while descending on a parachute. After that, the cameras were useless. This is the inside of the film bucket:
I took this in the National Air and Space Museum's Steven F. Udvar-Hazy Center museum, in the space hangar. Inconveniently for photographers, the ceiling in that hangar is painted black, and some displays like this one are in plexiglass cases.
