The sign accompanying the Corona film return capsule. It reads
Developed by the U.S. Air Force and the Central Intelligence Agency, Corona photoreconnaissance
satellites were designed mainly to obtain images of the Soviet Union that
manned aircraft could not. The film in a Corona camera was reeled onto a spool
in a capsule like this one, which then separated from the satellite and
reentered Earth's atmosphere over the Pacific Ocean. The capsule deployed a
parachute, which enabled an Air Force airplane to retrieve it by snagging it in
mid-air. General Electric manufactured the capsules.
From 1960 to 1972, more than 120 successful Corona missions provided invaluable
intelligence on the Soviet Union and other nations. This capsule was recovered
on May 25, 1972, at the end of the last Corona mission. Modern
photoreconnaissance satellites return their images electronically.
