  skos:definition """ARGON was a photo-reconnaissance satellite that was operation
between 1960-1972. The images were used to produce maps and
charts for the Department of Defense and other Federal
Government mapping programs.

President Clinton signed an Executive Order on 24 February 1995,
directing the declassification of intelligence imagery acquired
by the first generation of United States photo-reconnaissance
satellites, including the systems code-named CORONA, ARGON and
LANYARD.
