Uses
Among other uses, the clandestine Corona program used Thor-Agenas from June 1959 until January 1968 to launch US military reconnaissance satellites operated by the CIA. During this program, Thor-Agena launch vehicles were used in 145 launch attempts now known to have been part of satellite surveillance programs.
Also, Alouette 1, Canada's first satellite, was launched on a Thor-Agena-B.
