The result was the Atlas LV-3 Agena D, a standardized version of the Atlas D core and Agena B which would be the same on every launch (at least as far as the Atlas was concerned, Agena Ds often still had customized setups, especially for DoD payloads). The Agena D first flew in July 1963, starting a series of 15 successful launches for NASA and ...
The Agena-D was used to launch KH-7 GAMBIT and KH-8 Gambit 3 reconnaissance satellites, three Mariner probes to Venus and the two Mariner space probes to Mars. Thor-Agena flew for the last time in 1972 when it launched a KH-4B satellite. The last Atlas-Agena used an Agena D stage atop a refurbished Atlas F missile to launch Seasat in 1978 ...
The Atlas-Agena and Atlas-Centaur satellite launch vehicles were also derived directly from the original Atlas. The Atlas-Centaur was evolved into the Atlas II, various models of which were launched 63 times between 1991 and 2004.
The name 'Agena' derived from the star Beta Centauri, also known as Agena. The combined spacecraft was a 26-foot (7.92 m)-long cylinder with a diameter of 5 feet (1.52 m), placed into low Earth orbit with the Atlas-Agena launch vehicle.
The currently operational variant, Atlas V, has flown 81 consecutive missions without failure between October 2007 and January 2022. Due to the size of the list, it has been split by decade: List of Atlas launches (1957–1959) List of Atlas launches (1960–1969) List of Atlas launches (1970–1979) List of Atlas launches (1980–1989)

A KH-7 launch on Atlas-Agena.. BYEMAN codenamed GAMBIT, the KH-7 (Air Force Program 206) was a reconnaissance satellite used by the United States from July 1963 to June 1967. . Like the older CORONA system, it acquired imagery intelligence by taking photographs and returning the undeveloped film to ea
Later Gemini flights were supported by seven uncrewed launches of the Agena Target Vehicle on the Atlas-Agena from LC-14, to develop rendezvous and docking, critical for Apollo. Two of the Atlas-Agena vehicles failed to reach orbit on Gemini 6 and Gemini 9, and a mis-rigging of the nosecone on a third caused it to fail to eject in orbit ...
