The Agena Target Vehicle (/ ə ˈ dʒ iː n ə /; ATV), also known as Gemini-Agena Target Vehicle (GATV), was an uncrewed spacecraft used by NASA during its Gemini program to develop and practice orbital space rendezvous and docking techniques, and to perform large orbital changes, in preparation for the Apollo program lunar missions.

The first Agena-D launch was of KH-4 #7 on June 28, 1963, and a total of 269 Agena-Ds were launched. 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 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 launched perfectly for the second time, after problems had occurred with the targets for Gemini 6 and 9. Gemini 10 followed 100 minutes later and entered a 86.3-by-145.2-nautical-mile (159.9 by 268.9 km) orbit. They were 970 nautical miles (1,800 km) behind the Agena. Two anomalous events occurred during the launch.
Agena 1022 VAFB, LC-75-3-4 Discoverer 1: Reconnaissance: LEO Failure Maiden flight of Thor-Agena A. Agena telemetry lost at T+730 seconds. Fate of the payload unknown, but generally presumed to have impacted somewhere in Antarctica. 13 April 1959 21:18:39 Thor DM-18 Agena-A Thor 170 Agena 1018 VAFB LC-75-3-4 Discoverer 2: Reconnaissance LEO Success
Thor-Agena B. Thor-Agena B (Thor-DM21 Agena-B or Thor-SLV2 Agena-B) was used for 44 launches between 26 October 1960 and 15 May 1966 [5] Includes a variant with Solid Rocket Boosters (TAT Agena-B or Thor-SLV2A Agena-B) [6] First successful launch: 12 November 1960 with Discoverer 17; Last launch: 15 May 1966 with Nimbus 2
GLV-10 12565 SC10 Young: Collins: 18–21 July 1966 22:20 UTC 02d 22h 46m 39s First use of the Agena Target Vehicle's propulsion systems. The spacecraft also rendezvoused with the Agena Target Vehicle from Gemini VIII. Collins had 49 minutes of EVA standing in the hatch and 39 minutes of EVA to retrieve experiments from the Agena. 43 orbits ...
Forty-three launches took place from 1966-72 with two complete failures and one partial. [2] [3] [5] [6]The launch of a KH-4A photo reconnaissance satellite on May 9, 1967, malfunctioned when the Thor's first stage failed to cut off on schedule and continued burning until LOX depletion, thus putting the satellite into an incorrect orbit that seriously reduced its image quality.
