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.
Gemini 12 (officially Gemini XII) [3] was a 1966 crewed spaceflight in NASA's Project Gemini.It was the 10th and final crewed Gemini flight (Gemini 1 and Gemini 2 were uncrewed missions), the 18th crewed American spaceflight, and the 26th spaceflight of all time, including X-15 flights over 100 kilometers (54 nmi).
The following table shows the approximate dates of the twelve astrological signs, along with the classical [9] and modern [10] rulerships of each sign. By definition, Aries starts at the First Point of Aries which is the location of the Sun at the March equinox .
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 ...
Agena may refer to: Keiko Agena (1973), an American actress; Beta Centauri, a star; RM-81 Agena, a rocket upper stage family developed by Lockheed, especially the Agena target vehicle used in preparation for the Apollo program lunar missions; AMD K10, a processor codenamed "Agena"
Thor-Agena was a series of orbital launch vehicles. [1] The launch vehicles used the Douglas-built Thor first stage and the Lockheed-built Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family.
