Comparison of NASA Mercury, Gemini, Apollo, and Space Shuttle spacecraft with their launch vehicles. This is a list of NASA missions, both crewed and robotic, since the establishment of NASA in 1957. There are over 80 currently active science missions. [1]
Project Gemini (IPA: / ˈ dʒ ɛ m ɪ n i /) was the second United States human spaceflight program to fly. Conducted after the first American crewed space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966.
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 Gemini astronauts were sixteen pilots who flew in Project Gemini, NASA's second human spaceflight program, between projects Mercury and Apollo. Carrying two astronauts at a time, a senior command pilot and a junior pilot, the Gemini spacecraft was used for ten crewed missions. Four of the sixteen astronauts flew twice.
Advanced Gemini was a series of proposals that would have extended the Gemini program by the addition of various missions, including crewed low Earth orbit, circumlunar and lunar landing missions. Gemini was the second crewed spaceflight program operated by NASA, and consisted of a two-seat spacecraft capable of maneuvering in orbit, docking ...
Gemini 8 (officially Gemini VIII) [2] was the sixth crewed spaceflight in NASA's Gemini program. It was launched on March 16, 1966, and was the 14th crewed American flight and the 22nd crewed spaceflight overall.
Tracking vehicles in low Earth orbits (LEO) is quite different from tracking deep space missions. Deep space missions are visible for long periods of time from a large portion of the Earth's surface, and so require few stations (the DSN uses only three, as of February 20, 2010). These few stations, however, require the use of huge antennas and ...
Gemini 5 (officially Gemini V) [3] was a 1965 crewed spaceflight in NASA's Project Gemini. It was the third crewed Gemini flight, the eleventh crewed American spaceflight (including two X-15 flights above 100 kilometers (54 nmi)), and the nineteenth human spaceflight of all time.
