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.

The Titan II GLV (Gemini Launch Vehicle) or Gemini-Titan II was an American expendable launch system derived from the Titan II missile, which was used to launch twelve Gemini missions for NASA between 1964 and 1966.

Film review of the Titan II ICBM launches found at least seven other instances of post-staging tank ruptures, most likely caused by flying debris, second stage engine exhaust, or structural bending. NASA finally decided that this phenomenon did not pose any safety risk to the astronauts and took no corrective action.

“双子座”（Gemini）这个名称源于所用飞船能容纳两人，而Gemini这个词在拉丁语中意思是双胞胎。 双子座飞船与水星飞船最大的不同是，水星飞船将除制动发动机外的所有设备都放在飞船中，仅于宇航员一个舱门之隔。

2024年12月13日 · The Gemini program was designed as a bridge between the Mercury and Apollo programs, primarily to test equipment and mission procedures in Earth orbit and to train astronauts and ground crews for future Apollo missions.

Gemini was the second phase in the United States space program'slarger goal of "landing a man on the Moon and returning him safely to the Earth" before the end of the 1960s, as proposed by president John F. Kennedy.

2024年10月23日 · Yet, Gemini carried American astronauts into space in pairs, earning the approbation of the public, and the praise of the astronauts themselves. They flew in a vehicle that allowed them to learn how to fly in space, how to achieve formation with other vehicles, and how to work outside their spaceships.

2024年2月21日 · The eight stages are; pre-launch, lift-off, boost and staging, separation and Insertion, prepare-to-go to retrograde, retrograde, re-entry, and abort. Telemetry guidance, landing and post-landing are related to but not part of the Sequence System.

2024年12月30日 · The Gemini program was chiefly designed to test the ability of astronauts to maneuver their spacecraft by means of manual control. The Gemini series, directed by the National Aeronautics and Space Administration (NASA), helped to develop the techniques for orbital rendezvous and docking with a target vehicle, procedures that were vital to the ...

2021年11月12日 · The Gemini XII spacecraft was launched on November 11, 1966, and all launch vehicle systems performed nominally during powered flight. However, the first stage oxidizer tank ruptured during staging, similar to what happened during Gemini X's launch.
