Space Rocket History #49 – Gemini Systems Design – 1962

Posted on February 6, 2014 by spac9750

On January 3 1962, “Gemini” became the official designation of the Mercury Mark II program. The name had been suggested by Alex Nagy of NASA Headquarters because the twin stars Castor and Pollux in constellation Gemini (the Twins) seemed to him to symbolize the program’s two-man crew, its rendezvous mission, and its relation to Mercury. Coincidentally, the astronomical symbol (II) for Gemini, the third constellation of the zodiac, corresponded neatly to the Mark II designation…

“The main trouble with the Mercury capsule was that most system components were in the pilot’s cabin; and often, to pack them in this very confined space, they had to be stacked like a layer cake and components of one system had to be scattered about the craft to use all available space. This arrangement generated a maze of interconnecting wires, tubing, and mechanical linkages. To replace one malfunctioning system, other systems had to be disturbed; and then, after the trouble had been corrected, the systems that had been disturbed as well as the malfunctioning system had to be checked out again.” James Chamberlin

Premiere Khrushchev was not willing to wait until Soyuz for another space first. Khrushchev believed, There could be no final victories in the race for space propaganda. He knew the US was working on project Gemini which would carry two astronauts in 1965. So, as a means to upstage the US, Khrushchev ordered Chief Designer Korolev to fit three cosmonauts into the Voskhod spacecraft that was designed for two…
