Space Rocket History #50 – Blue Gemini – 1963

Posted on February 12, 2014 by spac9750

“Blue Gemini” was the tag name for an Air Force manned space flight program to develop rendezvous, docking, and transfer for military purposes, using Gemini-type spacecraft. The concept became firmer in June, when the Air Force Space Systems Division (SSD) began working on plans to use Gemini hardware as the first step in a new Air Force man-in-space program called Mods (Manned Orbital Development System), a kind of military space station with Gemini spacecraft as ferry vehicles…

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

This brings us to Project Gemini. Gemini started after Apollo had begun, in part to answer a crucial question for Apollo. Was rendezvous and docking in orbit a feasible basis for a manned lunar landing mission?
