Space Rocket History #61 – Gemini IV with James McDivitt and Edward White – America’s First Spacewalk – Part 2

For the first time Television coverage of the launch had an international audience, as the scene was broadcast to 12 European nations via Intelsat 1 aka the Early Bird satellite of episode 59. Heightened by the prospect of an EVA and the first use of the new Mission Control Center in Houston, interest in Gemini IV reached levels never again matched in the Gemini program…

Space Rocket History #60 – Gemini IV with James McDivitt and Edward White – Part 1

The success of Gus Grissom and John Young’s Gemini 3 flight paved the way for long duration space missions. The longest U.S. manned space flight to date was Gordon Cooper’s 34 hour Mercury flight. The Soviets, however, had four long duration flights to their credit, ranging from 70 to 119 hours. It was time for the US to attempt a long duration flight.

Space Rocket History #49 – Gemini Systems Design – 1962

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…

Space Rocket History #48 – Gemini Design – 1961

“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
