“I would like to reiterate once more that it is absolutely mandatory that we arrive at a definite mode decision within the next few weeks. . . . If we do not make a clear-cut decision on the mode very soon, our chances of accomplishing the first lunar expedition in this decade will fade away rapidly.” Wernher Von Braun June 7, 1962.

Langley’s brochure for the Golovin Committee described Lunar landers of varied sizes and payload capabilities. There were illustrations and data on a very small lander that was able to carry one man for 2 to 4 hours on the moon. There was an “economy” model that could two men for a 24-hour stay. The third model was called the “plush” module, it would carry two men for a 7-day stay on the moon. Weight estimates for the three craft, without fuel, were 580, 1,010, and 1,790 kilograms, respectively…

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…
