…From the information they gathered on the existing technical problems, Disher and Tischler concluded that prospects were only one in ten that Apollo would land on the moon before the end of the decade….
“The contractor role in Houston was not very firm. Frankly, they didn’t want us. There were two things against us down there. Number one, it was a Headquarters contract, and it was decreed that the Space Centers shall use GE for certain things; and number two they considered us (meaning GE) to be Headquarters spies.” Edward S. Miller of General Electric.
During 1962, NASA faced three major tasks: first the mode selection and its defense (covered in episodes 106-109), second keeping North American moving on the command and service modules (covered in episode 110) and third finding a contractor to develop the separate landing vehicle required by that approach. Which we will cover today in episode 111.
The Apollo contract specified a shirt-sleeve environment. For this reason, North American was told not to include in its design a hatch that opened by explosives, like Mercury’s. An accidentally blown hatch in space would cause an instant vacuum and certain death for an astronaunt not wearing his pressure suit.
After viewing the Apollo spaceport being built in Florida, President Kennedy flew on to Huntsville, Alabama. There, during a tour of Marshall and a briefing on the Saturn V and the lunar-rendezvous mission by von Braun, Jerome Wiesner interrupted Von Braun in front of reporters, saying, “No, that’s no good.” Webb immediately defended von Braun and lunar-orbit rendezvous. The adversaries engaged in a heated exchange until the President stopped them, stating that the matter was still subject to final review.
“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…
The mode that Apollo would use to land on the moon was the most studied, analyzed, and debated decision made for the lunar landing program. There were four main choices Direct-ascent, Earth-Orbit Rendezvous, Lunar-Orbit Rendezvous, and Lunar Surface Rendezvous.
