An Internet denizen asks:
Q: How were we able to put a man on the moon with the level of technology that was available in 1969?
The answer? By spending a crap ton of money over ten years, peaking at 5% of the federal budget. And by relying as much at possible on already proven technology, which isn’t as “high-tech” as you think (more on that below).
Q: Did NASA have advanced technologies that were just not made public?
Very little. They developed the advanced technologies they needed, and except where they were borrowing from the military, they then made them public. NASA’s primary job, after all, is to promote and nurture the American aerospace industry.
Here are a few examples of how the technology came to be:
- Back in 1961, NASA knew it would need a big moon rocket, but they didn’t know how big or have a design for it. They knew, however, that back in 1955, Rocketdyne had started work on the granddaddy of rocket engines for the Air Force. The first attempt (the E-1) had been a dead end, but the second try (the F-1) had been successfully fired in 1957—the year before NASA was founded. The Air Force had abandoned the engine, but NASA paid Rocketdyne to continue development, and the engine was improved continually throughout the Apollo program, including thrust and reliability upgrades from one mission to another. For all that, the F-1 was in many ways a crude engine by today’s standards. In particular, it required hundreds of difficult, manual welds in refractory metal, which all had to be perfect. Today, the same engine could be formed in three (principle) pieces and welded together by robots, but back then, it was all done by hand.
