I was disappointed to see some lack of enginnering details and a lot romance in it. I was expectiong something like the Martian with much more "realistic" technical discussions.
Anyway I started to think about the technical problems they needed to solve/manage, and the more I think the more I got pushed in the "never happened" bucket.
When an Italian like me, with spanish money, discovered America we returned to that land more and more. Do they never went back to the moon? Not even once?
The US went to the moon on military spending during the cold war. Beating the Russians was a strong motivator to spend the money necessary - about $200 billion USD equivalent in today's money. The methods used were also not designed to be replicated in a long-term way - that is, the goal was to prove we could go to the moon, not build the infrastructure and technology necessary to go to the moon on an ongoing basis. Once the goal was met, the US congress didn't see much reason to continue to spend money to go to the moon (been there, done that), and the funding was cut.
One should note that we landed on the moon not once, but six times. Apollo 11 through 17, not counting Apollo 13. Apollo Missions 18-20 were planned but cut due to budgets.
All of the space work we've been doing ever since (Shuttle, various launch platforms, etc), have been to build that infrastructure to put us back in space on a permanent, affordable, basis. For instance, we have an international space station which has been continuously occupied since 2000 which shows how much we've learned about actually living in space, as opposed to a week long visit to the moon.
In my heart I believe a man was walking on the moon, but my brain is still not 100% convinced. It seems technically impossible. Please help.
PPS: Any good book I can read on this topic?
If you can get a copy of the miniseries 'From the Earth to the Moon', that would be a good set to watch video-wise.
There are lots of good books out there documenting various parts of the entire US space program. I guess it really depends on what parts you are interested in.
