What's the benefit from using an off shore platform against building them on the beach and using pipes for cooling?

Artemis 2 Coming Home

Watching the Artemis II live feed and watching the earth getting bigger by the minute and listening to the radio communication is breathtaking, and every bit fits perfectly to everything I read about Apollo. Anyone interested should read "How Apollo flew to the moon" by W. David Woods (ISBN978-0-387-71675-6). In my opinion the best and most detailed report of the procedures, technology and processes of the moon landings.

Just spend an hour outsite (Northern Germany, 01:00 MET). Unfortunately nothing to report, neither visual nor on camera. Maybe I just went to late and missed the show. I hope you habe more luck in Canada and the US!

Depending how deep you want to dive into this rabbit-hole:

-How Apollo flew to the Moon: https://amzn.eu/d/1QtsN1D Covers in my opinion all aspects of the Apollo/Saturn programme, including design, technology, procedures and a lot of history as well. A must read if you are interested in such things

-Moon Lander https://amzn.eu/d/bI3wpt7 Memoire of Thomas Kelly the chief engineer for the Lunar Lander. Gives great insights of the technical and management challenges while desiging the first "true" spaceship. Highly recommendet!

-Digital Apollo: https://amzn.eu/d/0KigTU9 Focuses on software development (actually an afterthought to hardware development) for the Command Module and the Moon Lander and on the important aspect how much controll should be given to the astronauts against automatic systems. Includes a very detailed analysis of the software alarms that almost compromised the first moon landing.

-Failure Is Not An Option: https://amzn.eu/d/ix6CWnq The memoir of the Gene Kranz, the tough, no bullshit flight controller pictured in the Apollo 13 movie. Kranz was a key player in the manned space program for decades. Here we learn that almost each moon mission had critical moments and had to be saved by the teams at mission controll and the astronauts.

Other interesting books: -Moon Launch: https://amzn.eu/d/1Z6U5f6 on Saturn Apollo Launch Operations -Sunburst and Apollo: https://amzn.eu/d/2ms3IW8 a personal memoire of one of the software designers for the LM computer

Hope there is something interesting for you in the list.

Thats the manual for an older configuration, not the one that flew to the moon.The CM hatch has the pre Apollo 1 fire design, and the booster is a Saturn 1B, not a Saturn 5. Does anybody know if something like this ist available for later configurations?

I can not recommend this enough, a must have if you like Escher's Art and are in weird geometric stuff.

Beware of "online QR code services", all of them insert some spam redirectons in the QR code. After trying a dozen founds from Google, I finally found a decent one from a german university.

Nice reference to the Musical Youth Song of 1982!

The most interesting thing is the Force/Displacement curve. It shows some plastic deformation even after the breaking point, which is unusual for „hard“ Materials. May this just be some gloryfied Epoxy with wood as filler?
