A few books that I whole-heartedly recommend:

- "Digital Apollo", a book about HCI, the tension between automation and human-in-the-loop, the history of systems engineering and minutae of each Apollo landing through those lenses. If you want a heavy dose of interesting, inspiring and thought-provoking HCI and embedded engineering lessons and anecdotes in context of the most thrilling examples possible you'll love this.

- "Sunburst and Luminary", the really quite charming and lively memoir by Apollo software engineer Don Eyles.

- "Apollo" by Cox and Murray, a go-to general history of the Apollo program that emphasizes program management and engineering far more than the astronauts.

This + the CuriousMarc videos and you'll feel spaceflight mini expert high, and be quite capable of maybe flying a landing in one of the emulators, actually understand the technical jargon in any of the Apollo landing videos or the Apollo 13 incident video, or appreciate some AGC source code.
