I often wonder about the electronics of 1969 and what was done to mitigate radiation problems. For instance, the type of memory was called core rope memory https://en.wikipedia.org/wiki/Apollo_Guidance_Computer https://en.wikipedia.org/wiki/Apollo_Guidance_Computer For anyone interested, XPrize winner Karsten Becker talks to popular youtube blogger David Jones about radiation, extreme heat & cold in space and specifically talks about bit flip and how electronic parts are sourced for such endeavors. https://www.youtube.com/watch?v=7JwNmdV2QPs https://www.youtube.com/watch?v=7JwNmdV2QPs Interesting to me was the "paper work" cited in the interview for space harden components. In other words, people are concerned with stuff falling back to Earth (wouldn't it burn up?) or used for not so friendly purposes (war).
