That's interesting. Do you have source(s) for that? I'm not a 'the Moon landings were faked' person, but how does this reconcile with manned Moon missions? [Edit] So I don't have to add another comment: My first thought was, 'oh shit, how long before someone hacks one of these and repurposes it?'

Here is a NASA booklet on the topic of radiation and manned spaceflight: https://www.nasa.gov/pdf/284273main_Radiation_HS_Mod1.pdf https://www.nasa.gov/pdf/284273main_Radiation_HS_Mod1.pdf

Apparently, the Apollo astronauts had a 43% mortality rate from cardiovascular disease, which the research quoted in this article attributes to radiation.

Here's a NASA technical note specifically about Apollo mission radiation, in Table 1 you can find the radiation measured for each mission. Then again, no major solar flares happened during the missions. In table 2, the rules that were prepared on how to react to these events can be found: https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf

The Apollo astronauts a) were inside a spaceship, not performing an EVA; and b) passed through the Van Allen belts pretty quickly; and c) the Apollo trajectory was actually optimized to expose astronauts to the least amount of radiation possible. This is a pretty good discussion: https://www.popsci.com/blog-network/vintage-space/apollo-rocketed-through-van-allen-belts#page-3 https://www.popsci.com/blog-network/vintage-space/apollo-roc... Unfortunately the references I have for the “one hour” claim (which, to be fair, has a lot of uncertainty associated with it - it depends on the current space weather, where you are wrt your spacecraft, the engineering of your space suit, etc.) are all behind paywalls. Here’s one, if you can get it: https://link.springer.com/chapter/10.1007%2F978-1-4613-1567-4_6 https://link.springer.com/chapter/10.1007%2F978-1-4613-1567-...
