  Thanks, I can hardly get my head around the fact that Apollo 11 received just 0.38 rads passing through an inner belt that can easily reach 100 MeV. For whatever this paper is worth [0], unpredictable solar activity is a major driver on coming out dead or alive as an astronaut. So manned missions are left mostly to luck?? Any details on the optimal path followed by Apollo/Falcon spaceflights or scenario analysis on solar activity impact on manned missions would be greatly appreciated [0] Radiation Analysis for Moon and Mars Missions - https://arxiv.org/pdf/1805.01643.pdf https://arxiv.org/pdf/1805.01643.pdf

    This is how Apollo did it: https://www.youtube.com/watch?v=lNiscigIgBc https://www.youtube.com/watch?v=lNiscigIgBc They followed a flight path closer to the North Pole, which substantially decreased the radiation's intensity and the duration of the astronaut's exposure.
