I mean manned missions into deep space out past the Van Allen belts etc.
Not manned missions that orbit the earth or unmanned deep space probes.
My uncle worked his whole life in aerospace (communication satellites). He had secret clearance security status. He once described how satellites sometimes "fly too high" (away from Earth) and "Zzzck!" They short circuit because of the Van Allen belts. So I asked him "if today's satellite electronics are so fragile
with the kind of shielding they have to protect them, but the Van Allen belts routinely fry them anyway, how did the Apollo lunar vehicles not get fried when NASA admitted that it didn't shield the vehicles? He was stumped.
