I dropped my IEEE membership more than a decade ago, for several reasons. Infestation of stupid, arrogant leftists was one of them.
This Jan fellow, however, who posted the article, has his own agenda. He's pushing the "Moon Landing was a Hoax" lie, using the Van Allen radiation BELTS (they're called "belts" for a very good reason) to claim that a manned mission to the Moon is impossible. He does this despite having been told, repeatedly, how the Apollo missions navigated around the most intense parts and passed through the fringes very quickly.
I suspect that he, and perhaps a couple others, are trying to distract from the ongoing Biden Crime Family scandals.
Just curious, certainly not meaning to encourage the moon-landing-was-a-hoax crows: Why do we never hear about Van Allen belts when they describe launch timing? LIke, we hear, delay...delay...delay... oh, we have to scrub it because the weather. Never delay... delay... oops, now there’s a Van Allen belt? TBF, they DO always talk about “launch windows” without describing why they are when they are.
