Feb 11, 2018 at 15:36 comment added Dan Sorensen The Van Allen Belt diagrams really help. I was trying to research whether or not the bets touch at the poles as they appear in these images, but could not find a specific answer.
Feb 11, 2018 at 14:26 comment added uhoh @PatrickWalton these change a lot over time. There isn't a fixed map. It's a pretty complex subject. My goal with these images was to give a better idea about "... there are two (or maybe even three!), and they are fuzzy, and they are moving all the time." They aren't really visible until spacecraft pass through them, so all of these are really just artistic drawing. I'm not an an expert, this sounds like a good, and new question though, either for here, or for Space Exploration SE.
Feb 11, 2018 at 14:13 comment added Patrick Walton Are the gaps between inner and outer belts unprotected from radiation? Do you have an expanded range of distances? It looks like it's zero at the poles and maybe thousands of miles to the outermost belt at the equator.
