If you believe that rockets can operate in a vacuum then this article talks about measurements taken of the radiation levels in the belts.
(Bolding mine). I assume, from the way that you have phrased this, that you have another crank-magnetism belief that rockets can't operate in a vacuum? If that's the case, then how can you use an article that used information gained by flying a rocket through the VA belts as evidence???
So go on, enlighten us.
I'm just using someone (Van Allen) that NASA fan boys find credible. I don't believe we really know what is beyond the "dome" of earth. I also think Van Allen is bought and paid for by NASA. I just find it humorous that the fanbase picks and chooses what it wants to hear because it validates their globe earth religion.
Again, you have a person, Van Allen, would be respected by NASA saying there is too much radiation in the belts and then you have NASA stating they don't know how to get through them to get to Mars yet, even though its been supposedly done 7 times. LOL.
And then the nasa apologists will "but......but...but...." to soothe their own conscience.
