Using NASA’s Van Allen Probes, new research reveals that the Van Allen radiation belts contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.
The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They can wax and wane in response to incoming energy from the sun, sometimes swelling up enough to expose satellites in low-Earth orbit to damaging radiation. The discovery of the drain that acts as a barrier within the belts was made using NASA’s Van Allen Probes, launched in August 2012 to study the region. A paper on these results appeared in the November 27, 2014, issue of Nature magazine.
“This barrier for the ultra-fast electrons is a remarkable feature of the belts,” said Dan Baker, a space scientist at the University of Colorado in Boulder and first author of the paper. “We’re able to study it for the first time, because we never had such accurate measurements of these high-energy electrons before.”
Understanding what gives the radiation belts their shape and what can affect the way they swell or shrink helps scientists predict the onset of those changes. Such predictions can help scientists protect satellites in the area from the radiation.
The Van Allen belts were the first discovery of the space age, measured with the launch of a US satellite, Explorer 1, in 1958. In the decades since, scientists have learned that the size of the two belts can change – or merge, or even separate into three belts occasionally. But generally the inner belt stretches from 400 to 6,000 miles above Earth’s surface and the outer belt stretches from 8,400 to 36,000 miles above Earth’s surface…

NASA’s need to get more Data on the Van Allen Belts before a manned mission can be accomplished
Good thing for NASA the Van Allen belts waned from 1969 thru 1972.
This looks like a push to start the claims that we never went to the moon.
It’s not impenetrable. We did it a bunch of times.
Too bad climate change is destroying the Van Allen Belt. /s Who wants a research grant to study the effects of anthropogenic climate change on the Van Allen Belt?
I’m just here for the Whoopi pics.
I am not able to work out if the “Moon landing was a hoax” people really believe their nonsense or if they are just pretending to believe it.
We should nuke the belts.
Foolish assertion to claim we cannot go beyond it.
In fact, it is no hindrance but rather a great help to us!
The sourced website does seem to post an abundance of foolishness, e.g., “Muscadine Wine: A Promising New Ally in the Fight Against Skin Aging.”
LMAO!

Yes, but I still need suspenders...
Amongst the few I personally know that will argue for the hoaxed moon trips, it seems as though 1 in 6 do it just to mess with people. About half are true believers. And the rest are ‘skeptics’ - don’t see how we got to the moon (cue eyeroll from me), but figure there would have been deathbed confessions or other REAL evidence for the fakery to come out.
It sounds like it’s possible at slow speeds but impossible at faster speeds?
So interstellar space travel might be impossible?
>We should nuke the belts.<
But they might catch on fire and the Seaview is in drydock.

That was posted here, and its wine with the alcohol removed.
What’s the point?…
Yes, I know. We've been there.
