A Look Back At Bombing the Van Allen Belts
An anonymous reader points out a recent story at NPR describing one of the greatest lightshows in history — a US hydrogen bomb test 250 miles above the Pacific Ocean in 1962. The mission came about after James Van Allen confirmed the existence of radiation belts around the earth that now bear his name. As it turns out, the same day Van Allen announced his findings at a press conference, he "agreed with the military to get involved with a project to set off atomic bombs in the magnetosphere to see if they could disrupt it." According to NPR, "The plan was to send rockets hundreds of miles up, higher than the Earth's atmosphere, and then detonate nuclear weapons to see: a) If a bomb's radiation would make it harder to see what was up there (like incoming Russian missiles!); b) If an explosion would do any damage to objects nearby; c) If the Van Allen belts would move a blast down the bands to an earthly target (Moscow! for example); and — most peculiar — d) if a man-made explosion might 'alter' the natural shape of the belts." The article is accompanied by a podcast and a video with recently declassified views of the test. They also explain how the different colors of light in the sky were produced.
But if anything ever needed the "whatcouldpossiblygowrong" tag, this was it.
Wow, cool! Let's nuke it and see what happens!
The mind boggles.
Learning HOW to think is more important than learning WHAT to think.
At least it will be a very pretty ending when the nuclear war begins.
These images look very similar to what I had seen last night. The colors bouncing off of the clouds lit up the sky quite well. In fact, if no one replies in the next few minutes I can probably assume that was the end of humanity.
In the end I suppose it's time to do what I always wanted to do. You know, the things we won't do because of societies "rules." However, now that society no longer exists I can finally bathe myself in chocolate sauce, whip cream, nuts and ride my bike around town screaming who has a banana!
Even being the end of the world it's shaping up to be a great day.

It is amazing how the US comes down on on other countries for even thinking of having 1 bomb. While their history is of irresponsibly setting them off like fire crackers on the 4th. How many atolls no longer exist? How many places on earth are radioactive? Yet we are all supposed to believe that they are the sole responsible country on the earth.
The article listed the questions the experiment was to answer and then concentrated on political, visual and show-business value of the experiment but it didn't answer the questions in the end.
Could someone...?

Isaac Azimov wrote a short sci-fi story about an explorer, who had just come back from visiting the newly contacted planet "Earth", adding humans to the "Register Of Intelligent Life". Some minutes later, after the explorer explained how humans tested atomic bombs "on their own planet" the registrar erased the entry as being unqualified for inclusion under "Intelligent".
In case anyone got interested, the 1958 test was called Operation Argus.
By the way, despite what TFA says, there are two electron radiation belts, not just two of them at all; there's also a proton one. Wikipedia considers it to be a part of the inner radiation belt, but the accepted terminology says otherwise to the best of my knowledge.
Hey, Dude look up there! Like, oh WOW, dude!
was to nuke rainbows. A high ranking general was quoted as saying the military applications of rainbows and rainbow based technologies can't be ignored.
Dude! Look over there, oh WOW!

"The Van Allen Belt Is On Fire!"
I like microcars
... but the more I read about what some of these scientists got up to the more I begin to wonder if some of them weren't borderline insane or at least so totally absorbed in the narrow science they were persuing that they didn't think about or didn't care about the potential consequences if things went wrong.
... if this plan involved any of the same people who wanted to set off a nuclear bomb on the moon.
Dear Slashdot: next time you want to mess with the site, add a rich-text editor for comments.
Wasn't this premise the Pilot Episode?
"It's an imperfect world,screws fall out..."
This test series (specifically, Starfish Prime) uncovered the electromagnetic pulse (EMP) effect, an unexpected side effect of nuclear explosions at altitude. The gamma rays from a high altitude burst hit atoms and thus eject electrons high in the atmosphere over a wide area, more or less simultaneously, and the current from the ejected electrons can cause a very wide-spread electromagnetic pulse, which can knock out power lines and electronics at great distances (> 1000 km).
So, I guess we can call Allen the father of the EMP, although I am not sure he would have wanted the honor.
...We got all the result on nuke we ever needed to be echnologically in advance on all other nation of earth. Now let us stop the other getting such tech and we might keep this advance for a long time.
The radiation created in the upper belts
almost stopped the manned space program.
Monitoring rockets were sent up over several months
to test the radiation. And scientists were greatly
relieved that they showed a gradual decrease over only
a few months.
Now you know where the hole is the ozone layer comes from.
What about the depleation of the ozone layer? Any correlation?
Do we know of any long term consequences of these ill-advised tests?
I hate being bipolar; it's awesome!
It's a wonder we're still here. Let's hear it for all the great nerds of our time....

What they don't tell us is that this CREATED the Van Alan radiation belt, not the other way around!
(It's not really surprising that someone who can't spell hypocrisy doesn't really understand it, though. So maybe you deserve a free pass.)
There's a point where hypocrisy is so brazen and open, that it isn't really hypocrisy. US policy is not telling non-nuclear countries, "Do as I say, not as I do." It's merely "Do as I say." You can draw some conclusions from that, and you may very well still end up with some criticisms of US' nuclear policy. But if you call it hypocrisy, then you don't get it.
Those radiation belts are composed of trapped electron and proton particles, bouncing back and forth along those magnetic field lines. There are several numerical models that predict what the population of these particles based on their location, and general behavior under different conditions (solar cycle variations, solar flares, etc).
Anyone building a satellite will use those models to determine what levels of radiation levels the satellite will encounter along its orbit, and add on the appropriate level of shielding to protect the electronics.
A nuclear bomb will never be able to alter the shape of the belts. All it will do is add a spectacular amount of electron and proton particles to the radiation belt, potentially frying the electronics of most of the low to medium orbit satellite (geosynchronous ones will probably be ok). Depending on the size of the bomb, the radiation belt may take weeks or even months to return to a 'natural' state.
There are some experiments in the works to 'tweak' the radiation belts by beaming low frequency EM waves, to change the energy of the existing particle populations. In theory, that will enable some of the particles to become 'untrapped', thereby reducing the overall population.
What an idiot you are. There's no treaty. Fear of nuclear retaliation is the reason you don't attack a nuclear power.
You got it right in the last sentence, but WTF is has to do with treaties, is something in your imagination.
We've found the cause of Global Warming!
When Fascism comes to America, it will call itself Anti-Fascism, and tell you to give up your guns.
It is sometimes baffling that after the past half century of America being a nuclear power, we are actually still here.
has been addressed above. The simple: no mistranslation or opaque intent, only useful idiots like yourself.

Interesting, I thought the whole point was an attempt to disrupt communications so the US could selectively create blackouts.
My favorite part of the NPR article was the sub-headline: "Discover It, Then Blow It Up".
Kinda sums it all, doesn't it?
Don't underestimate the power of The Source
was black comedy.
Turns out it was factual reportage!
but it was _us_ who scorched the sky...

... and you will see that in general terms the above poster is correct. There's no point comparing with utter basket cases and saying we are obviously better because that is answering a different question.
The most insightful point there is the "thinktank" parking lots for poorly educated hard drinking future hangers on to make up numbers in government ARE prone to such incredibly fucked up ideas. They are being listened to for advice instead of real experts with experience and/or education.
We've had the truly bizzare situations of making threats to bomb an allied nation "back into the stone age" and the stupid name calling and attempted framing (for trading yellowcake from Niger to Iraq) of France - vicous and stupid behaviour that nobody would have imagined Reagan, Carter, Clinton, Bush Snr etc to have indulged in.
Aargh, I hate this bit of historical revisionism. Like any city they certainly had civilians in them, but Hiroshima and Nagasaki were both ports, and both had war industries and/or military facilities. They were entirely legitimate military targets by WWII standards and Japan would not have surrendered if they hadn't been atom bombed. (In fact, even after the second bomb there was a failed coup, an attempt to prevent Japan from surrendering.) They only surrendered because we claimed to have more bombs, even though more would not have been ready for months.
It has been convincingly argued that without the atom bombs, Japan would not have surrendered, and that the bombs actually saved lives because any invasion would have been incredibly bloody. (The US is still using Purple Heart medals made in anticipation of the invasion, and near the end the Japanese were arming women and children with bamboo spears to fight the invaders.)

Seeing as how Van Allen taught at the U of I, I found this amusingly ironic! (Iowa City is a nuclear weapons free zone by order of the city council...sometime in the 70s I think)
How many of those secret tests affected our lives? Can you safely say the nuclear residue from these tests did not damage our world? Radiation is energy that affects all matter, we humans are no exceptions. We have the power to destroy us, and the future. I hope we do, mankind doesn't deserve the privilege to live.
Extreme worst-case "Belt Charging" was what is used to define radiation tolerance for military spacecraft. What even more wild than the outlandishly high dose levels and rates of ultra belt charging scenarios is that most of electronics designed for this application actually survive it just fine!
BTW most EMP fears are largely BS and highly exaggerated. It's trivial to harden electronics to survive EMP just fine. Most car are already hardened appropriately for other operational reasons. Most people spewing otherwise have never worked in that field.
We test in the High altitude, deep sea, deep underground- irradiating material for years to follow in the groundwater, trade-winds, and currents of the worlds oceans. Consider the mentalities- Tesla reveals ubiquitous energy which only requires small charges pulsed to the ionosphere which would power the entire planet indefinitely and the only reason I have surfaced for its being left undone is uncertainty of the result of charging the upper atmosphere. But all kinds of misguided testing with toxic fallout is acceptable.
That's a long first name there.
Okay...
Maybe that was his middle name?
In which case, his full name would be the impressively silly James Van Allen Allen Van Allen.
I kinda like it.
