James A. Van Allen - Dies at 91
Diamonddavej writes "The New York Times reports that the respected astrophysicist, James A. Van Allen, died yesterday at the age of 91. Apparently the fellow regularly worked at his office/laboratory up until a month ago. Prof. Van Allen team designed the Geiger counter that flew aboard Americas first orbiting satellite, Explorer 1. It detected unexpectedly intense levels of radiation caused by energetic particles trapped in the Earth magnetic field, the magnetosphere. The belts of radiation were mapped and characterised by later missions and were named the Van Allen belts in honour of their discoverer."
Does setting off an atomic bomb in the atmosphere of your home planet sound like a bad idea to you? Sounds more like the threat of a Bond villain than an action of the United States government. I'm not sure what the motive was for these tests does anyone who knows Van Allen's research have an answer?
My work here is dung.
Since it is not being reported by Philip Chien, formerly of Wired so, I suppose, we can believe it . . .

Ah, it is the New York Times, which is much more accurate than an Examiner story, compare and contrast at the link

I just heard some sad news on talk radio - respected astrophysicist, James A. Van Allan was found dead in his Maine home this morning. There weren't any more details. I'm sure everyone in the Slashdot community will miss him - even if you didn't enjoy his work, there's no denying his contributions to popular culture. Truly an American icon.
What respect the author must have for Mr. Van Allen... he can't even spell his name right.
... has Netcraft confirmed this?

NASA looses the tapes of the moon landing and Mr. Van Allen passes away. If I remember correctly the Van Allen belts figure prominently in several anti-moon landing conspiracy theories.
Gentlemen, let the speculation begin!

Radiation poisoning?

Weird, I didn't know this but according to Wikipedia, the number of Van Allen belts has tripled in the last three months.
Why do the taglines just keep getting worse?
I draw the line at bad clothing puns.
Somebody sack the writers.

Dr. Van Allen was a staunch advocate of planetary exploration with robotic spacecraft and a critic of big-budget programs for human space flight. Describing himself as "a member of the loyal opposition," he argued that space science could be done better and less expensively when left to remote-controlled vehicles.
Prof. Van Allen team designed the Geiger counter that flew aboard Americas first orbiting satellite, Explorer 1. It detected unexpectedly intense levels of radiation caused by energetic particles trapped in the Earth magnetic field, the magnetosphere.
Unfortunately for astronauts Reed Richards, Susan Richards, Ben Grimm, and Johnny Storm, NASA hadn't thought to send up an unmanned probe first.

Don't retire - You'll die!
not that i have anything to worry about, to have any kind of retirement i'll be working until i'm 91, too.

Anyone else misread this as Van Halen?
Yes, you certainly can.
"Space Age" used to mean "so new it's futuristic". Now it's starting to mean "ancient history".
And all we got is lots more crappy TV.

The Soviets once accused the U.S. of creating the inner belt as a result of nuclear testing in Nevada. The U.S. has, likewise, accused the USSR of creating the outer belt through nuclear testing. It is uncertain how particles from such testing could escape the atmosphere and reach the altitudes of the radiation belts. Likewise, it is unclear why, if this is the case, the belts have not weakened since atmospheric testing was banned by treaty. Thomas Gold has argued that the outer belt is left over from the aurora while Dr Alex Dessler has argued that the belt is a result of volcanic activity. - ha-ha. That is quite weak, US and USSR used to be worthy opponents, don't you think so? :)
You can't handle the truth.
The belt and NASA made him famous, but James was doing some crazy stuff with rockets way back when, including the Rockoons, which were rockets launched from high-altitude balloons to gather information, test flight and fuel capacities, etc.
The Coast Guard let him shoot the Rockoons off the coast towards Greenland. When he first tried them, the rockets refused to fire. So Van Allen took some cans of orange juice, heated them, put them in the gondola next to the rocket, and covered them in insulation.
Presto. The rockets fired.
The definition of a great and honorable scientist; inquisitive, intuitive, unpretentious, and brilliant.
after David Lee Roth left. ;)
This belt's for you.
In today's Cedar Rapids Gazette, the obit was the front page story. Took half the front page, and 2 full pages on the inside. I was really pleased to see such great coverage!

His support was crucial for the passage of the Launch Services Purchase Act of 1990 which, although largely resisted by NASA at the time became a bellweather for future launch service policy.
PS: I do regret not having mentioned Dr. Van Allen's support during my Congressional testimony.
Seastead this.
Only marginally on-topic I know, but speaking of Van Allen:
Information on physiological effects on humans passing through the Van Allen belt seems to be distinctly lacking.
Given that at least 29 people are reported to have passed through it during the Apollo programme, I would have thought there would have been extensive tests done both 'live' during flight and upon arrival back on earth. Does anyone know if such studies were done?
It probably won't shut up any of the moon landing naysayers but would be interesting nonetheless.

... that he would teach freshman astronomy. He wasn't just a great researcher, he was also a great teacher.
I worked on the same floor as Van Allen at the University of Iowa when I was an undergraduate. He was quite an amazing guy - even at 90 years old, he still came to his office nearly every day to work on data from Pioneer. I had a number of conversations with him, and he clearly still loved what he was doing.
My fondest memory of him is when he was presented with an award at Iowa a few years back. The actual award was a glass globe with some intricate internal designs composed of another material. However, the globe was much heavier than it appeared. So he spent the next few minutes explaining to those around him how we could figure out its density using size and mass, and then figure out the internal composition based on that. Then he actually went through the rough calculation and narrowed it down to two or three likely materials. He was well known around the Physics department for his skills as an educator, and I'm glad that I was able to witness a bit of that firsthand.
Up until a few years ago he was still using an ancient punchcard-based programmable calculator for most of his computations. Van obviously new it was out of date, but he had so much experience with it that he could still use it fairly quickly. He showed me the array of cards he had written over the years for doing things like converting RA/Dec to Az/Alt and performing Newton's method. Around this time, a professor of mine started to teach Van how to use modern programs like Mathcad for doing things like this, and he was very excited and receptive to working in a way that was fairly new to him.
I know a lot of people who really admired this man, and he's really going to be missed up on the 7th floor.
Wait... If it's a classic, then it must be when Sammy Agar still played with them, right?
Announcer: Astronomers from Tacoma to Vladivostok have just reported an ionic disturbance in the vicinity of the Van Allen Belt. Scientists are recommending that necessary precautions be taken.

A nice article in the iowa city news paper

Michael Collins' memoir, "Carrying the Fire," included a table of radiation exposure for all the manned Gemini flights. Two readings were given; one for the commander, one for the pilot (who on some missions left the spacecraft to do some work outside). Gemini X, on which Collins was pilot, had the highest radiation levels, as their flight went in the South Atlantic magnetic anomoly, and others did not. Both are alive roughly 40 years later, in their mid-70s: not bad.

CBC radio's Quirks and Quarks program had a story on November 19, 2005 on the subject of human exploration vs. robotic probes. It's available at http://www.cbc.ca/quirks/archives/05-06/nov19.html with links to OGG Vorbis and MP3 files of the show. Van Allen was interviewed among others.
Of particular note, the Bush administration's plan to send astronauts back to the moon, the de-maintaining of Hubble, and the cost of a Mars mission (one manned trip to the moon to look at rocks = 700 mars explorer missions). While the show itself takes a non-editorial stance and finds interviewees on both side of the debate, one can clearly see that Van Allen is no looney, a bright mind even in his 90's.
One can quickly make the analogies that:
- Looking Glass : Galileo
:: Hubble Space Telescope : 21st century scientists
- House arrest : Catholic Church
:: Fund diversion : evangelical Bush administration
- Remote sensing probes & space telescope repair : real science investigating cosmology and origin of universe
:: human Moon and Mars mission : money wasting diversion from real science, hoping to extend the suspension of disbelief in religion a little longer, by preventing more erosion of the religious god-created, human-centric universe by empirical scientific evidence.
(reference: http://news.com.com/Hawkings+cosmological+riff/21Program Summary
The development of new plans for human exploration of the Moon and Mars has raised an old argument again. Should we be sending humans into space? Many scientists have argued that robotic probes, rovers and satellites have produced far more science at a far lower cost than human astronauts. Will this still be the case as we look beyond Earth orbit?
Space pioneer Dr. James Van Allen, the Regent professor of physics at the University of Iowa, has worked with space probes like the Explorer, Pioneer and Mariner missions since the earliest days of the U.S. space program. In his view, human astronauts are obsolete.
Dr. Van Allen made so many more contributions to space science than just his discovery of the radiation belts. He was one of the founding fathers of the field of magnetospheric physics. He was also involved in the first satellite missions to visit Venus and Mars, as well as the Pioneer missions to the outer planets. Much of his opposition to manned space flight was motivated by the success of these early satellite missions and the enormous scientific return from them. He believed that unmanned missions like Pioneer could contribute much more to our scientific knowledge than manned missions. He also argued that unmanned missions were more cost effective than manned missions. For more information, I suggest reading his autobiography.
