TRUE OF FALSE

1. The Van Allen Belt protects the Earth from being bombarded by solar radiation. TRUE OR FALSE ?

2. We living on this side of the Van Allen Belt experience much less Solar Radiation than, say, astronauts trying to fly to the Moon. TRUE OR FALSE ?

3. The Astronauts who flew to the Film Studio in 1969 (oops, the Moon !) had special protection to prevent them being fried alive by solar radiation during their voyage to Moon and back. TRUE OR FALSE ?

Thank You

The Van Allen Belt protects the Earth from being bombarded by solar radiation.

Neither true nor false; the Van Allen belt protects against charged particle radiation but does not protect against electromagnetic radiation. The atmosphere attenuates most electromagnetic radiation in the ionizing bands. This means that on Earth one is protected from both charged particles and electromagnetic radiation. In low Earth orbit one is protected against particles, but not from such things as hard x-rays. Outside the Van Allen belt one is subject to both particle and EM effects.

We living on this side of the Van Allen Belt experience much less Solar Radiation than, say, astronauts trying to fly to the Moon.

True in general, over time.

The Astronauts who flew to the Film Studio in 1969 (oops, the Moon !) had special protection to prevent them being fried alive by solar radiation during their voyage to Moon and back.

True. The Apollo spacecraft incorporated shielding intended to attenuate the effects of radiation that the crew was expected to be subjected to.

False dilemma. Radiaition, space travel and shielding are complex phenomena that cannot be oversimplified to the degree you have done so.

True in terms of particle radiaiton, false in terms of EM radiation. The van Allen belt as I understand it refers to the belts of charged particles around the Earth. Strictly speaking these belts are not actuall the thing protecting Earth, but are merely regions of high concentrations of particle radiation. It is the Earth's magentic field that does the protecting. forming the belts in the process.

True in broad terms.

True, though I suspect from your tone that your idea of 'special protection' and what that actually entails are very different. The type of radiation in the van Allen belts is particle radiation: easily (and best) shielded by light metals and plastics such as those used in the construction of the spacecraft. If you expect the 'special protection' to take the form of a big lead screen with a label on the blueprint saying 'radiation shield' your expectations are sadly way off the mark.

. . . which is why I'd answer that question as "false."

The Earth's magnetic field deflects many (not all) charged particles, but I'm not aware that the Van Allen belts are in themselves protective.

It may also be worth mentioning that the flux of particle radiation outside the VABs is typically not particularly high (except in the case of a solar mass ejection that takes an unfortunate course). The only consistently high flux is found within the belts themselves. This exposure can be minimized by lightweight shielding and by choosing a trajectory that minimizes the time spent in the high-flux areas.

At NASA anything's possible ! Even ignoring solar radiation.

I'm not at NASA, but I'm certainly not aware of them ignoring solar radiation. Quite the contrary, in fact.

Do you have some evidence that they are?

As a "test" of how NASA "ignored" radiation I did a quick google.

Top of the list was this: http://lsda.jsc.nasa.gov/books/apollo/S2ch3.htm

Interestingly, it turns out even man-made radiation sources from inside the Apollo craft were considered...

I thought this was very interesting. (Again, my personal "main" anti-hoax proof comes from this kind of thing. The absolutely mind-bogglingly incredible detail available on how it all was done.)

So the reply is, no - NASA didn't ignore solar radiation, in fact they did a much much more detailed study (into all radiation sources) than I suspect the hoax believers could possibly imagine.

The only "ignoring" here is done by you, relating to the answers to your questions, and - in a broader sense - the facts.

I beg your pardon, but you should really tackle one conspiracy at a time. There are questions still open on the Chemtrail thread. You are acting like a troll, and wasting everybody´s time [including yours].

Actually it is the conspiracists who ignore solar radiation, which is to say they ignore its true nature and insist on simplistic, unfounded formulations of it.

Solar weather is a factor that must be dealt with among all spacefaring nations. Many commercial spacecraft operate in and beyond the Van Allen belts. NASA's operations account for a very small fraction of what happens in space. Literally tens of billions of dollars of worldwide commerce is involved in private spacefaring, and you simply can't credibly say that NASA must be hiding the true nature of solar radiation from the world.

Those are the facts that conspiracy theorists ignore.

I watch TV via the Sky Satellite. I am sure if you live in the UK you must know people who have Sky TV. The Astra Satellites are Geostationary, they are subject to all the radiation that the Apollo missions were subject to. As a lot of the Data that was used to build the Astra Satellites was obtained from NASA I would say it was accurate otherwise they would have been fried by now.

How do you account for this?

I'd like to know how you can classify sending up about twenty or thirty probes over a decade with specific radiation measuring devices as 'ignoring' it.

Radiation in space was known about for many years before Apollo, and NOT just by NASA. It has been studied continuously ever since, and these days billions of dollars of private commercial revenue depend on accurate information about solar radiation. And yet, despite this, not one person whose job actually entails studying the radiation and designing things to survive it has said 'hang on, there's no way men could survive this in what NASA says the Apollo missions used'. You might also consider the lack of thick radiation shielding on the Soviet Soyuz spacecraft, designed forst and foremost as their manned lunar vehicle.

that's because NASA pays everyone with wheat.. oh, wait, that's something totally different. i get my conspiracies mixed up sometimes.

beethoven, did you abandon the chemtrails thread for lack of evidence? I was looking forward to a discussion.
Your agressive, but unsubstantiated, posture here is familiar. This forum is pretty strict when it comes to claims, and innuendos.

What facts do you have about solar radiation and the belts that might be interesting here?

Dave,

Let me make it very simple. Manned space flight outside of the Van Allen Belt is science fiction. It was, and is nothing but science fiction. Let's stop telling lies. The radiation that would exist beyond the Van Allen belt would kill any astronauts flying even to the Moon. It would grill them. Time to stop the fantasy. Man has NOT walked on the Moon. He has never gone beyond the Van Allen Belt. Nor can he do so. Isn't it time to admit that the 'Cold War' Apollo missions were just a hoax. Then the human race can start to get back to reality rather the P.R. side of the industrial/military complex that is NASA manned space flights.

The Van Allen Belt exists to protect mankind from being fried alive. And in 1969 NO provision was made in the Apollo flights for this factor. Tell the truth and let's stop believing fairy stories.

I'll make it even "simplier"...

Do you have evidence to present, or will this be "more of the same" from yesterday?

Yes, I have lots of evidence. But let's get back to basics. You claim that man has walked on the Moon. He did so (you say) from 1969 onwards in a series of manned space missions to the Moon. What evidence do you have that the Apollo crews had any special protection against radiation beyond the Van Allen Belt so that they could survive space flight to the moon, and could survive going there and coming back ?

Was their protection -

a. 20 feet thick lead sheeting ?

b. A sheet of foil paper ?

c. None of these ?

Produce your evidence these Apollo flights were equipped to overcome the solar radiation in outer space.

Still waiting, 40 years later !

I'll make it as simple as possible. Beethoven likely did all his research on Youtube and consequently knows everything he needs to know to support his belief. Since he is already in possession of all the facts he requires, then he is either here to teach or to troll. Since he is also unarguably and demonstrably wrong, I therefore suspect he recently occupied the underside of a bridge.

Great, let's have the evidence that the Apollo spacecraft incorporated shielding intended to attenuate the effects of radiation that the crew was expected to be subjected to.

And what ''shielding'' was this ? Time to produce some details.

Any details yet ?

Then present it...

Not impressed with this continued "shifting" of the burden of proof...

The fact that the evidence is conclusive that 12 men did walk on the moon makes everything else moot. Clearly they were adequately protected.

Well, the burden of proof on those who claim that man has walked on the moon. Now, please provide us with details of what shielding (if any) was on the Apollo craft. And what shielding provisions were made in 1969 for the moon landings.

Should be simple for you to provide, right ?

Except that the manned moon landings are nothing but a fairy story invented by NASA and the industrial/military complex.

40 years later science is still waiting for this basic information.

No it isn't.

You claimed [in some of your threads] to be an academic in the field of History. If your behaviour and mindset in this thread and others [like ignoring direct questions, prejudiced ideas] are examples of the academic attitude, I fear for the future of the Academia.

No. The burden of proof is on those who claim it was all faked. The fact man has walked on the moon has been established; the other way around hasn't.
Sounds like you're assuming that this basic information doesn't exist. You are wrong.

Your statement presupposes intent. Is Earth's Van Allen radiation belt aware of mankind's existence? Does Jupiter's Van Allen radiation belt exist to protect Jovians, sentient or otherwise?

Your statement should have read, "The Van Allen Belt protects mankind from being fried alive." Better would be, "The magnetosphere protects life on Earth, but the Van Allen belt is a threat to living things and machines that dare to cross it."
