What's it got to do with cosmology?

Galactic Cosmic Radiation (GCR)

Galactic cosmic radiation originates outside the solar system. It consists of ionized atoms ranging from a single proton up to an uranium nucleus. The flux (rate of flow) levels of these particles is very low. However, since they travel very close to the speed of light, and because some of them are composed of very heavy elements such as iron, they produce intense ionization as they pass through matter.

For the most part, the Earth's magnetic field provides shielding for spacecraft from galactic cosmic radiation. However, cosmic rays have free access over the polar regions where the magnetic field lines are open to interplanetary space.

 

Not really anything to do with cosmology though (look it up) and what does that prove exactly?

I'll ask this again Parky? Was the Soviet Union in on the moon landings fake? It's just I can't see them (after they tracked the goings on so closely, etc.) going along with it. What with it being just about the height of the Cold War.

 

I refer the honourable gentleman to the answer I gave last year.

 

 

This is summat people are mystifyied about:

 

 

 

"They should have been fried"

Then of course there is always the question of exactly how did the Apollo ships make it to the moon? Outer space is a minefield of deadly radiation emanating from solar flares emitted by the sun. Your average astronaut (like those responsible for fixing the Hubble telescope) orbits the earth in near space and are protected by the Earth's Van Allen belt. The moon though, is 240,000 miles distant and lies way outside this safe band. Astronomical data shows that during the Apollo flights 1,485 such flares occurred. It is the belief of John Mauldin, a physicist who works for NASA, that in order to be protected from the radiation, shielding at least 2 metres thick would be required. Yet the walls of the Lunar Landers which took astronauts from the spaceship to the moon surfaces were according to NASA "about the thickness of heavy duty aluminium foil." Now, even giving NASA the benefit of the doubt (well it is almost Christmas and I'm in a generous mood), if the astronauts were protected by their space suits, why as Rene asks, weren't such miracle suits used by rescue workers as protective gear at the Chernobyl meltdown which released only a fraction of the dose the astronauts would have encountered?! Not one Apollo astronaut ever contracted cancer - not even the Apollo 16 crew who were on their way to the moon when a big flare started. As Rene rather eloquently puts it: "they should have been fried.""

 

That article doesn't even get the basics right, the Van Allen belts were supposedly the cause of fatal radiation to astronauts, not protective of it. Bearing this in mind, how can you take it seriously?

 

Of course, the fact that every reputable biophysicist in the world disputes that short exposure to this radiation is dangerous, including Van Allen himself before his death, seems to slip the minds of the Parky loons.

 

Yes but it blocks dangerous solar radiation from the sun.

Never heard that before. Source?

 

Just tap it into wiki ffs!!

So I have to research your patter now do I? No thanks.

 

I'm shocked at your lack of cosmology....Where are my tuition fees??

 

If you can't do, teach.

YOU said the basics were wrong earlier without any backup...Just showing you that the Van Allen Belt although lethal also protects earth in other ways with its field. YOU clearly weren't aware of this....Why not just admit your ignorance?

 

Listen man a lot of the ideas about the conspiracy about he moon landings have been shot down and for good reason and I myself are in agreement with them. But for me the radiation issue is the last one that has yet to be clearly explained by NASA. Just summat I'm interested in....Don't give a monkeys if they landed on the moon or not really.

Would you concede that most conspiracists have blamed the Van Allen belts themselves as being a death sentence for lunar bound astronauts?

 

As for cosmic radiation, as the article states, it occurs at a very low intensity. What type of damage does a single atom of iron travelling close to the speed of light do to a spacecraft or a human body? The answer appears to be not much. Unlike, for instance, being in the proximity of Chernobyl after it had exploded.

 

Of all conspiracy theories, the moon landings one must be the most absurd.

parky hasn't answered my question as to why 99% of conspiracy theories are 'Merican based

 

could it be that they are a nation of undereducated, unread, credulous loons???????
