something else that always makes me curious is why did the likes of russia not bother to go to the moon....i mean did they just take the U.S word for it ?nothing to see here fellas...and they abandon their own programs...
so were things different back then did the major players all share notes ?

Look -
We should find all sorts of things to match up with the Apollo story, if it's genuine.
But it's just the opposite. Nothing matches up.
It matches a hoax, holding on to its last few threads
Aluminum shielding actually makes deep-space radiation even worse, so we won't use it for our future spacecraft. But nobody points out that Apollo was aluminum. Why do they ignore it?
Guess....
Some scientists believe that materials such as aluminum, which provide adequate shielding in Earth orbit or for short trips to the Moon, would be inadequate for the trip to Mars.

This is the kind of deliberate misinterpretation I'm talking about, Find anyone who denies the CSM was made of aluminium, Then find someone (ideally someone who actually knows what they are talking about) who can prove, with equations, facts and actual evidence, that aluminium was not suitable for a short term mission to the moon.
Aluminium is not suitable for long term missions. Everyone knows that, particularly those involved in researching an planning long term missions. Like these people at NASA:
science.nasa.gov...

I've only seen papers that firmly state how aluminum is a VERY POOR shield in deep space.

Think of Antarctica where so many countries go to study " a new continent ' it seems a little weird that only America has sent people to the moon for the last forty five years with the major advances in global technology.
Unless of course something happened or rather is continuing to happen...

Why do they ignore it? Well maybe because even the longest Apollo missions spent little more than a week in deep space, whereas future missions might last years!
If by "making it worse" you are talking about Bremsstrahlung, you might want to check your maths. A low Z number means LESS Bremsstrahlung. Aluminium has Z=13, which is lower than any other metal except lithium, beryllium, sodium or magnesium.
Ponder why we are unlikely to make spacecraft out of these metals...

That is yet another problem for Apollo.
We discovered that aluminum is a poor shield against deep space radiation quite recently.
Apollo supposedly flew in deep space nine times, over a few years, yet remained blissfully ignorant ??
That's a good one.

No, I'm talking about fragmentation, where secondary radiation is created from the material itself.
Aluminum is a good example - fragmenting particles of (deep space) radiation inside the craft. I'd like to know what is 'adequate' about that....so please, tell me all about it!!
