No, that is NOT what I claimed!!
I said they were not going to build spacecraft with aluminum as shielding for a manned deep space mission...
Got it, yet?
The final incarnation will be made of Tantalum, Tin, Zirconium, Aluminum, and Polyethylene. The heavy metals will block gamma rays while ions and neutrons are captured by the hydrocarbons of the polyethylene.

Oooh look, Aluminium.
Just as with Apollo, Aluminium is a construction material that happens to provide some radiation protection against some radiation types. Other materials and construction techniques provide other protection.
You are the only person claiming that Apollo was only built out of Aluminium and for the sole purpose of providing radiation protection.

shifting the goal posts much??
Orion uses aluminum in its construction. You are arguing that any aluminum is forbidden because it is "proven" (with false data I should add, again your claim) to be merely unsafe.

What you can try doing is presenting any evidence, any at all, that tells us at what point we get a dead astronaut on the way to the moon.
Or indeed answers to any of the other repeated questions you've avoided.

You assume astronauts flew to the moon, and want me to prove when they'd be dead going there??
Nobody went to the m8on, nobody went into deep space, so nobody would have died. Do you think data is available showing how they could have lived if they went, even though they didn't??
You need to have a valid question before you start demanding I have the burden of answering it.
You are hardly one who should spew on about avoiding questions!!
Do you want to explain why the experts said aluminum mqkes radiation worse in deep space?
Why do the experts say future manned missions into deep space will not use aluminum shielding?
Why do you Apollo-ites believe the experts have excluded short - as in, all Apollo-length - missions from their above statements?
By saying long missions are a greater concern than short missions, that is their focus.
To try and resolve the problems of long
missions would resolve the lesser problems of
a short mission, obviously.
To say long missions are the greater concern, greater problems, compared to a short mission, does not exclude them.
They would mention any sort of exception to their statements. If they do not indicate any specific mission, as included, or excluded, then it applies to ALL of the missions.
As much as you'd like to put words in their mouths, that is not the reality
missions.

So what you are arguing now is that aluminum can be used but is advised not to?
so Apollo is completely possible even if it used only aluminum, ok cool but you didn't need to waste a year arguing to us that Apollo was completely possible

You think that even though Apollo was mostly aluminum, it was not the only thing shielding the radiation in deep space...
Aluminum intensifies deep space radiation. Shields are generally used to block out radiation, so how would you say aluminum helped in shielding Apollo spacecraft?
Well, I guess it didn't really help a whole lot, right?
So when the radiation hit aluminum, it became worse.
But then, the radiation came to a thin layer of fibrous insulation - the true radiation shield of the Apollo spacecraft.
I would like to know all about this fibrous insulation which you claim was a radiation shield.
I'm quite sure you'd like to know al about it, even more!!
Now, the fact Apollo had a thin layer of fibrous insulation does not prove it was an adequate radiation shield.
I don't recall they even said it was their radiation shield, or part of it, though...as it would be mentioned at the time, of course.
No documents on the radiation shield, which I know of...so where are the documents on the radiation
shield?
And the papers I cited say aluminum is no shield for deep space, but never mention this fibrous insulation which makes a great shield.
They would also have no reason to say aluminum would not be a radiation shield for deep space missions, since Apollo didn't use it as a shield, but had fibrous insulation between thin aluminum layers, and that was their shield, in deep space!!
Maybe you should tell the experts about this fibrous insulation which nullifies the crappy aluminum that intensifies the hazard...

If I told you that what you refer to as pure aluminum is classed as, I think, 4000 series aluminum.

I was hoping for this rant of yours, you say Apollo spacecraft was using pure aluminum in its construction??
Can you prove this??
If I told you that what you refer to as pure aluminum is classed as, I think, 4000 series aluminum.
And the aluminium used in the Apollo spacecraft was actually 7075, which is a high grade aluminum alloy.
So in actuality, what you refer to as the "aluminum" used in Apollo missions and the aluminum that you believe is very bad because you think it is pure aluminum is wrong.
But feel free to prove Apollo used pure aluminum

What do they refer to as aluminum, then?
They say aluminum intensifies radiation in deep space, and won't be used to shield humans in any future missions in deep space.
You said it was aluminum, but it had other materials to shield humans in deep space, like fibrous insulation...
Now, you say it was not aluminum, at all, it was an alloy of aluminum...
Where do they claim Apollo was not aluminum, but an alloy which is part aluminum, with other materials?
Command Module
The CM was a conical pressure vessel with a maximum diameter of 3.9 m at its base and a height of 3.65 m. It was made of an aluminum honeycomb sandwhich bonded between sheet aluminum alloy.

You make claims that never have supporting evidence, and this is just one more example...
As usual..
