Are you seriously using ad hominem? It's 2015 bro. You need a grow a better argument than that. Russian Altitude record is at 475km. All the experts agree on this because it is a basic fact of the historical narrative. There is no interpretation needed to understand the russian record of space altitude exploration. And that russian altitude record is 475km.
The problem with some of the Apollo Cult Believers is that

it isnt a limit.. its merely an altitude that a russian person has yet to pass..

The operative phrase being "as yet." There are plans to send a Soyuz spacecraft on a lunar orbiting flight, exactly the mission it was originally designed for. When that happens, will you admit that the Apollo program was at least possible?

No DJW001, you should know by now that going through the FAB and beyond is not possible till now because there is not enough shielding against the radiance.
You will be killed.
nasa is trying to find out how they can go through the VAB and beyond....they don't know how they can, till now.
Because of this we can conclude that the moonlandings are faked.

The SAMA is part of the VAB, the is regularly traverses through it, this is a fact..
Also go back and read the entire paragraph you wrote of the quote. Cherry picking a sentence and putting it out of context is dishonest at best.
The man is talking about the challenge of shielding sensitive electronics which includes life support electronics properly, new electronics are now so much smaller that an electron from the VAB can and will change some of the states of the electronics memories etc, these challenges of shielding the electronics onboard Orion must be solved before they can successfully send a man THrOUGH the vab with Orion. That is what he is saying you cherry picking a quote and putting it out of context is dishonest.

P.s. And what I've been trying to tell you is that the vab has varying levels of energetic particles, the less energetic areas can be protected against, and a trajectory can be planned within these areas, the higher energetic areas are harder to protect against and planning a trajectory around this is very much possible, if you want to claim that we can't send a man through the vab, you are claiming that the high energy areas is everywhere in the vab and completely unavoidable. Which includes the saa. Which is completely false

I posted the entire passage, and linked the clip it was from, so don't accuse me of being dishonest, which only shows you are the one acting dishonestly here.
The problems he mentions are about shielding electronics,
which need to be solved before sending humans through the VAB. Shielding humans is far more difficult than shielding electronics, and it is not close to being solved.
The fact remains we cannot send humans through the VAB yet.
The problem is that we DON'T YET KNOW where, or when, or how, the VAB become highly charged with radiation. Look at all latest discoveries from the VAB probes, so you'll know what I mean here.
That's quite a claim, indeed...
The claim has no evidence to back it up, that's the whole problem.
In terms of hazard to crewmen in the heavy, well-shielded command module,
even the largest solar-particle event on record (November 12, 1960) would not have
caused any impairment of crewmember functions or ability of the crewmen to complete
their mission safely. It is estimated that within the command module during this event
the crewmen would have received a dose of 60 to 100 rads to their skin and 10 to 30 rads
to their blood-forming organs (bone and spleen) (refs. 4 and 5).

If true, all the problems we have today wouldn't exist, but that's not the case at all.
Do you agree with their claim, noted in that paper, or do you not?
If you do, what do you believe supports their claim?

Main reason why NASA sent the two probes into the VAB - to know how, or even if, we can send humans safely through the VAB, beyond.
The probes serve many other purposes, sure. Unmanned craft will benefit from the studies, and much more. In fact, we've already gained more knowledge of the VAB from the probes than all the decades before it did. Which means, we knew diddly-squat about the VAB environment, back in the Apollo-era....to put it mildly.

yes he is, he was not talking about the challenges of shielding humans, which is what you were trying to establish.
originally posted by: choos
are you sure?? i suppose you have some evidence of this??
did you know one single electron or charged particle can affect electronics?? which can lead to minor damage to complete failure
are you suggesting that a single electron can kill a human??
originally posted by: choos
if thats a problem why dont you see a problem in your inability to back up your claims that GCR's would be deadly in as little as 6 days??
originally posted by: choos
if the claim has no evidence to back it up, how do you think they were able to estimate the dosage received by the astronauts if they dont have any data to back it up?? the very next sentence gives you references:

A "well-shielded command module", now that's a good one!!
Why don't you tell me exactly what materials they used in the command module to make it so "well-shielded"? I can't wait to hear all about it!.....
Oh, right, - iirc, at that time, they also believed that aluminum was an adequate shielding material for a manned spacecraft against any deep space radiation, including GCR's.
They also believed the VAB were slow-moving, waxing and waning, at the time, not the unpredictable, instantly changing environment it ACTUALLY is, that becomes highly energized with radiation in seconds.
But go ahead, please...

protection against solar activity has always been an issue.. Apollo astronauts would have survived, but their mission would have been drastically cut short..
They said it would not impair their safely completing the mission, though. It seems you disagree with NASA's claim that their mission would be completed, and not impaired, under such a scenario...so why do you dispute NASA's claim?
originally posted by: choos
also, you keep trying to say they dont have evidence for this or evidence for that.. have you noticed that ALL of your claims have no evidence?? where as the claims that they make has raw data to back up their claims (apparently you say its not evidence)
you have NO raw data that is capable of backing up your claims, you have mere speculation and conjecture at the very best.
The claim about aluminum intensifying GCR radiation is THEIR OWN CLAIM. I've told you that over and over, but you don't grasp this FACT, so I'm telling you yet again. IT IS THEIR CLAIM, NOT MINE.
They do not have raw data on this, because the only way to get raw data for it would be to put humans into deep space, in an aluminum spacecraft, measure the GCR radiation before the aluminum, outside the craft, and measure the GCR radiation inside the craft, after it has fragmented into smaller particles, which have become more intense, more hazardous to humans, than the original particles were, outside of the craft.
That's the easy part. Next, they have to assess the effects of GCR fragmentation on the crew, upon their return to Earth. Both for short-term effects, and for long-term effects, which means the astronauts must be monitored for the effects over the rest of their lives, perhaps 50 years or so.
They probably wouldn't get any volunteers, if they ever wanted to try it, first of all.
They'd have to vary the missions in duration, from a few days, to a year, or longer, in order to get the entire spectrum of data
and variables measured properly. Then repeat the missions, to confirm their original measurements. If the second set of data is not similar, they' have to run more missions, and see if it still conflicts. If it does, they'd need more missions, until the conflict is resolved. Monitor every astronaut from day one, every week, over a year, then twice a year, or annually, for the next 50 years. After they all have died, they can compile all their data together, to compare and contrast each and every one of the various factors.
No such data exists, as you should now realize, because they can't actually GET this data.
But they have studied what aluminum does when GCR radiation contacts it - the radiation goes through the aluminum, and fragments into many more smaller particles, which are more hazardous to humans than before going through the aluminum.
They DON'T KNOW how much more hazardous it is to humans after the fragmentation, because to measure the effects, to know exactly how much more hazardous it is with aluminum, requires a crew in an aluminum craft, going into deep space, and back to Earth, and then the effects of the GCR radiation can be measured, both in short-term, and in long-term, to get this data.
But no humans have done this, so no data can be obtained.

He said we have to resolve those problems before we can send people through the VAB, which is what I wanted to establish. And what I didestablish.
Shielding humans from deep space radiation, or any other hazard/problem within the deep space environment, is FAR, FAR more difficult to resolve than shielding electronics...without a doubt.
Radiation has both short-term effects, and long-term (lifetime) effects, for humans, Both effects must be fully understood before knowing how to shield humans. Radiation has a short-term effect on electronics, but (by and large) it has NO long-term effects.
Humans have far more value than electronics, there is no comparison between protecting a human life and protecting a non-living computer
If a human dies in space, we cannot replicate him. If an electronic component is fried in space, we CAN replace it with a duplicate component. Obviously, humans are much more precious to shield from harm than computer chips are. (If you are a normal human, that is, not an evil, war-mongering, money-lending banker scumbag!)
Another point - I've shown you they keep revising the shielding requirements for humans in GCR radiation studies, greater and greater shielding is required over and over the years. That shows they do NOT know what is actually needed to shield humans in deep space. It is MUCH more complex to figure out what adequate shielding is for humans in deep space than it is for electronics.
Last point - we have many unmanned craft in deep space, and with electronics on board, which (in general) have been able to function in this environment, for years! We have no humans in deep space, obviously.
How do you not understand any of this?
Because I didn't make such a claim, you made it up.

so even though NASA has given the main purpose of the Van allen probes as:
º Discover which processes -- singly or in combination -- accelerate and
transport the particles in the radiation belt, and under what conditions.
º Understand and quantify the loss of electrons from the radiation belts.
º Determine the balance between the processes that cause electron
acceleration and those that cause losses.
º Understand how the radiation belts change in the context of geomagnetic
storms.
which is studying how solar activity affects the VAB..
however, the real main purpose of the van allen probes is "to know how, or even if, we can send humans safely through the VAB, beyond." all because you say so and everyone must listen to you.
