Does this evidence prove the hoax?
Of course not, which is to say "prove the hoax" would entail actually discovering a hoax, not merely inferring or supposing a hoax because some other evidence didn't add up. That part of the argument is basic logic and reasoning. Lack of evidence for one thing does not automatically prove some other affirmative claim.
Missing lunar rocks
Like any valuable curated item, lunar samples attract loss and theft as well as fraudulent claims of ownership or sale. Most of the samples in question are quite small. The total mass of retrieved lunar samples is around 400 kg. I'm not sure how stories of loss, theft, recovery, or third-party fraud constitute proof in any way that the missions were hoaxed. Could you flesh out that line of reasoning?
Missing telemetry data
This argument presumes that NASA should have curated the tapes in the certain way the conspiracy theorists impose. That imposition is based on erroneous notions such as the telemetry tapes being the "original" records of the mission, especially of the television coverage. The process of converting the embedded television signal to a standard signal, such that it could be playable by ordinary video equipment, was accomplished "on the fly" during the mission by highly specialized, custom-built equipment. The telemetry tapes were retained temporarily only against the possibility that such an on-the-fly conversion would have failed. Reading the tapes themselves requires large, finicky equipment, only one example of which has survived. While the telemetry tapes are the original recordings, they are not the primary source of data, nor an especially useful source. Only in very recent years have new techniques arisen to glean more from them than the original plan called for.
They are also very large. Each tape is the size of a trash-can lid and records only 15 minutes worth of telemetry. They are very expensive and very bulky to store. And in the early 1970s they were also quite rare. Memorex, the company that supplied the original tapes, used whale oil in the binder. With the advent of the Endangered Species Act, they were called upon to find a more environmentally responsible method. They were not able to do it in time, and NASA was forced to re-use Apollo tapes for ongoing missions. They did not explicitly use the Apollo 11 tapes, but the tapes were not labeled in a way that made it easy for technicians to identify them in time.
In short, the claim that NASA somehow intentionally destroyed the original records of Apollo 11 is ludicrous. The telemetry tapes themselves were useful only so that data could be extracted from them later, which was done. The data they contained is safe. The telemetry recordings themselves are a red herring.
What does this means?
It means if you spent a year in space outside the Van Allen belts, you could be expected to absorb a certain amount of normal space radiation, in addition to possibly enduring one of half a dozen or so major solar events that occur. However, for a short two-week mission the normal level of radiation is suitably attenuated by the spacecraft, which provides around 7 g cm
-2 of shielding. No major solar events occurred during any of the Apollo missions. The information on that page is true, but it is not applicable to Apollo.
Is from some guy named Jay Weidner, is he trustworthy?
No.
Is it possible that USA could have bribed Russia with grain shipments to keep the conspiracy?
Only if you accept the most tenuous of
quid pro quo claims, and believe that international blackmail lasts forever.
