Those two had such a great sense of humor and weren't afraid to show their joy at what they accomplished. My greatest regret from that mission was when they tried to remove the video camera that would provide a live feed from the surface, it accidentally got pointed directly at the sun, resulting in the light sensors being burned out. It would have been a joy listening to them as they did their work around the LEM.
Yeah those saticon tubes were so delicate. That particular cam also had a rotating RGB filter that was supposed to result in 'true' color video. The hope was the color wheel was stuck, blocking the camera. That's why Alan Bean tried fixing it by tappy-tap-tapping the camera case with his hammer. It didn't work. Astronaut Bean's camera issues didn't end there. He left one of the Hasselblad film magazines on the Surveyor lander because of a distraction. And either just before, or during splashdown, a 16mm event camera broke loose from its mount and hit him in the face! I always wondered if these were part of his motivation to take up painting. He produced some beautiful works.
Wow! That was absolutely awesome. Thank you SO much for this great work. Those were the days, man. I remember setting my alarm as little kid so I could get up at 5am to watch Apollo coverage.

Bean wasn't that intelligent. He didn't even know where the Van Allen belts were located and stated so on video. To be fair though, he didn't need to know because nobody passed through them, ever.

This warms the gas and then it goes back and flows through a heating coil located inside the supply tank. This dumps additional heat into the supercritical liquid helium inside the supply tank, which boils more liquid to produce even more gas. From there the pressurized helium gas goes to the fuel and oxydizer tanks to pressurize them to greater than about 110 psi to maintain the flow of propellants into the engine.

I would be very interested to learn more and if you can point me to a source, I would be most grateful. You seem to say that there were multiple supercritical tanks.

Fascinating. I knew that Apollo 12 landed at the Surveyor 3 landing site, but never knew how that was achieved. I've long thought that Apollo 11 should have landed at the Apollo 12 site, or one of the other promising Surveyor sites, given how close-run the actual 11 landing was due to unexpected debris fields.
There was nothing wrong with the intended Apollo 11 site. They just didn't land where intended. The landing ellipse for that mission was chosen to be a relatively smooth area. Apollo 11's issue came from navigation errors that took it six kilometres downrange of the centre of the ellipse and nearly into unplanned territory.
Amazing technology for the time. Shame the US was unable to continue with Moon after Apollo, they had the brilliant brains to have made it to Mars many decades ago
The vertical assembly building could hold 4 Saturn V rockets, the plans were for 100+ launches. 1986 was considered the best launch window for a crewed Mars mission. Congress threw it all away, leaving only Skylab, and the flying brick aka shuttle which (technically) couldn’t really even reach earth orbit.
One thing, money (the Apollo program was a huge sinkhole that could not really last for ever); the other thing is that Mars really was considered, which led to the realisation that it would be practically impossible to put a live human there.
We were watching the news on the BBC, from our home in West Belfast and Patrick Moore came on to the tv, just before the weather came on. All excited he told the audience to rush out side and look to the West! And there was stage 2 of Apollo bright in the late autumn sky. It was 6:30pm.
I used to play a game called Moon Tycoon. Some of the audio from this conversation is used as ambient dialogue. Very interesting to hear familiar phrases dotted throughout
What a navigator to fly with. He was clear, precise, confident, gave confidence and optimistic with a positive result. Man these were the days! I wish we had things like this nowadays.
I don't see how you could watch this and listen to Pet Conrad and Al and Bean land in the Sea of Storms and belive the Moon Landing was fake. It's the real thing ! . Thank you for the video.
The faker people are completely devoid of any scientific or engineering knowledge and they didn’t live through it like some us did. They’re basically disaffected losers who think everything is a deep state conspiracy. Most of them barely have high school and certainly nine have any STEM qualifications. Therefore their opinion really is worthless. It’s like debating Shakespeare with someone who doesn’t even know the alphabet. It’s not even worth the effort.
@@philfyphil not a single prominent astronomer, physicist or other scientist or engineer has ever cast any doubt on the moon landings. The conspiracy theorists are all without exception science and tech have nots yammering on about flat earths and firmaments etc, ironically sending out their idiotic nonsense on cell phones to the internet via satellite etc.
To the conspiracy theorists: where is your proof that we did not land on the moon? There is way more evidence that we, in fact, did land on the moon. Friggin mindless trolls.
They have no life. There's no reasoning with those who do not want to listen, change or learn anything new. It's probably best to enjoy space content in a vacuum for that reason; no more comment sections 😂 Although it is fun to have a little argument every now and then...
An interesting alternate take on an Apollo lunar landing! The Apollo Guidance Computer (AGC) is something that has always fascinated me. If it interests you as well, I highly recommend the following two talks about it: - "Light Years Ahead | The 1969 Apollo Guidance Computer" th-cam.com/video/B1J2RMorJXM/w-d-xo.htmlsi=4SnUAqGS69v39Dau (This is a detailed, but humorous, account of what the AGC did and what happened during the Apollo 11 descent done by a very knowledgeable young man) - "34C3 - The Ultimate Apollo Guidance Computer Talk" th-cam.com/video/xx7Lfh5SKUQ/w-d-xo.htmlsi=nfe4UJEE8xLyejv3 (This one is even more detailed and goes into specifics about how the AGC operates, including its command set! Probably most interesting to programmers.)
@@apollo12-apolloflightjourn11 Amazing, thanks so much for your work! I just want to ask, do you also plan to add all 16mm mags to the Apollo 16 flight journal channel?
It's funny.... 90% of the world knows Buzz and Neil.... Round up 10,000 random people.... Not one will know the names of any other of the guys that walked on the moon. Crazy.
to help those people here goes ..Neil Armstrong, Edwin Aldrin (11) Charles Conrad, Alan Bean (12) Alan Shepard, Edgar Mitchell (14) David Scott, James Irwin (15) John Young, Charles Duke (16) Gene Cernan, Harrison Schmitt (17)
@@KPL400 Nice summary. I remember the name Gene Cernan and Alan Shepard... But nobody and I mean nobody really can list off the others... off the top of their head.
Yeah, Armstrong and Aldrin could barely leave their houses without being mobbed. Armstrong could barely go out in public without security people for the rest of his life. Cernan and Schmitt could lead normal lives, go to the movies, go to the grocery store, etc.
This is 16mm film footage. By using the phrase "written over", it implies an assumption that this was video recorded on magnetic tape. Two entirely separate things are being mixed up here, but that is the way of modern information exchange. It doesn't have to be correct to be spread far and wide. What is likely being referred to as "written over" is referring to the tapes that had a recording of the slow-scan video signal that was transmitted during the moonwalk of Apollo 11. That signal was converted, live, to commercial TV format for live broadcast. The source signal was recorded on tape but it was not required again - until decades later when it was realised that the rather poor conversion process could be bypassed if those tapes with the slow-scan recording could be located. They never were. Meanwhile the story was passed around and distorted. The original Ektachrome film of this 16mm footage still exists, kept in a freezer in Houston. This is a high definition scan of that footage. Film and video are very different technologies.
@@apollo12-apolloflightjourn11 They used Ampex tapes at the time and they were very expensive. Indeed, it was the Slow-Scan images that were overwritten, not the converted images. Too bad because the Slow-Scan images were of better quality.
No, no one knows. It'll probably always remain a mystery. I'd recommend continuing to ask in comment sections of youtube videos. They're an excellent - possibly the best - source of important scientific knowledge.
An easy cocktail party answer is +250F to -250F. The actual surface tempetatures during Apollo 12 are difficult to find. Google is useless as it it often lists Quora, Reddit and Wikipedia as factual sources and then asks if you really meant ro ask about something else. I have a ton of printed apollo references, now I want to know what the surface temp was during that mission!
@@jamesgibson3582 All of the missions took place during the lunar morning (a day on the Moon is equivalent to a month on Earth). So suffice to say the temps were not extreme at either end of the spectrum during any of the landings. That was by design.
@@thewildcellist I totally agree on the timing and the reason, and for years....up until today, I never wondered specifically what temp Apollo 12 landing site was. I figured it would be a simple google query. Not so apparemtly. I do have a ton of printed books and I am pretty sure the temps for each landing were in an appendix of one of them. I appreciate your comment, now I am just fixated.
@@jamesgibson3582 got it. It's funny (and tragic) how so often what "should" be a simple internet search often is anything but. Good luck! Seems like those temps would be documented - somewhere.
after they land on the moon , they vent the remaining fuel in the descent stage. They get rid of it by letting it evaporate outside . This is to avoid any danger because working around a descent stage that still has fuel in it could be dangerous
Every landing was filmed with a 16mm film camera. They only had one such camera on each mission, for the landing this was installed on a bracket, looking out the window. The LM could not send a video signal to Earth during the landing: it didn’t have enough bandwidth to send video and high-rate telemetry at the same time. So there is no TV footage of the landings.
Are you asking just about the Apollo 12 mission? Yeah, there's a little bit more footage, but, not much. The TV camera burned out a few seconds after being moved to its tripod, which would have been the majority of the Apollo 12 footage (had it worked). But, yeah, as it is, they just have some of those 16mm clips, and photos. Ironically, they even accidentally left one roll of 70mm film inside the camera (still sitting on the lunar surface). So, not only does Apollo 12 not have as much video as was planned, but, even lost a whole bunch of photos also.
Not a conspiracy theorist, but are these communications altered? The communications between Earth and Apollo 12 takes about 1.5 seconds one way and there are many occurrences in this apparently uniform audio where the responses come in immediately, which would be impossible.
Yes you are, why are you picking this out? . this is a well done integrated video and audio that would have been tailored for general consumption., including removing no sound in the audio side.
@@chsyank No I’m not. I’m picking it out because it stood out to me. All I’m asking is if anyone can confirm that the audio was edited in the manner in which you suggest. It’s not a hard question. If you don’t know the answer then shush.
@@tubecated_development There are many examples but one is at 5:30 where Bean transmits “Roger. Copied. Plus 04200” and MCC replies immediately with no delay. Having listened to the rest I noticed that the delay only happens when Apollo 12 is talking to Houston, which would make sense if the recording of the transmissions was being made at Houston, which it was. So I think that’s what’s happening rather than audio edits. If you rewind to 5:20 when MCC transmits the 04200 info there is an appropriate delay before Apollo 12 responds.
Don't cite me but I think I remember from from the Apollo 11 "real time + 50y" event that the audio was synched at times. But this is not required most of the time, as each source recording was from a certain place, mostly Houston, so the communication delay is already on the record, effectively synched. So I would guess this particular recording here should not have needed any additional synching; it was as things looked and sounded to Houston and indeed, the actual events and sounds in the LM took place 1.5 s prior.
This is a recording of comms as heard in mission control in Houston. The only perceivable delay in comms would be when CAPCOM say something that the crew respond to. For example 8:57. Otherwise, CAPCOM's responses to the crew are real-time, as you would expect.
They build such a beautiful machine. a beautiful system and teams to match. How is it possible that they just threw it all down the gurgler? How did they pull away the support after all that beautiful work. and now standing by, watching... you've left Ukraine to wither on the vine. Who are you America? Who did you become?
I would have made a lousy astronaut after my anxiety attack about a successful landing and several barf bags later i would start worring about that rocket fireing and if it was going to get me the hell out of there 😊
I know you really want to believe that this huge and multilayered government conspiracy requiring the silent participation of tens of thousands of people to keep their mouths shut and tell no one so they could fool you somehow forgot to remember one of the most basic aspects of long distance radio communications, but the delay is there. 🤣😂
They're talking past each other @5:20 and @8:00. How could that have happened, when there's "no delay"? FYI, if you've ever been on a conference call with a delay, it happens all the time.
@@stephenh5944They’re talking past each other exactly BECAUSE there is this delay. You can experience it yourself with a simple Skype call. Happens all the time. So 🤷♂️
@SelwynRewes Thought not. Try explain this. Proof of Apollo fakery. Nasa official image number: AS16-113-18340 This is the famous flag salute jump photo of John Young, photographed by Charlie Duke. This even was apparently filmed at the same time by the TV camera attached to the Lunar Rover in the background. Let's play spot the difference: Pay attention to the top of Young's PLSS backpack, the triangular flap at the top which is unbuttoned and pointing directly upwards. In the video footage, this flap is fastened flat and not pointing upwards at all. These events didn't take place at the same time as claimed.

Yes, with a tiny fraction of the funding that Apollo had, they have gone "backward" (in the sense you're talking about). They went from getting 4.5% of the entire federal budget in hard costs, plus another 2% in soft costs and international support, almost entirely poured into one program... down to 0.5% of the federal budget, spread out over hundreds of programs. As for unmanned missions, yeah, they tend to be about 1/100th (literally) of the cost of manned missions, and, if successful, send back information for a decade or more, instead of needing to come back home after a matter of hours. But, Artemis is coming.
Kubrick was busy filming 2001: A Space Odyssey. This was heralded as the most accurate portrayal of space yet. But the 0 g and lunar scenes in that movie are faked, and it’s immediately obvious they are on Earth.

@@randyjohnson6845 Why would there be a crater?? Craters form from solid impacts, not from gas pushing it around 😂 Also dust settles fast on the moon because there's no wind to keep it floating when you switch off the thrusters. Use your brain.

There isn't an aerospace engineer on the planet who would expect craters to be dug by 2500 pounds of thrust out of a 20 sq. foot engine bell. Oh, but YOU do.

"and then he went to Russia and said no way to go threw ..." Funny, I can't find any reference to him either going to the USSR or saying there was no way through the belts. So it would be great if you could provide a source for this. I do see how he kept working for NASA in the 1960s and 1970s, helping them with preparing for Apollo and then a bunch of unmanned missions. "and then out of no where he said it's perfectly safe" Yeah, if we leave out your (currently) evidence-free claim that he said there was no way through the belts, there's nothing "out of nowhere" about him saying it was perfectly safe. Then there's the simple fact that the Soviets sent spacecraft through the belts themselves, so they had their own data to compare with Van Allen's. Should we be surprised that the Soviets had no problem with the idea of people passing through the belts?

Awesome! I was 14 when Apollo 12 touched down and your video brings back some great memories--thanks!
I think part of the excitement is having some ground to stand on, any kind of ground, after floating around in space in a tin can for several days!
Amazing technology for the time. Shame the US was unable to continue with Moon after Apollo, they had the brilliant brains to have made it to Mars many decades ago
The vertical assembly building could hold 4 Saturn V rockets, the plans were for 100+ launches. 1986 was considered the best launch window for a crewed Mars mission. Congress threw it all away, leaving only Skylab, and the flying brick aka shuttle which (technically) couldn’t really even reach earth orbit.
One thing, money (the Apollo program was a huge sinkhole that could not really last for ever); the other thing is that Mars really was considered, which led to the realisation that it would be practically impossible to put a live human there.
We were watching the news on the BBC, from our home in West Belfast and Patrick Moore came on to the tv, just before the weather came on. All excited he told the audience to rush out side and look to the West! And there was stage 2 of Apollo bright in the late autumn sky. It was 6:30pm.
In the words of Alan Bean "Outstanding" 🙂
I used to play a game called Moon Tycoon. Some of the audio from this conversation is used as ambient dialogue. Very interesting to hear familiar phrases dotted throughout

American ingenuity at its best. I love it. Awesome!!!.
Plus British engineers/scientists and astronomers. Without the British designed fuel-cells none of the missions would have worked.
research how much of it is actually american...
Who woulda thunk flat Earthers would be born 10 years later and dream up conspiracies of a Hollywood movie set?
Compared with Apollo 11 this recording makes it sound like they already had it down pat! Nothing quite like Apollo 11's first Lunar Landing.
Great video, i stared till the end with open mouth...
I don't see how you could watch this and listen to Pet Conrad and Al and Bean land in the Sea of Storms and belive the Moon Landing was fake. It's the real thing ! . Thank you for the video.
The faker people are completely devoid of any scientific or engineering knowledge and they didn’t live through it like some us did. They’re basically disaffected losers who think everything is a deep state conspiracy. Most of them barely have high school and certainly nine have any STEM qualifications. Therefore their opinion really is worthless. It’s like debating Shakespeare with someone who doesn’t even know the alphabet. It’s not even worth the effort.
No one with any degree of intelligence would think otherwise.
@@philfyphil not a single prominent astronomer, physicist or other scientist or engineer has ever cast any doubt on the moon landings.

A mistake they were unaware of at the time.
I had a tape deck and was able to record the landing off my radio. Lots of fun
Beautiful, spot on landing.

To the conspiracy theorists: where is your proof that we did not land on the moon? There is way more evidence that we, in fact, did land on the moon. Friggin mindless trolls.
They have no life. There's no reasoning with those who do not want to listen, change or learn anything new.

An interesting alternate take on an Apollo lunar landing! The Apollo Guidance Computer (AGC) is something that has always fascinated me. If it interests you as well, I highly recommend the following two talks about it:
- "Light Years Ahead | The 1969 Apollo Guidance Computer" th-cam.com/video/B1J2RMorJXM/w-d-xo.htmlsi=4SnUAqGS69v39Dau (This is a detailed, but humorous, account of what the AGC did and what happened during the Apollo 11 descent done by a very knowledgeable young man)
- "34C3 - The Ultimate Apollo Guidance Computer Talk" th-cam.com/video/xx7Lfh5SKUQ/w-d-xo.htmlsi=nfe4UJEE8xLyejv3 (This one is even more detailed and goes into specifics about how the AGC operates, including its command set! Probably most interesting to programmers.)
Great! Will you add the other 16mm magazines to this channel as well? Especially the one with footage of the eclipse.

Apollo 11 Descent: Film and LRO Imagery combined!
th-cam.com/video/YKXw_3Pblh8/w-d-xo.html
Fantastic
Never seen that before, shame the main camera failed for the moon walks.
I remember that when it happened. It was a real letdown.
Wasnt the original footage lost or written over?
This is 16mm film footage. By using the phrase "written over", it implies an assumption that this was video recorded on magnetic tape. Two entirely separate things are being mixed up here, but that is the way of modern information exchange. It doesn't have to be correct to be spread far and wide.
What is likely being referred to as "written over" is referring to the tapes that had a recording of the slow-scan video signal that was transmitted during the moonwalk of Apollo 11. That signal was converted, live, to commercial TV format for live broadcast. The source signal was recorded on tape but it was not required again - until decades later when it was realised that the rather poor conversion process could be bypassed if those tapes with the slow-scan recording could be located. They never were. Meanwhile the story was passed around and distorted.
The original Ektachrome film of this 16mm footage still exists, kept in a freezer in Houston. This is a high definition scan of that footage. Film and video are very different technologies.
Not only this is the wrong _Apollo_ mission to ask that about, it's about the wrong type of footage.
@@apollo12-apolloflightjourn11 They used Ampex tapes at the time and they were very expensive. Indeed, it was the Slow-Scan images that were overwritten, not the converted images. Too bad because the Slow-Scan images were of better quality.
Un logro increíble excelente 👍 de 🇺🇸🌍👌🌟
So does anyone know the temperature of the moon surface?? Is it hot or cold ?
No, no one knows. It'll probably always remain a mystery.
I'd recommend continuing to ask in comment sections of youtube videos. They're an excellent - possibly the best - source of important scientific knowledge.
An easy cocktail party answer is +250F to -250F. The actual surface tempetatures during Apollo 12 are difficult to find. Google is useless as it it often lists Quora, Reddit and Wikipedia as factual sources and then asks if you really meant ro ask about something else. I have a ton of printed apollo references, now I want to know what the surface temp was during that mission!
@@jamesgibson3582 All of the missions took place during the lunar morning (a day on the Moon is equivalent to a month on Earth). So suffice to say the temps were not extreme at either end of the spectrum during any of the landings. That was by design.
@@thewildcellist I totally agree on the timing and the reason, and for years....up until today, I never wondered specifically what temp Apollo 12 landing site was. I figured it would be a simple google query. Not so apparemtly. I do have a ton of printed books and I am pretty sure the temps for each landing were in an appendix of one of them. I appreciate your comment, now I am just fixated.
@@jamesgibson3582 got it. It's funny (and tragic) how so often what "should" be a simple internet search often is anything but. Good luck! Seems like those temps would be documented - somewhere.
What is the descent vent ?
after they land on the moon , they vent the remaining fuel in the descent stage. They get rid of it by letting it evaporate outside . This is to avoid any danger because working around a descent stage that still has fuel in it could be dangerous
thats all the footage they have?
There is a lot more
Every landing was filmed with a 16mm film camera. They only had one such camera on each mission, for the landing this was installed on a bracket, looking out the window. The LM could not send a video signal to Earth during the landing: it didn’t have enough bandwidth to send video and high-rate telemetry at the same time. So there is no TV footage of the landings.
Are you asking just about the Apollo 12 mission? Yeah, there's a little bit more footage, but, not much. The TV camera burned out a few seconds after being moved to its tripod, which would have been the majority of the Apollo 12 footage (had it worked). But, yeah, as it is, they just have some of those 16mm clips, and photos. Ironically, they even accidentally left one roll of 70mm film inside the camera (still sitting on the lunar surface). So, not only does Apollo 12 not have as much video as was planned, but, even lost a whole bunch of photos also.
Absolutely certain that Apollo 12 had Three man crew.. 👨🏼🚀👨🏻🚀👨🏽🚀..Alan Bean, Pete Conrad, and Dick Gordon😊
One was left in the orbiter, same as Apollo 11.
Not a conspiracy theorist, but are these communications altered? The communications between Earth and Apollo 12 takes about 1.5 seconds one way and there are many occurrences in this apparently uniform audio where the responses come in immediately, which would be impossible.
Example? Timestamp?
Yes you are, why are you picking this out? . this is a well done integrated video and audio that would have been tailored for general consumption., including removing no sound in the audio side.
@@chsyank No I’m not. I’m picking it out because it stood out to me. All I’m asking is if anyone can confirm that the audio was edited in the manner in which you suggest. It’s not a hard question. If you don’t know the answer then shush.
@@tubecated_development There are many examples but one is at 5:30 where Bean transmits “Roger. Copied. Plus 04200” and MCC replies immediately with no delay. Having listened to the rest I noticed that the delay only happens when Apollo 12 is talking to Houston, which would make sense if the recording of the transmissions was being made at Houston, which it was. So I think that’s what’s happening rather than audio edits. If you rewind to 5:20 when MCC transmits the 04200 info there is an appropriate delay before Apollo 12 responds.
Don't cite me but I think I remember from from the Apollo 11 "real time + 50y" event that the audio was synched at times. But this is not required most of the time, as each source recording was from a certain place, mostly Houston, so the communication delay is already on the record, effectively synched. So I would guess this particular recording here should not have needed any additional synching; it was as things looked and sounded to Houston and indeed, the actual events and sounds in the LM took place 1.5 s prior.
Спасибо за Историю!
Incredible the quality of comms they have no delay between the moon and the earth
The delay was clear…
You’re trolling
Quite clearly a delay of about 2 seconds where they occasionally step on each others transmissions. Exactly as expected.
This is a recording of comms as heard in mission control in Houston. The only perceivable delay in comms would be when CAPCOM say something that the crew respond to. For example 8:57. Otherwise, CAPCOM's responses to the crew are real-time, as you would expect.
Apollo 12 was hit by lightning shortly after launch. Fortunately, no harm was done
They build such a beautiful machine. a beautiful system and teams to match. How is it possible that they just threw it all down the gurgler? How did they pull away the support after all that beautiful work. and now standing by, watching... you've left Ukraine to wither on the vine. Who are you America? Who did you become?
Absolutely amazing!
Incredible stuff! but you can't tell that to Bart Sibrel he thinks the astronots are a bunch of liars🚀

There is a delay as explained in the thread with 20 plus comments. Please read that and ask a question if you still don't understand.

Nasa official image number: AS16-113-18340
This is the famous flag salute jump photo of John Young, photographed by Charlie Duke. This even was apparently filmed at the same time by the TV camera attached to the Lunar Rover in the background.
Let's play spot the difference:
Pay attention to the top of Young's PLSS backpack, the triangular flap at the top which is unbuttoned and pointing directly upwards. In the video footage, this flap is fastened flat and not pointing upwards at all. These events didn't take place at the same time as claimed.

Yes, with a tiny fraction of the funding that Apollo had, they have gone "backward" (in the sense you're talking about). They went from getting 4.5% of the entire federal budget in hard costs, plus another 2% in soft costs and international support, almost entirely poured into one program... down to 0.5% of the federal budget, spread out over hundreds of programs. As for unmanned missions, yeah, they tend to be about 1/100th (literally) of the cost of manned missions, and, if successful, send back information for a decade or more, instead of needing to come back home after a matter of hours. But, Artemis is coming.
Never happened.

Kubrick was busy filming 2001: A Space Odyssey. This was heralded as the most accurate portrayal of space yet. But the 0 g and lunar scenes in that movie are faked, and it’s immediately obvious they are on Earth.
The Apollo videos show the astronauts moving in perfect 1/6 g gravity, which is only possible if those videos were recorded on the moon.

I do see how he kept working for NASA in the 1960s and 1970s, helping them with preparing for Apollo and then a bunch of unmanned missions.
"and then out of no where he said it's perfectly safe"
Yeah, if we leave out your (currently) evidence-free claim that he said there was no way through the belts, there's nothing "out of nowhere" about him saying it was perfectly safe.
Then there's the simple fact that the Soviets sent spacecraft through the belts themselves, so they had their own data to compare with Van Allen's. Should we be surprised that the Soviets had no problem with the idea of people passing through the belts?
