Neil Armstrong's biggest fear about the Apollo missions was a solar occurring during the mission and although none of the missions was affected by such an event they were lucky through timing rather than anything else. This video looks at what might have happened if they might not have been so lucky and how we are trying to mitigate such effects happening on the up-coming Artemis lunar program in 2024.

A correction is in order as I said the gateway program was cancelled, this is not the case and it is due to be in place by the time of the Artemis program in 2024.
Also, a 10-Gy whole-body dose of ionizing radiation would result in almost certain death within 24-48 hours, with or without a bone marrow transplant and supportive care. Anything above 8 Grays is generally regarded as invariably fatal, and 10 is definitely in that territory. A dose of 4-6 Grays is generally where doctors and specialists try to do intensive interventions like colony stimulating factors, marrow transplants, and so on. Anything in the 10 Gy range would probably just be met with palliative care-- I believe that one's chance of survival at that high of a dose is something like less than one tenth of one percent, and that's *with* aggressive interventions. Then again, a lot of the events that have informed our medical knowledge of acute radiation sickness have been multiple-casualty in nature, Chernobyl, Hiroshima/Nagasaki, Castle Bravo fallout, and so on, meaning that such medicines were maybe reserved for those who the doctors thought had the best chance of survival. If it were just a one-victim event, maybe they'd get the kitchen sink thrown at their ARS, I just don't know.
Just thought I'd add in that thought about 10 Grays being a tad more serious than you made it sound, thanks for the great video
That's good news
Came here to ask since I thought I totally missed it. Glad it's not cancelled.
Thanks for the correction and your awesome content, learned so much because of you.
That's unfortunate. The gateway program is a waste of effort. Spacecraft should be able to go directly to the Moon without any steppingstones. The Moon itself is the practical steppingstone for missions further out.
@@MrVillabolo Well, in order to prep the Moon to be that stepping stone, you might need the Gateway as an interim step, no? But in all seriousness, there are so many reasons why all the manned missions put on or designed for TLI have been 2-spacecraft (orbiting tug + lunar lander)-- If you need to land your whole stack on the Moon, that means you need to carry enough fuel to lift the entire stack off the Moon again, and you need to have the whole stack certified for the entire complex process of launch, TLI, lunar landing, lunar ascent, and TEI, as well as being itself certified for reentry or having a second capsule anyway for reentry. It is orders of magnitude cheaper to break the stack into discrete pieces, each of which is designed for the environment and workload of each step in the mission. Imagine if you had to have a command and service module (CSM) that was designed not only to accomplish the big navigational burn to get back to Earth (TEI) (The reason I didn't include TLI is because the Apollo missions used the S-IVB third stage to perform its TLI burn, and I assume that Project Artemis will also use a stage to accomplish it too), as well as keep the crew safe in deep space for a week or more, and carry enough consumables for both the trip there and back, but ALSO be rigorously certified for lunar landings and ascents, as well as moderate-to-long duration stays on the lunar surface. Yikes. I know we've come a long way in materials science, engineering, rocketry, and a whole bunch of other things, but even to a casual observer this seems like an unrealistic vision. Also, such a spacecraft would almost certainly be expendable (i.e., not re-usable), so this ship, which would almost certainly be the most expensive spacecraft ever built, would be thrown straight into the garbage can right after it performed its duties.
I'm not arguing that it's impossible, I just think that it makes so much more sense to do things another way in terms of a number of variables that it would simply never happen. However, if it did, it would be cool, not gonna lie.

One of my hobbies as a child, which is now my career, was programming our home computer.
The first computer we had, an Acorn BBC Micro Model B, came with a mountain of detailed programmers documentation and reference material.
Everything you needed came with the computer.
However, our _second_ computer was an Acorn BBC Archimedes A3000
This came with practically no programmer's documentation.
So I could never really program it beyond what was the same between the two computers.
Pre-Internet, so you're screwed, it's impossible without spending hundreds of pounds on documentation.
And this ain't even know what documentation you should choose.
That's what it was like back in the 80s and the start of the 90s, you just wouldn't any information
carzy how much of early space exploration was basically just russion roulette. those astronauts & cosmonauts were some brave sob's.
No different than aviation of the time. We are just surrounded by pussies now.
True heroes they were.
There’s one above me.
That's what exploration is. The first explorers who sailed the high seas, without knowing what they were going to find, were also basically playing Russian roulette. Same thing can be said for those who explored Antarctica and mountain tops. Even when we were hunter-gatherer, it took incredible bravery and courage to explore unfamiliar new lands, with all the unknown dangers that could be there.
@@ronaldtartaglia4459 I guess we value human lives more these days, which in itself surely isn't a bad thing? Back then we risked human leaves for silly things like the cold war.
When I was a tiny little kid in the 70s watching James Burke talking about the Apollo "moonshots" on British TV, I thought the Van Allen belts were what astronauts used to keep their spacesuit pants from falling down! 😶

The Apollo astronauts were tough and brave guys. They knew the risks and accepted it with class and preparation.
It's no surprise all kinds of conspiracy crackpots and flatearthers reject the achievements of Apollo program because they have not achieved anything significant themselves.
Thank you C.D. for bringing the light to this dark place called CZcams.
It appears you don't understand what a conspiracy theory actually is.
A conspiracy theory is a theory that involves a conspiracy.
A conspiracy is when two or more organisms (the 'conspirators') work together for some goal.
Conspiracy, collaboration, collusion, cooperation.
That's it.
Conspiracy theory does not mean ridiculous theory (a theory that is ridiculous) or false theory (a theory that is false).
A conspiracy theory may be good theory, offering value.
A conspiracy theory may be bad theory, offering no value.
So what is it that makes it a conspiracy?
The relevant question to ask is, are there two or more people involved?
If yes, then it's a conspiracy, collaboration, collusion, cooperation.
If not, then it is not a conspiracy.
A baseball team conspires to beat their opponent.
The "official US government story" about 911 is a conspiracy theory; there were more than one hijacker involved.
Don't conspire with other idiots to keep the status quo.
Instead, conspire with intellectuals to change the world to be a better place to live.
Conspiracy, collaboration, collusion, cooperation.
All REQUIRE 2 or more people.
If you think a theory is a conspiracy theory, ASK YOURSELF, "WHO ARE THE CONSPIRATORS?"!!!
The term, conspiracy theory was weaponized by the CIA in the mid 1960's during Operation Mockingbird, in which agents infiltrated corporate mainstream news outlets.
This sewage was then spewed on a public lacking the cognitive abilities required to vet information.
@@ashleywallace1165 Thank you for that very articular and equally meaningless comment, but please notice I did not use the term "conspiracy theory" in my comment above.
In the context of the topic here, people who believe moon landings were faked deserve pity or even resentment. Calling them conspiracy crackpots is not an insult, but an observation. It's the moon landing deniers who insult the astronauts and all the people who worked in the Apollo program.
@@ashleywallace1165 Even if you're technically correct about the literal definition of "conspiracy theory," you know what the original poster meant by the term. It's evolved a new, common meaning in our vernacular, CIA-inspired or not. I don't think every conspiracy theory is dumb, and they're fun to talk with your friends, but the Moon Hoaxer cretins you see in every comments section on CZcams for space videos are so god damned obnoxious.
@@ashleywallace1165 So which conspiracy theories do you fervently cling to?
@@ashleywallace1165 Nicely put.
Too many conditioned failures lack the cognitive abilities to vet information spewed on them 24/7 by the corporate media.
One minor inaccuracy. The reason we see the aurora over the magnetic poles is that the magnetic field is closer to the Earth there. The particles deflected from the magnetosphere are invisible...and the deflection is also invisible. We see light from particles that were not stopped by the magnetosphere and crashed into either oxygen or nitrogen atoms, which then glow after absorbing the energy and becoming energized plasma, like neon tubes do. The particles are not "funneled" there.
The particles are guided along the magnetic field lines towards the poles, a fraction of which are actually guided into the atmosphere. Although funneling is technically not correct, the shape at the poles does resemble a funnel
I think he was trying to simplify the language for everyone to understand. If he went into detail with every single point, the film would last hours and would be very boring.
Just the start of his inaccuracies.
@@stevesmith7839 Simplification at the cost of real science.
The Apollo mission could also have realigned the spacecraft so that the CM and LM would be in the shade of the Service Module pointed away from the Sun. The SM engine, food, assorted supplies and water/fuel tanks and batteries would take the brunt of the CME while the crew took shelter in the LM.
That's not how physics and astrophysics work

one minor correction, NASA's Gateway project is not cancelled, it's just not on the "critical path". We're still working on it at JSC
gateway to nowhere, sad to say
The gateway hardware can be made obsolete by using a modified starship that can dock multiple earth-moon shuttles and landers. And be much cheaper. Once that idea has fully settled into the heads of the decision makers, the outcome seems simple to me.
There are several projects working on generating plasma and using magnetism to wrap it around spacecraft in a bubble big enough for spacewalks. Yes, a real life force-field.
Apollo had a small fraction of the power needed to do this.

@MichaelKingsfordGray what in tarnation do you mean?
Rather than a full spheroid of water shielding around the entire craft, would it not be more practical to have a limited area, and quite literal, partial shield of all the craft's water reserves to shelter the crew behind for a few hours?
The LEM spun in what was referred to as a "barbecue roll" to avoid overheating from the sun.
That water shield wouldn't work if in just 1 spot.
Good idea though.
@@conradmcdougall3629 ...so my old waterbed won't cut it? It's been through so much I thought a solar flare would be easy peasy.
When fuelled Starship will have a lot of liquid methane onboard...something that is also packed with Hydrogen.
You can't shield behind something against Galactic Cosmic Radiation, it comes from every direction and the Solar radiation, well read about what happens when it encounters the materials of the craft. You can't just duck behind something and be safe.

I just can't wrap my head around the fact some people think it was faked.
Yeah the camera team was already waiting on the moon when they landed on there.

Just found this page, excellent video and thank you for providing additional information regarding the solar flares and dangers of solar radiation. Looking forward to watching more of your videos!!
In the 1990s I used to climb the large Cascade volcanos. The routes frequently went under glacier icefalls. This is where a slow moving glacier hits a cliff and randomly dumps huge chunks of ice. When traversing underneath one, you saw these chucks randomly scattered. Also, eerily when camped out on the glacier you would here thuds from these icefalls.
Like space radiation, it is a numbers game. You quickly passed underneath these ice falls and prayed the random event would not happen at that moment.
Surely the best way to provide shielding for a long-term base on the moon would be to bury it under half a metre of regolith.
Thank you so much for your videos Paul. I enjoy watching every video you make.
Watching this video once more... It is a great explanation with a very wide breadth, concise in nature while being detailed at same time.
Thank you Mr. Shillito, it is highly appreciated...
I have often wondered how the 1st Apollo mission dealt with the Van-Allen belt around Earth. Now I know that there is no escape from it but instead one must navigate through it to make it to the Moon and other places in the solar system. Odysseus had Scylla and Charybdis and we have cosmic radiation in myriad forms. Thank you for showing the extent of the effects of the solar flare from the 50s here on Earth. That scale of power is unimaginable when you think that it caused over 4,000 magnetically-triggered naval mines to explode within a short time of each other. Satellite circuitry was cooked, solar panels were hammered by charged particles that essentially aged them, digital communications were extensively disrupted. It's an example of how far we have to go scientifically to understand the basic mechanics of the universe...not even that, just stars as a beginning. It's humbling under no uncertain terms but awe-inspiring at the same time. It's why I like Star Trek (original series)-- their slogan wraps the whole idea up by the phrase "to boldly go, where no man has gone before."
Appreciate your great work. This is my favorite channell that never fails to align with my interests how delightful it is to have such a great and knowledgeble narrater, you are proof that Gen X people are our greatest hope for the future.
One thing I learn is we are not much better prepared for space travel today than we were back then.
I hear all these dreamers caught up in space X hype saying humans will have a Martian colony in X years etc. People lose sight of reality so easily.
I just LOVE this channel!!! The information is so extraordinarily and fantastically presented, editing, and narration are superb!!!
Thanks for the great video!👍🏻👍🏻😎😎
Superb clarity of explanation on this huge issue for space travel. Loved it.
The SI unit is Sievert by the way, not Rem. And of course, Gray is an SI unit, but only for raw radiation which does not give the full physiological picture unlike Sievert. So there is a curious mixture of non-SI and SI units in this video, although, at least for Rem and Sievert, it is easy enough to convert them into each other.
As an official radiation exposure worker (airline pilot) my monthly, yearly and life long exposure is measured in Sievert of course.
Did they use Sievert in 1969? If they used Rem back then quoting Rem makes sense.
Could the type of radiation they received in space be more dangerous than a slow & steady dose received by nuclear workers?
Most of the Apollo astronauts had heart problems in later life from their radiation exposure.
@@jbmurphy4 ...most American old men has heart problems. Be strange if they didn't. ^^
@@TurinTuramber that's true, but the apollo astronauts had a higher rate of heart problems due to radiation damage that disrupted the production of some important enzymes.

12:51 Did I miss the memo that Gateway was cancelled? NASA finalized the contract for HALO like last month.

I was wondering the same thing. The last I heard, it was "off the critical path", meaning that Artemis would proceed without waiting for the station be be built... but the intention was still to build it. That's pretty close to "cancelled", but not quite the same.
@@simongeard4824 Right, but with the now announced delay in building the xEMU suits I could see them coming online about the same time
Wondering the same haha, Gateway wasn't canceled at all! Maybe he confused it with the Constellation program?
I had the same thought.
it seems like it wasnt that long ago that spacex had tendered the dragon xl for resupplying the gateway.
I do believe it will be cancelled though as it will be seriously expensive to build and resupply. Unless Nasa give spacex sole rights to assemble and resupply the gateway and we all know their competitors wont let that fly..

The one way to get the point across the people funding you if they don't care about human life. Stop appealing to their hearts and appeal to their wallet.
Since there is nobody sitting in a satellite, the damage it causes to electronics is all that matters for that matter - space isnt just about astronauts. Its fair to point that out, because more people on earth depend on the cloud of sats above us than there are people up there. And make no mistake: working communications and sat nav protect and literally safe hundreds of thousands of lives on earth every day. Watch everything go down the shitter if a flare takes out a large chunk of satellites in our day and age...

"Who did" your shirt in this video? I appreciate the size of the space objects.
great work Paul, much more detail and science than you get on those dummed down channels on tv
The Carrington event, on September 1-2 1959. blew the higher voltage communication lines carrying the morse code communications, by inducing currents in these long electrical lines. There was a similar event causing a blackout some years back, when the power lines running from northern Quebec, were similarly affected. Of course, this just tripped the large numbers of relays all along the line instead of actually frying the system.
Shouldn't Galactic Cosmic Rays be GCRs instead of GSRs?
I could be wrong, but I think he is actually referencing this looking at the animation he used:
en.wikipedia.org/wiki/Gamma-ray_burst
Which mean he should have used GRB in that case
Yes I think so - I searched for GSRs but not a recognised acronym

Outstanding content as always. Thank you Paul.
good one...lots of excellent information
I like your presentation style. Pacing is good, scripting is good. Consistency is flawless (which as a business nerd is a fantastic quality to see in anyone). You do good work.
I remember a cheesy made-for-TV movie from my childhood about the first lunar colony surviving a major solar flare, and a pair of children shielded themselves from the radiation by hiding between large water storage tanks. Turns out it was called Plymouth and it aired on ABC in 1991.
In fairness depending on tank orientation that is an excellent strategy since water is one of the best insulating materials against radiation.
I lived for 10+ years within 100' of a nuclear reactor with a water/fuel tank between us. I received less ionizing radiation during that period than a person who likes to sunbathe on the beach in the Summer for the same timeframe.
Water and, especially, hydrocarbons make for superb radiation shielding. Russian submariners I interact with curse the designers of their boats for not incorporating the water and fuel tanks into the reactor shielding. I lament the number of my brothers in the submarine community who suffer today for that shortfall..................
So we need water and hydrogen rich plastics.

That was an awful lot of luck, for all those missions.
It was based mostly on taking calculated risks, not relying on luck. Fortunately, the sun is not on killing spree all the time like it happened in August 1972.
All it took was not having bad luck. I bet the odds of a solar flare during a moon mission was much less than 50%.
How many solar flares a year are at the level of being deadly to astronauts? How many days in a year were there astronauts in dangerous areas of space?
OK, I did a bit of research to come up with a sense of the odds. The 8 missions to the moon occurred over four years. So about two a year. Most missions were a week or less. Apparently there are about ten "X class" solar flares a year. I think these are the ones that are the most dangerous to astronauts.
So a mission to the moon is kind of like playing Russian Roulette with a 52 chamber cylinder gun. While that's certainly not a safe activity, you don't have to be extremely lucky to survive. You just have not be mildly unlucky.
Still, I'd volunteer to go on next mission to the moon if they'd take me.
hallelujah... I'm rightfully overwhelmed by your explanations, Paul!!
Excellent video. Thank you.
So consistently interesting and well made
5 rem at the time. Modern radiation workers have a limit of 2 rem in the US
pffft. 2 rem?? pussies. I bet they don't even smoke while they drink and drive. disgusting.
Being on the moon is MUCH safer than travelling to the moon! You have 50% of radiation reduction just from the moon (which is quite dense) itself. That wasn't mentioned in this video.
Long time ago since I've read these figures but I think radiation in space increases by 260x, on the moon it's 120x, and on Mars it's 88x (the Martian number I'm pretty sure about, however these figures may have changed since they were first calculated)
But that also means you might need to get to the “dark side” of the moon. I think those numbers are averages, and moon’s magnetosphere is rather tiny.
@@AaronShenghao I wouldn't think so, like if putting a metre or two of soil above your head gives adequate protection against most things, then a whole "planet" at your feet is practically a guarantee. The only thing I can think about facing Earth vs being on the far side of the moon is occasionally getting caught in its tail (ie it's magnetosphere)
@@AaronShenghao The 'dark side' of the moon is not dark from the sun. it is dark from the earth, as in faces away. When the moon is in front of the earth, as it is during a new moon phase on one side of earth and maybe even a solar eclipse on the other (but not necessarily), the 'dark side' is in full sunlight. This is a common misconception.

Positively astounding. Facets I had never even considered while playing Kerbal. I used to think history was full of more idiots than our current period. I had a sense of progress at least in a social sense. I am so disappointed in ourselves.
really nice episode. thankyou!
Great video. Thank you for making.
When you say there is "essentially" no atmosphere does that mean that there is a hint of a lunar atmosphere?
I read that there actually is a very slight wisp of atmosphere on the Moon, so thin as to be negligible.
Some particles floating above the surface would make a very low density atmosphere. That's just what I thought of. Particles of rocks and sand whatever is on the surface
Guess it depends how one defines atmosphere?
There are gas particles. If you want to call it an atmosphere it's trillions of times thinner than Earths.
As a matter of fact, in lunar soil, you can find oxygen that originated in Earth's atmosphere, as that oxygen is part of the exosphere of the earth. Every low earth orbit satellite, including the ISS, actually have thrusters as they experience very small drag from gases from the exosphere and thermosphere, which with prolonged exposure, would bring them down eventually.
The 3 kill shots CMEs from the Sun in July were nothing to laugh about and right up there with July 23 2012 CME event that could have burnt this planet to the ground within 6 months if the CMEs multiple burst were timed a few hours difference.
Just like class and intelligence never made it into your world.
fantastic vid, bravo
Amazing video as always!
Curious droid posting Apollo stuff, time to spark a blunt real quick
::passes you the bong::
MAY AS WELL JUST DO HEROIN!
@@drmantistoboggan2870 haha what the...? calm down mom
@@ScumfuckMcDoucheface ITS THE SAME THING!
@@drmantistoboggan2870 umm, no? haha no, it's not?... having smoked/snorted/injected many many ounces of heroin and smoked/injested many many pounds of marijuana... I can indeed declare that heroin and marijuana are in fact different things... I promise. haha
Welp I'mma get my comments in ... Video is 👍 great... Great 👕 shirt
Such terrific content!!
Very interesting loved that Paul 👍
You don't have to worry about solar radiation when you're staging the moon landing from a Hollywood film set
Meanwhile, the US government was in cahoots with the Soviets, who could have easily called it a fake. What next, are you going to talks about the Reptitlian, Grey, Hollow Earth, Shadow, Cloud people who rule the earth?
Go away
Even as we speak, NASA is secrectly preparing to get a replica Apollo 11 LEM base, plus flag, etc onto the moon, so that it can be 'found' there when the first Starship lands. Although, come to think of it, it would be lot cheaper just to use the old film lot and borrow a spare Starship off that nice Mr Musk...
@@paulhaynes5029 you mind lending me that crystal ball when you're done with it?
@@colinsouthern you missed my (perhaps too subtle?) sarcasm.
My solution being an expert in this field is fly at night then you won’t have to worry about the sun, simple can’t understand why nasa didn’t think of it, byee
Another excellent video....Thanks very much......!
Excellent post, CD. Thank you.
Its a sad day that Curious has to account for flat earthers in his presentation of space travel, but, alas, they seem the loudest (and thankfully) minority. Good video as usual Curious Droid🖒
Hey why not they are fun to beat with some cold hard scientific facts.
Flat Earthers are different from Moon Landing is faked conspiracy theorist. Not that I agree with any of them. Just pointing out while some may believe in both conspiracies, they don't necessarily believe in both. Flat Earthers are the worst since that is easily disproved by looking at the stars in the night sky (Polaris is a the easy one to disprove their theories). Apollo landing conspiracy you have to provide more facts to before they realize they are just dumb internet trolls.
@@jimmym3352 Do flat earthers think the moon is flat as well then?
@@paulhaynes5029 The difference between a flat earther and a moon hoax conspirasist is the model of reality they believe in. Moan hoax believe in a spherical earth, their argument is that we did not have the technological capability to land on the moon at the time.
A flat earther denies all reality and insist that the earth is flat. Most them use the moon hoax conspiracies to hedge the arguments.
@@rickyecook59 its not that i want people 'thinking like me' - i want people to stop believing in nonsense. Trust science and not flat earthers on youtube or antivaxxers etc. The fact that you're defending them kinda makes you the odd one.
Why do the non-believers even believe that the van Allen belts exist? Isn't it ALL a conspiracy? Lol.
Very intersting! I've learned a lot, thanks!
Thank you, Paul, for the wonderful explainer about space radiation.
In b4 flat earthers.
Turns out space is dangerous.
very, very interesting and informative- I had heard of this van allen belts etc. but did not understand the hazard presented. thx.
Great video and shirt. Always look forward to your uploads
