Space Educator’s Handbook: The Spacesuit
er.jsc.nasa.gov/seh/suitnasa.html
“Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen from sea level to about 75 miles up, where space begins. At 18,000 feet, the atmosphere is half as dense as it is on the ground, and at altitudes above 40/000 feet, air is so thin and the amount of oxygen so small that pressure oxygen masks no longer do the job. Above the 63,000-foot threshold, humans must wear spacesuits that supply oxygen for breathing and that maintain a pressure around the body to keep body fluids in the liquid state. At this altitude the total air pressure is no longer sufficient to keep body fluids from boiling.”
Apollo Lunar Suit
airandspace.si.edu/exhibition...
“This space suit was worn on the Moon by an Apollo 15 astronaut in 1971. Moon dust is still visible on the legs and boots.The space suits had to meet all the astronauts' life-support needs. Backpacks (left on the Moon) provided oxygen, temperature and humidity control, suit pressure, and power for their communications and data display systems. This suit, made of 22 layers of several different materials plus a 3-layer undergarment, also protected them against extreme lunar temperatures and micrometeoroids.”

"there is a problem that without gravity feces don't necessarily separate from the buttocks"...oooh boy
“Can someone get me the scraper?”
Pretty sure thats how the Houston catchphrase. Came about..
Houston, we have separation. Well, not quite, I've got doodie stuck between my cheeks.
Star Lord don't need a suit.
Aquins Varghese u would die in space without a spacesuit if u go to space without spacesuit u eye gonna explode
Starlord is to badass for a spacesuit. But what about Taser face? Or Scrotum head?
(People who saw Vol 2 know what I'm talking about)
Aquins Varghese 😂
Jerome Productions Its not funny.
@Neromare Works what the hell! i just woke up from mt sleep to see someone correcting me
Why do we feel safe under our blankets
Lol so true
Interesting dialog... Pressure is generally measured in Torrs. Earth pressure for example is around 760 torrs while lower pressure is well - Less (a lower number). Nasa tells us the vacuum of space is one level less than absolute lack of pressure. Such a vacuum is more than enough to CRUSH (implode) a 1/4" thick steel tankard (think fuel truck used to fill the tanks at your local gas station).
I would like to know just WHAT materials the space station and space suits are made of which can withstand such external forces which would easily CRUSH a heavy gauge STEEL tank?
You don’t understand pressure. A steel tanker crushed because of the pressure of the air on the *outside.* When there is a near vacuum and some small psi on the inside of something, it inflates a little but no more. Especially if the material is strong, like Kevlar.
"A Kind of Magic" Queen has wrote a song explaining this phenomena
thank you for finally answering the question how astronauts scratch their nose while on EVA
Lack of oxygen becomes a serious problem well below 40,000 feet. 25,000 is easily enough to render a person functionally unconscious. The FAA requires supplemental oxygen use for pilots in unpressurized planes above 12,500 feet because experience shows that pilots mental function becomes seriously degraded at that altitude. Experts recommend oxygen as low as 10,000 feet for pilots, specially at night, because night vision is one of the first things to go.
Can anyone tell me how these suites or the Apollo suites protected the Astronaut from the solar radiation, charged particles, gamma rays, Ultra-high-energy cosmic ray, C.M.E, and the like while on the moon and on the trip to the moon? I am really wanting to know how that all worked.
Not to mention the total vacuum of space that should tear the suit apart and suck out the human through the thin visor 😂
Shhhh....CZcams now censors all content questioning the moon landing.
they didn't because they never went and BTW it's impossible as far as 'science' knows ----
Nasa magic dust
Can you explain how it works, Cooling, water and power, explain all that pack that they have
2:20 Amy is cute as fuk.
At 1:20 it's very interesting that you cut the shot right here because in the full original version from NASA it continues to show the astronaut turn his head to the left along with the full helmet 90 degrees. With these particular helmets that was impossible as the helmet was attached directly to a non movable ring and therefore could not swivel. Because of the strange appearance of this space walk and the total error of the helmet swiveling many think it was not authentic. Judge for yourself when you can find the complete video. Just search for the first American space walk and also investigate the helmets used for that flight.. Hmmmmmmmmm ... if this video wasn't cut at that exact moment you could have seen the anomaly.
You were probably watching some hokey video from a crazy conspiracy theorist who doesn't believe on engineering science. At this point it's just funny.
The picture at the 2:00 mark answers the question about the boot prints on the moon not matching the space suite in the museum.
WOAH, BOEING SPONSORED YOU!?!!
Yeah
So let me get this straight🤔
At 1.3 Billion feet above the Earth these suits pressurized for a vacuum environment, oxygenated, dehumidified, exhausted, they were filled with electronic communication devices, had portable water system to hydrate, had cold water electric pumping system to circulate cold water to cool bodies for daytime temperatures on the moon of 225°F and electric heating coil systems to heat bodies for extreme cold temperatures of -280°F at night.
All this running on small 1969 DC batteries in a backpack for a 20 hour walk on the Moon and a 8 days mission in the LM.
Yet in 2019 my Dewalt 18V lithium battery screw gun won’t last a afternoon on a 98° day building a deck in my backyard.
And somehow the lunar module also stayed cool with daytime temperatures of 225° and hot with nighttime temperatures of -280°F with a small AC and heating systems running on 1969 batteries when my 5 ton 2019 home AC unit can’t maintain my house at 75° when’s it i’m 98° outside.
And let’s not forget all the technology was running on 32 kilobytes
😆😆😆🐑🐑🐑🐑🐑
The logical fallacies are numerous.
They brought tons of batteries and exchanged them out. I don’t see what’s not believable there.
They were never there at night, only in the day. And the suits were white. White is white because it reflects all light. Black is dark because it absorbs light. The heat on the moon is from the solar radiation. But because they are white, they reflect the radiation. Sure, some gets in, and they have water cooling systems to help with that.
And it only takes relatively simple math surprisingly to get to the moon. All you have to do is figure out trajectories and how x amounts of force will affect them.
@LGD 4033 huh?
Gemini walk at 1:18 if u watch the entire clip of that walk from the original vid, the astronaut turns his head.. the helmet swivels on it's latches. Someone explain that one...
Ok czcams.com/video/hoCnS9oFSDs/video.html
Gemini suits have helmets that swivel. Simple as that.
@@jakemckee1923 so they have a neck strap that swivels the helmet?
Thank you so much for not answering my question at all. Have a nice day!
and how do space suits protect astronauts from radiation? Why don't they use the same thing for building sarcophagus around chernobyl and in other applications?
gurl, this new hair looks so good on you!!
Is there some sort of gelatin lining that can be placed in the upper portion of the suit that will create a seal so that the lower portion don't have to worry about oxygen. Then you can calculate in the natural suction of space towards the bottom half to suction out the poop/pee in some way. By adding some valves in the suit?
Or like if inside of the suit is consist of a gel like material that'll act as a membrane(of course they will have to be naked when wearing the suits) then create some sort suction mechanism wether natural or mechanical down below. To suction the poo out as the person poop.
i love amy
+CONTRA i love it when a woman says pee and poo
Great photo of Amy in big space suit! haha.
love the fringe
i love her
I love how you did your hair Amy. :3
How on earth can it protect them in a vacuum...
mark Draco it's bullshit bro
Not how on Earth, how in space :-) The suit is pressurized to about 3.7psi of pure oxygen. On the ISS, they have to gradually go from atmospheric pressure down to the pressure of the suit in the airlock.
My3dviews I don't think you've seen a vacuum in action
Sad Boy A vacuum is just zero air pressure. As long as the suit is strong enough to hold a pressure differential of 3.7 psi, it will work. NASA does have vacuum chambers to test spacecraft and spacesuits.
Space suits is 33 in Pythagorean numerology. And Space helmet is 44 in Pythagorean numerology.
Space diapers...
I saw Amy on tv lol. So she's a historian. Please do a video long that D news!!
If you watched the episode of mythbuster when they tested a myth that an old fashion diving suit lost all pressure and the body person inside the suit was forced into the brass helmet if you saw that episode you have an idea of what would happen if a space suit lost pressure
Thanks Amy! (Thumbs Up!)
hello d News I love you guys! !!!!!
Did Amy change her hair? It's nice. Look nice. Also keep up the good work guys, loving the content thats made. Also Hey, hey, hey!
its only a matter of time, what will happen when one gets hit while in space say, astroid, space junk, meteor, something that cuts into the suite. eventually it will happen, what steps have been done? what actually happens? will that person survive?
I find it amazing that, out of the few comments here, the majority have nothing to do with the video's topic.
amys channel is amazing
Most interesting suit ever flown? Went to the mile high club so the bottom half of my birthday suit
So what do they do if they get a really bad itch on their backs?
some say Apollo mission was fake and was made in an studio
I love your hair! :D
Before this video I'd never mentally 'fleshed out' the challenges of taking a dump in orbit. Fascinating. I'd want a super sized wide-mouth two liter in case I had 'sloppies' one morning. Hell, maybe it would just be easier to shot in a diaper. I wonder if their diets are conducive to poops with cohesive properties. Huh.
That thumbnail doe! 😂
I like how the mic makes a D for D news.
Do "How contamined is tuna really regarding harmful substances?"
Otherwise great channel.....
The Velcro XD
You can pee and poo in them?! That's it. I'm sold
+Marcelo Jorge They're just wearing adult diapers. I'm sure they still try to avoid going. Nobody wants to marinade in pee and poo if it can be avoided. Or at least I assume that the cross section between people who enjoy that sort of thing and the people who make it into the astronaut program is likely to be non existent.
Where will you fall down to moon by moon gravity when traveling to the moon? How does your head tell you which is up or down when you are at the moon gravitation field, when you are traveling from the earth to the moon? You are traveling up from earth to the moon, then you reach moon gravitation field and up from earth will be down to the moon. Where is the neutral zone between the earth and the moon gravity and at that zone which directions your waste and blood are going to flow? At what locations that you will be in the sun gravitation field and escape from earth and other planets gravitation fields?
So what stops this pressurized suit expanding and going pop?
Andy compton it's fake
Instead of saying it's fake, how about doing some research. Space suits are made to be pressurized without expanding past a certain point. They use low pressure pure oxygen to allow them to breath and allow more flexibility.
Have you ever seen how thick the walls of a pressure chamber have to be in order to get a perfect vacuum? Yet NASA can do it with sewn fabric in 1969 ? Those suits would pop like a balloon.
But what protected them from solar radiation?
.......magic?
+FitnessNerd Nothing. It's not that dangerous.

+Arcadiy Ivanov Good read. Thank you.

+danglezbenderz not on the Moon or most of the way there
great
Hi!!! I'm so good at the moment and will not have the time of year
the thumbnail lol
Brought to you by Boeing. Enough said.
Exactly what psi does the suit need to step out into #space?
PS. I would take a dump behind one of those moon rocks.
3.7 psi of 100% oxygen.
you said the suits were pressurized to 100% oxygen to about 1/3 atmospheric pressure, are you sure? this seams odd, i'm not sure if we can breath 100% oxygen and also 100% o2 atmosphere is quite high fire hazzard and 1/3 of normal pressure?
+lordicemaniac You can breathe 100% oxygen. Also, 1/3 of normal pressure is about the same as at the top of Mt Everest, but since its 100% oxygen, it's still easy-ish to breathe.
Yes, she got it right.
It all starts, and it all ends, with a diaper.
Spacesuits keep ASTRONOTS safe because they never leave the EARTH simple
I tend to agree as the massive reduction in external pressure would result in some form of bloating as the human being inside the suit would create it's own expansion as there is no air-pressure to counter it. To contain the expansion pressure any suit would have to be extremely strong. Also suits would be totally useless against deep penetrating radiation from the Sun that requires several atmospheric layers to render it safe for humans to survive! Baffling!
frank barry hmmmm maybe the internet and technology that you typed this also is a product of your imagination
Stfu. This is a no idiot zone. Don't try and be clever and say I shouldn't be here either. You're just so desperate to be special that you go with rediculous conspiracy theories to stand out. Im also guessing you're a boomer?
Are you saying they don't leave earth as if there's no space? Because if you are your wrong
I can’t tell if he meant to say ASTRONOTS or he doesn’t know how to spell
No hate tho
you guy should do a video about if kraft dinner Is good for us or not
But what about the Spacesuit Satellite?
Amy ;)
i was thinking about the StarCraft Terran marine armor...
Like to vids of actually testing the bloody things!
Here’s a better question how can spacesuits withstand Micro meteorites and other space debris that is said to be traveling at a speed of 22000 mph or faster but yet it can’t withstand a bullet that is going 1700 mph
They can’t. If an astronaut gets hit, their dead. Space debris is very rare and unlikely to hit you.
Phew, almost thought it would be that freaky guy with his stupid glasses.
RevanAlaire and belives the moon landing was fake and earth is flat what a flatard!
What did she say?
I was just staring..........tongue hanging out, drooling......
+Mr. Johnson yeah, puberty is intense
she isn't Even good looking. I guess puberty hits hard on some people.
+CombatAngelGaming same dont know why people are drooling over her
How did they protect the astronauts from gamma rays and other deadly radiation on the moon?
yes, shit on yourself in space is one of the greatest archievement of mankind
Now how much do they cost
2:00 Those souls on the boots don't match the footprint on the moon Apollo 11 took a picture of.
+Crab Jockey Notice the outer boot layer to the right of the inner layer
i digress if humans die in the vacuum of space but we don't have artificial gravity yet how are they alive on the international Space Station
Umm there is air lol. The ISS acts as one really big space suit and the astronauts are inside of it. The air can't escape, so therefore there is pressure, but no gravity.
@steam-engines it's all totally made up BS! Filmed in a studio, they're attached to harnesses 🙄
I dreamt of being an astronaut, but then learned of the pooping difficulties in space... yeah, totally ruined it for me.
If earth didn't have a high pressure atmosphere we'd either not exist, or have evolved to be native to a low pressure atmosphere :P Either way, we wouldn't die.
It's not accurate to imply that the mechanical partial pressure suits were the direct precursors of the Mercury space suits. The Mercury suits did not use the same technique. Instead of squeezing to simulate the effect of pressure, the Mercury suits were actual pressure vessels, providing true, though low, atmospheric pressure inside.

Whether they went to the moon or not,being able to excrete waste while watching TV in an opaque suit is a lazy man's dream.

She recently quit but she still has her own channel
400 degree variance between light and shadow....guess that Apollo 11 rubber suit never melts in the sun or cracks in the cold!
This is misleading. It is true that the temperature variance on the moon is this large, but what continuously gets left out is that these are the extremes. It is always implied by the uneducated that this means that something that goes from the shade to the sunlight IMMEDIATELY jumps up 400 degrees. Also, there is no air on the moon - so there is no medium through which to transfer heat, so the temperatures that get quoted are the SURFACE temperatures on the moon. The lunar day is 29.5 Earth days long, so there are parts of the surface of the moon that are exposed to sunlight for a full two weeks. Astronauts on the moon were not exposed to the sun for anywhere near this long, and they purposely landed on an area of the moon where is was dawn. The sun was low on the horizon and the temperatures had not reached those extreme highs. And again - we are only talking about SURFACE temperatures here. An astronaut in a white suit at lunar dawn exposed for just a few hours at a time is not going to reach dangerous temperatures. The biggest concern for NASA was venting the heat of the astronauts' bodies out of the suit - which was a problem sufficiently solved.
the "landing sites" are the same places they have bounced signals off the moon since 1953...a total hoax....did not go there,,,,,still cannot go there!
John Rogan I don't know what you are implying.
If you mean the retro reflectors, then what you clearly don't understand is that while it is true that you can bounce rada off the moon and such and get a return signal, without the reflectors, it's unpredictable. You might get 3% of the signal back. You might get 20% of the signal back, etc. The reflectors are designed to reflect back to the source regardless of angle, so when the shoot lasers at the moon and get a return of 95% - 99% of the signal back, it's a completely different story.
That said, I do not believe the presence of these reflectors is in and of itself proof that man put the there. However, there is otherwise a mountain of evidence that they did. I'm sure you reject this, and that's fine. But, you have ZERO evidence backing up your side. Just baseless claims with no support. Good luck with that.
techno mumbo jumble....too bad they never went to the moon!
John Rogan Pretty typical argument. Over your head, so you just reject it. Absolutely predictable
Amys hair is on point 👌
The suits were removed from Public display after some one noticed the " Footprint " on the moon DID NOT match the " Footprint " on the suit that was on display.
No?
You can only have a vacuum in an enclosed environment.
Matthew Thompson Jr vacuum is a term for space dipshit 🙄🤣 not your Hoover.
define vacuum....
So basically a personal spacecraft?!
wow, Amy is getting more and more pretty...what happen?
Hi amy! 😊☺😀
AMYYYYYYWoop her Animal Super Squad *wink
Orange juice leaked out of a spacesuit and landed on the camera lens on the Apollo 16 mission. Yeah, right, these suits will keep astronots safe from the vacuum of space
Synthtrack we also cannot build a strong enough submarine to explore the depths of the sea yet we will be sending people to Mars??
Yes I know, what I was writing was meant ironic :) because people cannot go beyond low-Earth orbit. If a spacesuit leaks orange juice it can certainly never be used in a vacuum.
Synthtrack I know u were joking. well I know they have zero gravity Chambers here on Earth. That's a fact. That's where they shoot all their space videos. U know, a Hollywood basement.
@@synthtrack8445 why can’t people go past LEO?
Hi
Lol
space means amy. always.
SHE LOOKS LIKE 50 SHADES OF GREY Dakota Johnson
so Amy,laci and trace and all sourcefed and Julia get more likes and less dislikes interesting
I still have problem with the lack of pressure outside, it is the same as if we take a large balloon, if is empty is easy to manipulate and bend, but fill it with 2 atm pressure (to equate 1 atm at space) and you wont be able to bend it... so, how the astronauts can move them easily? Please share we me if you know of a site that explain this.
We have never been in space. Thats your answer.. idk if you have seen videos of tanks implosions but that's under 24 inHg and 14 psi baro and its done on metal tanks. How the heck does one survive with 14 psi of pressure in a total vacuum of roughly 29.999 inHg? I would really appreciate that answer and an example. Because for some reason we cant make a space suit for the 2024 moon landing now 😂 🤦🏻♂️ nasa can't figure it out. Hahahahha
@@jamesbond7380 Nasa lost the technology. They claim most was done by hand calculations. C'mon, how is that not believable?
Nasa quote: 'The calculations needed to be something the computers on board the Apollo capsule could tackle with their limited, 1960s-era computing power.'
'Any way you measure an aircraft’s position, it comes with a degree of uncertainty. That’s simply because no tool can measure something perfectly and there are a lot of factors influencing a plane in flight: wind speed, weather, pilot performance... So, neither aircraft tracking systems based on radar and GPS measurements nor sophisticated calculations of your plane’s expected flight path can pinpoint exact coordinates; they’re really saying your plane is located somewhere within a certain limited zone. The smaller that zone, the more confident you can be that your craft’s estimated position is as close to reality as possible.'
I also read somewhere else, that they thought they were going to have to adjust the flight path as some point, then didn't have to. So they nailed it without any feedback, completely unbelievable...
She didnt say that those suits cost around 150 millón dllrs
Adult diaper!!! 🤣🤣
And yes you can pee and poo 🤣 in them
Where did julia go D:
I still don't understand why the suit doesn't break due to the pressure differential?
What don't you understand? I'm serious. I'll try to explain if you really have a question
+Mark Holm Why does the pressure differential, 1 atmosphere inside vs 9.8x10^-10 atmosphere outside, not rip the suit apart?
+camfunme The tires on cars typically have twice that differential. Bicycle tires go from about 1 Atm to 10 Atm differential. Why don't they explode? The same reason as space suits: they are made of strong fabric. Space suits, though, do not have a 1 atmosphere differential. Usually they have about 4.5 psi, pure oxygen inside. They still have to resist that differential, but it is not even as much as a bicycle or car tire has to resist.
Research on experiments, that show how those suits actually work in a vacuum with a human being inside.
Let’s see, Gemini, Apollo, and STS are just some that do that.
@@jakemckee1923 I'm talking about a human in a vacuum chamber with a space suit on.
When you see Amy you know its going to be a Amazing episode :D
someone asked. if space is a vacume, then why are space suits pressurized. isn't that like blowing up a balloon in a vacume sucking on the balloon?
gagik pogosyan the Earth's "atmposphere" should be sucked out by the vacuum of "space" . That's how it works here. But I guess astrophysicists have an answer for that too. Otherwise they will be out of a job.
