How Do Spacesuits Keep Astronauts Safe From the Vacuum of Space?

There were many iterations of the spacesuit before astronauts started wearing what they do today, but how do they work?

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 https://airandspace.si.edu/exhibitions/space-race/online/sec300/sec370.htm “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.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

How on earth can it protect them in a vacuum...
-
So what stops this pressurized suit expanding and going pop?

Evilpreacher evil funny

You can pee and poo in me, sweetheart. (;

TAKE A SHIT IN SPACE!

The Achilles Heel of the NASA space program hoax is the spacesuit with ice sublimator cooling system because it can be verified on Earth today by demonstrating a spacesuit with ice sublimator before independent witnesses operating in a high vacuum chamber on Earth duplicating environmental conditions of orbit.
Unfortunately, in their over 50 years of alleged use, NASA continues to refuse to scientifically verify that spacesuits work as claimed.
The NASA space program is a faith-based thing and that's unacceptable. -
400 degree variance between light and shadow....guess that Apollo 11 rubber suit never melts in the sun or cracks in the cold!
-
nasaistic FILTH. copernican SCUM. astro-NOT!!! masonic satanists.nasa-dualic truth.
Nasa-Never A Straight Answer. KIll Kill Nasa-NOW!!! -
lemme slide this dick in your ass and make you poo girl
-
you can also fall all over the ground on your chest and bounce up and down on your chest with all the equipment and everything else it doesn't damage the camera mounted on your chest it doesn't heard a thing if I was on the moon and the only thing keeping me alive was the suit that I had on I don't think I would let myself fall on my chest and if I did I wouldn't walk around like a stuck pig I would be calling for someone to help me so I didn't have to bounce all over the millions of dollars of equipment on my chest watch films of the moonwalk

why do people think the earth is flat?
-
Na
-
anyone knows what happened to julia?
-
talking shit love !! space shit that is
-
Most interesting suit ever flown? Went to the mile high club so the bottom half of my birthday suit
-
yes, shit on yourself in space is one of the greatest archievement of mankind
-
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.
-
fuck this bullshit hiding the bigger question in plain sight wtf keeps earth safe from the vacuum of space !?? my vacuum needs 10mm thick plexxy glass walls ...
-
are they really planning to send people to mars? when is it going down? or up ;)

Just wanted to go over something here. If you pressurize your suit to 1/3 atm that would be around 4.6 psi. Which would be the equivalent of around 26,000 ft. You would be the equivalent of a Mt Everest Mt. Climber. In other references I have seen it at a rediculous low value as 3 psi. In both cases, even with an oxygen rich environment you will still become fatigued quickly, you will get the same serious problems as a Mt. climber. Such as AMS, you can get an embolism and you will have eye problems same as a Mt. climber Even in an oxygen rich environment. Because your body is depressurized. What most people don't know is that the ISS (and a capsule) is supposedly pressurized to nearly 1 atm. That means if you attempt to suddenly go from 1 atm to 1/3 atm you will certainly hurt yourself. Even a Mt. Climber stays at base camps at various to acclimate. And if you go from 1/3 atm to 1 atm you will get the bends. So you would have to just slowly turn up or down the pressure going in and down the suit for at least an hour. You will kill yourself if you did either instantly. How would you like to get the bends in outerspace?
Second, you are in a vacuum, which means thermally it is the equivalent to being inside a thermos bottle. It will accumulate heat and the heat will have nowhere to go. Half your body will be cooked to 250+ and the other half WILL NOT FREEZE (this is a myth) as there is nothing to convect out the heat. There is no known way to remove heat via convection in a pure vacuum, other than water sublimation which is impractical as you have to waste water into space to do it. Last time I checked I dont remember seeing any water tanks hanging off either the gemini or ISS, nor any spray jets. And all methods require huge amount of energy to do it. You CANNOT just route water tubes around your body, nor can your rely on a some magic AC unit in the capsule. Since both you and the capsule has same problem. Which is you have a heat source (the sun) cooking you almost immediately and no way to remove the heat.
Third, your suit even at 4.6 psi would balloon you out like a stay puff marshmellow man. If you think you can solve it with a material that does not balloon out. Then you have the next impossible problem which is you would not be able to move, you may think all you have to do is have articulated jointed gloves, but that still wont help you. Not to mention your knees and elbows. If you have somehow think your going to fight against all this pressure you will become fatigued quickly fighting against your suits pressure even if it it's small.
