The Sokol suit and the "seal that keeps you alive"

2012-12-14 - CSA Astronaut Chris Hadfield, while training in Star City Russia, gives us an introduction to the Sokol ("Falcon") suit. This pressurized outfit is worn inside the Soyuz spacecraft during travel to and from the International Space Station (ISS). Hadfield will be launching on board the Soyuz December 19, 2012 to become Canada's first Commander of the ISS.

That's a bit unexpected. The way you "seal" that suit, by implementing multiple folds that are literally tied off afterwords, is the exact same way they teach us to seal our waterproof bags in the US Army. Same fold pattern, same tie off. I always wondered "Just how effective can this really be at keeping water out?". Well, now I have a lot more faith in it, lol.

[@mindstormmaster]

SkylerKing Keeps air in, keeps water out.

[@Maverician]

+SkylerKing While I don't know the specifics, I would be very surprised if that seal isn't significantly better than the material around the seal (in your example, the bag itself).

[@KougaJ7]

In the army I suppose I could understand the use of this method of sealing, since we're not talking about air pressure but merely water. Also the fact that it needs to be able to be mass produced. For astronauts I would surely think that there would be a better and faster method for sealing the suit from external pressure, given the fact that there's only so few astronauts and they operate in possibly one of the most extreme environments. Maybe in the future?

[@amperzand9162]

Kouga forward looking designs have the astronaut climb in through the back of the suit, and then pull down the life support pack and seal it over the hole, essentially having a big, square, hard-rimmed door to seal with a gasket and fasteners

[@straightpipediesel]

@@KougaJ7 American suits use zippers for the pressure seal, even in the Mercury program. The seal you see here is what the Soviets designed in 1973 and it's never been changed.

Keep strong. Dont forget that despite the evil in this world, God is full of justice, mercy and love. Justice said we broke His perfect law - causing the world's previous perfection to be destroyed - and therefore we deserve Hell (like a punishment in any legal system but this is eternal as His perfect law is eternal too). Don't think you fit in that category? Ever done one of these?: lying, stealing - regardless of how small the object EVER, hating others - which is murder in God's perfect law, lusting (plus God sees our entire thought life). Justice says "the soul that sins shall die" - if we break one in thought/word/deed it's as if we're guilty of all of them. Quite simply, living by the law (which is doing everything perfectly) is impossible for sinful humans . The law shows us that 1. We will die in Hell if we fail to follow it and 2. We cannot save ourselves BUT, 3. God's perfect, immovable law points us to Christ, who followed and fulfilled the law in thought, word and deed perfectly in our place. He did what we couldn't and did it on our behalf. He was then sentenced to death on a cross, and took our personal punishment for our sin, paying our penalty (like paying our fine) completely FOR us, and has given us freedom. If we turn from the sins we have committed and repent (pursue the opposite direction of love through Christ) He will, overtime, recreate us back into that previously perfect image through The Holy Spirit which Jesus sends to all who accept Him as their personal Lord and Savior of their life. It's not about following the law - perfectly, as it's impossible - it's about letting Christ in to guide and teach you and obeying Him through His power (not ourselves as it's impossible without depending on His power and instruction). He is our substitute in His life, death and resurrection. He essentially rewrote history in our place so that, if you believe in Him, it will be as if you had never sinned if you accept Christ's death as our own in our place. He is in Heaven right now preparing a place for us so that He can take His faithful, believing children home with Him when He returns. He will ressurrect us from death when He returns, giving mercy to those who accept His love, instruction and teachings in their life, and give justice to those who refuse it. He doesn't want ANY of us to go to Hell and die for continuing in evil and rejecting His way to life, thats why He died FOR us. Hes giving EVERYONE a chance, He wants everyone to take the free gift of salvation from Hell. He wants us to be His and begin to follow His life of love and service through His power and abiding (staying) with Him. So long as we keep our hearts near to Christ through His strength, strive to follow His will of perfect love revealed in the Bible, and let Him lead in the midst of (very certain) pitfalls and struggles, we will, in time, win the ultimate victory over sin, pain and DEATH through Christ. Even if you are willing to be made willing, pray for Jesus to come in and He will do what we can't. Give us The Holy Spirit who will guide us in the right way. NOTE: You are NEVER too sinful or messed up that God cannot turn your life around through Jesus. EVER. Regardless of what you've done or what you're going through you CAN make it through Jesus. If you have any questions let me know Xx

[@Kamradec]

It is made so you can jump into this suit very fast in case of an emergency. Regular EVA suit requires at least half a hour and help of another man to put on properly.

[@MrBrennanMatt]

his face looks so skinny compared to when he's on the ISS

[@samlangston6742]

Yea he looks a lot more sickly. Space really affects the human body.

[@Anonymous-or4ru]

What you see here is what he usually looks like. In space your face fills out.

[@Anonymous-or4ru]

This was recorded before he went to the ISS

[@Astrocat-od5cy]

Because of gravity, the heart works harder to pump blood into your head. However, because he’s in microgravity, his face swells up, because it’s easier to pump the blood.

[@genericfakename8197]

The human circulatory system is optimized for life on earth, where extra pressure is needed to send blood to your head. In a weightless environment the circulatory system now sends too much blood to the upper body, causing swelling and "flu-like" symptoms such as a stuffy nose.

[@skipstah70]

remember, the air pressure is from the inside of the suit. Bound up right, that hole would be as strong or stronger than the seams in the rest of the suit.. certainly not a weak link.

[@PointyTailofSatan]

The US suits simply use O-ring based locking rings, like that used for something as simple as waterproof flashlights. Not particularly hard to make. I would think the Russian system depends on suit overpressure to ensure nothing enters the suit, and that a small amount of outbound leakage is probably expected.

[@Spitfire0818]

This was before he went up in to space... You always look younger when you return...

[@KDErkisi]

He looks older on earth because his bodily fluids are pulled down by gravity so his face has less liquids in it, making it look more gaunt and pale. In space, the bodily fluids are distributed evenly through his body so he has a pinker, juicier face in zero-gravity. That's my theory anyways.

[@TheMinecraftinvader]

in space low gravity causes liquids to rush to the head and makes your head swell causing less ''wrinkles'' , also just body lines or wrinkles would virtually disappear because in space gravity does not affect your spine so it makes you taller :D

[@bob46802]

This is correct. Your heart no longer has to fight gravity to pump blood into your head and brain, which cause massive headaches. Your spine is also no longer compressed by gravity so you can get pretty bad back pains too. I think the record for growth in space from your spine stretching out was about 2 inches.

[@madcowzrchewy]

Because this is after he's gotten back to earth, which is more recent. The lighting is also different, which makes his hair look less grey

[@billsixx]

That's how the original drysuits worked for diving in the 50's. BTW what is the giant blue puck on the chest for? Could they make it a little bigger?

[@bergonius]

Lower tech level - less things to break, less possibility to break, and easier to repair if it's happens. I wouldn't fold my life to mass of hi-tech electronics where i need just protection from low pressure. Simpler thing - less likely it will set me up some point.

[@TheEbber22]

So this is as simple as screwing on a bottle cap, and making sure it doesn't screw of on it's own.

[@Loweene_Ancalimon]

Kinda. It is very simple, but it works. That's how water-proof bags are sealed, too.

[@richie0099]

A lot of thinking goes on space suits and the security of astronaouts a lot of trial an error must be done a really working suit on for any emergency. Picture this, a ziplock is made of plastic, what if there's a lot of heat in the capsule and the plastic melts, that cord may be able to withstand more heat than plastic and it is easier to manipulate. Fancy is not allways functional in some scenarios.

[@lechbutt]

This is my favorite spacesuit ever , I hope the creator of Roblox space sailors add this

[@PointyTailofSatan]

There are still O-ring type seals for the gloves and helmet.

[@martinc.720]

PointyTailofSatan isn’t an O ring what lost Challenger?

[@Ravaxr]

Yes. But that was because the ring was too cold for the violence of a launch and was used outside of the engineering specs. These suits aren't meant to be used outside the space station or capsule, so they stay relatively warm and pliable, and aren't being vibrated like the Challenger booster.

[@whopperlover1772]

Imagine being excited and ready to see your mates in the capsule only to see them dead and not know to react around everyone else waiting to see them carried out, sad stuff.

[@cyberk25]

just sayin I'd be pretty nervous if i had to fold my own life saving air seal haha

[@AntiMeridian95]

he mentioned it in another video i think, its the gravity back on earth that makes everything sag down a little

[@LeonardoValle]

It was introduced in 1973. No astronaut has been killed in the Russian space program since then.

[@slapnthface]

one of the other austronaut said that in space you dont get wrinkled skin as there is no gravity to pull your skin down

[@09nkd]

because of gravity he doesnt have as much blood in his face so its thinner and paler so as a direct result he looks olders

[@nzoomed]

Im amazed how tying that could even work! looks so primitive, even the US had more advanced suits back in the Gemini days!

[@dBolotok]

Whatever works.

[@conorcorrigan765]

***** Like that old story about how NASA spent millions developing a pen that would write in space, and the Russians just used pencils hehe...

[@mibars]

If something is stupid, but works... Then it's not stupid :)

[@HipposHateWater]

Conor Corrigan Except /both/ sides originally used pencils. What that anecdote conveniently leaves out is that Russia also switched to pressurized pens after the Americans did, since graphite dust kept screwing with various filters in their life-support.

[@InquisitorBill]

The point is is that while the Zvesda or the US suits take up to half an hour to get on, the Sokol can be jumped into quickly without much assistance; which in an emergency is the point

[@rediskewl1]

That's wonderful but you don't understand what Isaiah was speaking about. He only meant that Chris appeared older than he does in all his life in space videos. At the time of this video Chris was not in space and had not been in space since STS-100 in 2001.

[@supavikishgirl]

[@goaliedude32]

The gravity acting on them is almost exactly the same as that here on earth!

[@LordLares7]

He doesnt look older, u can say that on ISS he looks younger. And thats becouse there is no gravity and the fluids are not pushed down therefore his face is all swollen.

[@krinord]

If you've seen the newer videos of him he looks younger

[@temper44]

It seems the Russian philosophy is to keep everything as basic as possible, that way there are very few things that can go wrong.

[@pinkshrimp]

I meant more like an actual vacuum seal and not a plastic bag, I would be afraid that air would escape through the folds. This still doesn't explain how that method works, I was just curious, not doubting NASA...

[@knifetoucher]

Wow, that suit looks so low-tech tying that hole up with a string.

[@VILLAINOFYOURDREAMS]

IT'S SIR HADFIELD :D HE'S MY HERO!

[@ElGringoft96]

When astronauts get to space, their heads swallow because there is no gravity pulling the blood to their feet. Because of that, the skin stretches, and some of the wrinkles disappear. That's why he looks younger in space. But that's just my theory ;)

[@psycleen]

[@IndyTheGreat]

[@pinkshrimp]

I'm pretty mystified here, it isn't a seal so much as a tiny cord holding it together. How does that work efficiently? Wouldn't it be safer to have a sort of ziplock?

[@creamylord]

Probably because of gravity pulling down on the skin/muscles of the face. Whereas zero gravity would act like a sort of face lift.

Astronaut Chris Hadfield seems to move around easily in this suit but it seems so bulky that it looks to me like it would be difficult to move around in. I wonder if zero gravity makes it a lot easier to move around in a bulky suit? I would imagine so since you weigh much less in zero gravity.

[@travismoss3492]

It isnt really that easy to move around in. Most of the time it is pressurized, they are sitting in the Soyuz. once they confirm it has no leaks they depressurize the suit and its like wearing a big rain coat.

Keep strong. Dont forget that despite the evil in this world, God is full of justice, mercy and love.

Don't think you fit in that category? Ever done one of these?: lying, stealing - regardless of how small the object EVER, hating others - which is murder in God's perfect law, lusting (plus God sees our entire thought life). Justice says "the soul that sins shall die" - if we break one in thought/word/deed it's as if we're guilty of all of them. Quite simply, living by the law (which is doing everything perfectly) is impossible for sinful humans. How does this get fixed? Well, mercy said "I dont want to give them what they deserve. I don't want them to be cut off from Me. I love them despite all they have done/will do against Me. I want to give My children another chance. I want them to come home and live in My love again". But the evil had to still be dealt with, as God - being good - cannot simply let evil off scott-free. Like a judge can't let a murderer off scott-free, otherwise it shows approval of it. And so, love said "Jesus, God's Son, came down as a Man, our representative, suffering every temptation, pain and struggle we have ever faced, yet without sin. Living perfectly ON OUR BEHALF. He took all our sins (past/present/even future) to the cross and then crucified EVERY ONE on our behalf, like paying the fine to legally free us. Justice was paid on the cross so that we can be free from Hell's punishment, experience Gods mercy of forgiveness of sin and live in His love. If we turn from the sins we have committed and repent (turn away from our sin and pursue the opposite direction of love through Christ) He will, overtime, recreate us back into that previously perfect image through The Holy Spirit which Jesus sends to all who accept Him as their personal Lord and Savior of their life.

So the seal the large opening in the suit is just bound tight? Why is that? Surely there would more secure ways to keep it closed.

[@Stepclimb]

Chris is wrong about blood boiling if the vehicle lost pressurization. Blood is contained in a closed system and is under pressure, so it would not boil. Moisture in the nose and in the mouth would boil above the Armstrong line, but not blood. Consciousness would be lost in about 15 seconds, followed by cardiac arrest as blood PO2 fell.

[@venbrou]

Technically speaking, time travels slower while in orbit. So much so that the clocks on satellites have to run slightly faster to stay synced with ones on the ground. So in a way, Nasa and everyone else who has ever launched something into space has inadvertently made a time machine. This is Einstein's theory of relativity in a nutshell: The faster something goes, the slower time is for it, and things in orbit travel faster than you could possibly imagine.
