The fact that the scientist was unsure that Italy used HIS design until Destin brought it to his attention, and the reaction he had.. brought a tear to my eye.. so beautiful!
@@mikefriedman5635 i think your brain is "fried" man. Get yourself a NikonP900 and capture the ISS yourself on a photo. Idk what you consume but please, for your own health, consume less.
Dan Smoke Best thing about being an astronaut on the international space station? Not having to deal with angry sound guys yelling at you for dropping expensive and sensitive mics that need to be sent off for expensive check-ups when you drop them on the ground... because when the mic falls it just falls in sync with the rest of the space station as it orbits the Earth.
She did the outro from space. She... she told us about her country's contribution just to explain a shutter... from space. I got chills, and tears. Holy junk that was awesome.
“I hope it’s flawless”. Despite to part is working for over more then 2 decades (?) an engineer will still have his doubts. Could i have made it better? Could i have made it more durable? Could i, could i.... Love it!
I would've liked to have seen more of that engineers recation to you telling him that his design is actually the on being used. He seemed stunned about it.
So much warmth in these videos. If that makes any sense. The cordial interaction between men and women of science for the purpose of education, Destin's playful yet respectful style of interviewing, the family stuff in the background, it radiates positivity and hopefulness for the future. You don't get that in many other channels.
Being 3959 miles away from the center of the earth and we get 1g, being 4211 miles away and gravity disappears..... incredible! That gravity sure is ggggreat!
@@bgilchrist228 the earth's gravitational field does not come from the centre of the earth though. It comes from all of the earth's mass. The ISS in fact does experience most of earth's gravity but they are weightless because they are in free fall. Reading "The Ascent of Gravity" at the mo so proper boned up on gravity facts lol. It's a good book so far.
@@SpeakerMunkey They are in free fall? LOL. How are they in free fall when they are traveling perpendicular to the surface of the earth at a constant speed? Please cite any experiment where weightlessness is achieved without acceleration.
He’s interviewing the same guy that said “we lost all the technology that we used to get to the moon and that’s why we’ve never been back because, it’s just to difficult to reproduce.”
something about him is extremely off, I highly doubt he is of any use for NASA, could not see him logically doing anything intelligent, I think he just has some psychological things at play such as lying continuously with no moral effect that NASA likes in all employees.
@@zpirateko2129 no he was referring to apollo moon missions. They 'lost' all papers, text, documents, and data on how to go to the moon. We dont know how, we just know they 'lost' it

M. B alright buddy, astronauts have and nasa have spent billions creating a lie to manipulate human kind into thinking the Earth is flat... riiight, you don’t even believe that yourself
Justin Baker funny that was the same exact thought I had, hearing a man like him say that felt like being obsolved of some kind of sin, don't feel guilty about having said that in the past after rigging some kinda something!
They are just rubber rings. If yours are continually failing then they are inappropriate for the job. Buy better quality and they won't fail all the time. Simples.
@Martin G Yeah, like they are not shielded by the metal around them. on the inside there's a shaft, on the outside a groove, there is no way they will bne damaged by radiation. O-rings and other rubber seals are used in countless aplications and when used properly they will last for a very long time. Take the seals in a car gearbox, often they are below the oil level, and yet a leak between the gearbox and the driveshaft is almost unheard of. Those flimsy rings have been sealing stuff for decenia and they work fine.
@Martin G How much radiation do you think is up there? As has been demonstrated recently a small air leak isn't a big deal on the ISS, and it certainly isn't "life threatening" unless it's completely ignored. Rubber is used to seal air gaps everywhere, not just on the ISS.
The dude at the end, kinda not daring to ask the question "So, are you sure they are still using that same design? They kinda never got back to me" You could see the stars in his eyes :)

This is one of the coolest videos I've ever seen, mostly because it is so well put together! Most people would stop at talking to astronauts, but you took it one step further and talked to the actual engineer who designed it! I applaud you! Subscribed and liked!
"You can tell it's real Because it looks so fake!" Haven't Checked This In A Long Time Had No Idea It Was On Fire, Appreciate Those Who understand And Came To Defend The Truth...
Destin SED While still sitting behind my desk in my office with an indescribable suppressed excitement over what I just saw, I have to say, "cool" is an Out-of-Earth-Understatement! Great Work!
Ian Maitner well they had a leak a while back I think the immediate solution was put duct tape over the hole 1 atm pressure difference isn’t that big, so a tiny hole wouldn’t be a major issue
+Juil Destin +SmarterEveryDay you put that man's mind back in space, even if only for a moment, that kid in him sprung alive and he was like, "My design is in use in space! Cool!" You are so awesome.
I literally got tears in my eyes, when the astronaut said your tagline for you. I've come to love your videos, and how you are so interestingly passionate about everything around you. People like you make me proud to be a human being. Thank you Destin.
an o-ring between you and the endless void of space certainly sounds much more impressive, but the seals in the gas springs of an office chair or a cars trunk door have to withstand much higher pressure differences, not to mention the hundreds of bars in hydraulic cylinders.
+Cuda FX = Yeah, that's true. Have you noticed that after 6 years, those struts won't hold up your car's hood or trunk anymore? All the internal pressure is GONE. That's when you bring out the modified cut-down broom-handle to hold them up.
+Cuda FX indeed, I don't know the actual atmospheric pressure inside the ISS, but assuming it's 1atm, they have to withstand "only" 1kg/cm^2 of pressure. That's not a lot
it's the same pressure as on earth at sea level, i just looked it up. it surprised me a bit, though, you could propably get away with running a spacecraft at just 70% or so of that (the pressure you have on a 3000m mountain) and save conciderably in weight. it feels so counter inhtuitive, that submarinest have to me much stronger than an actual spaceship.
Cuda FX I've looked it up, and found this interesting post space.stackexchange.com/questions/5690/why-is-the-breathing-atmosphere-of-the-iss-a-standard-atmosphere-at-1-atm-conta You should check it out
+oromisszane Well.. even if he left the project years ago and the italians finished the cupola.. even they still knew it was him who did it.. rather than take credit themselfs... this show how this comunity respects each other greatly even contributors that left decades ago (the freedom space station was changed into the current ISS project in 1993
5:41 Where he asks if they did follow up on his design. They did, it was such a great design! Very sad how the engineers and scientists that come up with these things never get the proper recognition, hats off to him for creating a life-saving feature and being so humble about it. You sir are a legend and will always remain a hero!
But here's the thing , when an engineer designs something for someone and they put it together ,the engineer usually has to certify their work to make sure it's all correct and they haven't cut corners or whatever, so i find it odd he didn't know they used his design. I know this because we have engineers come to my work all the time to check up on things.
Destin: "Well, what happens if you have a leak?" Don: (huge gulp) "uh uh uh, well, I guess you have a leak!" (Then smiles as if that was a good response) Me: 😂😂😂😂🤣🤣🤣🤣🤣🤣🤣
@@ianmcian2954 Getting tired of you. You obviously have NO idea what negative 6 to 10 tor means. Again, the aspersion you sling suits you SO PERFECTLY! It's not about the 1 atmosphere, it's about the ratio of DIFFERENCE of pressures between the inside and outside. Stop denigrating people when it is YOU who knows stuff all about what you nastily espouse. Just one more thing Ian. Read the comments. Notice how the majority of people smell something fishy, because it is, and all you are is adherent and nasty. Talking about wasting precious oxygen.. you know about that.
@@ianmcian2954 The blinkered view of reality you have is a sad symptom of the lies you were fed. I don't blame you for thinking Neil went to the moon.. But I do despise you for your vacuousness and rudeness.
I work with Isolation tools in the oilfield, I "sting" large diameter pipes into a pressurized well 5-15,000psi using hydraulic rams, and the only thing that keeps the pressure from being released to the atmosphere is an o-ring with .127" thickness.
I don't think you grasp the difference between vacuum and normal air pressure, and higly pressurized pipes of oil? You're lauching into space a lightweight structure not an oilrig.
Jack theres a difference between fluid dynamics and aerodynamics. First being the molecular structure size. Pneumatic cylinders cannot handle 5000psi utilizing the same o ring. Also, if air can pass through the rubber in your tire, it can pass through the rubber o ring in space. Thats why nitrogen is used in car tires more commonly today. I used to repair hydraulic aircraft jacks for Boeing with up to 100 ton capacities. Certification was required annually on all jacks and overhauling was done in 3-5 years depending on service. How many years have these o rings been in service?
@@Illusion-clock LOL! There is NO DIFFERENCE , as far as the o-ring is concerned, if the differential pressure on either side of it is a higher positive pressure on one side and atmospheric pressure on the other side of it's seal as opposed to atmospheric pressure on one side (or even a pressurized cabin for example) and a "vacuum" on the other side. A vacuum is just a lower pressure in reference to atmospheric. But it is not a negative in absolute pressure. I am assuming you are a flat earther or something? HA HA BTW, I use O-rings to seal between atmospheric pressure and vacuums, a DEEP vacuum at that, almost every day.
@@PsalmFourteenOne deep vac eh! 10E-17? Exposed to delta 500 degrees at any instance? Are your O rings factual? Or does Daddy work for NASA fraud? I'd rather have JESUS and LOVE then liars and hate!
The reason why he brushes it off, is that a small leak in the ISS would not be very dangerous. (I’m talking leaks that are less than 2 inches) because inside the ISS is an atmosphere of 1 atm (14 psi) so a leak of 1 inch will only have a pound force of 14. (Considering the pressure differential is 1 atm - 0 atm because space is a vacuum) So you would be able to deal with that temporarily pretty easily. Thinking that it is a huge deal is like thinking that because you filled a tire to 30 psi it is going to explode if it gets a hole in it, when in reality it will just give a small hiss while air escapes until the pressure differential between ambient air and the tire is 0. So a small leak on the ISS could be brushed off. The only difference is that instead of changing your tire and putting a new one on, you have to fix your tire while on the road.
I thought this video was about 7 holes made by small rocks in the ISS, I was like, "nice that is interesting, let's click". Then you talked about something 1000x more interesting so yeah, awesome video !
I thought your comment was gonna describe a clickbait and I liked it before reaching the end, then I saw your hyperbolic praise of the video then I disliked.
+briansmobile1 Gotta love that Six degrees of separation. Love your video's as well Brian. Really cool to find people you know of in places you didn't expect them to be.
So fascinating... You didn't talk about how the O-rings are lubricated, since it must be a pretty special lubricant not to freeze up or boil off in the kind of conditions there must be up there?
@@paulg4815 Lol yea, I saw the footage live from the car being sent into space. They edited it later, but that live footage showed the real surroundings of the car in some studio.
I'm not arguing for or against. ...but, funny you have no idea; you're unsure what would even happen...freeze or boil. If it's a lubricant that's avoiding its boiling temperature; seems very do-able
So, let’s be clear. Two tiny “O” rings stand between safe operation and catastrophic explosive decompression. Two tiny “O” rings. It even allows for the shaft to be able to turn so as to initiate the raising or lowering of the covers. Just that fact alone tells you that it can’t be airtight. And there’s one word that is not mentioned in any of this: VACUUM. If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately. You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber. As Pettit(?) claims, if a leak occurred, there would be a drop in pressure and there would probably be a plan- which he didn’t know- which would be implemented and would probably require a spacewalk to fix. Sorry folks, but if a leak occurred everything and everyone would cease to exist in the blink of an eye. 😂😂😂😂😂
"If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately." -Wrong. "You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber. " - Wrong. "if a leak occurred everything and everyone would cease to exist in the blink of an eye." - And wrong again. Why do people who clearly don't know what they are talking about bother commenting?
@@CSXRobert Yes Robert, why do you bother commenting when you don’t know what you are talking about ! When you have more than 40 years experience working with pressure differentials, aerospace materials science, vacuums and seals- metals and synthetics -, like I have, then hit me up ! In the interim, thanks for the laughs ! 😂😂
@@stephendaskey5128 Well, since you seem convinced you are right, I'll explain how you are wrong: "If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately." - The internal pressure of the ISS is standard atmospheric pressure - 14.7 psi. Since the pressure around the ISS is very near 0 psi, the pressure differential is 14.7 psi. O-rings can withstand pressure differentials of several hundred psi. "You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber." - If you use the wrong rubber then yes, it will outgas and fail. There are many different formulations of rubber and methods of making and treating it. Some of them do have major outgassing issues in a vacuum, but some do not, such as the high-vacuum fluoroelastomer O-Rings that anybody can order from McMaster-Carr. Naturally, NASA chose an O-ring material that can withstand high vacuums. "if a leak occurred everything and everyone would cease to exist in the blink of an eye." - Exactly how would "everything cease to exist in the blink of an eye"? As mentioned in the video, it would be a leak. You ever have a leak in a tire, or inflatable pool float? I have, and it's never caused a "catastrophic explosive decompression" and there's no reason it would on the ISS. If the O-ring suddenly completely disintegrated, it would likely leave a gap with an area less than a 1/2 inch hole. The ISS has a pressurized volume of over 32,000 cubic feet, it would take quite a while for enough air to escape out of a half inch hole before it became a problem, plenty of time to seal off the cupola. Add to that the fact that a failed O-ring would not suddenly completely disintegrated, but would actually develop an even smaller leak. Of course, someone with "40 years experience..." should know all of that.
O-rings that move about are really not a big deal. For example, any SCUBA regulator will have at least one O-ring that has 200 bars (3000 psi) on one side and 10 bars (150 psi) on the other, with a movable tube in the middle that, when in use, will move hundreds of times per minute. That thing will last for years without having to be replaced. Compare this to the space station, which has 1 bar (15 psi) on one side and 0 bar on the other, and whose shaft moves what? 4-5 times per day? Sounds like a vacation compared to a SCUBA regulator...
as i commented earlier, when you put space superstitions aside you realize that it is not as extreme as you think. the difference between in and out of the space station is really only 1 atm (15 psi). So the nearly 3000psi difference mentioned above is imo more impressive.
I have always found it odd that the general public is "scared" by the media about space being airless and how dangerous a hard vacuum is but they seldom mention the really scary things about space. Radiation ubiquitous and *LOTS* of it and dynamic temperature differentials that occur often and repeatedly. Hundreds of degrees in the span of an hour. Velocity differentials of many thousands of miles per hour between so many whizzing objects seen and unseen. 60 miles up you only have a 1 atm pressure change which is the same as a depth of 32 feet under water. Scary pressure changes are what submarines are all about. Outer space is a challenging environment but not usually in the way most folks seem to perceive it.
She had to, there is nothing to keep the Space Station from spinning, if you accelerate the cover quickly, then you could cause unwanted oscillations in the Space Station, like wobbling solar panels, which as you can guess isn't good.
CockatooDude Whoa... I guess that's a possibility--but considering that there is no air to fight against such a movement or anything really, why would doing it more slowly help at all, in terms of not applying any centripetal force? Well wait, nvm I think you are right. If it bangs on the window hard, that could easily create more movement than a slower, more controlled motion. Touche.
As an aerospace engineering student, the gradual move from mechanical to electronic systems has always made me slightly uncomfortable. Call me an old fashioned sod, but I've always believed that simple mechanical systems are always more reliable than electronic ones It's great to see that there are still places where mechanical over electronic systems are being used for their reliability ^^
Vectored Thrust You wouldn't like all our new aircraft then, all "Fly by wire" these days and it turns out atm they're much more reliable than the old mechanical ones. I'd rather a cable with a bundle of wires and multiple backup systems over a metal cable that can fatigue, break, corrode, kink, etc. Improper maintenance of a Pulley cable compared to a wire bundle, well, the wire bundle will go much longer than a Pulley without any maintenance.
Vectored Thrust Newer electronic systems are far more reliable than older mechanical systems. More back ups, quicker responses, less maintenance, smaller components...its why engineers have changed a lot of mechanical systems, be it cars, aircraft, engines of all sorts, to electronic systems.
Vectored Thrust I'm an old fashioned sod too. and proud of it. the more automatic and computerized things get the farther they seem to be removed from reliability.
I would've never have thought that there were direct mechanical connections to the outside of the space station, not to mention the fact that the vacuum of space is being sealed off by 2 tiny o rings . Thanks for enlightening me today Destin.
The astronaut doesn’t know the protocol for a leak in a space craft in a vacuum of space? This is very hard to believe they were not endlessly trained in protocols and lends to his credibility. I think they are all under some hypnosis. They really don’t have the appreciation for the fact that if they have cataclysmic pressure loss their bodies would be sprayed across the universe in less than a second. Has anyone seen the door that closes this compartment off? This space station must withstand more pressure than a submarine, should be build more solid than a submarine, but made of aluminum? Some of this is just ridiculous. Do they have unlimited supply of air too? How many times to they get deliveries? Air and water? When I go camping we can’t last more than a week and that is pushing it.
To start don Pettit hasn’t flown is space since 2012 so he prob forgot certain protocols. Second submarines have to withstand up to 30 atmospheres at 300m, space stations only have to withstand one. Like on submarines they use electrolysis to generate oxygen from splitting water into hydrogen and oxygen. Usually they get resupplied every 2-3 months. And when the send supplies there they pack it with stuff to last for 3 months
@@pukas7389 you mean the space station that there is no video diary of being constructed? That ISS that magically appeared in the sky with no fanfare, and no actual footage of how they made it
I almost teared up when the engineer came to the realization that his 20 year old design was in use on the space station. I can't imagine how rewarding that must feel.
+Kakarot7 From my understanding, those are two very different forms of heat transfer. Radiation is the transfer of energy that can occur in a vacuum, and without the atmosphere to shield astronauts and spacecraft it is being constantly pelted with solar radiation. Not having enough particles in space to transfer heat is okay because energy and heat are not being transfered through convection.
Karl Tablay Yah, if an object gains energy or heat in a vacuum without physically touching anything then that would be energy transfer through radiation. That's why they put gold foil because that would reflect the majority of the radiation so it wouldn't damage the scientific instruments,
Thankfully they are less than 0.0001% of people. People just love bringing it up for some reason and pretend like they are an actually significant amount.
I realize how amazing the main topic of this video is; However the greatest point of enjoyment for me started at 5:42, where you see an engineer starting to realize for the first-time that a design he created was currently being used on The ISS. It appears to me that he is holding back his excitement while the conversation is taking place and the event is being recorded. Those moments where you get to see other people experiencing joy always seems to overshadow just about everything else. It's always a pleasure to get "SmarterEveryDay", especially when the process brings such joy to others. -I'm not sure if I re-watched this video after so long to reacquaint myself with the information, or if subconsciously I wanted to watch that moment again.
I saw him cringing in hope he wasn't exposed, along with all of NASA. He had the face of a guilty man who had been caught, face to face with the Sheriff. Looked like he was ready and willing to spill the beans, rather than deny. A peaceful surrender. Then he realized this kid, and many other people, still believe the hoax! LOL!
so much anti-logic cramed into three lines - why would someone who once had dealings with NASA that ended years ago care about them being 'exposed'? why would this 'hoax' dedicated channel show it if that was the case? nothing about the system he made doesn't make scene in space so why would he consider it being 'exposed'? how would spilling about an 'conspiracy' be more peaceful then just excepting the existance of a think the people he is talking to have first hand experience of? etc. and who's a 'kid'?
What's his name? Justin? Dustin? Destiny? D-dustyn? Whatever his name may be, he has a really nice, friendly and warm personality. No wonder your channel is so successful. Keep up the great work!
It's amazing what we have achieved in such a small amount of time that we have been "advanced" enough to develop and engineer intricate pieces of machinery. I can't wait for the future.

"Dear Lord, that's over 150 atmospheres of pressure" "How many atmospheres can this ship withstand professor?" "Well it's a spaceship, so I'd say anywhere between zero and one." futurama xD
actually, (bad science incoming) I think the station is pressurized lower than standard atmosphere. it's 14.7 PSI at sea level. I think it's reduced to lower the risk of a leak or blowout.
Always is, find her hair and nails in space vid. One of far towels is solid and bouces, the other swings like in gravity. There's water going up and down both defying and obeying gravity!
Two moments I shed some tears in this episode. When you told Charlie that his shutter was built into the space station by Italy, and when Astronaut Critoferetti did your outro.
Man that Pettit is one mean photog. I see they finally upgraded your camera to one with a higher shutter speed Pettit. You've finally captured the ball Earth with those elusive stars in the background. How you managed to capture such breathtaking imagery while shooting through space at 1.4 million mph plus going in 3 other directions at a different speed for each of those directions is absolutely amazing. You, sir, have one steady hand. For the next set of amazing cgi magic pics, throw some Crayola Crayons into the mix. Maybe a color by numbers Supernova in the distance.
It's fascinating to see the shutter mechanism work so smoothly because of microgravity. I though there would be like a gear reduction like you'd see on shutters on earth but not so. Super cool!
That's the reward for working for NASA. Keep your mouth shut and be rewarded. Guess he might not even know about it, but guessing with his knowledge he must. Probably a freemason like the astronauts.

as an Engineer myself I couldn't help but notice those drawings were imperial, but virtually every country except America uses the metric system, seems like a recipe for confusion.
Yeah, there was some aircraft worth hundreds of millions which got broken cause one of the idiots used imperial system and noone checked it. :D But using imperial units simply doesn't work. It doesn't. You say you are engineer? Convert one liter to one cubic decimeter. It's 1:1. Now convert 1 gallon to 1 sqaure feet. Some online coversion tools says it's 0.2614. But when you convert 0.2614 sqaure feets back to gallons, you don't get one gallon, you get 0,9997 of gallon. Which would be HUGE miscalculation in something like spacecraft. Imperial units are remains of the medieval ages. Absolutely unusable in the modern days, completely unreliable for engineers. It was made to measure how big is your field and how much crop you grew. Not for advanced mathematics and unit conversions... Not for space travel. :D So, yeah, since America DID manage to get a shuttle out of the atmosphere, it means they were not using imperial units.
An astronaut using the words "probably" when talking about having a leak in the cupola? Really? One would think that there would be clarity as to what to do if there was leak while in space
The standard procedure would be to simply lock off the section that has the leak. Afterwards they either go fix it or they evacuate the station, depending on the damage.
Milkmaid, perhaps you could link to evidence that these "locking" sections actually exist and can perform the function attributed to them? Link to ISS leak protocols.It's all public domain. I'm here to help you "prove" space travel is real. :)
We know with certainty what happens with a leak in steam engine (for example), because we've seen it many thousands of Times, its well understood. We have a fair idea how it works under vacuum, but we dont have the reams of data. A good engineer is a cynic. It will probably work, but I dont *know*. You would be amazed how often "should" ends up "not". Always more variables out there to catch you. Dont trust a confident engineer. Only salesmen n marketing are confident, and they LIE.
He was referring directly the the procedure for replacing the cupola window mechanism, not what to do when detecting a leak. And as demonstrated this week a small leak in the ISS is not the huge deal people seem to want it to be.
What I love most about this video is that it showcases the vast potential of international cooperation. Less than a century ago, Italy and the USA were embroiled in one of the worst wars in human history. Today, they are building structures that reach into the heavens.
so technology means budget? No, we haven't lost the technology, we lost the money no money, no space that's simple and if you want another reason we haven't tried more than 15 times in the Apolo program is because of the solar wind, at the time we were ignorant and REALLY lucky than the sun was calm every time we went to the moon, but after we discovered than solar wind was a thing and a really dangerous one (can easily roast a man in its way to the moon or on the moon)

At 6:00 in, I noticed marks on the window behind Samantha. Are those marks from miniature meteorites, stars in space or just a reflection from inside the module?
Dan Hunter Generally, none of the windows on the ISS are going to be spotless. There are always bombardments from tiny meteorites hitting them all the time. Though, never hard enough to cause anything more than scratches. Some of the marks may very well have been reflections of other objects, but most of them are scratches.
Dan Hunter There are onboard systems to detect micrometeorites but there are some micrometeorites too small for it to detect fast enough to close the window in time.
+Warrior Son I think it's more about the danger there. An O-ring goes on your tap, and you don't have proper water for a while. O-Ring goes on your cupola module and you're venting the air you need to breathe, out into space.
+Warrior Son I think it's more over the fact that billions and billions of dollars and a portion of a 15+ year old internationally organized project is simply holding its atmospheric pressure because of 2 O-rings. In not just one, but 7 locations. When you put it like that it's much more humbling. It's like appreciating nature. You live in it every day, but somewhere, somehow, there's something that will always be amazing or out of the ordinary.
and yet some (including those engineers) still believe that the most complex structure, the universe (including animate objects), was not designed by The Engineer, but rather magically appeared out of nothing/always existed?!
+epposh Why would they believe something magically appeared out of nothing/always existed? That's silly. I prefer God as the explanation; at least there God always existed and made the universe magically appear out of nothing. You know why creation sounds less plausible than the current scientific theory? Because creation purports everything it says to be absolute fact, while science says this is our current best explanation. The sad thing is, you'll never know because when you die, you'll most likely just not be aware of anything for the rest of eternity. Just like before you existed.
nope. they would whip open a emergency procedure manual to check when needed. and contact ground control on how to proceed. because every section of the station can be sealed. so if one section becomes compromised, you can seal it off, like in a submarine and he is not in station all the time. what are you talking about?
In good engineering you want to go something similar to Occam's razor. The simpler, the better. This mechanical system has practically no parts that can fail, it is light, it works without power and everything used is REALLY thoroughly tested solutions.
Visceral Slays And if the 2 are identical they will wear at almost exactly the same rate. It is probably built to last decades after the planned end of the iss.
Visceral Slays The friction on those will be minimal. We are talking 5 revolutions or so to open/close it. And maybe done at max a few times per day. In contrast O-rings are used in machinery around the world, with operations in the thousands each day. And they still last years, if not for the duration of the machines lifetime.
I am losing faith in humanity by seeing people fall into the lies of the Freemasons. Wernher von Braun knew the truth, and he shows it through his tombstone. It doesn't matter, in the last days most of humanity will be deceived.
While those people get a lot of press, know that they are a very small percentage of people. One in one hundred thousand believe the Earth is flat, and some of those are just saying it to be contrary.
This was amazing. Even in 2020. I've owned Pitbull stands when I owned numerous Italian motorcycles, and I had absolutely NO idea that this man, who created this great device was so brilliant, and the man who engineered parts for the ISS. Pretty incredibly, his humility, not knowing his impact on the scientific community. So great! Thanks Destin
Benjamin Nenert Ok a O ring which is used as a mechanical seal on a moving shaft.What grease are they using , even the best Vacuum grease doesn't have the operating temp variations requirements that the ISS is suposed to endure. Just post the link to this wonder grease .
Jared Moore Really please tell what specific special O- ring they are using. Also like the ridiculous comment on pressure the pressure is supposed to be 7 to the minus 10 of a torr look it up before making stupid comments
They literally told you what to google. I googled "dynamic o ring" and found many makers. Marco rubber and plastic were the very first result. Try google, it's not as tricky as it seems.
Weird. Cant be dust/dirt. If its outside, then it would float strait. And inside it would float away from her breath. If its an object (ok, letz say UFO :) then why should it fly that weird and waste energy. Perhaps something wrong with the video?
Has anyone considered the layers of insulation required? Or is it just magic. If I had this insulation for my house I would burn up in the sun and freeze in the shade. I can only tell that this is a tin can with very thin exterior.
People are taught to think from movies and such that the difference between atmospheric pressure and a vacuum is a ton and makes things explode if there’s a leak, but in reality, it’s only 14.7 PSI. A bike tire holds more than double that. A small hole could easily be patched with a piece of duct tape on the inside if needed and. Think about a bike pump, those use O rings to contain pressure on a sliding shaft and can get to 100+ PSI
I don't really agree with you with "air being held from the space's vacuum with little o-rings"o-rings are way more powerful than you might think,as in many hydraulic systems,these little o-rings hold pressured oil, which has enough force to lift 1 ton and maybe more.
Many tons and also vacuum pressure. Just the a.c. system on a car where they live in a very harsh environment filled with highly charged carbon molecules and hot and cold cycles. As well as chemical contaminants.
True but would you rather trust an o ring to maintain oil pressure in your vehicle or trust it to mantain air pressure in a capsule surrounded by slow painful death?
The actual oil pressure to lift a ton could be fairly low, but I get your point... those rings only need to hold 1atm (14psi) - that's very low. Now designing them for a dynamic shaft is adding quite a bit of complexity but I'm assuming they're spec'd for light duty to keep wear from being an issue.

Stop using cheap O-Rings.
Mark Bowyer were do you get those NASA o rings
They are just rubber rings. If yours are continually failing then they are inappropriate for the job. Buy better quality and they won't fail all the time. Simples.
@Martin G Yeah, like they are not shielded by the metal around them. on the inside there's a shaft, on the outside a groove, there is no way they will bne damaged by radiation. O-rings and other rubber seals are used in countless aplications and when used properly they will last for a very long time. Take the seals in a car gearbox, often they are below the oil level, and yet a leak between the gearbox and the driveshaft is almost unheard of.
Those flimsy rings have been sealing stuff for decenia and they work fine.
@Martin G How much radiation do you think is up there? As has been demonstrated recently a small air leak isn't a big deal on the ISS, and it certainly isn't "life threatening" unless it's completely ignored. Rubber is used to seal air gaps everywhere, not just on the ISS.

+Cuda FX indeed, I don't know the actual atmospheric pressure inside the ISS, but assuming it's 1atm, they have to withstand "only" 1kg/cm^2 of pressure. That's not a lot
it's the same pressure as on earth at sea level, i just looked it up.
it surprised me a bit, though, you could propably get away with running a spacecraft at just 70% or so of that (the pressure you have on a 3000m mountain) and save conciderably in weight. it feels so counter inhtuitive, that submarinest have to me much stronger than an actual spaceship.

I work with Isolation tools in the oilfield, I "sting" large diameter pipes into a pressurized well 5-15,000psi using hydraulic rams, and the only thing that keeps the pressure from being released to the atmosphere is an o-ring with .127" thickness.
Jack Robinson how long is the o ring service life on the rigs ur running
I don't think you grasp the difference between vacuum and normal air pressure, and higly pressurized pipes of oil? You're lauching into space a lightweight structure not an oilrig.
Jack theres a difference between fluid dynamics and aerodynamics. First being the molecular structure size. Pneumatic cylinders cannot handle 5000psi utilizing the same o ring. Also, if air can pass through the rubber in your tire, it can pass through the rubber o ring in space. Thats why nitrogen is used in car tires more commonly today. I used to repair hydraulic aircraft jacks for Boeing with up to 100 ton capacities. Certification was required annually on all jacks and overhauling was done in 3-5 years depending on service. How many years have these o rings been in service?
@@Illusion-clock
LOL! There is NO DIFFERENCE , as far as the o-ring is concerned, if the differential pressure on either side of it is a higher positive pressure on one side and atmospheric pressure on the other side of it's seal
as opposed to atmospheric pressure on one side (or even a pressurized cabin for example) and a "vacuum" on the other side.
A vacuum is just a lower pressure in reference to atmospheric. But it is not a negative in absolute pressure.
I am assuming you are a flat earther or something?
HA HA
BTW, I use O-rings to seal between atmospheric pressure and vacuums, a DEEP vacuum at that, almost every day.
@@PsalmFourteenOne deep vac eh! 10E-17? Exposed to delta 500 degrees at any instance? Are your O rings factual? Or does Daddy work for NASA fraud? I'd rather have JESUS and LOVE then liars and hate!
That space guy when asked about a leak and brushes it off reminds me of a used car salesman.
Car salesmen dress better.
That's because space is a gimmick and it takes a salesman to get you to buy it.
the kind of used car salesman that has previously when hard in the paint.
The reason why he brushes it off, is that a small leak in the ISS would not be very dangerous. (I’m talking leaks that are less than 2 inches) because inside the ISS is an atmosphere of 1 atm (14 psi) so a leak of 1 inch will only have a pound force of 14. (Considering the pressure differential is 1 atm - 0 atm because space is a vacuum)
So you would be able to deal with that temporarily pretty easily. Thinking that it is a huge deal is like thinking that because you filled a tire to 30 psi it is going to explode if it gets a hole in it, when in reality it will just give a small hiss while air escapes until the pressure differential between ambient air and the tire is 0.
So a small leak on the ISS could be brushed off. The only difference is that instead of changing your tire and putting a new one on, you have to fix your tire while on the road.

If it's a lubricant that's avoiding its boiling temperature; seems very do-able
So, let’s be clear. Two tiny “O” rings stand between safe operation and catastrophic explosive decompression. Two tiny “O” rings. It even allows for the shaft to be able to turn so as to initiate the raising or lowering of the covers. Just that fact alone tells you that it can’t be airtight. And there’s one word that is not mentioned in any of this: VACUUM.
If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately. You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber.
As Pettit(?) claims, if a leak occurred, there would be a drop in pressure and there would probably be a plan- which he didn’t know- which would be implemented and would probably require a spacewalk to fix.
Sorry folks, but if a leak occurred everything and everyone would cease to exist in the blink of an eye.
😂😂😂😂😂
What do you mean "it cant be alright?" It clearly works or they wouldnt use it
"If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately." -Wrong.
"You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber. " - Wrong.
"if a leak occurred everything and everyone would cease to exist in the blink of an eye." - And wrong again.

In the interim, thanks for the laughs ! 😂😂
@@stephendaskey5128 Well, since you seem convinced you are right, I'll explain how you are wrong:
"If this was actually subjected to a vacuum test using the claimed internal pressure of the “ISS” and the vacuum level surrounding it, well, it would fail immediately." -
The internal pressure of the ISS is standard atmospheric pressure - 14.7 psi. Since the pressure around the ISS is very near 0 psi, the pressure differential is 14.7 psi. O-rings can withstand pressure differentials of several hundred psi.
"You cannot use rubber seals anywhere in a vacuum as they would fail because of outgassing from the rubber." -
If you use the wrong rubber then yes, it will outgas and fail. There are many different formulations of rubber and methods of making and treating it. Some of them do have major outgassing issues in a vacuum, but some do not, such as the high-vacuum fluoroelastomer O-Rings that anybody can order from McMaster-Carr. Naturally, NASA chose an O-ring material that can withstand high vacuums.
"if a leak occurred everything and everyone would cease to exist in the blink of an eye." -
Exactly how would "everything cease to exist in the blink of an eye"? As mentioned in the video, it would be a leak. You ever have a leak in a tire, or inflatable pool float? I have, and it's never caused a "catastrophic explosive decompression" and there's no reason it would on the ISS. If the O-ring suddenly completely disintegrated, it would likely leave a gap with an area less than a 1/2 inch hole. The ISS has a pressurized volume of over 32,000 cubic feet, it would take quite a while for enough air to escape out of a half inch hole before it became a problem, plenty of time to seal off the cupola. Add to that the fact that a failed O-ring would not suddenly completely disintegrated, but would actually develop an even smaller leak.
Of course, someone with "40 years experience..." should know all of that.
O-rings that move about are really not a big deal.
For example, any SCUBA regulator will have at least one O-ring that has 200 bars (3000 psi) on one side and 10 bars (150 psi) on the other, with a movable tube in the middle that, when in use, will move hundreds of times per minute. That thing will last for years without having to be replaced.
Compare this to the space station, which has 1 bar (15 psi) on one side and 0 bar on the other, and whose shaft moves what? 4-5 times per day? Sounds like a vacation compared to a SCUBA regulator...
+emdxemdx But it's freaking space dude. Way better than some regulator.
as i commented earlier, when you put space superstitions aside you realize that it is not as extreme as you think. the difference between in and out of the space station is really only 1 atm (15 psi). So the nearly 3000psi difference mentioned above is imo more impressive.
I have always found it odd that the general public is "scared" by the media about space being airless and how dangerous a hard vacuum is but they seldom mention the really scary things about space. Radiation ubiquitous and *LOTS* of it and dynamic temperature differentials that occur often and repeatedly. Hundreds of degrees in the span of an hour. Velocity differentials of many thousands of miles per hour between so many whizzing objects seen and unseen. 60 miles up you only have a 1 atm pressure change which is the same as a depth of 32 feet under water. Scary pressure changes are what submarines are all about.
Outer space is a challenging environment but not usually in the way most folks seem to perceive it.
Sometimes ... I fly out to the space station and peak in through the windows just to shock them all, lol. 😲 Makes me laugh every time.

CockatooDude Whoa...
I guess that's a possibility--but considering that there is no air to fight against such a movement or anything really, why would doing it more slowly help at all, in terms of not applying any centripetal force? Well wait, nvm I think you are right.
If it bangs on the window hard, that could easily create more movement than a slower, more controlled motion. Touche.
MetallicReg Aaahhh, that makes sense! Very good way of putting it. Chemical --> Kinetic energy
No one else gonna mention those two oddities spotted in that astronauts shirt? Hard to miss. Extremely eye opening for me.

As an aerospace engineering student, the gradual move from mechanical to electronic systems has always made me slightly uncomfortable. Call me an old fashioned sod, but I've always believed that simple mechanical systems are always more reliable than electronic ones
It's great to see that there are still places where mechanical over electronic systems are being used for their reliability ^^
Vectored Thrust You wouldn't like all our new aircraft then, all "Fly by wire" these days and it turns out atm they're much more reliable than the old mechanical ones.
I'd rather a cable with a bundle of wires and multiple backup systems over a metal cable that can fatigue, break, corrode, kink, etc.
Improper maintenance of a Pulley cable compared to a wire bundle, well, the wire bundle will go much longer than a Pulley without any maintenance.
Vectored Thrust Newer electronic systems are far more reliable than older mechanical systems. More back ups, quicker responses, less maintenance, smaller components...its why engineers have changed a lot of mechanical systems, be it cars, aircraft, engines of all sorts, to electronic systems.
Vectored Thrust
Good engineering will always be good engineering, whether is new or old-school it doesn't matter.
Vectored Thrust I'm an old fashioned sod too. and proud of it. the more automatic and computerized things get the farther they seem to be removed from reliability.
Austin Fifield I must say respectfully that that is how you get aircraft operators who can't fly a plane. they just operate computers.
I would've never have thought that there were direct mechanical connections to the outside of the space station, not to mention the fact that the vacuum of space is being sealed off by 2 tiny o rings . Thanks for enlightening me today Destin.
i am so much more proud of the pitbull stand in my garage now. this rocks!
That rocks.!!🤟😎
Isn't it just a basic paddock stand
The astronaut doesn’t know the protocol for a leak in a space craft in a vacuum of space? This is very hard to believe they were not endlessly trained in protocols and lends to his credibility.
I think they are all under some hypnosis. They really don’t have the appreciation for the fact that if they have cataclysmic pressure loss their bodies would be sprayed across the universe in less than a second.
Has anyone seen the door that closes this compartment off?
This space station must withstand more pressure than a submarine, should be build more solid than a submarine, but made of aluminum?
Some of this is just ridiculous. Do they have unlimited supply of air too?
How many times to they get deliveries? Air and water?
When I go camping we can’t last more than a week and that is pushing it.
To start don Pettit hasn’t flown is space since 2012 so he prob forgot certain protocols.
Second submarines have to withstand up to 30 atmospheres at 300m, space stations only have to withstand one.
Like on submarines they use electrolysis to generate oxygen from splitting water into hydrogen and oxygen.
Usually they get resupplied every 2-3 months. And when the send supplies there they pack it with stuff to last for 3 months
@@pukas7389 you mean the space station that there is no video diary of being constructed? That ISS that magically appeared in the sky with no fanfare, and no actual footage of how they made it
I almost teared up when the engineer came to the realization that his 20 year old design was in use on the space station. I can't imagine how rewarding that must feel.
17,000mph, not a problem for 2 o-rings.
o-rings made of Russian Rubber
+Kakarot7 From my understanding, those are two very different forms of heat transfer. Radiation is the transfer of energy that can occur in a vacuum, and without the atmosphere to shield astronauts and spacecraft it is being constantly pelted with solar radiation. Not having enough particles in space to transfer heat is okay because energy and heat are not being transfered through convection.
so what your'e saying is everything or mostly happening hear is heat transfer through radiation
Karl Tablay Yah, if an object gains energy or heat in a vacuum without physically touching anything then that would be energy transfer through radiation. That's why they put gold foil because that would reflect the majority of the radiation so it wouldn't damage the scientific instruments,
soooooooooooooooo interesting!!
The sad part is that there are still people in 2017 who think Earth is flat

I'm here because of the UFO you can see in the lower part of the middle window around 7:02
I realize how amazing the main topic of this video is; However the greatest point of enjoyment for me started at 5:42, where you see an engineer starting to realize for the first-time that a design he created was currently being used on The ISS. It appears to me that he is holding back his excitement while the conversation is taking place and the event is being recorded. Those moments where you get to see other people experiencing joy always seems to overshadow just about everything else. It's always a pleasure to get "SmarterEveryDay", especially when the process brings such joy to others.
-I'm not sure if I re-watched this video after so long to reacquaint myself with the information, or if subconsciously I wanted to watch that moment again.
Maybe I'm to synicle but I just saw the expression of a bussness man working out how awesome this is going to look on his advertising :p
I saw him cringing in hope he wasn't exposed, along with all of NASA. He had the face of a guilty man who had been caught, face to face with the Sheriff. Looked like he was ready and willing to spill the beans, rather than deny. A peaceful surrender. Then he realized this kid, and many other people, still believe the hoax! LOL!
so much anti-logic cramed into three lines - why would someone who once had dealings with NASA that ended years ago care about them being 'exposed'? why would this 'hoax' dedicated channel show it if that was the case? nothing about the system he made doesn't make scene in space so why would he consider it being 'exposed'? how would spilling about an 'conspiracy' be more peaceful then just excepting the existance of a think the people he is talking to have first hand experience of? etc. and who's a 'kid'?
Came here years later for the same reason. Dustin has an eye for stories.

actually, (bad science incoming) I think the station is pressurized lower than standard atmosphere. it's 14.7 PSI at sea level. I think it's reduced to lower the risk of a leak or blowout.

Two moments I shed some tears in this episode. When you told Charlie that his shutter was built into the space station by Italy, and when Astronaut Critoferetti did your outro.
Hi Destin! Greets from Italy - Nice to see Sam on this episode. Keep up the great work! Thumbs up for you.
Man that Pettit is one mean photog. I see they finally upgraded your camera to one with a higher shutter speed Pettit. You've finally captured the ball Earth with those elusive stars in the background. How you managed to capture such breathtaking imagery while shooting through space at 1.4 million mph plus going in 3 other directions at a different speed for each of those directions is absolutely amazing. You, sir, have one steady hand. For the next set of amazing cgi magic pics, throw some Crayola Crayons into the mix. Maybe a color by numbers Supernova in the distance.
It's fascinating to see the shutter mechanism work so smoothly because of microgravity. I though there would be like a gear reduction like you'd see on shutters on earth but not so. Super cool!

as an Engineer myself I couldn't help but notice those drawings were imperial, but virtually every country except America uses the metric system, seems like a recipe for confusion.
Yeah, there was some aircraft worth hundreds of millions which got broken cause one of the idiots used imperial system and noone checked it. :D
But using imperial units simply doesn't work. It doesn't. You say you are engineer? Convert one liter to one cubic decimeter. It's 1:1. Now convert 1 gallon to 1 sqaure feet. Some online coversion tools says it's 0.2614. But when you convert 0.2614 sqaure feets back to gallons, you don't get one gallon, you get 0,9997 of gallon. Which would be HUGE miscalculation in something like spacecraft.
Imperial units are remains of the medieval ages. Absolutely unusable in the modern days, completely unreliable for engineers. It was made to measure how big is your field and how much crop you grew. Not for advanced mathematics and unit conversions... Not for space travel. :D
So, yeah, since America DID manage to get a shuttle out of the atmosphere, it means they were not using imperial units.
NASA also uses metric. The drawings he has are probably the originals and NASA converted for him before sending off to Italy.
Look up the Mars climate orbiter ;)

Isn't Luke Schofield's brother an engineer too? Michael Schofield?
An astronaut using the words "probably" when talking about having a leak in the cupola? Really? One would think that there would be clarity as to what to do if there was leak while in space
The standard procedure would be to simply lock off the section that has the leak. Afterwards they either go fix it or they evacuate the station, depending on the damage.
Milkmaid, perhaps you could link to evidence that these "locking" sections actually exist and can perform the function attributed to them? Link to ISS leak protocols.It's all public domain. I'm here to help you "prove" space travel is real. :)
We know with certainty what happens with a leak in steam engine (for example), because we've seen it many thousands of Times, its well understood. We have a fair idea how it works under vacuum, but we dont have the reams of data. A good engineer is a cynic. It will probably work, but I dont *know*. You would be amazed how often "should" ends up "not". Always more variables out there to catch you. Dont trust a confident engineer. Only salesmen n marketing are confident, and they LIE.
@@arjovenzia lol, more often than not? Right, never a real problem in space at all.
He was referring directly the the procedure for replacing the cupola window mechanism, not what to do when detecting a leak. And as demonstrated this week a small leak in the ISS is not the huge deal people seem to want it to be.

so technology means budget?
No, we haven't lost the technology, we lost the money no money, no space that's simple and if you want another reason we haven't tried more than 15 times in the Apolo program is because of the solar wind, at the time we were ignorant and REALLY lucky than the sun was calm every time we went to the moon, but after we discovered than solar wind was a thing and a really dangerous one (can easily roast a man in its way to the moon or on the moon)

Why are the images faked from SS? Why has she got lots of hairspray in her hair?
At 6:00 in, I noticed marks on the window behind Samantha. Are those marks from miniature meteorites, stars in space or just a reflection from inside the module?
Dan Hunter Generally, none of the windows on the ISS are going to be spotless. There are always bombardments from tiny meteorites hitting them all the time. Though, never hard enough to cause anything more than scratches. Some of the marks may very well have been reflections of other objects, but most of them are scratches.
They may have opened a bag of Skittles too fast.
Dan Hunter It's more likely that's small pieces of metal from other satelites, rockets, etc. Debris. Than meteors :)
Dan Hunter There are onboard systems to detect micrometeorites but there are some micrometeorites too small for it to detect fast enough to close the window in time.
Dan Hunter Think of insects hitting the windscreen on the motorway ^^

"really? are you sure? they used my design? cause that was 20 years ago and..i..didnt follow it". uh huh.
3:22 that's the answer for absolutely everything in life.
+Warrior Son I think it's more about the danger there. An O-ring goes on your tap, and you don't have proper water for a while. O-Ring goes on your cupola module and you're venting the air you need to breathe, out into space.
+Warrior Son I think it's more over the fact that billions and billions of dollars and a portion of a 15+ year old internationally organized project is simply holding its atmospheric pressure because of 2 O-rings. In not just one, but 7 locations. When you put it like that it's much more humbling.
It's like appreciating nature. You live in it every day, but somewhere, somehow, there's something that will always be amazing or out of the ordinary.
He can be as majestic as he wants, but autistic, killed, starved and tortured people will disagree. Could the universe exist without you in mind?
and yet some (including those engineers) still believe that the most complex structure, the universe (including animate objects), was not designed by The Engineer, but rather magically appeared out of nothing/always existed?!
+epposh Why would they believe something magically appeared out of nothing/always existed? That's silly. I prefer God as the explanation; at least there God always existed and made the universe magically appear out of nothing. You know why creation sounds less plausible than the current scientific theory? Because creation purports everything it says to be absolute fact, while science says this is our current best explanation. The sad thing is, you'll never know because when you die, you'll most likely just not be aware of anything for the rest of eternity. Just like before you existed.
So this astronaut who up in this station all time , doesn't know what the emergency procedures are ? Laughable.
nope.
they would whip open a emergency procedure manual to check when needed. and contact ground control on how to proceed.
because every section of the station can be sealed.
so if one section becomes compromised, you can seal it off, like in a submarine

Wait, why can't the shudders be operated with an electric motor? Is it mechanical in case of electrical failure?
Probably because they don't want million dollar space walks to replace a burnt motor.
In good engineering you want to go something similar to Occam's razor. The simpler, the better. This mechanical system has practically no parts that can fail, it is light, it works without power and everything used is REALLY thoroughly tested solutions.
+Ricki Nielsen there is friction on the o ring, so that will eventually fail.
Visceral Slays And if the 2 are identical they will wear at almost exactly the same rate. It is probably built to last decades after the planned end of the iss.
Visceral Slays The friction on those will be minimal. We are talking 5 revolutions or so to open/close it. And maybe done at max a few times per day.
In contrast O-rings are used in machinery around the world, with operations in the thousands each day. And they still last years, if not for the duration of the machines lifetime.
I love how Destin was blown away by the fact, it's only O-ring seals protecting you from the vacuum of space. It's only 1Bar. =)

5:00 The deception of it all
Absolute joke :D
Calm down, the pressure difference is only 15 psi, bike hand pump seals can do more than twice that and move way more.
People are taught to think from movies and such that the difference between atmospheric pressure and a vacuum is a ton and makes things explode if there’s a leak, but in reality, it’s only 14.7 PSI. A bike tire holds more than double that. A small hole could easily be patched with a piece of duct tape on the inside if needed and. Think about a bike pump, those use O rings to contain pressure on a sliding shaft and can get to 100+ PSI

Ya know, scratches on Windows exist, right?
I don't really agree with you with "air being held from the space's vacuum with little o-rings"o-rings are way more powerful than you might think,as in many hydraulic systems,these little o-rings hold pressured oil, which has enough force to lift 1 ton and maybe more.
Many tons and also vacuum pressure. Just the a.c. system on a car where they live in a very harsh environment filled with highly charged carbon molecules and hot and cold cycles. As well as chemical contaminants.
True but would you rather trust an o ring to maintain oil pressure in your vehicle or trust it to mantain air pressure in a capsule surrounded by slow painful death?
Nate Lav oh, I’m sorry, I replied to a wrong comment. I accidentally closed the thread.
The actual oil pressure to lift a ton could be fairly low, but I get your point... those rings only need to hold 1atm (14psi) - that's very low. Now designing them for a dynamic shaft is adding quite a bit of complexity but I'm assuming they're spec'd for light duty to keep wear from being an issue.
David Kuhn I believe the pressure may be around 4 psi. No need for full atmospheric pressure.
Seems too good to be true. cant deny the laws of thermodynamics and entropy. "hurr durr, we can just fix it - maybe a spacewalk" unreal
