i do however wish people will compare the space x suits to other suits that are in the same category and not just the exterior suits made
Yeah, it`s like comparing swimming shorts to winter clothing. Pointless apart from $ from ads
Yes. Other than the Ticonaut flight suits, th e pictures all compare the SpaceX Flight Suits to NASA & Roscosmos EVA Suits. They just aren’t comparable. The narration does a good job differentiating; however, the visuals are lazy.
I wish people would watch the whole video before criticizing.
@@ScottElliott888 , I did. The narration was fine; it made a distinction between IVA and EVA suits. At the same time, however, the b-roll footage did a terrible job representing the narrative.
@@michaeldemarco9950 Not to mention the misleading Title and Thumbnail.
Explains the difference between IVA and EVA suits ✅ Talks about NASA "pumpkin" suits but shows B-roll of an EVA suit❌
Yeah, for a video meant to compare and contrast SpaceX's IVA with NASA's I don't think I saw one picture of NASA's IVA's from the shuttle era. Very weird.
They're just balancing out the movie adaptation of The Martian, where our protagonist spent the entire movie doing EVA in his IVA suit.
Virtually EVERY time other "flight suits" are mentioned, the video actually shows some form of EVA suit.
Very frustrating & misleading; despite starting with a quick IVA vs. EVA definition, it's wrong to repeatedly compare the minimalist safety suit of the Dragon to all the past and future NASA designs made for long-term work shifts outside the ISS that require rugged gear and complete stand-alone environmental life support. And suits that can fit a big range of folks on station is a plus too. SpaceX is doing awesome stuff with innovative designs, but don't misrepresent the huge additional challenges that NASA spacewalk workers must face which sheltered Dragon passengers do not.
One of the bonuses of the space x design is AFAIK that it is individually tailored to each astronaut, it is in each case no larger, or more bulky, than it needs to be. Each person takes one up, uses it, and brings it back. HTH
You forgot that he compares the SpaceX flight suit to the NASA EVA suit. He mentioned the orange flight suit but only shows the EVA suit.
@@Ava31415that’s exactly how each NASA suit was made. They were all tailored to the specific astronaut wearing them
Well yea but hey remember space x is a company thats getting things done. a EVA suit isnt to important and yea one is real and the other is in development we get it. but it doesnt mean he wont do it so lets find out. i mean hey nasa is looseing there edge over space x every day. reusablity is a game changer. plus nasa never really had a good IVA suit so it would have to be compared to the standard which is nasa eva suits.
@@Mystiverv Not the EVA suits. Those are made of set of standard modular size parts "small, medium, large" and so on. Then on earth each crew member is just fitted and tested with "okay with you best fit combination is medium torso, small helmet, large shoulders, medium arms and small gloves" and so on. Apollo moon suits were custom made and fitted per astronaut, but those were consumable items anyway. By the end of the weekend on surface the suits had started to leak guite a bit with moon regolith tearing upon the soft fabric and rubber pressure joints. The new moon suits are ment to be maintainable, modular, station suits. Maybe at times having to swap out specific part or other on it becoming too worn out. However a more permanent suit, rather than the consumable item Apollo suits were.
I have a similar complaint that lestagez described. You are comparing the SpaceX IVA suit to the NASA EVA suit. Why not compare the SpaceX IVA suit to the NASA Space Shuttle orange jumpsuit (IVA)?
Apparently because he cares more about rhetoric than fact...
You forgot about cooling, dealing with temperatures outside the vehicle is more challenging than inside.
There is already a fantastic fabric made from UHMW (Ultra High Molecular Weight polyethylene) that, by the nature of the very long molecule strands, offers high tensile strength without sacrificing flexability. I've used an 8 way woven version of it with a very thin layer of UHMW heat set to the back in epoxy encapsulating applications where it gets drawn under a near perfect vaccum, then pressurized to 20 to 25 PSI. The vacuum removes all the air from the area receiving the epoxy, then the epoxy is introduced to the space in a way that it fills all of the small areas of the cavity. Once the cavity plus the overflow space is full, the system is then pressurized to compress any voids or air pockets that formed. This squeezes any air pocket down to less than 1 percent of its volume while in a vacuum. It's a fantastic system made possible by the UHMW fabric. An additional bonus property is that noting sticks to the UHMW, so wear and cleanup was a breeze. I think this property would translate over to a lunar EVA suit very well to reduce suit wear due to the lunar dust.
Even better than polyethylene fabric would be tungsten coated polyethylene. If the thread had tungsten sputtered onto it before being woven then the shielding value would go up quite a bit. Tungsten is even better than lead for gamma/x-ray shielding. Polyethylene is good for neutrons but not for gamma or x-rays combining the two is critical.
Alignment with the body of the wearer also allows the suit longevity, and makes fixing simpler.
This video is confusing IVAs (Intervehicular Activity) with the EMUs (Extravahicular Mobility Unit.) These are two very different technologies. With NASA holding a competition for the best IVA.
Thanks for sharing this, interesting 👍
The biggest flaw/drawback of the SpaceX suit is the helmet. You get zero flexibility to swivel or crane your head, and this is compounded by a visor design that limits field of view more than pretty much any other suit design. I like to think that SpaceX are aware of these shortcomings-especially as they contrast with competing designs such as the one intended for the now-almost-defunct Starliner-and will be addressing them when it comes to the actual EVA suit. Other than that, yeah, the SpaceX suit _especially_ puts the hopelessly out of date taikonaut suit to shame. I like to think China is torn on just how much of SpaceX's suit design they should steal.
missed opportunity to have the classic halo eva helmet with a full head visor.
Best comment: "I like to think China is torn on just how much of SpaceX's suit design they should steal"
That would be because the current iteration of the SpaceX IVA suit is not intended to be used during EVA.
When you can twist at the waist and shoulders like the SpaceX suits you'll see fine.
@@whotknots Exactly my words. SpaceX has yet to reveal any other design for EVA, be it for space, the moon or mars. When they do, you can expect it to perform at least as good as NASA's suit.
I'm wondering why mechanical pressure suits aren't looked into more; the only part that would have to be pressurized would be the helmet, saving a lot of air and lengthening flight times.
I can explain that a little bit as I am ME studying life support systems for a career in spacesuit engineering. The issue with mechanically pressurized suits is the difficulty in even pressurization across the human body as well as how this would work with the current liquid cooling systems we use for temperature regulation today. Fairly recently Texas AM's Dr Ana Diaz Artilles has been spearheading research into this area with the SmartSuit, that would reduce amount of gas generate pressure and thus the pre-breathing time. Aside from that limited research has gone into MCP suits given their complexity and well established method of gas generated pressure we use today. Nonetheless I agree with you in that MCP suits have a lot of potential in the future and believe they can help resolve a lot of issues in susceptibility to decompression sickness and the age old issue of mobility/flexibility. Short summary but hope it helped shed some light on the subject. Definitely aim to work with them in my career.
Almost none of the suits you showed were space flight pressure suits for launch and reentry (NASA ACES). Almost everything you showed off was an EVA suit. Try doing an EVA in a pressure suit and I think you'll have a bad day. NASA's ACES suit has about 10 min of air in it, SpaceX's suit looks like it has even less.
My apologies, SpaceX; space suits resemble hazmat suits, the coolest space that could serve as a road-map design. Check out;, the movie "The RedPlanet", with its calibrated-computerized helmet, and cell-like oxygen vets attached to the suit & the color of the suit is so dope which is navy blue. Space suits are traditionally white because of the lack of gravity. We can adjust the suit to that.
In the moon they'll have to use the cocoon style the russians lunar suit had. When they slip out after a moon walk there should be a spray or vaccuum system where the back of the suit docks into entry airlock so that it blows away regolith.
I wonder if an EVA suit that exists only inside the airlock on a bulkhead, they enter through the back. That way the regolith on the suit only gets into the airlock, but no farther. Connecting the life-support closes and seals the suit for detachment.
your going to need an electro static charge applied to the regolith and then have the same repelling charge added to the equiptment, as the amount of activity is going to kick up a lunar atmosphere which will be a major problem for lunar dust storms and visibility issues. But hey its gonna be fun to see the moon grown an atmosphere over time.
@@yamiomo7392 so much for that idea. :/
@@brianj.841the only difference is that I've included a spray system to wet the regolith on the suit's hatch, therefore ensuring it won't spread via the ventilation system and be easier to clean with a cloth or paper towel.
@@i-craftsdesign3175 If you're talking about a moon lander, water is heavy. Even recycling can only do so much.
we are truly living in an age of wonder when so many technologies and human exploration all coming together. If we can get rid of all these endless pointless wars and remove the people wanting this then humanities boundaries will rise even further.
I can't wait for the Atimus 3 launch.😊
This is damn near technology from The Expanse & that's incredible!
7:50 there were Gemini and Apollo missions that orbited higher than that.
Yeah, you have to wonder if they did any research at all for this video.
No earth-orbit Apollo orbited higher than that, only Gemini 11 did.
1:52 - INCORRECT! The Soviet center cosmonaut had a literal "faucet" between his legs that he was required to close manually. They missed that step on the check list and accidentally committed suicide. This was a procedural error caused by central planning control freaks and not a hardware malfunction. The valve worked perfectly when tested after the landing.
Source or fake
@@flynntaggart7216 According to Wikipedia that has citations. There was a valve under the seats that could have been used to stop the leak. So, sort of true. But the valve was inaccessible to the seated crew. The only crew member that was wearing a bio monitor was in cardiac arrest at 40 seconds. To make matters worse an autopsy showed that after just 20 seconds they would have passed out from lack of air pressure. Holding your breath at 104 miles isn't a thing, you breath out and lungs collapse. It isn't a vacuum but it is close at .0007-.0003 psi vs 14+ psi at sea level and 4.84 psi on Everest. The failure was attributed to 2 sets of explosive bolts that should have fired sequentially but fired simultaneously. This caused a valve that should have balanced the pressure to remain open. It killed the crew and the automated landing systems returned it to earth safely. That is how we know what happened. For more details read the wiki article it is pretty good.
@@EthosAtheos What wiki article is that? I couldn't find it under the Space suit article.
@@VVayVVard it is under the Soyuz 11 article, about mid way down.
Good segment, thank you.
Thanks again for good stuff.
So many real reasons lately and I love it.. So many real reasons lately and I love it..
At 2:25, that was anEVA suit.
Your video is filled with inaccuracies: You compare SpaceX IVA suits with NASA EMUs and Russian Orlan suits - both of which are EVA suits. If you were doing a fair comparison you would have shown the orange Shuttle ascent flight suits. An actual EVA suit has to provide a far greater range of motion, operate for hours, provide MM/OD protection, deal with varying light levels and themal conditions, allow for bending without fatiguing the wearer, etc. The SpaceX suits are simpler and cheaper because they don't have to do as much. But put them in a real working environment where you can't tailor every suit to a single user and they get much more complex and expensive.
Personally I prefer the older style of flight suit aesthetic wise. It feels a lot more technical and iconic, which is what astronauts are. The Space X ones look like something from a generic space movie instead of some of the most technical PPE in the universe.
Ya I agree. They look totally M Mouse.
What if they made a backpack with all that life support stuff that connects to the connector for the umbilical cord so they wouldn't rely on an umbilical cord
3:40 . Technically this process wouldn’t be reverse engineering. Reverse engineering is trying to figure out how something was engineered by someone who didn’t do the original design. It’s really just regular engineering what they did. Analogous to an architect ‘designing’ a building and the engineers figure out how to make it work. Entertaining program
Dude the Van Halen belt rocks
not a single photo, drawing, render or in fact any substantive information at all on the Polaris EVA suit design, cost, release date or specifications.
Great content. Haven't seen this issue updated. Thanks
U TV Vtec
We definitely need a suit using molecular technologies.
Always reminded me of my motorbike gear.
Good to see a Cameo appearance of EveryDay Astronaut at about 7 minutes in...
Gold coated nylon or kapton which is orange-brown by nature? Metallic gold gets pretty hot in sunlight in orbit.
Be interesting to have a top half of a space suit made out clear material. Then layered inside and outside from that. It would save on seams to a conventional clear helmet window.
How long can someone survive in space with the IVA suit??
even the thumbnail is wrong, the first suit is the radiation suit that is worn inside of the rocket or station, while the second suit is an actual spacesuit that you could survive in the vastness of space
Thanks for this. I generally like your videos, but I was surprised that you left out a vital aspect of space suits. You touched on them being like a blown-up balloon, but not what this does to the joints. Unless the suit is very carefully designed, it will want to blow up to resemble a starfish, with all the arms & legs straight. It's very difficult to make the suit have joints that allow the astronaut to bend their knees & elbows with minimal force, since the natural inclination of the pressure inside the suit is to keep everything straight. The joint has to be exactly aligned with the body & its flex-angles, & it must counter this natural tendency to keep the joint straight. That's a neat trick, especially if you want to keep it pressure-tight at the same time. Shoulders & hips, which use ball & socket joints on humans, are even harder.
Is the September date still holding for the Polaris Dawn test of the new SpaceX EVA suits?
It is for december (see Rocket Launch Manifest)
12:28 Materials rich in hydrogen atoms confer partial protection, but you also need lead or other materials with high atomic number to protect against X and gamma rays.
Very Good Recap
At 8:13 now that's a spacesuit!
Great content as usual.
But the hole purpose of the suit is if something goes wrong with the life support so if it's function is tied with the life support it isn't worth it anymore right
Wait if SpaceX were developing EVA suits why didn't they try to get NASA contracts as NASA are instead paying Axiom Space and Collins Aerospace billions to make new suits for NASA. Both companies are getting paid to make one set for space walks and another set for lunar landings.
They should use those Delaware ladies that sewed the NASA suits 50+ years ago (ILC Dover)... ;-)
Keep comparing SpaceX IVA suit vs NASA EVA suit
Very good nice and clear.😀
I'm so excited for the next 20 to 30 years with everything going on from elons work to nuclear fusion power I'm actually look g forward to the future instead of dreading it now. Thanks Elon and his team for giving hope once again to humanity
The current crew dragon suits look like Halloween costumes.
Hey great green lands
Sounds like a Stockton Rush designed space suit
Wow what a video! Thank you so much and keep going!
how can it be vacuum tight with a zip lol am i missing something >?
Those SpaceX suits still make me think of Gundam every time I see them.
I sure liked it!
So many real reasons lately and I love it.
Comparing how easy it is to get into a SpaceX pressure suit vs. how hard it is to get into a NASA EMU ...
I wouldn't trust that zipper to save my life.
🚀
Nice
First comment and view hehe
And like
I like everything about the SpaceX suit except for the boots. Looks like something a Shrimp boat captain would wear.
Wait a minute.. Dragon can carry the eva pack in the trunk.
NASA: "We have to contend with screws and nuts that cost $1000 each!"
It was a really good comparison here. When exactly though is the Polaris Dawn mission supposed to happen?
I thought they would develop a jetpak/lifesupport system...
Is it just me or does the SpaceX suit look like a Mobile Suit pilot?
I'm so excited and can't wait to see the new Space Suits.😱😱😱😱
And if power or air in the dragon capsule fails or get contaminated. They are dead. They have no independent back system
They 'use' the EVA suit (NASA iteration) to float around space....... Well that's an interesting statement indeed??
Well I guess you could use a version of Tesla robot for EVA using human telepresence control systems to build and repair system hardware out in space.
Old space suits are so much cooler than anything SpaceX has made, theyre so iconic that you could show a child and theyd recognize its a space man.
So the point of the suit is to keep the passenger fine if the system of the capsule fails but they removed all additional systems to backup the capsule for the sake of looking good.... Doesn't seem very safe to me, but I guess Lord Musk knows better than Me and NASA 😅
Classic musk: form before function.
Did you guys here that Jared will go to the highest point nobody has ever flown in space that is to the Van Allen belt. So "if" we been to the moon before that means humans been further, then the Van Allen Belt correct 🤔
An IVA suit that has an umbilical to the life support in the capsule is very common, but to me it makes little sense. The reason I say this is that of all the things that could go wrong, most of them would not be survivable with a tethered suit. Let's say a window blows out. You can't renter that way so you have to dock. If the vehicle or station you are docking with has no air lock behind the docking hatch, just opening the door would depressurize them. OK then what if it did have an air lock? Then you would't be able to come through the door without detaching. There are countless senecios like this where death would not be prevented, only be delayed a few hours. What if the docking failed and the mechanism was hopelessly jammed together, so the ship couldn't depart. What if the life support of the vehicle itself failed? The only situation I can even think of where life would be saved would be if the cabin depressurized on the way to de-orbit, from a small hole. If the suit had the capacity to replace the umbilical with even a mini back pack, say giving 30 minutes of pressure and power, then everything changes. They could EVA to another spacecraft that had a hatch that didn't match. Most rescue approaches would work.
A simple safety valve would allow the tether to detach for the very short period of time it would take to transfer into tge airlock. And tge Nasa suits can not long provide life support! You at best would have a very short time to survive in one if the vehicle life support failed.
Watch 2:13. The suit is not made for space but rather sent and desent maneuvers.
The suit it made to save life. My point is in most situations it won't. It will only delay death by a few hours. @@human0685
It helps with all kinds of cabin decompression. If it is bad enough that you cant reenter: well, dock to the station. I dont see your point why you cant dock to an airlock ( or better, use the room behind the docking port as an airlock). Listen, it is done this way because it makes sense. This isnt some wild idea someone once had and never tested. EVA suits are too bulky to be worn all the time (although technically Apollo wore their EVA suits as IVA suits, but also with an umbilical while in the capsule). And IVA suits are needed, thats what Sojus 11 taught us.
I think Elon wanted his astronauts to resemble the Power Rangers of his youth.
Why? PR. Space X suits look line the capital peace keepers on the Hunger Game.
Mars has atmosphere simular to Earth, no space suit needed
If it wasn't for space x giving copetetion NASA would be nowhere today . And I think that the suit should have alien tech inside of the helmet and a Lazer on the shoulder like predator .
Key word "flight suits"
Good video, but at 10:10, the tensile strength of 350 pounds means nothing to 95% of the planet.
Cosmic radiation eh... They come back "Fantastic" and I'm going to have questions.
The real reason
STS-31 reached 621km in 1990. Polaris wants to reach 700km.
7:50 what do you mean by the farthest humans have ever flown? Lol. I thought humans gone to the moon?. Which would mean that humans already flown past the “van Allen belt” please explain because I’m genuinely confused.
SPACEX is leaps and bounds beyond anyone else!
Well yes, in the area of hype.
@GuyBlondWithOutGod Oh right. Regular reusable commercial rocket launches and American rockets finally putting people back in space are all hype, are they? And just who else is doing it as cheaply as them?...🤔
I mean, space x is not doing anything we couldn't do 40 years ago. They just made a business out of it. If it is cheap we don't know. Bc I'm pretty sure SpaceX is not making a profit.
@@slaapkonijn58 yes, tell everybody that you think spaceX is not making any profit.. this will open peoples eyes to the truth. but among us, dont tell anybody: spaceX Ebitda is at 38% lets just pretend we dont know and everything will be fine. just show people the 40 year old videos of rockets landing on drone ships, and people will see that spaceX is nothing but a huge fail, like tesla..
@slaapkonijn58 Then why didn't we build reusable liquid propelled boosters that could land precisely 40 years ago? And how the hell would YOU know about SPACEXs profitability, Mr "business" man?
Will they be in space or in Hollywood ?
Please, be more exact, which kind of nuclear radiation you are talking of. When you mention the hydrogen, you mean protection of particle radiation, like protons or neutrons. Alfa and Betha are reduced already by any layer of material. What you not mentioned is the protection against Gama radiation. This could be achieved, imho, with magnetic fields.
SpaceX suit is just a flight suit Not an EVA suit.
Let's move on from SpaceX space suit, until some newer or improved innovation comes around.
My favorite drop from this channel... so far !! Thank you !!
I mean I don’t even think space x suit would do anything if there’s a failure it’s mostly a pressure suit so you don’t get turned into a a pancake when you get sent up ?…
Harry could’ve disarmed Lockhart during his monologue, the spell knocks him against the wall and he falls unconscious on top of Ron’s wand breaking it (this way Ron still gets a wand that chooses him for PoA). It also triggers a small cave in that separates Ron and Harry and now we’re back on track again.
?
No need for a 1,000 lb line. They did not know what they needed, we do now. 300 lb is plenty. And chances are they will never have more than 30 lb. I don't like the location of the umbilical. When you are moving your leg, you don't want that flopping around. Best, would be somewhere on the torso, that you can both see well and access easily...ideally with either hand, in case an arm is injured. 9" above the belly button sounds ideal.
So that’s the “REAL” reason. I was tired of hearing about the fake reason.
Those are huge ears man
They are exactly that they are flight suits not space suits that go out in space
lower the cost to make space travel for pheasible
When the mining companies get up there. I'm not joking.
@@i-craftsdesign3175yeah when we start graping the solar system were gonna need as many monkeys as possible for it . At least until we can get robots to do it cheaper
Nice work. 👍🏻
