The Real Reason SpaceX Is Developing A New Space Suit 

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

Explains the difference between IVA and EVA suits ✅ Talks about NASA "pumpkin" suits but shows B-roll of an EVA suit❌

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)?

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.

You forgot about cooling, dealing with temperatures outside the vehicle is more challenging than inside.

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.

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.

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.

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.

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.

7:50 there were Gemini and Apollo missions that orbited higher than that.

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.

At 2:25, that was anEVA suit.

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.

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

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.

At 8:13 now that's a spacesuit!

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.

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

Alignment with the body of the wearer also allows the suit longevity, and makes fixing simpler.

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.

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.

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.

Thanks for sharing this, interesting 👍

Gold coated nylon or kapton which is orange-brown by nature? Metallic gold gets pretty hot in sunlight in orbit.

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.

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.

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.

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

Always reminded me of my motorbike gear.

Is the September date still holding for the Polaris Dawn test of the new SpaceX EVA suits?

Comparing how easy it is to get into a SpaceX pressure suit vs. how hard it is to get into a NASA EMU ...

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.

So many real reasons lately and I love it.. So many real reasons lately and I love it..

I can't wait for the Atimus 3 launch.😊

This is damn near technology from The Expanse & that's incredible!

Thanks again for good stuff.

Good to see a Cameo appearance of EveryDay Astronaut at about 7 minutes in...

How long can someone survive in space with the IVA suit??

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

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

Good segment, thank you.

Very good nice and clear.😀

SpaceX suit is just a flight suit Not an EVA suit.

I like everything about the SpaceX suit except for the boots. Looks like something a Shrimp boat captain would wear.

Hey great green lands

The real reason

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 🤔

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.

Mars has atmosphere simular to Earth, no space suit needed

The current crew dragon suits look like Halloween costumes.

Very Good Recap

They 'use' the EVA suit (NASA iteration) to float around space....... Well that's an interesting statement indeed??

Sounds like a Stockton Rush designed space suit

I sure liked it!

Keep comparing SpaceX IVA suit vs NASA EVA suit

Wait a minute.. Dragon can carry the eva pack in the trunk.

Classic musk: form before function.

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.

Those SpaceX suits still make me think of Gundam every time I see them.

I thought they would develop a jetpak/lifesupport system...

Let's move on from SpaceX space suit, until some newer or improved innovation comes around.

So that’s the “REAL” reason. I was tired of hearing about the fake reason.

Good video, but at 10:10, the tensile strength of 350 pounds means nothing to 95% of the planet.

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.

NASA: "We have to contend with screws and nuts that cost $1000 each!"

We definitely need a suit using molecular technologies.

Nice

I think Elon wanted his astronauts to resemble the Power Rangers of his youth.

how can it be vacuum tight with a zip lol am i missing something >?

It was a really good comparison here. When exactly though is the Polaris Dawn mission supposed to happen?

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.

And if power or air in the dragon capsule fails or get contaminated. They are dead. They have no independent back system

I'm so excited and can't wait to see the new Space Suits.😱😱😱😱

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 .

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 ?…

🚀

Umbilical cords in space and space debris....

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.

STS-31 reached 621km in 1990. Polaris wants to reach 700km.

SPACEX is leaps and bounds beyond anyone else!

Why? PR. Space X suits look line the capital peace keepers on the Hunger Game.

Cosmic radiation eh... They come back "Fantastic" and I'm going to have questions.

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 😅

They are exactly that they are flight suits not space suits that go out in space

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.

Is it just me or does the SpaceX suit look like a Mobile Suit pilot?

Was sitting here thinking, I cannot stand Musk as a person (to be fair, never met the guy, so feel how you will about my opinion), but I do grudgingly admit that some of his efforts are nothing short of... well, wow.

Very good illustrations and explanations. Thanks.

Key word "flight suits"

How do the suits protect the wearer from gamma rays? The Nasa explanation for the moon walk suits are lame a. f. One article says all the astronauts were 'extremely lucky'. 😅

👍🏻🙏🏻❤️

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.

lower the cost to make space travel for pheasible

Damn.. those space x I.V.A astronauts are packing some heat. Check out that IVA bulge😂😂 makes sense though right? These dudes must have HUGE balls to jump on a giant bottle rocket, point it at mars and light the fuse😂😂😂

Those are huge ears man

In the video you compared the current Space X IVA suit to all the other EVA suits not the NASA IVA suit to the Space X current IVA suit not a apples to apples comparison. You can't make a true compression of Space X unit Space X makes an EMU.
