A Brief History of Space Suits

[@DKiSAerospaceHistory]

Some small corrections: 1: the astronauts did not use the OPS while disposing of the PLSS. Rather, they were tethered to an oxygen supply within the LEM while they disposed of the PLSS portion of the backpack. 2: diving suits do not maintain a standard sea level pressure. They are kept relatively close to the pressure of the depth that they are used at.

[@kristinfrostlazerbeams]

@@DKiSAerospaceHistory unless they are those pressurized suits with the tether. Deep sea divers apparently use these suits because it keeps them from getting nitrogen poisoning.

Regarding diving suits versus space suits: Diving suits require the same internal volume as pressure outside changes to hundreds of atmospheres. A spacesuit only requires a difference of at most two atmospheres. Since breathing is the only requirement and we breathe 20% O2 at 1atm you could theoretically get away with just 0.2atm at 100% O2. This was done in early designs of space capsules but cancelled after a certain fire. A leak in a high depth diving suit will instantly kill whoever is inside, the water will expand inwards at the speed of sound of the medium (1400m/s) and the mass flow rate is determined by the pressure (per 10 meters of depth ~+1atm of pressure) This combination is a guaranteed millisecond death. A leak in a spacesuit will move at a glacial 340m/s and a pressure of 1atm. note that these are rough calculations, obviously the diving suit wouldn't kill you at low depth and the spacesuit requires additional isothermic protection.

[@DougVanDorn]

The concept of providing a lower-pressure, pure O2 environment wasn't canceled. What was changed in Apollo was pumping the cabin up with full sea level pressure pure O2, this changed to 60% O2 and 40% N2 on the pad after the hatch was closed, to lower the risk of fire. The crew was breathing pure O2 in their suits from a couple of hours before launch, though. During launch, as the rocket rose and the air pressure decreased outside, the 60/40 cabin atmosphere was vented out and replaced with pure O2, until the cabin was at about 5psia (more like 30% of sea level pressure), and as close to pure O2 as possible. The pressure suits also relieved from sea level to about 5psia at the same time. From that point, up until they landed on the ocean, Apollo crews were in a 100% O2 environment at roughly 5psia. The lower pressure, plus removal of flammable things like nylon from the cabin, reduced fire risk enough to safely fly the missions. It also had the side effect of letting Apollo crews put on their suits and backpacks, depress their spacecraft, and go right outside, without the need to pre-breathe or adapt to a lower pressure. In fact, during EVAs, the suits tended to be inflated to about 4.1psia, very close to the 0.2atm you mention. That kept the suits from being so rigid it was hard to move in them. The biggest developmental issue Axiom has with these new suits is maintaining a 10psia mixed gas atmosphere in the suits and yet make them so you can move in them. I wish them luck.

[@-yttrium-1187]

@@DougVanDorn I stand corrected, I thought they completely abandoned pure o2 atmospheres after that. I had no idea they vented down to high o2 concentrations. Do you happen to know wether axiom uses helium to achieve greater partial pressure? I cannot find details regarding their gas mix. Though it would be a pita if someone's accelerometer failed due to helium poisoning. I guess we could listen for helium once they put on their suits. Yeah, the main advantage of not using nitrogen is preventing the bends when transitioning pressure differences.

[@oremooremo5075]

@@DougVanDorn Hmm I was wondering if maintaining enough O2 partial pressure for breathing is the criteria needed, I'm wondering how much leeway is there to lowering it to reduce the effort on the spacesuit. I'm guessing not much since we can pass out at anything lower than 18% O2 concentration Also breathing is one thing and maintaining pressure on the body is another, what is the lower pressure limit you could keep your body at and still stay alive, I was envisioning a spacesuit that divides up the head and body into seperate pressure compartments, the head is fed O2 at 0.2atm and the body is kept at a lower pressure hence flexible, about the chest problem, maybe that's kept restrained mechanically or maybe put in the same compartment as the head I'm guessing I'm proposing some sort of engineering nightmare or there are other issues unbeknownst to me. But it is a fun concept to explore

[@masterzoroark6664]

(Death at depths reminded me of that one Mythbuster episode where they confirmed that yes- you can get squeezed into your ol'timey diving helmet if your suit fails while diving)

[@-yttrium-1187]

@@oremooremo5075 This sounds ridiculous but our skin can practically survive the vacuum of space. Again, assuming you're not breathing certain gases like nitrogen, which could potentially boil off. So one of the next limits would be the vapor pressure of H2O and maybe some other dissolved gases that I'm not aware of. So, why didn't the apollo astronauts boil alive when their body was at 0.2atm? Because to achieve a vapour pressure of 0.2atm, water would need to be around 60c. Or, if you want water to stay below its boiling point at 40c, you would need 0.0728atm of pressure. So just 8% atmospheric pressure will prevent boiling unless you're running a fever. Also, certain human beings have been known to be able to function on the partial o2 pressures on mount everest, which is roughly 0.4atm with o2 being about 0.1atm. So yeah. your "Spacesuit" for the ideal space marine could function on just 10% normal pressure.

[@TiagoNugentComposer]

1:06:16 A note about the suit from The Martian - it looks to me like it was inspired heavily by the MIT BioSuit, which uses a *very* tight fabric to provide mechanical pressure instead of air (i remember watching a documentary when i was younger where mike massimino got to wear one and said that he "felt like an italian sausage", although i dont remember which one it was.) Im guessing that the actual mechanical pressure layer is worn on the inside, with an outer layer that houses some kind of temperature control system which would explain why it doesnt look super tight in the movie. The vacuum EVA suits are much bulkier and basically just look like the EMU suit with some extra hinges for better mobility.

[@DougVanDorn]

Quick correction -- when the LM crews jettisoned their PLSSes, they didn't switch over to the emergency OPS supply. After the final EVA of a given flight, the crew repressurized the cabin, organized all of the things they were going to throw away that hadn't yet been tossed out onto the surface, putting the smaller items in jett bags. Then they depressurized the cabin one final time, with their suits connected to the LM's suit circuit for oxygen and cooling water. Those hoses were long enough to let the crew open the front hatch and toss all the final stuff they were leaving out the door, including the PLSSes. The OPSes were kept for a possible EVA if the docking system failed after rendezvous, and were only used on the J-mission trans-Earth EVAs.

[@DKiSAerospaceHistory]

I was misinformed then. Sorry about that.

[@getsmarter5412]

Good to know!

[@Rmack137]

I posted the same info before I read your post. However, I have a small correction for you. They probably were wearing the liquid cooling garments under their suits, but they weren't hooked up to anything. The LM didn't have a water-cooling system for the suits.

[@Nghilifa]

Correction: 1.The LM ECS did not provide water cooling for the suits, only the PLSS did. 2. The OPS were never "activated", ever. On teh Trans-Earth EVA's that the CMPs performed, they served as a backup in case if the life support tether failed (it provided 02 and "restraint" in the sense that the Astronaut wouldn't drift away from the CSM). The tether was connected to the ECS (Environmental Control System) of the Command Module Bonus trivia: The CMP's suit did not have water cooling, it relied on the air pumping through it to cool the wearer (The CMP wore what they called a CWG, Constant Wear Garment) which was basically coverall similar to long-johns. The LMP and CDR also wore the same CWG on launch from earth, and during the coast between earth and the moon, and then back to earth again). They didn't need liquid cooling for the CMP, as the Trans-Earth EVA was not strenuous, since the spacecraft had already been designed with handrails and foot-restraints , as a result of the experience they had with Gemini in 1965-66.

[@ComradePhoenix]

I mean, it kind of makes sense to use a diving suit as a primitive space suit. They're supposed to be reasonably gas-tight, and resistant to pressure gradients. The direction of said pressure gradient is likely immaterial for most parts of the suit, and for the parts it is relevant, the magnitude of the difference likely matters more. Similar to how the pressure hull of a submarine would actually be a decent spacecraft if the other submarine parts that relied on water were swapped out, and assuming you could get it up there (good use for an Orion Drive).

With regards to Jules Verne: The question of Lunar habitability is raised in the novell (originally they only wanted to send a dead projectile until a french adventurer voluntered to fly to the moon on a one-way trip, taking along the main character and his fierce opponent for plot reasons. The consesus is, that 1. The moon is likely inhabited by intelligent beings 2. The Lunar Atmosphere - if it exists - is thin, yet likely breathable in the lowlands 3. The Moon would serve well to agriculture, the passangers take along animals, seeds and various tools. In the sequel, while on the trip to the moon, they discover one of the dogs they brought along did not survive the violent launch and the decide to throw it out one of the hatches. They adress the problem of exposing the interior to space, however they manage to open a door and throw out the dog, taking care to let as little air as possible to evacuate out of the capsule. Clearly, Verne didnt really have a comprehention of how quickly pressurized air would leak out into a vacuum. Actually, the astronauts are sent around the moon, because there was an error in calculation. They work out their trajectory and perform a course correction with the thrusters they had planned to use for landing, sending them onto a free-return trajectory, leading to a splashdown in the pacific ocean. At no point is the necessity of a spacesuit even discussed, life support systems were deemed only necessary for the trip in the enclosed capsule.

I understand the point you were trying to make relative to physical exertion for microgravity EVA versus lunar EVA, but I tend to think most astronauts might take exception with the assertion that microgravity requires barely no exertion. I've read many astronauts' accounts of EVA, and they all describe it as incredibly physically taxing since any joint movement is a struggle against the suit's pressurization. Even the simple act of closing the hand to grasp a handhold or tool requires such significant force that astronauts have reported losing fingernails.

I recall an interview in a program with a NASA engineer/flight controller from Apollo. He said he hated EVA's, and if it were up to him, they would never do them. The crew would never leave the safety of the spacecraft, including on the surface of the Moon. He said people argued that remotely-controlled rovers, with cameras and arms for manipulating and collecting samples, or robots doing work outside of the ISS, wouldn't have the dexterity or the flexibility that a human in an EVA suit would have, wouldn't be able to reach locations a human could, and a human on-site would be required. He said that was stupidest argument he ever heard, since anywhere a rover couldn't go, which might be too dangerous to go, he certainly wasn't sending a human in an EVA suit to a place like that! He said he hated watching EVA, and he was shocked that we'd come this far without a death in space as a result of a mishap.
