    Nice. Hopefully we’ll also learn more about how they’re testing these things.

  • Terry Stetler

    However NASA wants to test them since they’re judging on, and paying for, the suit milestones.

    SpaceX’ers on r/SpaceX report the suit looks cool, and would be at home in Ender’s Game.

    I wonder if Newman’s biosuit figures into this.

  • duheagle

    Like this?

  • windbourne

    that is like newman’s biosuits

  • duheagle

    I think Newman’s biosuits fit a lot tighter than that.

  • therealdmt

    I wish it would, but I doubt it. I have no information one way or the other though, so hopefully! We know Elon has placed an emphasis on looks…

    Personally, I’ve been interested in seeing a skintight pressure suit come to fruition ever since I first read about them in a Jerry Pournelle novel way back in the 70s or early 80s.

    Regarding Dave Newman, she might have gotten put in as deputy administrator a bit too late in Obama’s term to have much of an effect. Her length of service as Deputy Admininstrator was less than 2 years (20 months plus a few days) and really more like 1 1/2 years considering everyone knew there would be a change in leadership after Trump won the election in early November (so, she was a lame duck the last approx. 3 months of the 20 months she served). I never heard about NASA making any big skintight suit awards in that time, though I certainly may have missed some developments

    Reading more about such suits here ( http://www.projectrho.com/public_html/rocket/spacesuits.php ) just now though, it seems there may be a few unattractive issues:

    “They do need some care in design, though. Any concave areas on the body that the suit does not hug will bulge out under internal body pressure until it fills the void (i.e., your armpits will become armhills). Putty or fluid filled bladders will be needed to prevent this. Care must be taken around those nether regions, the small of the back, and in certain locations of the female chest. Male wearers will need a rather sophisticated cup to cover the genitals. Even with the cup, the suit will tend to grab male wearers uncomfortably in the crotch.

    And upon entering vacuum, one will have an instant attack of dire flatulence (aka High-altitude flatus expulsion or HAFE). Don’t be polite, let it out right away or you may damage your intestines.”

    Eww.

    “Flat chested lady, must like farting” would seem to be part of the requirements description for future astronaut applicants

  • windbourne

    It is not the fact that they are skintight, but should require less pressure, air, etc in those suits. In addition, I would think that these have more insulation and less energy needed for cooling. Finally, being skintight, I think would make them less susceptible to cuts, and when cut, easier to patch.

    Basically, I think, that with proper pick of materials, that Newman’s approach is superior to the standard suits.

  • windbourne

    BTW, knowing musk, he did go for skintight, but just as much for aesthetics, as practicality.

  • therealdmt

    I’d like to see that Newman biosuit get developed too

  • Jeff2Space

    The flatulence part happens with any low pressure suit, which is pretty much every single (pure oxygen atmosphere) EVA suit ever made.

    Elon shared the first pic today — it actually does look kinda like the Ender’s game suits! Also, I found some leaked images online that disclose the whole suit. I’m not gonna post them as it doesn’t seem right, but when you see the whole thing, it looks kinda like a white motocross suit. I guess that’s just the cover — maybe it’s a skin tight mechanical pressure suit underneath? Otherwise, I can’t see how it holds pressure. Anyways, it’s not all that dissimilar to this: https://uploads.disquscdn.com/images/225acec8f4c195dfef035698f1d5cf1f3b750bbe2e0d1be28294667e8bf8036f.jpg

    Or maybe more https://uploads.disquscdn.com/images/4b95d08332f72cbdfae1af95937d2136ffab680934bb6efb96a64336dabafe02.jpg this (the one above is too baggy looking):

    Elon: “First picture of SpaceX spacesuit. More in days to follow. Worth noting that this actually works (not a mockup). Already tested to double vacuum pressure. Was incredibly hard to balance esthetics and function. Easy to do either separately.”

  • windbourne

    Hopefully the air is scrubbed quickly. Of course, the good news is no chance of being blamed for somebody else’s 🙂 ( I have young boys ).

    Wonder why entering vacuum does that? I would assume that lowering suit pressure would be the issue.

  • windbourne

    Interesting read.
    I wonder if softsuit can start higher pressure and mixed and then move to pure o2 and lower pressure?

    That might help rid the bends.

  • windbourne

    They do. Very little air under biosuit. Strikes me as ideal way to go. IOW, mechanical pressure on skin, and less air exposure. Should be able to add to extra liners with that. 1 that seals the out side for nicks and cuts, but I would wonder if possible to have a coagulatent layer to help stop any bleeding quickly.
    Likewise, it would be interesting to have a bladder below neck that can allow helmet to have a couple of more psi above suit with mixed air, and then drop pressure over an hour or two, while enriching helmet mixture.
