MIT Team Designs a New, Sleek, Skintight Spacesuit

iamdrscience writes "MIT aeronautics professor Dava Newman has designed a new spacesuit along with her colleague, Jeff Hoffman and a group of students. This is far sleeker and lighter weight than the suits used by astronauts today, promising greater mobility than the traditional bulky suits of today which can weigh 300lbs or more. Instead of gas pressurization, the new prototype BioSuit employs "mechanical counter-pressure" in the form of skin-tight layers wrapped around the body."

    One, how are they going to keep the astronaut warm/cool in it.

How are you going to puncture it in a way that doesn't puncture, you know... you? Even if the suit doesn't depressurize, it can't be good for your cardiovascular system to have a gaping wound exposed to vacuum or micropressures.

    Somebody who does this for a living will have to back me up (or shut me up), but isn't pounds (as in lbs.) a measurement of weight, as in the English-system unit of mass times the earth's gravitational acceleration, unlike the metric unit, grams, which is strictly-speakly a measurement of mass-only (as in free of gravitational acceleration)?

      And on that note, how is having 300 lbs (or mass-equivalent) less gear going to keep you from hopping off the moon into outerspace forever? Didn't the extra mass come in handy to keep people from flying away? Actually, the new space suit makes astronauts look sexier, thereby causing the moon to be more attracted to them. This increased attraction makes it less likely they will fly away. Of course, it also means they have to change back into the clunky old fashioned space suits when they want to take off, in order to decrease the Moon's attraction enough to let them go. It also means that the Moon may call them several times a day to try to get them to come back, and may occasionally drift closer to the Earth to get a better look at them, despite the restraining order barring the Moon from getting within 230,000 miles.

      Sure, this seems like a good idea, but it's really not cool to play around with the Moon's emotions like that. No one has visited it in 35 years, and it is getting pretty desperate for attention.

      but isn't pounds (as in lbs.) a measurement of weight

      According to Wikipedia, "pounds" originally and still may refer to force (weight). However the "pound avoirdupois", avoirdupois being the system used in the United States, is defined to be a measure of mass.

      And on that note, how is having 300 lbs (or mass-equivalent) less gear going to keep you from hopping off the moon into outerspace forever? Didn't the extra mass come in handy to keep people from flying away?

      Escape velocity from the moon is 2.4 km/s. I don't think that merely weighing 1/6th as much as you do on earth would allow you to launch yourself at that speed. The astronauts would be able to leap even farther than they could in the bulky spacesuits, though.

    A book called The Millennial project was released several years ago that describes skin-tight space suits in very clear and specific terms, dicussing how a tight material is sufficient to handle the pressure, and how just a chest plate might be useful to provide radiation protection and protection from micrometeors and the like. I believe it described the use of tungsten..

    It's a really interesting book, talks about a lot of other technology, and seems pretty darn reasonable about most of it too.

    Back when John Campbell was editor of Analog, one of the "Science Fact" articles proposed that spacesuits could be made of gas-permeable mesh that would let skin do what skin does: selective permeability. (Obviously, some parts such as the head still get air!) Provide pressure support but don't try to create an interior environment, and you eliminate a huge number of the worst design challenges of a spacesuit.

    You also make it a lot less vulnerable to life-threatening damage.

    Chalk up another one for the old Analog, right along with Giant Meteor Impact.

    To be worn in space, the BioSuit must deliver close to one-third the pressure exerted by Earth's atmosphere, or about 30 kPa (kilopascals). The current prototype suit exerts about 20 KPa consistently, and the researchers have gotten new models up to 25 to 30 KPa. This isn't just a proof-of-concept, this is a real prototype under testing.

    Particularly since coagulation requires the presence of air in order to occur. Your wound wouldn't clot.


    No, it does NOT.
    If it was the case, you would die from internal bleeding at the slightest shock that would burst the smallest blood vessel.

    Contact to air is only 1 of the huge amount of conditions that can trigger cloting.
    Pretty much anything that isn't healthy un-wounded endothelium (the thing that covers the walls inside of blood vessels) can trigger clotting (thus the problems that can be encountered with prosthetic cardiac valves, or people who have damaged blood vessel walls because of way too much high cholesterol, or additive that are put inside glass container for blood sample handling).
    Bleeding in water is the only case where you don't clot easily. Not because water has some magical properties that prevents clotting, but just because the coagulation factors that are needed for clotting get diluted in the water.

    Back to the case, TFA mentions that bandage should be applied over the suit breach. Some pro-coagulant substance coating the middle of the bandage, where it goes over the hole, should help make sure the wound clots well.

    Obviously I don't understand how this thing works or can work.

    I think it's just that you don't understand how lungs work.

    When you inhale you don't inflate your lungs by increasing their volume, like opening a bellows.

    The way you inhale is by lowering the pressure in your chest cavity by means of the diaphragm, which contracts downwards, increasing chest volume. As the pressure in your chest (outside your lungs) decreases, air forces itself into your lungs and inflates them.

    It seems to me that if this thing is mechanically applying 16 PSI in vacuum then it must apply 32 PSI when inside the capsule.

    Yeah, but there's air inside your body pushing out, too, remember. That's what the 16 PSI is there for, in fact - to restrain the gases within your body. That's why the suit has to be pressurized - to push back on the pressures within your body that, normally, the atmosphere will push back against.

    So, inside the capsule, you're facing 32 Psi minus the 16 psi pushing out from inside you, so you're only against the 16 psi tension of the suit. I imagine it's like breathing with an ace bandage (or, like, a bra) around your chest - more difficult but certainly not impossible.

    And secondly even if you solved that, then you still have the problem of the 32 psi pressure making it harder to dissolve gas in your blood, so your cells cant get air or release CO2.

    Higher PSI makes it easier, not harder, to dissolve gases in fluids.

    Finally, I can't see how this works around your head. If the suit is not pressurized then how do you maintain 16psi pressure on the face?

    Big bubble helmet pressurized to 16 psi, like always. I don't see the problem.

    Well, ignoring for now that atmospheric pressure is 14.7 psi, not 16 psi - there's no need for the suit or the occupant to actually be at sea level atmospheric pressure. In fact, it may be undesirable, as it means you need more powerful life support systems - more weight, more complexity.

    The human body is fine at 0.2 atmospheres so long as it's getting enough oxygen. While in the spacecraft without a helmet, with 0.2 atm (less than 4 psi) being pressed against your chest might be uncomfortable, it's not going to kill you.
