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."

is Margaret Thatcher modelling it?
for any metrosexual astronaut.
I'm going to have alot trouble hiding my giant boner as I check out the female astrounaut corps.
Kinda reminds me of the suits from Star Trek TOS - sans the goofy helmet and the nameplate - or of something from Power Rangers...
StarTrekPhase2 - The Five Year Mission Continues!
They're waiting for you, Gordon. In the Test Chamber.
Is it just me, or does this sound like something out of Sci-Fi? Sleek, skintight, spacesuits? Anyway... Finally! A redesign of the spacesuits. This has been coming for a while, and most people probably should have forseen a new design. What amazes me is how futuristic and sci-fi this sounds... or is it just progress? What ever the case, this is real progress and innovation.
All these skintight spacesuits on attractive women in science fiction movies are finally reality!
I think we can keep recursing like this until someone returns 1
Masses 300lbs, weighs nothing, but still no friend of mobility.
Don't blame me, I voted for Baltar.
These suits were described in Red Mars, Green Mars, Blue Mars - called walkers in those books.
Too bad it won't fit the Sci-Fi chicks with three boobs.
The next thing they have to make is a chain metal bikini that can give Elven Warrior Maidens the protection from dragon fire they need.
Hopefully I didn't put any [] around my words.
Mmm mmm.... what? Dave Newman? blarghghgh NOOO!
Oh. DavA Newman... whew!

What more could a nerd ask for. I mean really, she designs
space suits.
One, how are they going to keep the astronaut warm/cool in it.
Two, they talk about how its safer if it gets punctured because the hole can just be patched without affecting the rest of the suit. 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.

The price is always right if someone else is paying.
If I remember correctly, previous studies into this kind of suits had problems getting a tight fit (needed for counterpressure) on concave parts of the body - e.g. armpits, etc. If any of the members of the team happen to be lurking, could you fill us in on how those are being addressed?
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?

Welcome to a world where the Fantastic Four get science right. Nooooooooooooo!
One of the interesting space startups at the moment is Orbital Outfitters, a company supplying space suits for the NewSpace community. Go sell them this technology so they can actually test it.
How we know is more important than what we know.
Masses 300lbs, weighs nothing, but still no friend of mobility.
This is utterly wrong, not insightful. Pounds is a measure of weight, which is the measure of the force of gravity upon an object's mass.
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.

You can exert mechanical pressure but the real air pressure inside the suit is going to be zero. That means water is going to boil off. Presumably they have considered that issue.
If the suit is skintight, then we should see a lot more of the Female Astronaut Program. All of it!
Of course, this development will open the way for space fashion. Designers will now be able to dress up the outside of astronauts, without it looking like a 1950s monster movie. Superfluous garments that don't constrain us will now be possible, and we'll start competing with them out on the space cameras.
It'll finally look a lot more like the SF movies that have inspired most of us to care about humans in space. Now all we'll need is those neat little hoops at the ends of their arms and legs. And a talking robot.

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

The idea of using mechanical pressure instead of air pressure is not new; quite aside from the fantasies of SF writers through the years there have been serious attempts to make 'spandex spacesuits' before.
Major problems I've heard of include joint mobility (imagine a tight spandex sleeve - now imagine flexing your arm at the elbow against the resistance of the material) and the sheer unbelievability of the idea for most people. Of course, most of us would look like crap in a tight spandex bodystocking anyway.
Thermal and radiation protection could be handled much as they are now except that it wouldn't be tied to the pressure vessel aspects of the suit. Imagine rather chunky overalls, for example. I suppose the good news is that the outer parts would then be much more universal, making them easier to manufacture and maintain. You could even store them outside the rather cramped airlock and put them on outside in, say, the shuttle bay.
they must still use a normal life support system for the head, as you can't wrap anything over the astronauts head. i wonder how this would cope with a rip in the fabric to, you might have your flesh ripped from your bones and out the hole in the suit?
If you mod me down, I will become more powerful than you can imagine....
Kudos to the fine folks at MIT, but again, they have done nothing new.
The first human in space was piloting an X-15 while the rocket program was still producing some rather impressive fireworks displays.
An undeservedly underrated movie, it had skin-tight (and sexxxy) spacesuits much like that pictured in TFA

I bet the Chinese are happy. Because after all, the US can barely keep its space shuttle flying, while the Chinese are planning a manned moon mission. They need these suits a lot more.
/sarcasm
Yes, call me a troll. After all, US foreign policy has done so much for world peace in the past few years. Those billions were well spent, boys.

Men and women will travel on vacations through space, go on space walks with suits that are skin tight, strong, and feel like they are not even there. Colonize mars and beyond.
Not sit on earth as it is turned into a nightmare that last forever because of nanotech keeping you alive while you are beat and raped until the end of time by the one you tried to break.
Where is the bathroom?
With a gas-pressurized suit, you put it on at atmospheric pressure and pump it up as you go outside. These squeezy suits are surely going to *hurt* if you wear them in a normal atmospheric pressure environment, and I dont see a way of ramping up the squeeze factor. Oh well, maybe they've got that in there somewhere, I just dont see it.
I'm thinking this has some inherent drawbacks. With gas pressure regulation, the pressure inside the suite is the same regardless of whether you are inside the space capsule (at 16psi ambient pressure) or outside (at zero PSI ambient). 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. That's going to raise your blood pressure. Not by enough to be harmful, (after all scuba divers have the same). But more importantly, if you take our helmet off now you suffocate inside the space capusle. You suffocate first because you cannot physcally open your lungs with 32 PSI pressing on them in a 16psi atmosphere. 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. And finally, if you took your kemet off then you have the extra 16 psi in your bloodstream pushing against the back of your eye-balls.
I wonder how they dealt with that?
One speculation might be that they made the suit not stretchy but just a fixed size that EXACTLY fits you. This way you have no pressure until you expand into the suit which then applies a counter force.
However I cant' see that actually being possible, and having any flexibility. If You expand even slightly your blood pressure will drop. it would have to fit everywhere exactly, down to the gonads. cause you'd get enormous swelling in any place there was no counter-force.
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? Sure you could have the person breath through a regulator. But the face itself would not have pressure on it.
Obviously I don't understand how this thing works or can work.
Some drink at the fountain of knowledge. Others just gargle.

Traveler from GDW made a big point about space suits being skin tight at higher tech levels, so that users would not be encumbered, just sort of popped in my head when reading the headline.
Same principle was used on Mars in Heinlein's Red Planet.

I mean, seriously, who at MIT is paying Slashdot for all these ads? It's like suddenly MIT is the new Google or Apple or Nintendo.
That said, imagine the computational power of a beowulf of MITs! If they cured fear and invented a new spacesuit in one day, imagine all the other crazy stuff they could come up with! Even better, if MIT can run Linux, then... wait, I guess most of MIT does already.
I must be new here.
I thought most of the problems are because the spacesuit needs to insulate against the heat and cold, and protect from radiation?
"Feels like I'm wearing nothing at all... Nothing at all... Nothing at all..."
Love many, trust a few, do harm to none.
Heat especially is actually easier since human skin has built-in evaporative cooling. Can't beat vacuum for insulation. Most of the heating/cooling problems of current suits are self-inflicted by their bulky closed designs.
Radiation? Nothing shorter than UV is going to be stopped by a suit anyway and UV can be blocked by that beautiful silver film.

I remember in the 1960 the U.S. Air Force and Navy were testing pressure suits to work in the high performance jet fighters at that time and I remember those "disco" suits that they developed there were skin-tight and very uncomfortable. However for 40 years later I believe that materials have advanced enough for snug fit pressure suits that uses both air pressure and mechanical pressure to create a good pressure suit that will be easy to work in and have long duration that astronauts need. The current two EVA (Extra Vehicular Activity) suits that the Russians and Americans use are a compromise between many things like duration in EVA, pre-breath before use, dexterity of the suit so hopefully this will solve all of this.
I believe the book was "A Mote in God's Eye", where I first saw this concept explored.
It also seemed to be one of the more hard science fiction books -- for instance, though there was faster-than-light travel between systems, travel within a system was still sublight, and without any sort of artificial gravity or "inertial dampening" -- if you want gravity, you accelerate, and there are couches to let you accelerate faster (3g or so), but when you're not moving, everything's weightless.
(Getting even more offtopic, I wonder if Firefly might've worked just as well without artificial gravity. It'd be difficult to do, though.)

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.

He's right. Applying pressure to the body is only one part of the problem. This suit won't address the other problems and has some of its own. The idea also isn't revolutionary. NASA has considered skin-tight mechanical-pressure suits for years. This is only one such iteration.
I won't put one of these on without a radiation-proof 'nad shield.
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.

Finally a reason to send Jessica Alba into space...
Can you? Wouldn't you just land with whatever force you applied at the beginning of the jump? On Earth, I can jump a certain height unloaded and a lesser height while carrying a backpack full of rocks. I'll have farther to fall from the higher jump, but I'll have more mass getting attracted by gravity on the shorter jump. I think they would cancel each other out.
Or, actually, there might be less force during the unloaded jump. When loaded I will achieve a lower velocity than when unloaded. Therefore I will have more time to push against the ground and put more energy into my jump.
If you do, then, sure, you can optimize the heck to meet your goals, at the expense of everything else. Whopee ding.
But in the real world, astronauts will be happy to trade off style for function. Especially life-saving functions.
These spandex suits may look keen, but you've traded away:
The suit has to supply enough mechanical pressure to keep it from puffing out in response to the pneumatic pressure inside the suit.
I am the one true god. However, as an atheist, I don't believe in myself. I guess I have a self-esteem problem.
Stupid sexy Flanders!
They're still going to be making next generation space suits out of cloth? The hell with that! Give me the energy skinsuits from Dan Simmon's Hyperion books. While we're at it, I wouldn't mind a pair of Ouster angel wings, a FORCE assault rifle, and Hawking-Drive equipped starship.
One pound-mass is the mass that would experience a force of one pound-force in a gravitational field of 1g.
Regarding jumping on the moon, conservation of energy dictates that your landing velocity will be the same as your liftoff velocity (baring any change in starting/final elevation like jumping off a cliff). You can only land hard enough to hurt yourself if you jump hard enough to hurt yourself...err, well I guess that's not quite right. Some people are just clumsy.
In that novel, one of groups involved had developed a "space suit" that was actually a force field that not only held in air, it was highly reflective (makes a great camo suit) and would actually stop bullets (with the side effect that the energy of the impact was dissipated by the field - with the "wearer" inside...).
Pretty cool idea.
This looks a lot like the space activity suit from the sixties. In fact, there's an edit in the wikipedia entry from january 2005 noting that the MIT is doing research that would lead to the suit we are seeing today.
Check the papers at the end of the wikipedia article, too.

neoprene.
On a microscopic scale skin has no problem being exposed to vacuum for short periods of time (hours). The purpose of the suit is to hold back moderate pressures on a scale of greater than about a millimeter, so that air pressure doesn't explode your chest, so that blood an other body fluids don't boil, and so that blisters don't form from fluids trying to escape the body's fluid-tight skin.

Human skin actually does a very good job of selective permeability; osmotic pressures across it easily exceed an atmosphere. All it really needs is mechanical support to prevent the Mother of All Hickeys.
So, no, it wasn't a joke. Nice that you can't tell which of my posts are serious though. I think. Maybe.

That was a funny show. The SSA was hilariously incompetent at times.

The suit's pressure takes care of that. Everyone's dick looks the same, a paper thin wrap around your entire torso.
Humping will be easier too, or more, umm, fullfilling. Less grapplifying but more gratifying. And using the vacuu-toilet might be easier, too.
Anyway, I suppose these suits will make it easy to pass each other in tubular corridors during times a newly implemented "readiness condition" could be useful. Imagine the conditions they have now: either the protective gear is worn or not worn. Now, imagine needing to grab only the helmet and a mini bottle of air....

This story was carried in PopSci a few years ago. It looks as though they have made little progress. I imagine they are trying to stir up publicity to get some more funding. P.S. Every 300lb suit you carry to space means 300lbs less cargo/supplies you get to take. At >$10,000 a kilo, cutting a hundred or two pounds is a big deal (especially for numerous suits).
It's sex appeal.
Remember, we could be sending robots everywhere for the price of this. Science is not what NASA cares about. NASA cares about their budget. Going to Mars sells well. Going to Mars in skin-tight suits sells better.
Wow!!! looks kinda like the "Normal Suit" space suit in Mobile Suit Gundam. Heck its almost the correct color scheme for some of the series. Seila Mas Kaki next maybe?
Please allow Jeri Ryan to become an astronaut. She looks good in something skintight.

I remember reading about this idea a long time ago, perhaps even in Analog magazine. Because the skin is gas tight, all you need is a suit to provide the counter pressure to prevent blowouts. So the idea is finally being tried out.

History:
Original research was done by Paul Webb, who in 1968 published a paper titled "The Space Activity Suit: An Elastic Leotard for Extravehicular Activity" in the April 1968 issue of Aerospace Medicine. Research was funded by NASA.
NASA warming up 40 year old ideas and praising themselves is so lame...
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.
Wrong, it's a well known fact that you can't operate that diaphram at more than a few pounds of pressure differential. The classic example of this is that you cannot breath air in through a tube from the surface when on the bottom of a pool. Essentiall every school kid has been taught this by grade 10.
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.
Wrong. THere's a 16 pound difference you can't over come with your lungs. See above answer.
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.
wrong. It's ridiculously well know it's impossible to breath under such strain.
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.
Wrong. basic chemistry at work. the energetic cost for a cell to break a covelently bound CO and transfer it to the blood will be higher if the blood is pressurized. Likewise the energetic cost of transfering gas o2 into the pressurized blood will be higher when the blood is pressurized higher.
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. You are correct that you don't see the problem. This however simply means you don't see the problem. It's there, so look harder. (how do you seal the bubble without crushing your neck, for example.)
Maybe since they're having so much trouble with the stretchy joints, they could use the properties of carbon nanotubes as mentioned in another slashdot article from today to their advantage.

If we can form fit it to ourselves, then we can form fit it to animals as well. Imagine training a dog or chimpanzee wearing one of these suits to fetch tools, packages, etc. on the moon or Mars.

First you claim that higher pressures do affect the solvency of the gas and then you claim they don't matter because of osmotic gradients. Pick one please. Free energy is free energy and that's what drives chemistry And this rubbish about osmotic gradients is silly and inconsistent restatement of that. If you pressurize something you affect the solvency.
And the question was, how does it work when there's these fundamental issues that are hard to see how it overcomes? not "see it must work there's a model in a mock up". No one is even denying it might be possible. It's just hard to see how.
