The Evolution of Space Suit Design
William_Lee writes "According to space.com, it looks like we may finally be on the verge of seeing a long overdue, radical redesign of space suits that will result in much lighter, more maneuverable, custom fitted suits.
Now if we can actually get around to sending someone to Mars..."

Is that set of day glow orange moonboots.
soon, but we shouldn't let that get in the way of fashion. I say we should make a rover catwalk.
Yeah baby, shake that spectrometer, OWWW!
I apologize profusely.
And how long ago was that? The space program has severe atrophy.
Laws are for people with no friends.

Do you like your quasi-futuristic clothes Mr. Powers? I designed them myself.
A redesigned suit? How about before they do that they come and fix my toaster. It's been shooting toast at me for years because NASA reprogrammed it for 'defense from hungry aliens' If they can't fix my damn toaster, what makes them think a redesign will help?
Bite me. Seriously, I enjoy it.
I was actually just watching an IMAX Nasa special the other day and was shocked to hear that the current space suits weigh in at almost 250lbs!! I know that without gravity, it doesn't matter how much you weigh, but the bulk in those suits seriously made it hard for the astronauts to do their job at times.
A new "second skin" version of the suit would certainly make it easier on the astronauts, and would free up a ton of space for hauling more cargo up there as well.
On a side note, Nasa was testing this cool 100ft solar array in the movie, which when folded up fit into a 7 inch tall box! It was pretty cool.
Tight-fitting suits may mean that astronauts are more likely to get turned on, resulting in all kinds of mayham and soap operas. Space can get lonely. Maybe the baggy look is better afterall.

Yes, with Lord Bush's leadership, we can finally bring Democracy(c) to Mars!
This article contains material on spacesuit evolution. Evolution is a theory, not a fact, regarding the origin of spacesuits. This material should be approached with an open mind, studied carefully and critically considered.
A thin layer of biomaterial may be sufficient for protecting you from the vacuum of space if they get around the engineering considerations, but I for one would not want a "second skin" as my only protection from radiation and cosmic rays.
This is a consideration particularly where there is no atmosphere absorbing any of it before it gets to you (eg the moon and Earth orbit). The Earth also has its magnetic field helping shield us.
Also consider that the thinnner and lighter a material is the more likely a rip becomes. That one rip will easily end your life. You'd need to incorporate a system self repair of small holes and tears - perhaps a gluey substance that seals under pressure.

Is it just me... or do the old suits look freakin' cool and the new ones look totally gay?
The old ones look functional, with color-coded hose hook-ups and all... like a deep-sea diver... a deep-space diver, if you will.
These new ones... jeez... you can tell if the guy's circumcised or not! Seeing as how an astronaut is probably more likely to encounter an alien being than the rest of us land-lubbers, I'd be very concerned if the first human the martians meet is dressed like a metrosexual.
Sure we do. It's only a couple days away; the technical problems for that sort of mission (which aren't too much greater than those for going to LEO) have already been dealt with. Sure, we no longer have any Saturn Vs, but we could build a rocket better and cheaper since we've done it before. Or, we could try to push the envelope (what NASA has been attempting to do for the past couple decades - unfortunately, without too much luck on complete systems, just lots of individual component successes) to try and advance launch tech to get costs seriously lower.
Mars, on the other hand, is months away, which poses far bigger problems. We'll solve them eventually, of course, but it is a significantly bigger deal.
People said I was dumb, but I proved them.
Just because he announced a plan doesn't mean anything. NASA isn't getting the funding(it needs massive increasesm not cutbacks) to actually DO any of the things talked about.
Maybe his plan is to send humans to Mars first, then to anger the Gua'uld to give humanity a common enemy....

There thing that would stop me from going into space in a new or old suit it small, but important (to me).
What if I get an itchy nose?
I know it sounds silly, but I'm serious. I can imagine getting a serious, claustrophobic panic attack in one of those things, of something as minor as that. Being trapped in this thing and unable to take it off.

When somebody is talking so high on Bush it seems it's ment to be ironic. But I'm not sure on this one.
Dyslexics have more fnu.
If you read official NASA stuff, you will find that the space suits are there to keep the guys warm in the cold of space. That is total BS. Put a self warming thing in a perfect insulator and what happens? It gets hot. It turns out that since the Russians haven't figured out how to make peltier effect space suits, that many of the details of the Apollo era suits are still secret. Even some of the details of early astronaut almost dying from dehydrating in their suits haven't been released
One of the other things is that your blood will boil or explode in space. Thats not true either. All thats needed to protect the skin is a thin layer of something like a cheap wet suit. There have been studies that show thick rubber gloves would work fine for the pressure if there was a way to get rid of the sweat.
The real mechanical problem is keeping the head protected along with proper containment of everything the body is trying to get rid of.
Of course the real problem is all that radiation.
it may be incredibly heavy by earth measure, but the suit also includes a personalized liquid cooling system, thermal protection for the extreme temperature differences between sun and shade, and a pretty serious amount of puncture protection. While it may not fit the bill for hiking across the mars terrain, it does offer some serious advantages over what sounds like an incredibly complex and complicated applied second skin. having worn one (attended space camp far too many years ago), i'd have to say that i much prefer it to a wet suit.
When did George Bush start posting to Slashdot?
Solve the problem of bone rot and muscular atrophy then work on creating vehicles to move people to LaGrange points or beyond.
Ahhh yes... we're one step closer to getting Power Ranger suits. Then we all have to learn to talk and nod our heads at the same time.
Live forever, or die trying.
Thanks to the strong leadership of President Bush, we have a real plan for space, as opposed to mostly circling around Earth currently.
Unfortunately, because it's been announced by President Bush, many people who oppose his other policies (for good reason) will also tend to oppose his space policy, even if they would support it if it were proposed by somebody else.

Strong government investment in space flight won't return unless:
-Private space flight becomes much larger
OR
-China continues to significantly expand its plan for space exploration and manages to put several men on the moon themselves in the coming years.
(More than 30 years ago, Larry Niven proposed such spacesuits in his "Known Space" novels).
Yeah: like cutting Hubble. And racking up record defecits while privately funded firms remind us what the excitement of space exploration used to be all about.
If Bush really wanted to show some leadership, he'd splash ISS, scrap the Shuttle, and set some realistic short-term goals that his administration would actually have to pay for.
NASA *is* doing great work with its robotic programs. But most of those programs were green-lighted when President W was still back in Texas making his bones by polluting his state and signing 152 death warrants.

That's a real problem, but current space ships offer little protection, much less current 250lb+ space suits. No suit is really going to help you, so you need a shelter. Some ideas are lithium shields and crew quarters inside fuel tanks!
These suits are being designed mostly for places like mars which has a partial pressure. They offer protection against dust, which would foul up current joints.

burns210 is saying that all he is doing is asking for the money, as your quotes point out ("seeks", "proposed". He/NASA hasn't gotten it yet or done anything written in stone. As far as we know, its something that he plans to sacrifice and then blame it on Congress.
(He has alot in this budget. To me, it seems like he wants to sell the economic future so he can end up looking better in 4 years.)

86 billion over the next 5 years. Their budget is an average of around 17 billion per year.
Oh, and meanwhile, the current cost of the Iraq war, ignoring debt interest, collateral costs (like the cost of society for guardsmen to be called up or the cost to society of having the wounded for the rest of their lives), etc, is 152 billion dollars, and the US just announced we'll be keeping high troop levels for a minimum of two more years (likely many more unless they cut and run). Just showing a budgetary priority comparison here.

Drill baby drill - on Mars
True. He is 'seeking' but has not gotten yet. I do give Bush some credit for that, but it hasn't gotten to the engineers yet.
And your second quote, Bush is proposing cutting 11 billion dollars from NASA's other projects... NASA is doing many cool things on many fronts. Cutting costs in other departments or projects is harmful. It needs to be a $12 billion increase in the budget, for several consecutive years, not a $1 billion dollar increase(they get something like 15-20 billion annualy as-is) and pulling 1/2 theird budget from other projects to meet Bush's goal.
What was the phrase: "Faster, Strong, Cheaper: Pick any TWO that you want."
NASA needs all 3, and it needs the resources (money+time) to get there. It needs the funding to build and design a more modular and reliable/reusable space craft. It needs funding for new space suits, satelites, probes, robotics, infrastructure upgrades, IT upgrades, planning/testing phases, etc.
We weren't going to use the Shuttle in the first place.
What Bush has done is decimate the scientific programs of NASA and had the agency over to the aerospace lobby. But with comments like...
"mostly circling around Earth"
you have made your impression of science apparent
Did you know that the "science of the outer planets" scientific research line for 2005
Was just cut? Yup, wiped off the board. This was a small program, only a few million, and it funded some very interesting work... Well, it's gone now, I guess that makes you feel very patriotic...

I'm not sure if I agree with their approach. I would think that loose fitting, light, super high strength baggy outfits would be the best way to go. They could be weaved in with netted fibre, like a hot air baloon. As long as they have enough pressure to maintain proper-psi on the skin, it doesn't matter if they're a little loose. or if they puff out a little. Shoes could be regular tennies worn on the outside of the suit, maybe something similar with leather gloves. Humidity, temperature, and varying air pressure would half to be managed (maybe a high humidity zone for breathing, and a low humidity zone for sweating). A portable (roll along?) unit hooked up to a long tube would be eaiser to work with. If a problem happens, the could just disconnect the tube, walk back to the unit, and plug in there, take a spare along too. For radiation, there could be carry along umbrellas, or shelters. Maybe light protection in the suit, but not to weigh it down.
IMHO, The idea of laser custom fit suits, and spraid on super-skin just seems like problems waiting to happen. It's better to keep it simple to use, simple to change, repair, simple to manage, and inherently uncomplicated.
Doubt it, cost is too high with few benefits unless they go for a moon base. And by benefits I don't just mean scientific and economic but also political/social. I doubt China wants to mimic the US space program since that doesn't boost morale, however expanding on it would. However, a moon base is a very costly endeavor and China may simply not be willing to spend that much for the potentially limited gains.
I pity the first crew on a mars mission... radiation sickness is a horrible way to die... in a tin coffin millions of miles away from home with nothing but the coldness of space arounb you no less...
What a disappointment. I thought it would be something like this.
NASA announced today its plan to recruit exclusively from the U.S. bobsled and luge teams.

Incorporated into that second skin would be electrically actuated artificial muscle fibers to enhance human strength and stamina.
Right - this technology is WAY far away. Synthetic muscle fibers have been under development for the last decade. One of the first innovations were Contractle Polymers. These have since given way to other technologies - but non yet equal the strength of human muscle. In addition to make them more useful, these fibers are going to have to be multiples of the strength of human muscle. Also, the notion of a "spray on" skin that creates a powered exomuscular infrastructure requires a fusing of so many current and future technologies that this is not a particularly realistic goal at this time.
I think what i'm trying to say - this isn't news it's a dream. Obviously people need to figure it out - but there are not going to be tangible results from such research for sometime.
I met Mr. Kittinger in October this last year.
He's the man who jumped from a weather balloon at 102,000 feet wearing a space suit. On the ascent he had a problem with one of the gloves on his pressure suit. He elected not to tell anybody believing that the silk glove he wore underneath as a liner would keep his hand from rupturing. It did in fact keep his hand from rupturing, though it swelled to 3 times its normal size and was useless until the swelling went down.
The point I'm making is that it if the spray-on suit is flexible enough to allow you to bend your elbow, thereby stretching the material on the outside of the bend, could it be strong enough to not only contain the pressure of your body; but contain it with enough pressure to maintain its shape? With all of the potential twists and movements of a normal human body, how would it know what stretching to allow, and which to contain?
Hot Damn! It's the Soggy Bottom Boys!
Don't the Fremen use stillsuits that are just like this?
Is the peacekeeper spacesuits from Farscape.
They're black - instantly cool but probably a problem to spot your mate when his dark face shield is closed - the helmet is just barely bigger than your head - so you don't go knocking your noggin on stuff cause you forgot - and all the fastenings had that appearance of being sturdy and functional without taking ages to fiddle with.
They weren't skin tight, more like about how baggy a tracksuit is on a regular sized person, but they weren't overly bulky either. The costume designers even made sure to put small "life support" systems on the backs of the suits too, and although they only looked big enough to scrub CO2 for maybe 30-45 minutes, I imagine something slightly bigger could be made, or have hook-up points on the suit and ship for extended EVA.
It would have been good to find an interview with Claudia Black or Ben Browder that asked if the general design of the mock-up suits was comfortable.
Skin tight is functional, but I can see personal aesthetics screwing with the crew - we're only human, and things that shouldn't bother us generally do.
His name is Robert Paulsen...
> Yeah: like cutting Hubble.
If I'm not mistaken, isn't the reason they're scrapping the Hubble because it'd be more expensive to repair it than to let it deorbit and send up a new telescope? Besides, didn't it preform above and beyond it's original mission profile?
I say let it go down in dignity and get some new tech up there, instead of letting it languish over the next decade with continual jury-rigged refits.
After travelling recently to 16000 feet with out any pressurization, I would think in my uneducated experience that a space-traveller could get the bends with these new suits. Could someone please explain? I don't have any background that explains this. Do the space-travellers depressurize while in the ship/space-station?
Quit honestly, it would have better had we gone to Mars. It would have cost a fraction of what Iraq has cost. We have already spent about 155B (that is billion, not million) on Iraq and he is asking for 80B more (just for this year). It would have been better for America (but not likely to find oil there, so we do not go).
Human skin is actually a surprisingly strong pressure barrier. The conterpressure suit can be an open weave with up to millimeter sized openings. The biggest problem is figuring out how to keep pressure on the concave areas such as under the arms and behind the knees. An advantage of counterpressure suits is that a tear in the suit doesn't result in catastrophic pressure loss. It only causes injury to the area of the tear. Another problem with them is getting them on and off. It would be like putting super tight pantyhose over your whole body. (not that I know anything about that)

Here are some papers on counterpressure suits:

ooooooKay then. I suppose you'd prefer that everybody in research positions stop using their imaginations and coming up with new ideas?
Seriously- what qualifies this person to question some MIT professors' qualifications to talk about the future of space ANYTHING?
Look, they're doing real research, and if you RTFA (the rest of it), you'd know they're planning on prototyping and making it. Is it guaranteed that they'll use this stuff? No. But none of these people who envisioned nuclear cars, jetpacks, tube elevators, practically sentient computers, and ray guns were promising anything. Except, well, we've got ray guns, practically sentient computers are still possible (the time-frame was just wrong), and cars or planes with quantum nucleonic reactors are feasible.
Hmmmm... turns out, there actually is data on animals (intentionally) and humans (accidentally) exposed to a vacuum.
- You'd lose consciousness after about ten seconds
- Your blood would NOT boil.
- Your body would swell up to about twice its normal volume, but this could be constrained by an elastic body suit.
- You'd want to open your mouth: If you tried to hold your breath, your lungs would balloon up and rupture.
Then there's the interesting case of a balloon ascent to 20 mi (32 km, near vacuum) in which the pilot lost pressurization only in his right glove. His hand swelled and became stiff and painful, but three hours after landing, his hand was back to normal, with no ill effects.Details of all this here

Diplomacy is the art of saying "Nice doggie" until you can find a rock. Will Rogers
Things like this are the perfect target for the Centennial Challenges program, a NASA program of prize contests for private endeavours to create or accomplish things related to space exploration. Spacesuit design is an area where a small private company can make appreciable progress with a reasonable amount of investment.
An even more specific goal is a better astronaut glove. Gloves sound like very simple things, but it's been pretty tricky so far to create a glove which can reliably remain intact in a vacuum while also giving the user a good degree of manual dexterity. A space policy analyst said the following in an article:
In fact, the glove is the biggest problem in designing the high-pressure space suits necessary to avoid the bends (the same problem a diver has when she surfaces too quickly) when an astronaut goes out into the vacuum of space. Larger joints like shoulders and knees have special designs that are zero-volume change, but no one has yet miniaturized such a design to finger joints.
Because this is a critical technology, and one that has great leverage in influencing launch system trades, I would propose the following:
Build a vacuum glove box with a task box inside (perhaps an automobile engine that has to be dissassembled and reassembled). Put up a purse of a million dollars to the first person who can achieve the task working through gloves under a pressure differential of half an atmosphere, without a break.
Unlike many space activities, it's a project that can be literally done in someone's garage, and it may spur a great amount of innovation for very low cost. Accordingly, it would make an excellent candidate for the Office of Exploration's new prize fund, and I hope they'll strongly consider it. At very low cost to the taxpayers, one or more successful concepts could lay to rest myths about the intrinsic difficulty of working in space, opening up the options for how we will get to the planets beyond redoing Apollo, perhaps saving billions in dollars, and constituting a major step toward becoming a truly spacefaring nation.
The spray-on thing may be new, but the idea of a mechanical counter pressure suit isn't.
Jerry Pournelle mentioned a project like this in A Step Farther Out, a collection of science articles related to space travel and other science fiction ideas written in the seventies. He claims that tests of the suit design in actual vacuum conditions were going very well, and then the project got canned for no apparent reason.
I'm glad that it's back in development - I don't think we'd get very far in space relying on clunky armoured suits.
On a side note, it's very amusing how many people have bizarre misconceptions of the effects of vacuum on the human body, thanks to godawful movie "science".
I hate President Bush as much as the next reasonable person, but was this post modded as a Troll just because it acknowledged the fact that Bush proposed a new space plan?
And he increased NASA funding, while most everything else got funding cuts. Was there something else you were expecting?
In any case, I'm of the opinion that cutting the Space Shuttle and ISS from the budget will free up more than enough to get us on the road towards permanent, largely self-sustaining lunar habitats.
The problem is with the policy. Not enough money has been made available to NASA to actually do much.

What's that hissing sound???
First, why is everyone so damn aggresive in their rhetoric on this issue. Chill out and explain your ideas rather than lashing out.
"You're a Hollywood-trained idiot. Your blood will not boil. Your body will not explode. There will be outgassing, but not so much as you think, and that's not the same thing as *boiling*, anyway"
This is not correct. If you went into the vacuum of space you would start to blead out of your nose (vessels very close to the skin surface) first then your eardrumms would pop and you would blead out of your ears. Meanwhile your skin would be hemoraging all over your body, you would swell up like a balloon (ever been on a long airplain ride and taken off your shoes?) and you would pass out from lack of blood supply to your brain. The blood streaming out of your nose and ears would most certainly "boil" as there is no pressure to keep it in liquid form. PV=nRT. With the pressure going to zero the volume must increase, creating a very large diffuse quantity e.g. a gas. Call it outgasing or boiling, but liquid blood will leak out of your body and becomes a gas.
Yahh skin tight vac suits that rely on mechanical pressure to augment your skins pressure holding ability - new and exciting technology. I remember how exciting it was to read about...in 1968, when it was first discussed.
There is no God, and Dirac is his prophet.
Unfortunately, we in the aerospace industry no longer believe a president when they outline such a plan -- as nearly every president has done since Nixon. But (with apologies to Tom Wolfe), no bucks, no Buck Rogers.

At least they are looking at it again.
On a slightly different topic: The pictures are very interesting. But, there is a problem in that *all* the holes in the human body have to be covered. So, the pictures showing a helmet over the head and a nice smooth body everywhere else are a bit misleading. At the very least you need a "helmet" that cover the anus and urogenital region. So, you wind up with a hard helmet around the head and a hard diaper around the pelvis. At the very least you wind up with a kind of back to front cod piece.
Seriously, the pictures from NASA allways portray the astronauts as being built like Barbie and Ken.
