>Spacesuits have come a long way since the 1960s. But they're still bulky spacewear, if you will, limiting the astronaut's range of movement. But, MIT researchers are working on a “second skin” spacesuit that is flexible, lightweight, and lined with “tiny, muscle-like coils.”

>“With conventional spacesuits, you’re essentially in a balloon of gas that’s providing you with the necessary one-third of an atmosphere [of pressure,] to keep you alive in the vacuum of space,” said Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT. “We want to achieve that same pressurization, but through mechanical counterpressure — applying the pressure directly to the skin, thus avoiding the gas pressure altogether. We combine passive elastics with active materials.”

>Newman has been working on a flexible, form-fitting spacesuit for the last decade. In that time, she and colleagues have engineered “active compression garments” that use “small, springlike coils that contract in response to heat.” The coils are built out of shape-memory alloy (SMA), which essentially creates a smart spacesuit that (after heating) “remembers” its engineered shape after being bent or deformed by an astronaut's body.

...

>“You could [also] use this as a tourniquet system if someone is bleeding out on the battlefield,” Holschuh said. “If your suit happens to have sensors, it could tourniquet you in the event of injury without you even having to think about it.”

I wounder how they would account for accidental hardons?

I think you'd just have to place it at 12 o'clock, and pray for mercy from the boner gods.

IIRC current designs have you wearing pressurised gloves, helmet and crotch guard.
>> No. 6504 ID: 604f11
not seeming like such a great idea to me.
There are ways to check a space suit for leaks, but there isnt any way to easily check elasticity in every part of a full body suit, not to mention some parts would wear out faster than others and the entire thing would have to be replaced unless it were made in separate components. Not to mention the bulky space suit kills two birds with one stone in a manner of speaking in that it keeps the body pressurized and supplies oxygen.

The problem with these suits is the lack of cooling systems.

In space, your body can't get ready of excess heat. There's no air to conduct it away from you, and you generate WAY more heat than you can lose by radiative cooling. We almost lost one of our astronauts in an early spacewalk because his suit filled up to the groin with sweat and his body heat was so high he nearly had a stroke. A big part of the current space suit design is a water-cooling system that surrounds the entire body. Its more than just pressure and oxygen.

They could add in that sort of cooling system, I would expect, either as an underlayer like it is now or as an external apparatus that bolts on. I don't think these suits are intended for the same kind of heavy duty work that an EMU is intended to do though, so holding them to the same standards might be flawed. If it can keep you alive in space for about an hour without you worrying about heat, that might be enough time to go out, fix what needs to be fixed, and nip back in for a cool cup of water and a sponge.

Or, you know, could just get use as an emergency sort of suit work whenever possible in case of fuckups/breaches. Just possible thoughts.

The pressure suit is the base layer. It would be rather easy to add in several more layers for various purposes. Currently it is envisioned that the suit would be worn with a solid chest piece/helmet/backpack combo.

It looks like it would be pretty simple to build a cooling system into the garment.

From Wiki:
>A Liquid Cooling Garment (LCG) is a form-fitting garment that is used to remove body heat from the wearer in environments where evaporative cooling from sweating and open air convection cooling does not work, or the wearer has a biological problem that hinders self-regulation of body temperature.

It's using electrical resistance in the coils to expand and contract them, of course you can measure that.

So why do we need constrictive pressure anyway?
Isn't it enough that the suit is airtight and doesn't stretch and expand like a balloon? The body won't have any space to expand, so the pressure will be the same as sea-level. Kind of like a bicycle tyre: Inner tube has high pressure and wants to expand, but it can't so it holds shape.
What am I missing?

No hardon is accidental.

Not really. Of course, you don't need as much space as you have in modern space suits, because they've been made for entirey different purpose - reliability, and reliability only.

Of course, this might be way to go, new materials and technology that will allow to secure both shape and pressure - which is what this design needs. But of course, two-layer structure is essential, and there will be nothing "skin-tight" in this design.

This is entirely wrong concept. You will need a protection from both vacuum and temperature, and also there are sun rays and micro meteorites. This is the difference between "space suit" and "pressurized suit". I'm not really sure if this confusion is intentional, but such design would be only useful for modern concept of "space tourism", which is actually just a "thermosphere jumping".

Correct. In addition to being a vacuum suit it needs to provide at least minimal protection against radiation and have a cooling system.

I can't wait for this:

>3 Our spacesuit design is finally coming together and will also be unveiled later this year. We are putting a lot of effort into design esthetics, not just utility. It needs to both look like a 21st century spacesuit and work well. Really difficult to achieve both.
