Just so everyone knows, the suit they are talking about is reflected in the 2nd picture - not the first picture. I saw this presented earlier this year and it's an interesting concept. Basically you enter through the neck ring and then the hard parts of the suit close into their proper positions based on your anthropometry.
The first sci-fi picture is, notionally, representative of a mechanical counterpressure suit, but not what this article is about. Gizmodo added it in to get more article hits. Well played, by the way.
@shane.m.mcfarland001: I was honest and pointed that out: "Ok, so maybe the real suit isn't quite as slinky as the one on Jane Fonda there, but it's incredible anyway."
Mind you, I maintain that the Fonda version is much more appealing aesthetically.
Out of curiosity, did you get to see them removing the suits? Is the process just as quick in reverse or is there a different procedure?
Just because they manage to make installing yourself in a spacesuit faster doesn't mean it'll be any more comfortable than the current models. I watched the NOVA special on the Hubble repair mission, and two of the things that really stood out were that wearing the suit in the neutral bouyancy pool only means that the _suit_ is neutrally bouyant (_YOU_ are still gonna be resting the full weight of your body on your collarbones if your feet are pointed at the ceiling), and that the gloves are so physically abusive to work with that many astronauts end up losing fingernails. Another interesting thing was finding out that those suckers weigh 300 pounds, and you have to be hoisted in and out of the neutral bouyancy pool with some sort of elevator that actually holds the torso of the spacesuit up (you actually have to climb up into the torso section). Makes being the payload arm operator all the more enticing...
@Purple Dave: There's no weight in space though. You'll still have to deal with the added mass and the enerta that it adds to your movement, but the weight on your collar bones is a non-issue in space.
@Purple Dave: Something else mentioned in the NOVA special: The suits are pressurized, and this internal pressure makes it harder to bend limbs, move fingers, etc. because it creates resistance with every movement. The current NASA suits are only pressurized to 4.3 psi, well below Earth normal 14.7 psi.
@barrywoods:
Yes, in space you float inside of the suit. But on Earth, in the neutral bouyancy pool, where they spend days upon days practicing their spacewalk missions, you don't float inside the suit. At all.
@AlphaPepper:
I guess I didn't catch that part (plan to rewatch it at some point, though), but it would certainly explain why they lose so many fingernails. Opening the fingers on your hand would require pushing the suit gloves open with backs of your fingers, and most of that pressure would go straight onto your fingernails.
Your dream came back when you realized you could, one day, get in a skin-tight rubber suit? Really now, remember who the audience is? I mean, it's like 90% Frucci.
This type of suit has been looked at for a long time, especially for endurance missions due to their lighter weight. MIT is working on one called "Bio-Suit". Kinda neat stuff. Think of it as super advanced Under Armour.
I bet that in that orange jumpsuit, we would have tons of astronaut casualties because someone, in all the excitment of getting to go out into space, forgot to zip his fly up. "Hey Jimmy, cows out of the barn" "What? Oh Shit" as a Jimmy popsicle floats through space it will a warning to all to always check your zipper.
@Storm490: Fortunately, Jimmy has an extensive checklist to go through, as well as someone else helping to "check his zipper", before they exit the airlock.

How is that different from how women normally dress?

Granted that speed may have something to do with permanently looking like I just rolled out of bed...
