Fits like an EVA glove.

Astronaut Jeff Williams does the final fit check for his custom EVA gloves at NASA's Johnson Space Center. Williams will conduct EVAs during his mission aboard the International Space Station. Jeff Williams arrives at the International Space Station on October 2, 2009 after launching from Baikonur Cosmodrome in Kazakhstan.

How much pressure can these gloves take?

Cool. I see the Astronauts check the condition of their gloves from time to time during EVA. Naturally wear occurs from hours of working and moving (I guess you can say the gloves are your shoes on EVA) around outside, but how many sets of gloves does a space walker have on Station (or any one mission)? How would an Astronaut change them if they need to in the middle of EVA?

@libbern I don't know all the details, but from a biological point of view, you just need to have the same partial pressure of oxygen as here on Earth, which at sea level is around 3 lb psi.

@apollotls

That low?:O Not that I understand how that can be, but interesting to know.

@libbern The "air" inside a pressurised suit is 100% oxygen. One of the consequences of this is that the suit doesn't need to be pressurised to a level as high as 1 bar. At 1 bar the suit would become far more rigid, <hich is obviously not desirable. I don't know the exact pressure they use but it's around 4 lb psi.

the gloves wasnt pressurized (spell?)

wow my uncle works there at NASA!

The EMU is designed to operate at 4.3 psi. I don't know what the maximum pressure is though.

[libbern]

I presume that the inside pressure is about 1 atm (bar). That is, about 10 ton per square meter. So the inside-out pressure would be about that, as the pressure in space, of course, is as good as 0 bar. I, not sure, but it makes sence that they use 1 bar.

Cool!
