A pool has nothing to do with the vacuum, it has to do with buoyancy and simulating weightlessness. They wear the suits in a simulated weightless environment for training.
So these suits can work under water pressure and in a vacuum while being flexible? Amazing what they could make in 1969
You don't have to be in vacuum to prove it. You can prove it on earth by pressurizing the suit above atmospheric pressure. They don't pressurize them to 1 ATM in space, they do it lower and increase the oxygen so the partial pressure is the same.
Why do you think joints can't work? It isn't a balloon. It's seriously not the most complicated thing.
Dive down 30 feet in a diving pool. That's the difference in pressure from space to the bottom of the atmosphere. You can't wrap your head around engineering around that difference in pressure? I mean come the fuck on man.
They don't pressurize them to 1 ATM in space, they do it lower and increase the oxygen so the partial pressure is the same.
Interesting, I did not know this.
Yeah it was 1969 not 1869. We also fly aircraft from the 1950s (B52, U2), the SR71 flew in 1969, hell the V2 was built in the 40s. Why is a pressure suit amazing to you?
Just think about it.. if your inside a vacuum and it was pressurized wouldn't you need the joints to be some how separated or a solid exoskeleton type suit? If you pressurized the entire suit wouldn't the legs and arms be stiff?
And why recently has nasa said it will take 4 years to devekope suits for a trip to the moon?
