It’s made of plastic. While my drysuit has the brass type, some of the latest designs have the plastic type. Personally, I ,much, prefer the brass dry zippers, as they appear to be ,much, more robust. In Tim’s pictures of ,Space, X’s ,Space Suit,, I don’t see any such airtight zippers anywhere.
Spacesuits for the ,space, shuttle era are pressurized at 4.3 pounds per square inch (psi), but because the gas in the ,suit, is 100 percent oxygen instead of 20 percent, the person in a spacesuit actually has more oxygen to breathe than is available at an altitude of 10,000 feet or even at sea level without the spacesuit.
Pressure ,suits, are actually surprisingly low-tech. Early models dating to the 1930s were completely homemade, and even the ,suits, the Apollo astronauts wore on the moon were sewn by seamstresses on loan from Playtex. Commercial off-the rack ,space suits, run into the six figures, but Smith’s goal is more modest: $1,000, start to finish.
The outer part of the ,suit, is a flame-resistant Nomex material that is ,much, stronger than the inner layer and gives the ,suit, its shape. With the helmet, visor and gloves locked in place, the ,suit, fully encloses the astronaut in an air bubble inflated to 3.5 pounds, about the same air pressure as a person would find 30,000 feet above Earth.
