Narrative Description

Protection and Clothing

            An astronaut suit has to have a pressurized atmosphere to prevent your bodily fluids from boiling.

            Space suits cannot use normal air of 78 percent nitrogen, 21 percent oxygen.  The low pressure would cause dangerously low oxygen.  Most spacesuits provide a pure oxygen atmosphere for breathing.

            An astronaut breathes out carbon dioxide.  The concentration of carbon dioxide would build up to deadly levels.

            The materials of a spacesuit are ortha-fabric, aluminized Mylar, neoprene-coated fibers, Dacron, urethane-coated nylon, tricot, spandex, stainless steel, and high strength composite materials.  All the materials have to be maneuverable and some for comfort.

            The water connector is for drinking water in space, when they get tired from working.  They communicate with the people on earth to give them information about their work.  The scissor pocket is for cutting ice crystals for a sample.  They have a tank of oxygen in the space shuttle they brought from earth.  That’s how they get their oxygen.
