Wallpaper Description:
Do you know What is an astronaut's space suit made out of?
Starting from top and progressing to the bottom, the first part of the suit is the helmet. Channeling cool, fresh oxygen to the astronaut's face is only one of the functions of this headset. The clear, double-pane helmet bubble is made of high-impact Lexan, which is a kind of plastic. A plastic metal cowl over the helmet protects it from impacts and mounts both work lights and TV cameras.

The Hard Upper Torso is the top portion of the suit and is made of fiberglass and steel and provides a hard shell of protection around the astronaut's chest, back, and shoulders. There are flexible metal bearings at the shoulders that permit the arms to rotate and swivel front to back. The arms and gloves are adjustable in length and attach to the shoulder bearings. The helmet attaches to a metal seal at the top of the HUT, which is built right into a life-support backpack. Then we move onto the Lower Torso Assembly which has been dubbed the "pants" of the suit. The waist area and legs are made of soft layers of insulation, neoprene rubber, and Kevlar, which both hold pressure and protect the astronaut. The "pants" bend at a waist ring and at knee joints and has "attach points" at the bottom for the boots.

The Portable Life Support System backpack is what contains the machinery needed to keep an astronaut alive in the harsh environment of space. This pack is built into the rear of the hard upper torso, and contains the suit's oxygen, batter, and water supplies. The PLSS also has dual radios to provide communications back to the orbiter, the space station, and Mission Control. The Liquid Cooling and Ventilation Garment is what has been dubbed the "astronauts set of long underwear." It basically consists of a spandex body that is laced with thin water lines, which circulate cooled water from the backpack next to the astronaut's skin. The warm water and air collected by the tubes and by ventilation ducts is piped back to the backpack for cooling and removal of carbon dioxide.

Space suits today are composed of 12 layers. The outside of the space suit is made of a combination of substances that includes Kevlar, which is the material used to make bullet-proof vests and it is there to protect astronauts from micrometeorites, which are actually like tiny bullets in space. The seven layers inside of that are all designed to protect the astronaut from extreme temperatures. There are then other material used to pressurize the suit and then there is the innermost layer, the LCVG, which was aforementioned. The suit weighs over 280 pounds on Earth, but weighs nothing in space. An astronaut has supplies in his or her suit to work outside for up to eight hours.

Every astronaut owns a individual space suit that fits perfectly !
One space suit is worth a fortune (a few million $ I think).
The airco protects an astronaut for very hot/cold temparatures (from +150°C in the sun to -170¨C in the shadow). The pressure in the suit avoids that the blood will begin to boil
in space. And the many layers protect against harmful cosmic radiation.
