What is a space suit?
A space suit is a protective clothing that astronauts wear when they are outside the spacecraft. This suit provides them with air and water and at the same time protects them from radiation, flying debris and extreme temperatures. If necessary, the space suit also acts as a mini spacecraft, allowing the astronaut to return to the cosmic vessel or space station if it separates. A special sight is attached to the helmet to protect Astronaut's eyes from the sun. These suits are also known as mobility units for mobility or EMU. This backpack provides an astronaut's oxygen while it is outside the spacecraft and destroys carbon dioxide as exhaled. The backpack also houses a water tank for cooling and produces electricity for a space suit. This is called simplified assistance to save extravahicular activity or safer. Safe is a preventive measure that allows the astronaut to return to the spacecraft or space station if it separates it for some reason.
A space suit must protect astronaut from many environmental extremes. Astronauts face temperatures that are 250 degrees Fahrenheit (120 degrees Celsius) to a cold -250 degrees Fahrenheit (-160 degrees Celsius). The space consists of many layers of specialized substances, including composite materials with high strength, ortho-fabric, dacron, nylon/spandex, neoprene-coated nylon, urethan coated with nylon, tricot, aluminized mylar and stainless steel.
Each part of the cosmic suit is made separately and then connects. The chest or upper body of the astronaut is covered with a unit that is made of hard materials. For arm and hands covers, softer, more pliable wonderful, it is used to allow a larger range of movement. For the head, the specialized helmet is designed to protect the head, allowing as much visibility as possible. The lower half of the suit covers the legs and noHy.
Astronauts do not wear regular clothing under a new suit, wearing specially designed garments that have a woven tube into the fabric. This clothing covers and keeps the body cooling water through the tubes. It fits very tight to the body of the astronaut, but does not cover the head, hands or legs.
