Introduction
To explore and work in space, the astronauts must carry their environment because there is no oxygen and atmospheric pressure to sustain life. The spacesuit is more than clothes an astronaut puts on in space. It’s really a small spacecraft. Its main work is to protect the astronaut when in space. Astronauts needs to put on spacesuits at any time they leave a spacecraft and are exposed to the surrounding space. In space, air to breath and air pressure is not available. Space has dangerous radiation and is extremely cold so without protection, an astronaut would rapidly die in space. The design of spacesuits is such that it protect astronauts from the radiation, cold and low pressure in space and furthermore provide air to breathe. Wearing a spacesuit permits an astronaut to be able survive and work in space. They also keep the astronaut from getting hurt by the space dust. The space dust always travel at a very high speed and may cause hurt to the astronaut. Moreover the suits holds drinking water for the astronaut.
The spacesuit is made up of many parts that perform different roles. One of the parts protect the chest, another part covers the arms and connects to gloves and the helmet protects the head. The last part of this suit covers the astronaut’s feet and legs. Other parts of this suits are made up of many layers of material. The layers each performs different roles; some protect the astronaut from space dust while others keep oxygen for the astronaut. Below the suit, the astronaut wear a piece of cloth which covers their body except at the head, feet and hands. Tubes are woven within the suit to allow water flow that keeps the astronaut cool. At the back of the suit exist a backpack which holds oxygen used by the astronaut for breathing and removes carbon dioxide breathed out by the
