A spacesuit is much than a set off clothes astonauts wear on spacewalks. A fully equipped spacesuit is really a one-person spacecraft.

A spacesuit including the Hard Upper Torso covers the astronaut's chest. The Arm Assembly covers the arms and connects to the gloves. The helmet and Extravehicular Visor Assembly protect the astronaut's head while still allowing him or her to see as much as possible. The lower Torso Assembly covers the astronaut's legs and feet. The flexible parts of the suit are made from several layers of material. The layers perform different functions, from keeping oxygen within the spacesuit to protecting from space dust impacts.
