Extravehicular Mobility Unit

Extravehicular Mobility Unit (EMU) is a spacesuit used by astronauts for performing activities outside of their spacecraft. It is designed to provide life support, mobility, and protection to the wearer in the harsh environment of space. The EMU consists of several components, including a helmet, gloves, boots, a torso assembly, and a backpack that contains a variety of systems such as oxygen, cooling, and communication. The EMU is custom-fitted to each astronaut and is designed to be highly modular, allowing for easy replacement of individual components. The EMU has been used for a variety of tasks, including spacewalks, satellite repair, and assembly of the International Space Station.
