Known in layman terms as “Space Suit”, the Extravehicular Mobility Unit (EMU) is actually a personal spacecraft. It has 14 layers between the astronaut’s skin and the vacuum of space, in three assemblies: the liquid cooling garment assembly to keep the astronaut from overheating, the pressure garment assembly to retain air pressure within the suit and the thermal micrometeoroid garment assembly to reflect the sun’s heat and stop small bits of flying space debris. Other luxuries in the suit include a one liter drink bag, providing water during space walk and a maximum absorbency garment (an adult diaper!) for those awkward moments of life.
