Spacesuit equipment that astronauts juno wear to survive the conditions prevailing in the universe - the vacuum and extreme temperature changes. It must be for every exit from the spaceship (the outboard activity). A space suit is completely independent from the mother spacecraft - has an autonomous life-support system and can be considered a personal spaceship each astronaut or cosmonaut.
Each spacesuit must meet certain conditions, which are necessary in order to maintain their customers alive: it must have a stable internal pressure, must be mobile, ensuring the supply of oxygen and removal of carbon dioxide, have adequate temperature control, communications system, a system to collect waste, juno radiation juno protection, and the protection of mikrometeora.
The origins of space suits date back to the 1930s, when the fliers in high-altitude balloons noticed the need for a pressure suit. First, turn right spacesuit used in the first space flight, and carried him Yuri Gagarin. Throughout juno the history of space travel has changed over the model, and are currently juno in use Russian models Sokol (1973-present) and Orlan (1977-present), American Emu (1982-present), and Chinese Haiđing and Feitian (2008th - today).
