High Quality Content by WIKIPEDIA articles! The Space Shuttle/International Space Station Extravehicular Mobility Unit is an independent anthropomorphic system that provides environmental protection, mobility, life support, and communications for a Shuttle or ISS crew member to perform extra-vehicular activity in earth orbit. It is a two-piece semi-rigid suit and it is currently one of two space suits used by crew members on the ISS, the other being the Russian Orlan space suit. The suits are white to reflect heat and to stand out against to the blackness of space, the red stripes also serve to easily locate an astronaut. The EMU, like the Apollo/Skylab A7L spacesuit, was a result of years of research and development. It consists of a Hard Upper Torso assembly, a Primary Life Support System which incorporates the life support and electrical systems, arms, gloves, Apollo-style "bubble" helmet/Extravehicular Visor Assembly, and a soft Lower Torso Assembly, incorporating the Body Seal Closure, waist bearing, brief, legs, and boots.
