This is a Hard Upper Torso Assembly (HUT) from a Space Shuttle type spaceesuit. It is one component of the extravehicular spacesuit that astronauts use to perform spacewalks from the Space Shuttle and the International Space Station. The Extravehicular Mobility Unit (EMU) consists of two major systems: The Space Suit Assembly (SSA) and the Life Support System (LSS). Unlike previous generations of spacesuits, the SSA is not custom made for individual astronauts, but consists of interchangeable and reusable components that each astronaut chooses to fit his or her body. The HUT is part of the rigid structure of the spacesuit that seals the air pressure inside the suit while the astronauts works in open space. This version of the HUT was introduced at the beginning of the Space Shuttle program and features the "hinged" or "pivoted" shoulders that allow the astronauts greater ease when climbing into the spacesuit. This particular component never flew in space, but astronauts used it for training on Earth.
NASA Johnson Space Center transferred this object to the museum in 2010.
