This 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. This component is the Waist Thermal Micrometeoroid Garment (TMG) that fits around the lower torso of the suit. The TMG provides protection against micrometeoroids and the wide variations of temperatures when the astronaut is working in open space. This particular component never flew in space, but astronauts used it for training on Earth.
The National Aeronautics and Space Administration transferred this object to the museum in 2010.
