This is the right donning handle for the Space Suit Assembly/Extravehicular Mobility Unit (EMU), the current U.S. spacesuit for spacewalks outside the International Space Station. The EMU is a modular and massive spacesuit. Astronauts must select and fit components out of an existing inventory of parts to assemble the complete suit. The entire suit, including the life support system can weigh as much as 275 lbs. For these reasons, astronauts need specialized tools to assist them in putting on the suit. The donning handles, left and right, are machined tools that lock in to the waist bearing of the suit so the astronaut can lift the lower half of the suit evenly with tearing the fabric components or bending the metal components. This donning handle was used for training.
