    This is a replica of a
NASA EVA Space Suit with a Manned Maneuvering Unit (MMU). The MMU is a one-man, nitrogen propelled backpack that attaches to the back of the astronaut's space suit.

   Using hand controllers, the astronaut can fly with precision in or around the orbiter cargo bay or to nearby free-flying payloads or structures, and can reach many otherwise inaccessible areas outside the orbiter. 

  Astronauts wearing MMU's have deployed, serviced, repaired, and retrieved satellite payloads and also use them on the orbiting
 International Space Station.

The MMU propellant is gaseous nitrogen which is stored under high pressure and can be recharged from the space shuttle. The MMU weighs 310 pounds and can include a camera that is operated by the astronaut while working.

The shuttle MMU Manned Maneuvering Unit was originally designed for maneuvering untethered from the shuttle and allows crew members to move as far as 300 feet from the orbiter.
    The MMU is designed to provide EVA support for as much as six hours at a time. The gas propellant is fed to twenty-four thruster jets. Two pressurized nitrogen tanks can be filled from the orbiter's on-board supply. All systems on the MMU are dual redundant (if one system fails, the second system can take over completely).
    Project Gemini in 1965 provided NASA with the first experience with extravehicular activity in space using two different types of  maneuvering devices. One was a Hand Held Unit or HHMU. The second device was a backpack called the Astronaut Maneuvering Unit (AMU).
