This Hand-Held Maneuvering Unit was used by Edward White III on his historic "walk in space" on June 3, 1965.
It is constructed of aluminium and stainless steel, with three small rocket nozzles, two of which are located on extenders, permitting the astronaut to move his body to the right or left, or gently forward. There is a rocker switch incorporated into the handle for the operation of the nozzles, and two oxygen tanks under 3400 psi of pressure for fuel.
The unit was manufactured by Airesearch Manufacturing Company and transferred to the National Air and Space Museum in 1967.
