Collection Item Summary:
This Hand-Held Maneuvering Unit, which operates on compressed oxygen, is similar to the one used by Edward White III on his historic spacewalk in June 1965. It is constructed of aluminium and stainless steel, with three small rocket nozzles, two of which are located on extended "arms," permitting the astronaut to move his body gently to the right, left, or forward. A rocker switch on the handle operates the nozzles. The two oxygen tanks maintained under 3400 psi of pressure for fuel.
The unit was manufactured by Airesearch Manufacturing Company, and NASA transferred it to the Smithsonian in 1973.
