This hand-held maneuvering unit is similar to that 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 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. The two oxygen tanks which were attached to this unit would have been under 3400 psi of fuel pressure, but they are missing.
The unit was manufactured by Airesearch Manufacturing Company, and NASA transferred it to the Museum in 1975.
