Astronaut Edward H. White II, pilot for the Gemini-Titan 4 mission, will use a hand-held self-maneuvering unit like the one pictured here when he steps into space from the GT-4 spacecraft. The device is used in a zero-gravity environment. It is an integral unit that contains its own high pressure metering valves and nozzles required to produce controlled thrust. A camera is mounted on the front of the unit to allow White to photograph the launch vehicle second stage, the Gemini spacecraft and Earth. As a safety measure, the unit is attached to the extravehicular astronaut by a cord that fastens to the arm of the spacesuit.
