Astronaut Edward H. White II, pilot for the Gemini-Titan 4 space flight, floats in zero gravity of space. The extravehicular activity was performed during the third revolution of the Gemini 4 spacecraft. White is attached to the spacecraft by a 25-ft. umbilical line and a 23-ft. tether line, both wrapped in gold tape to form one cord. In his right hand White carries a Hand-Held Self-Maneuvering Unit (HHSMU). The visor of his helmet is gold plated to protect him from the unfiltered rays of the sun.
