The Gemini 4, also known as the Gemini IV, was a NASA space mission which was completed by American astronauts in June 1965. Also, it was the first NASA operation in which ground control headquarters were located in the Houston Mission Control Center. The mission featured the first internationally broadcast spacewalk, as well as the first spacewalk attempted by an American. On June 3, 1965 James McDivitt and Edward White, the two crew members manning the spacecraft used for the mission, were rocketed into space. Interestingly enough, the space shuttled used for Gemini IV didn't have an official name. On the same day, Edward White did a spacewalk for over fifteen minutes. Although the astronauts conducted experiments and other activities during the course of the four day mission, White's accomplishment overshadowed anything else done during the course of the NASA operation.
