Gemini 4



DescriptionGemini 4 (officially Gemini IV) was the second manned space flight in NASAs Project Gemini, occurring in June 1965. It was the tenth manned American spaceflight (including two X-15 flights at altitudes exceeding 100 kilometers (54 nmi)). AstronautsJames McDivitt and Edward H. White, II circled the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the SovietVostok 5. The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately 20 minutes. Both of these accomplishments helped the United States overcome the Soviet Union's early lead in the Space Race.
