context_page_description: Gemini 4 was the second crewed spaceflight in NASA's Project Gemini, occurring in June 1965. It was the tenth crewed American spaceflight. Astronauts James McDivitt and Ed White circled the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the Soviet Vostok 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.
  The flight also included the first attempt to make a space rendezvous as McDivitt attempted to maneuver his craft close to the Titan II upper stage which launched it into orbit, but this was not successful.
  The flight was the first American flight to perform many scientific experiments in space, including use of a sextant to investigate the use of celestial navigation for lunar flight in the Apollo program.
context_section_description: Gemini 4's crew originally intended to call their spacecraft American Eagle, but this was rejected after NASA management issued a memo saying that they did not want a repeat performance of the previous mission, on which Gus Grissom had named his spacecraft Molly Brown.
  The callsign for the mission became simply Gemini 4. There was no patch flown on the crew's suits, although the one shown here, created after the fact, is on display in McDivitt's museum. Since McDivitt and White were prohibited from naming their spacecraft, they decided to put the American flag on their suits, the first astronauts to do so, although Soviet crews wore the Cyrillic "СССР" on their spacesuit helmets. Previous astronauts had only had the NASA insignia and a strip with their name on their suits.
  The flight was commemorated on a pair of US postage stamps in 1967.
