ObjectivesThe main aim of this 4 Ground days flight and 62 turns was to fly in formation with the second stage of the rocket Titan II which had just put the Gemini vessel in Orbite. The goal was to develop the techniques of orbital rendezvous.
L' event headlight of this flight was the exit extravéhiculaire 22 minutes of White, the first for American. On the ground, the mission was followed for the first time from the new control center of NASA located close to Houston at the Texas.
Course of the flightIt was the first of the space conquest to have an international audience because for the first time launching was retransmis on line in 12 countries of Europe thanks to the satellite Early Bird. The use of the Propellent S and the comprehension of orbital mechanics more difficult than were envisaged and the flight in formation with the second stage of the rocket was abandoned with the profit of the exit extravéhiculaire. As White appeared tired, McDivitt decided a rest and the exit was done after the third Orbite. After Depressurization of the cabin, White left by the port-hole and moved in the vacuum thanks to a gas jet gun during about fifteen minutes. After that, various experiments were carried out like measurements of Radiation S or position compared to star S.
