Collection Item Summary:

Gemini 11 was launched on September 12, 1966, on a 3-day mission. Astronauts Pete Conrad (commander) and Dick Gordon (pilot) rendezvoused and docked with their Agena target vehicle on their first orbit around the Earth, pioneering a technique that would later be used in the Apollo lunar landings. The astronauts used the Agena's engine to reach a record-setting altitude of 1370 km (850 mi.). Dick Gordon also performed a 38 minute space walk in which he fastened a tether to the docked Agena. Artificial gravity was simulated by separating the Gemini from the tethered Agena and firing thrusters to create a slow spin. But Gordon experienced overheating and exhaustion during his space walk which showed that the problems of extra-vehicular activity (EVA) had not yet been solved.

The National Aeronautics and Space Administration transferred Gemini 11 to the Smithsonian in August 1967.
