Sep. 14, 1966: Photograph of Agena at time of tether drop; range 50 feet; taken during the Gemini XI mission during orbit no. 33. Astronauts Pete Conrad and Dick Gordon performed the first direct-ascent (first orbit) rendezvous with an Agena Target Vehicle, docking with it 1 hour 34 minutes after launch; used the Agena rocket engine to achieve a record high-apogee Earth orbit; and created a small amount of artificial gravity by spinning the two spacecraft connected by a tether. Gordon also performed two extra-vehicular activities for a total of 2 hours 41 minutes.
