Gemini 11 was the ninth crewed mission of the NASA's Project Gemini. It was commanded by Command Pilot Charles "Pete" Conrad, Jr. and Pulot Richard F. Gordon, Jr. The crew performed a direct-ascent rendezvous with the Agena Target Vehicle on the first orbit and used the Agena rocket engine to put the combined craft in a higher orbit. Astronauts also performed two EVAs and conducted various scientific experiments. The mission started on September 12, 1966, 14:42:26 UTC and, having performed the first totally automatic, computer-controlled reentry, it ended on September 15, 1966, 13:59:35 UTC.
Low Earth OrbitThe Transit-O series of satellites that closely followed the design of Transit 5C-1 were also called “Oscars” (Oscar is the phonetic alphabet for “O”, i. e., operational). They were also called NNS (Navy Navigation Satellite) or shortened NavSat.
Polar OrbitPioneer A to E (Pioneer 6 to 9 after launch) were a series of five solar-orbiting, spin-stabilized, solar-cell and battery-powered satellites designed to obtain measurements of interplanetary phenomena from widely separated points in space on a continuing basis.
Heliocentric N/AThe Program 206 satellite, carrying the KH-7 (Keyhole 7) camera system (codenamed Gambit-1), was the first successful high resolution space reconnaissance program. It was managed by NRO's Program A, the USAF-led segment of the National Reconnaissance Program managed from Los Angeles AFB in El Segundo, California.
