![]() ![]() The second adjustment was made near apogee of the second orbit, and raised both the apogee and perigee by adding 49 feet per second (15 m/s) to their speed. Their first course adjustment was made at one hour and 34 minutes into the mission, when the astronauts lowered their apogee slightly with a five-second Orbit Attitude and Maneuvering System (OAMS) thruster burn. Rendezvous and docking The Agena Target Vehicle as seen from Gemini 8 during rendezvous. Gemini 8's launch was nominal and no significant anomalies occurred with either the Titan II or the spacecraft. The Gemini spacecraft was launched into an 86-by-147-nautical-mile (159 by 272 km) orbit by a modified Titan II on Ma(coincidentally the 40th anniversary of the launch of the world's first liquid-fuelled rocket by Dr. Everything worked perfectly the Agena put itself into a 161-nautical-mile (298 km) circular orbit and oriented itself to the correct attitude for the docking.Ī Gemini-Titan launch vehicle lofts Gemini 8 into orbit, March 16, 1966. Flight Agena and Gemini launch The Agena Target Vehicle is launched into space on an Atlas rocket in preparation for Gemini 8įive months earlier, NASA had launched an Agena Target Vehicle for Gemini 6, but the Atlas-Agena launch failed when the Agena's engine exploded during orbital injection and the mission had to be rescheduled. The flight also carried an additional three scientific, four technological, and one medical experiment. He would practice several maneuvers in formation with the Gemini and Agena vehicles (separated at distances up to 60 feet (18 m), in concert with Armstrong in the Gemini. This was a backpack with a self-contained oxygen supply, extra Freon propellant for his Hand Held Maneuvering Unit, and a 75-foot (23 m) extension to his tether. ĭuring the EVA, after Armstrong undocked from the Agena, Scott was to don and test an Extravehicular Support Pack (ESP) stored at the back of the spacecraft adapter. Then he was to move back to the Gemini and test a minimum-reaction power tool by loosening and tightening bolts on a work panel. On a 25-foot (7.6 m) tether for one and a half revolutions around the Earth, Scott would have retrieved a nuclear emulsion radiation experiment from the front of the Gemini's spacecraft adapter, then activate a micrometeoroid experiment on the Agena. ĭuring the first docking, Pilot David Scott planned to perform an ambitious, two-hour-and-10-minute extra-vehicular activity (EVA), which would have been the first since Ed White's June 1965 spacewalk on Gemini IV. This was to be the first space docking in history. After being launched into an 87-by-146-nautical-mile (161 by 270 km) orbit, on the fourth revolution it was to rendezvous and dock with an Agena target vehicle, which had been earlier launched into a 161-nautical-mile (298 km) circular orbit. Gemini VIII was planned to be a three-day mission. Apogee (max): 298.7 kilometers (161.3 nautical miles).Perigee (min): 159.8 kilometers (86.3 nautical miles).civilian flew into space (after Joe Walker on X-15 Flight 90), and the first time a U.S. Naval Reserve in 1960.( On August 29, 1951, Armstrong saw action in the Korean War as an escort for a photo reconnaissance plane over Songjin.) His flight marked the second time a U.S. civilian flew into orbit.Ĭommand pilot Neil Armstrong resigned his commission in the U.S. civilian flew into space and the first time a U.S. The crew returned to Earth safely.įlown by pilot David Scott and command pilot Neil Armstrong, the flight marked the second time a U.S. spacecraft which threatened the lives of the astronauts and required an immediate abort of the mission. ![]() The mission conducted the first docking of two spacecraft in orbit, but also suffered the first critical in-space system failure of a U.S. It was launched on March 16, 1966, and was the 14th crewed American flight and the 22nd crewed spaceflight overall. Gemini 8 (officially Gemini VIII) was the sixth crewed spaceflight in NASA's Gemini program.
