Pioneer 11 is what NASA is all about – exploration beyond the frontier." [31] Besides announcing the end of operations, the dispatch provided a historical list of Pioneer 11 mission achievements. NASA terminated routine contact with the spacecraft on September 30, 1995, but continued to make contact for about two hours every two to four weeks ...
The Pioneer programs were two series of United States lunar and planetary space probes.The first program, which ran from 1958 to 1960, unsuccessfully attempted to send spacecraft to orbit the Moon, successfully sent one spacecraft to fly by the Moon, and successfully sent one spacecraft to investigate interplanetary space between the orbits of Earth and Venus.
The Pioneer program was a series of NASA uncrewed space missions designed for planetary exploration. There were a number of missions in the program, most notably Pioneer 10 and Pioneer 11, which explored the outer planets and left the Solar System.
Mission Type Outcome 1 Pioneer 11: Pioneer 11: 6 April 1973: Atlas SLV-3D Centaur-D1A [3] NASA: Flyby Successful First probe to reach Saturnian system. Closest approach on 1 September 1979 at 16:31 UTC. Flew past Iapetus, Dione, Mimas, Tethys, Enceladus, Rhea and Titan at long distances. Discovered Epimetheus and Janus. [7] 2 Voyager 2: Voyager ...
Approved by NASA in February 1969, [10] the twin spacecraft were designated Pioneer F and Pioneer G before launch; later, they were named Pioneer 10 and Pioneer 11 respectively. They formed part of the Pioneer program, [11] a series of United States uncrewed space missions launched between 1958 and 1978. This model was the first in the series ...
The central theme of this issue involves the first actual 'in space' flights of the Space Shuttle and also pays tribute to twenty years of U.S. crewed space exploration. The other stamps to the left and right sides are honoring the efforts of those who partook in the historical Moon walk, Skylab, and Pioneer 11 missions. The images were modeled ...
The Pioneer anomaly, or Pioneer effect, was the observed deviation from predicted accelerations of the Pioneer 10 and Pioneer 11 spacecraft after they passed about 20 astronomical units (3 × 10 9 km; 2 × 10 9 mi) on their trajectories out of the Solar System.
From 1970 to 1975 he worked at NASA Ames Research Center where he wrote, as a part of the Pioneer 10/Pioneer 11 mission control operating system, both the telemetry monitoring and real time display of the images of Jupiter. He joined Stanford University in August 1975 as a member of Dr. Elliott Levanthal's Instrumentation Research Laboratory ...
