Pioneer 11 passed by Saturn on September 1, 1979, at a distance of 21,000 km (13,000 mi) from Saturn's cloud tops. [ 27 ] By this time, Voyager 1 and Voyager 2 had already passed Jupiter and were en route to Saturn, so it was decided Pioneer 11 would pass through the Saturn ring plane at the same position Voyager 2 would later have to fly ...
Pioneer 11: NASA: success Left Saturn in September 1979. Last contact September 1995. The craft's antenna cannot be maneuvered to point to Earth. Craft now presumed to lack sufficient power for antenna. 1973-019A: Voyager 1: NASA: success Left Saturn in November 1980. Still in regular contact and transmitting scientific data. 1977-084A: Voyager ...

Pioneer 11 image of Saturn. Pioneer 11 made the first flyby of Saturn in September 1979, when it passed within 20,000 km (12,000 mi) of the planet's cloud tops. Images were taken of the planet and a few of its moons, although their resolution was too low to discern surface detail.
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 2: 20 August 1977 [2 ...
Pioneer 11 image of Saturn.. Saturn was first visited by Pioneer 11 in September 1979. It flew within 20,000 kilometres (12,000 mi) of the top of the planet's cloud layer. Low-resolution images were acquired of the planet and a few of its moons; the resolution of the images was not good enough to discern surface featu
The third stage of Pioneer 11 is thought to be in solar orbit because its encounter with Jupiter would not have resulted in escape from the Solar System. [24] [better source needed] Pioneer 11 gained the required velocity to escape the Solar System in its subsequent encounter with Saturn. [dubious – discuss]
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 .
