were there any missions carried out as a part of its research?
Yes, "Pioneer 11" made the first flyby of Saturn in September 1979

"Pioneer 11" made the first flyby of Saturn in September 1979, when it passed within 20,000 km 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. The spacecraft also studied Saturn's rings, revealing the thin F-ring and the fact that dark gaps in the rings are bright when viewed at high phase angle (towards the Sun), meaning that they contain fine light-scattering material. In addition, "Pioneer 11" measured the temperature of Titan.
what is the atmosphere of the planet saturn The outer atmosphere of Saturn contains 96.3% molecular hydrogen and 3.25% helium by volume how are rings formed? They are composed predominantly of water ice, with trace amounts of tholin impurities and a peppered coating of approximately 7% amorphous carbon what are its physical characteristics? It is a gas giant because it is predominantly composed of hydrogen and helium, it lacks a definite surface, though it may have a solid core, its rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator does it have any moons? Yes, it has 82 known moons, 53 of which have formal names
