Due to the distance and lack of technology, there are no manned space probes for Saturn. Started in 1997, the Cassini-Huygens mission was a joint project between NASA and the European Space Agency, for the exploration of Saturn, its moons and rings. It consisted of two major elements: the Cassini orbiter and the Huygens probe. Cassini-Huygens reached Saturn in 2004, 7 years after its launch.
Cassini-Huygens was an unmanned space mission sent on a mission to the planet Saturn and its system of moons. A joint project of NASA, ESA (European Space Agency) and ASI (Italian Space Agency), it consisted of two main elements, the Cassini orbiter and the Huygens probe. Launched into space on October 15, 1997, it entered Saturn orbit on July 1, 2004 and continued in operation until September 15, 2017, studying the planet, its natural satellites, the heliosphere and testing the Theory of Relativity. Among the mission's many discoveries are potentially habitable environments on Saturn's moons, including a subsurface ocean of water on Enceladus.
With this information, we can conclude that A project that took two decades of planning and development until its launch, after an interplanetary trip of almost seven years, in which it flew over Venus and Jupiter, the spacecraft entered Saturn orbit in mid-2004.
