There have never been, nor will there ever be, Astronauts who land on Saturn. The gravity is too great, the air pressures are too high and the atmosphere is toxic to human life.
A human would be crushed by his/her own weight given the gravity on Saturn.
A human could not tolerate the atmospheric pressures on Saturn.
A human could not endure the gasses in Saturn's atmosphere.

The Saturn V
Since Saturn is a gas giant, there is no solid surface, making it impossible for astronauts to land a spacecraft. It may be possible to fly into its atmosphere, however this probably will not happen in the near future.
The Saturn V (Saturn five) rocket was used to launch the astronauts into space.The project was named the Apollo missions.Neil Armstrong was on Apollo 11 which was the first mission to actually land on the Moon.
Saturn V, a 3 stage rocket.
Astronauts have travelled to lots of places in space like Neil Armstrong and Buzz Aldrin went to the moon and other astronauts have gone to lots of other moons like some of Saturn's moons also astronauts have been to the international space station.
The rocket chosen for the Apollo mission was the Saturn 5.
The name of the rocket was the "Saturn V" It was a 3 stage rocket
Apollo 3 was an unmanned test of the Saturn booster
Pioneer 11 carried out the first flyby of Saturn in September 1979, when it passed within 20,000 km of the planet. This was followed by a visit of Voyager I (1980) and Cassini-Huygens space probe (2004).
Only America
The atmosphere of these planets is not suitable for human exploration. Gases and extreme pressure would instantaneously kill astronauts. Funding and the distance to the gaseous would also be reasons we have not visited Jupiter or Saturn.
