Voyager 2 found that at the highest levels (7 kilopascals pressure) Saturn's temperature was 70 K (−203 °C) (i.e. 70 degrees above absolute zero), while at the deepest levels measured (120 kilopascals) the temperature increased to 143 K (−130 °C). The north pole was found to be 10 K cooler, although this may be seasonal. Unfortunately ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The first human being to reach space (defined as an altitude of over 100 km) and to orbit Earth was Yuri Gagarin, a Soviet cosmonaut who was launched in Vostok 1 on April 12, 1961. The first human to walk on the surface of another Solar System body was Neil Armstrong , who stepped onto the Moon on July 21, 1969 during the Apollo 11 mission ...
1979 – Pioneer 11 flies by Saturn, providing the first ever closeup images of the planet and its rings. It discovers the planet's F ring and determines that its moon Titan has a thick atmosphere. [199] 1979 – Goldreich and Tremaine postulate that Saturn's F ring is maintained by shepherd moons, a prediction that would be confirmed by ...

So maybe it’s best we leave Saturn exploration to uncrewed probes after all. In 2017, NASA’s Cassini probe sent us our closest view of Saturn to date. If you wanted to take a closer look at ...
