Voyager found that Saturn's atmosphere is almost entirely hydrogen and helium. Voyager 1 found that about 7 percent of the volume of Saturn's upper atmosphere is helium (compared with 11 percent of Jupiter's atmosphere), while almost all the rest is hydrogen. Since Saturn's internal helium abundance was expected to be the same as Jupiter's and the Sun's, the lower abundance of helium in the upper atmosphere may imply that the heavier helium may be slowly sinking through Saturn's hydrogen; that might explain the excess heat that Saturn radiates over energy it receives from the Sun. (Saturn is the only planet less dense than water. In the unlikely event that a lake could be found large enough, Saturn you could float on it!!

How many satellites have been sent to Saturn?

Four spacecraft have been sent to Saturn: Pioneer 11, Voyager 1, Voyager 2, and the Cassini-Huygens mission. Voyager 1 and Voyager 2 made flybys of Saturn while the Cassini-Huygens mission orbited the planet for over 13 years, studying its moons and rings in detail.


Why was voyager 2 sent out before voyager 1?

Voyager 2 was sent out first to allow it to take full advantage of an unusually convenient alignment of the planets allowing it to visit Uranus and Neptune as wellVoyager 1 was launched after voyager 2, but on a faster trajectory which allowed it to reach Jupiter and Saturn before voyager 2.


What was the planet that examined by Pioneer and Voyager spacecraft?

Both the Pioneer and Voyager spacecraft explored several planets in our solar system, including Jupiter, Saturn, Uranus, and Neptune. For example, Voyager 1 and 2 conducted flybys of Jupiter and Saturn, while Pioneer 10 and 11 also explored Jupiter and Saturn.


Which planet was explored by voylager 1 and 2?

Voyager 1 and 2 explored the outer planets of our solar system, primarily focusing on Jupiter and Saturn. Voyager 1 conducted a flyby of Jupiter in 1979 and Saturn in 1980, while Voyager 2 visited Jupiter in 1979, Saturn in 1981, Uranus in 1986, and Neptune in 1989. These missions provided invaluable data about the planets, their moons, and ring systems.


What are the human explorations of Saturn?

Humans have not yet explored Saturn directly. All observations of Saturn have been made through robotic spacecraft, such as the Voyager and Cassini missions. These missions have provided valuable information about Saturn's atmosphere, rings, and moons.
