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.


What 3 robots went to Saturn and what year?

The three robotic missions that explored Saturn are Pioneer 11, Voyager 1, and Voyager 2. Pioneer 11 flew by Saturn in 1979, providing the first close-up images of the planet and its rings. Voyager 1 followed in 1980, offering detailed data and images, while Voyager 2 completed the trio with its flyby in 1981, further enhancing our understanding of Saturn and its moons.


What year did Voyager 1 arrive to Saturn?

Voyager 1 arrived at Saturn on November 12, 1980. This mission provided a wealth of information about Saturn's rings, moons, and atmosphere, significantly enhancing our understanding of the planet. It was the first spacecraft to visit Saturn, marking a major milestone in space exploration.


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.
