Question
1. If you put your hand in a “lava” flow on Titan you would __________ it.
2. Saturn is a big giant gas ball, but actually it’s a big giant ball of ___________ .
3. Saturn is big enough to swallow _____ Earths, but as the least dense planet, it would __________ in water.
4. Saturn’s cloud tops go around about every _____ hours.
5. The rings of Saturn are extremely thin, they are no thicker than about one to two __________
in a modern building.
6. What laboratory controlled the Cassini spacecraft (and most spacecraft for that matter)?
The ______ _______________ Laboratory.
8. The ring particles range from big boulders the size of small ____________ buildings down to
the finest dust particles, all orbiting like crazy around Saturn at 20 to 40 ____________ mph.
While the particles are moving very fast, relative to each other, they are moving very_______.
9. The ring system is wide, in diameter about equal to the distance between the ________ and
the ________.
10. Shadows of features at “equinox” showed that the rings are not completely flat, they are
__________ dimensional.
11. Saturn’s surface looks rather calm and bland when in fact it is actually roiling and seething.
The apparently peaceful appearance is due to a haze of high level ________________ in the
atmosphere.
12. By looking deep into Saturn at infrared wavelengths, it was found that winds on Saturn move
at close to _____ miles per hour, near the speed of sound in the planet’s atmosphere, and
faster than the winds on Jupiter. __________ as much heat comes out of Saturn’s interior
than it receives from the Sun which leads to its dynamic atmosphere.
13. From summer to winter seasons on Saturn, the rings alternately block ___________ on the
northern and then the southern hemisphere, resulting in dramatic atmospheric changes.
14. Enceladus, a bright icy ball, hides within Saturn’s diffuse ___ ring.
16. Cassini observed geysers spewing out particles of ______ into space.
17. Cassini flew very close to Enceladus, with heights as low as _____ miles above the surface.
18. Cassini sampled the geyser plumes and found they contained methane, nitrogen, ammonia,
and organic molecules, which collectively could be called an organic ____________ soup.
20. The Huygens probe landed on the surface of icy cold Titan in a region with cobbled stones, a
stream _____ where liquid once flowed, liquid methane.
21. A proposed future mission to Titan depicts how a ___________ would provide an ideal way
to float across the surface of the moon.
22. The question about the organic molecules found on Enceladus is are they _______________
in origin.
23. JPL ended Cassini’s mission in 2017 by crashing it into _____________ .
Explanation / Answer
1. As thw volcanoes (also known as cryovolcanoes) in Titan spew ice lavas, so if we put our hand in it, our hands will get freezed.
2. Saturn is a big giant gas ball, but actually its a big giant ball of hydrogen and helium. Mostly these two gases comprises Saturn.
3. Saturn is large enough to swallow 764 earths, if it were hollow. But as it is less dense because it contains mainly gases, so it will float in water.
4. The question is not clear ,so I am answering the next question.
5. The rings of Saturn are extremely thin, but they are not thicker than one or two stories of a mordern building. The rings have a minimum thickness of 10 cm and a maximum of 1km.
