Cassini mission?????

Question

Ok, so since the Voyager satellites visited all of the gas giant planets in our Solar System and for many years- much of our understanding of these planets and their moons came from the Voyager experiments. In the case of Jupiter, our understanding increased when the Galileo mission reached the planet in 1995. In 2004, the Cassini Mission arrived at Saturn, and although this mission is only beginning, we have already learned a great deal about Saturn.

So what are results from the Cassini mission on the planet Saturn or any of its moons. Contrast what Cassini has learned to what we knew prior to this Mission.

Describe the Huygens probe that landed on Saturn's moon Titan and briefly describe some of its findings

Answer 1

Some highlights.

Titan: It has methane or ethane lakes and rivers.

It has a liquid ocean under the crust.

It has solid water ice rocks on the surface.

It has "sand dunes" made of, i'm not sure what.

We've learned alot about it's weather.

Enceladus: Water in the geysers feed the E ring.

Rhea: Rings.

Saturn:

Weather. Aurora.  Stable hexagonal cloud pattern at the pole.

And so on.  But Cassini can't be considered just starting.  It has finished it's primary mission.  The health of the craft is great, so it's getting an extended mission.

It's not a tiny little limited mission.  It's a billion dollar plus school bus crammed to the gills with instruments.
