 And since the earth is part of the solar system, by studying the solar system, we hope that we will learn more about how the earth got to where it is today and where it's going. We're not disappointed. This mission is exciting. Watch the behavior of these clouds the way they interact with one another. This is the most dynamic and active geologic surface in the entire solar system. Volcanic lava flows. Each of these satellites is unique. It can fit approximately 760 earths inside of Saturn. They are made up of individual small particles, perhaps something the size of a basketball. Each one of those is like a tiny satellite. You have to catch it just right when the outside freezes and the inside is still liquid. Saturn's large moon Titan has an atmosphere probably two to three times as dense as the atmosphere here on earth. An atmosphere predominantly nitrogen but with a trace of methane. Last night we had these frames come back from two billion miles away. It's difficult to explain. We're very sensitive to any dust in the rings. Expectations. Here we see a cliff 16 miles high on this fault. If you were standing here you could flip a rock off it would take nine minutes to fall to the bottom. When you generate a magnetic field of a planet briefly you do it by having an electrical current flow inside the planet. Micro seconds plus or minus one microsecond. The surprise to me was that there was anything to see at all. That's motion. That's how you study motion. Motion is the key to meteorology. It looks like we got pounded with about 300 hits per second of tiny little dust particles. And the science is pushed in in an amazing fashion. It's like fitting a jigsaw puzzle together. One of the interesting things that's kind of bizarre is the terminator region of Triton. It's gorgeous farewell to us and it's our farewell to you.
