"There are many questions scientists have about Iapetus. For example, there's the equatorial ridge. Scientists want to find out how it was made...but more about that later. Oh, and what created the surface of Iapetus? How has it evolved after that? Finally, how does it interact with Saturn? This is why I think Iapetus would be a good target for Cassini.

The equatorial ridge is ten kilometer high mountains all in a row. Scientists want to know how it was formed. They think it was made from either the collapse of one of Saturn's rings or that it was formed when the moon was first created. Or it could be neither, and something completely different. It is a mystery, but maybe Cassini could give scientists a clue.

One of the top five questions scientists want answered is: what created the surface of Iapetus? They also have lots of other questions within this one question. What physical processes were used to make the surface of Iapetus? How many? What else is there to learn about the surface of Iapetus? These are only some of the many questions about Iapetus' surface. But what created it?

How does Iapetus react with Saturn? Like the question of what created the surface, there are many questions inside one very simple one. How does Iapetus react with Saturn's magnetosphere? It's ring system? What else could Iapetus react to of Saturn's, and how would it? There are so many questions scientists have asked, and so many are unanswered.

There are so many questions and answers yet to come. It's confusing, mind boggling. Scientists want answers, and the only way they're going to get those answers is to send Cassini to Iapetus. These questions are hard, but with many operations and Cassini's observations, it is possible to solve them. The inquiries on the top five list are only the beginning of a long line of queries, and that is why Cassini needs to go to Iapetus.

Iapetus is amazing but confusing, excellent but baffling, fabulous but puzzling, fantastic but perplexing. There's the equatorial ridge with it's flummoxing cause. Or that infuriating question of how the surface of Iapetus was created. Finally, what about that vexing inquiry of how this moon interacts with Saturn. Cassini needs to go to Iapetus. Choose target one. "
