They are primitive un-evolved bodies, so by studying these bodies we can learn more about how the solar system came to be in a way that's not otherwise possible.

We're going to understand that there is life on other bodies in the solar system.

We did this mission to collect the most primitive materials we could in the solar system. We went to a comet that formed at the edge of the solar system, far from the sun under very cold conditions. We're confident that it was made out of the initial building blocks of our solar system.

We believe they hold the most primitive materials in the solar system and that they played a role in shaping some of the planets, but we really have more ideas about comets than facts.

The solar system is completely wide open. Almost anywhere we go, I'm sure we would learn a lot.
