It's fantastic to see the continuing discovery of more than "dead cold rocks" out in the solar system. I'm still feeling stunned about Pluto a year later. Ceres looks interesting (shiny sodium carbonate, and it's apparently not aliens :-)), and it still feels like an ion drive is a sci fi idea, instead it is real.
As someone with not much planetary science exposure, what is the explanation why these other smaller bodies in the solar system like Ceres seem to have more interesting variation and more carbon, possible volatiles, than the moon?
