this is a big year for solar system exploration

We will be visiting our best-known dwarf planets, Ceres and Pluto, for the first time this year. (Ed. note: I believe they prefer to be called "little planets".)

The Dawn spacecraft arrived at Ceres today. You can read more at NASA's Dawn Blog. I've added that blog to my Recommended Reading list (in the right-hand sidebar) so it should bubble back up the list as new entries are posted.
