As Dawn continues thrusting toward Ceres, Marc takes a look back at the intrepid spacecraft's discoveries.

As Dawn treks onward to Ceres, its path will cross within a few degrees of the moon as seen from Earth on Jan. 21–22.
My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.
A few days ago, the Dawn mission finally published their archival data. During the year of delay I often looked with anticipation to the Planetary Data System to check whether or not images were there, and I am delighted that they are finally available. Was the wait worth it? Definitely!
Planetary Radio: A Dawn Mission Update
And a Video Tour of Marc Rayman's Space Collection

A Planetary Radio status report from the Dawn mission's Marc Rayman, accompanied by a fascinating video tour of Marc's at-home collection of space information and memorabilia.
After a false start earlier this year, the first chunk of Dawn Framing Camera data from Vesta has finally made it to the Planetary Data System. As a first step to understanding the data set, I've built some index pages to these cool images.
Dawn's last images of Vesta peek into previously shadowy north polar territory. As the spacecraft leaves Vesta behind, its science team requests help from the public.
I think my favorite features on Vesta are its streaky craters. Today's image release shows one of the streakiest: Aelia, a little crater on the flank of a larger one, near Vesta's equator.

I made myself a cheat sheet to many of Vesta's distinctive-looking craters, and also wrote down a list of the major dates in the timeline of Dawn's exploration of Vesta.

On June 30, Dawn stopped thrusting for a full Vestian day -- five hours and 20 minutes -- and just watched the asteroid rotate. But unlike the previous observations, they used all of Dawn's color filters to acquire the best-ever color photos of the lumpy world.
