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.
It's an active time in interplanetary exploration! Curiosity has begun roving Mars, and Opportunity's not wasting any time either. Dawn has just departed Vesta and begun the more than two-year cruise to Ceres. Juno is in the middle of a big deep-space maneuver, setting up next year's Earth flyby.
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.

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.

Dawn is beginning its departure from Vesta, spiraling upward from its low-altitude mapping orbit to a higher one from which it will map north polar terrain not visible during the earlier mapping orbit.
Marc Rayman's monthly check-in with the Dawn mission describes the achievements of the spacecraft in its Low-Altitude Mapping Orbit (including near-global high-resolution imaging!) and explains what's next.

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.
Last week when I joined the new weekly Space Hangout (a webcast video conference call of sorts), I realized I would need a 3D model of Dawn in order to explain what's going on with the mission right now.
