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!

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

This morning while driving to work I heard a terrific story about Curiosity on National Public Radio from Joe Palca, NPR's science correspondent. It was a great story despite the fact that it contained virtually no news.
