A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.
