It looks like the rover team thinks Concepcion is pretty enough (in both aesthetic and a scientific senses) to be worthy of the full-color Pancam panorama treatment; color frames started arriving on Earth over the weekend.

There were many, many treats waiting on the Cassini raw images website this morning. Yesterday, Cassini traversed the G ring, taking photos all the way.

The January 1, 2010 Cassini imaging data release includes everything acquired by Cassini from January 1 to March 30, 2009 in all its high-quality glory.

It's been the second most popular question I get from readers:

This description of asteroid 2867 Steins is based upon an article published in the January 8, 2010 issue of Science by H. Uwe Keller and numerous coauthors and on a related press release.
