I just got this message from Carolyn Porco, Team Leader for the Cassini Imaging Science Subsystem (the spacecraft's main cameras):
Time Magazine is running an Image of the Year contest, and at the moment, one of our Cassini images of Dione seen against Saturn is in 2nd place! Go to http://www.time.com/time/potw/2005_editors_choice/vote.html and help us win.
That's a cause I can get behind. I've placed my vote!
