Happy Birthday Brian. I hope next year is everything you wish it to be. Thank you for your wonderful programs.
Rhea and Dione seem like dark and light fraternal twins in this Cassini spacecraft image, with each of these two Saturnian moons displaying a large crater oriented similarly in the northern hemisphere.
Rhea, on the left, is closer to the Cassini spacecraft than Dione in this view. Saturn is out-of-frame, far to the right of this view.
Awesome: The night sky in motion.
