Zoom in on a HUGE lunar bullseye

Wow!!
Amazing photo taken by Cassini of Saturn's moon Rhea. The smaller moon below it is Epimetheus. It appears smaller because the distance between each other is the approximate distance between Earth and our moon. Cassini was about 750,000 miles from Rhea when the photo was taken -- and Epimetheus was 990,000 miles away from Cassini.
This is amazing! The HiRISE camera on the Mars Reconnaissance Orbiter caught another avalanche on Mars.
