For this evening's Planetary Radio Live event, Mat Kaplan asked me to do a presentation of some favorite space images.

Posted by Emily Lakdawalla on 2012/04/04 12:15 CDT

In the last few days as it's rounded periapsis in its current orbit of Saturn, Cassini has taken a lot of great photos of Saturn's moons.
