Exploring Saturn With Cassini
Cassini Mission Project Scientist Linda Spilker returns with the latest discoveries at the beautiful ringed planet, its moons and its rings. Emily Lakdawalla has assembled a crazy animation of distant Earth from a long dormant but just reawakened space camera.

A family of accomplished astronomers provides the answer to this week’s space trivia contest in our What’s Up segment, along with a new opportunity to win OK Go swag.
