This video highlights Dawn's top accomplishments during its orbit around the giant asteroid Vesta.

Have you ever seen a meteorite streaking across the sky? If so, you may very well have seen part of the asteroid, Vesta!

The most prominent jets of vapor and icy particles emerging from the south polar terrain of Saturn’s moon Enceladus are shown here in graphical form in a movie clip of a “rotating” Enceladus.

Keeping a close watch on the outer portion of Saturn's B ring, NASA's Cassini spacecraft records the complex inward and outward movement of the edge of the ring.

This audio clip was created from radio signals received by the radio and plasma wave science instrument on the Cassini spacecraft.
