Saturn's pockmarked moon Mimas is seen chugging along in its orbit in this Cassini spacecraft image taken on Aug. 16, 2006.

Herschel, an 80 mile (130 km) wide crater on the satellite is clearly visible. The image was taken in visible light with the spacecraft's narrow-angle camera from about 137,000 miles (221,000 km) away.
