The moons Mimas and Pandora join bright B ring spokes in this Cassini-captured scene.

Pandora (81 kilometers, 50 miles across) orbits just outside the thin F ring. Larger Mimas (396 kilometers, 246 miles across) can be seen on the left. To learn more about spokes, see PIA11144.

This view looks toward the northern, sunlit side of the rings from about 12 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Aug. 30, 2009. The view was acquired at a distance of approximately 1.8 million kilometers (1.1 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 80 degrees. Image scale is 106 kilometers (66 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
