Cassini gazes at several albedo features on Saturn's largest moon, Titan.

Left to right are four dark regions: Fensal, Aztlan, Aaru and a part of Senkyo. The bright area Quivira lies near the center of the image, separating Fensal and Aztlan. This view looks toward the Saturn-facing side of Titan (5150 kilometers, 3200 miles across). North on Titan is up and rotated 24 degrees to the right.

The image was taken with the Cassini spacecraft narrow-angle camera on June 25, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers. The view was obtained at a distance of approximately 1.3 million kilometers (808,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 12 degrees. Image scale is 8 kilometers (5 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.
