The Cassini spacecraft examines the dark region of Senkyo on Saturn's largest moon, Titan.
Senkyo is in the center of the image, and it lies just south of the moon's equator. For an earlier view of this region, see Fascinating F Ring.
Lit terrain seen here is on the Saturn-facing side of Titan (5150 kilometers, or 3200 miles across). North on Titan is up and rotated 6 degrees to the left. The image was taken with the Cassini spacecraft narrow-angle camera on March 21, 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 994,000 kilometers (618,000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 63 degrees. Image scale is 6 kilometers (4 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. 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 and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
