CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Two Moons, One Picture

The orbits of Dione and Titan bring them together in one frame in this distant glimpse from Cassini.

Light and dark areas on Dione (1123 kilometers, 698 miles across), at the top of the frame, hint at that moon's fractured surface. Through the hazy atmosphere of Titan (5150 kilometers, 3200 miles across) at the bottom, the dark region of Senkyo is visible.

This view looks toward the Saturn-facing side of Titan and the leading hemisphere of Dione. North on Titan is up and rotated 3 degrees to the left. The image was taken with the Cassini spacecraft wide-angle camera on Jan. 28, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 939 nanometers.

The view was acquired at a distance of approximately 2.3 million kilometers (1.4 million miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 44 degrees. Image scale is 140 kilometers (90 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.
