Dione and Ghostly Titan

The surface of Saturn's moon Dione is rendered in crisp detail against a hazy, ghostly Titan.

A portion of the "wispy" terrain of Dione's trailing hemisphere can be seen on the right (see PIA12553). Also visible in this image are hints of atmospheric banding around Titan's north pole. To learn more about the northern bands, see PIA08868 and PIA08928. This view looks toward the Saturn-facing hemisphere of Dione (1123 kilometers, 698 miles across) and Titan (5150 kilometers, 3200 miles across).

The image was taken in visible blue light with the Cassini spacecraft narrow-angle camera on April 10, 2010. The view was acquired at a distance of approximately 1.8 million kilometers (1.1 million miles) from Dione and 2.7 million kilometers (1.7 million miles) from Titan. Scale in the original image was 11 kilometers (7 miles) per pixel on Dione and 16 kilometers (10 miles) on Titan. The image has been magnified by a factor of 1.5 and contrast-enhanced to aid visibility.

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.

Excellent image. I love the way the NAC comprises perspective and makes both moons so close and how both are so different; with some imagination, one could think Dione orbits Titan.

Just another example of the diverse collection of worlds in the Saturnian system. A nice blend of both science and art.

This image is a very eloquent statement on the beauty and diversity in the Saturn system. i was deeply moved.
Carolyn is right on the mark, Mercury.

Lovely, I worked on some sharpened enlargements of this & neibouring frames & are on

Shows highly geologically evolved Dione sliding in fornt of the complex rich chemistry of Titan's hazes. Quite a picture indeed.
