This image compares streaked terrain on Titan and Mars. At left is an image from Cassini of the region where the Huygens probe is expected to land. At right is a picture from NASA's Viking 1 orbiter, showing streaks on Mars caused by winds blowing from right to left. The streaks at the Huygens landing site were formed by some kind of fluid, possibly wind, moving from the upper left to lower right (west to east).

The Cassini image was taken on Oct. 26, 2004, by the spacecraft's imaging science subsystem using near-infrared filters. North is 45 degrees to the right of vertical. The scale of this image is 0.83 kilometers (.52 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 Cassini-Huygens 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 team is based at the Space Science Institute, Boulder, Colo.
