This mosaic from the Descent Imager/Spectral Radiometer camera on the European Space Agency's Huygens probe combines 17 image triplets, projected from an altitude of 800 meters (2,625 feet). The area covered is approximately 1,300 meters (4,265 feet) across (north at the top of the image). The smallest visible objects visible are less than five meters (16 feet) across, and the dark channels are 30 to 40 meters (98 to 131 feet) wide.
The images were then stitched together using one of several projection algorithms (in this case 'gnomonic') to produce a full mosaic. The images used to construct this mosaic were taken on Jan. 14, 2005.
The Descent Imager/Spectral Radiometer is one of two NASA-funded instruments on the probe.
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 was designed, developed and assembled at JPL. The Descent Imager/Spectral team is based at the University of Arizona, Tucson, Ariz.
