View from Titan's Surface

Images from the European Space Agency's Huygens probe descent imager/spectral radiometer side-looking imager and from the medium resolution imager, acquired after landing, were merged to produce this image. The horizon's position implies a pitch of the imager/spectral radiometer, nose-upward, by 1 to 2 degrees with no measurable roll. "Stones" in the foreground are 4 to 6 inches (10 to 15 centimeters) in size, presumably made of water ice, and these lie on a darker, finer-grained substrate. A region with a relatively low number of rocks lies between clusters of rocks in the foreground and the background and matches the general orientation of channel-like features in the panorama of PIA06439). The scene evokes the possibility of a dry lakebed. The Huygens probe was delivered to Saturn's moon Titan by the Cassini spacecraft, which is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif. NASA supplied two instruments on the probe, the descent imager/spectral radiometer and the gas chromatograph mass spectrometer. http://photojournal.jpl.nasa.gov/catalog/PIA06440
