<h1>PIA00028:  Dione Mosaic</h1><div class="PIA00028" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">Many impact craters -- the record of the collision of cosmic debris -- are shown in this Voyager 1 mosaic of Saturn's moon Dione. The largest crater is less than 100 kilometers (62 miles) in diameter and shows a well-developed central peak. Bright rays represent material ejected from other impact craters. Sinuous valleys probably formed by faults break the moon's icy crust. Images in this mosaic were taken from a range of 162,000 kilometers (100,600 miles) on Nov. 12, 1980. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00028" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA00028:  Dione Mosaic	  sur le site de la NASA">Voir l'image 	 PIA00028:  Dione Mosaic	  sur le site de la NASA.</a></div>

Bright radiating patterns probably represent debris rays thrown out of impact craters; other bright areas may be topographic ridges and valleys. Also visible are irregular valleys that represent old fault troughs degraded by impacts. The center of the frame is at 26 degrees south latitude on the Saturn-facing hemisphere. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA01366" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA01366:  The Saturnian moon Dione	  sur le site de la NASA">Voir l'image 	 PIA01366:  The Saturnian moon Dione	  sur le site de la NASA.</a></div>

Light and dark patches are visible on the moon's surface, reminiscent of features seen on Jupiter's satellite Ganymede during Voyagers's Jupiter encounter last year. The bright spots may be rays emanating from impact craters on Dione's surface. Dione is about 1,110 kilometers in diameter, about one-third the size of Earth's Moon. The smallest detail seen in this image is about 78 kilometers (48 miles) across. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA01373" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA01373:  Saturn's satellite Dione	  sur le site de la NASA">Voir l'image 	 PIA01373:  Saturn's satellite Dione	  sur le site de la NASA.</a></div>

There is a difference in character between its leading and trailing hemispheres; the trailing side, seen on the left in this image, shows a pattern of bright wispy streaks against a darker background<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA02244" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA02244:  Dione	  sur le site de la NASA">Voir l'image 	 PIA02244:  Dione	  sur le site de la NASA.</a></div>

<h1>PIA02265:  Dione - circular impact craters</h1><div class="PIA02265" lang="en" style="width:516px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">Circular impact craters up to about 100 kilometers (60 miles) in diameter are seen in this view of Saturn's icy moon Dione. The image was taken by Voyager 1 from a range of 790,000 kilometers (500,000 miles) at 2:20 a.m. PST on November 12. Bright, wispy markings form complex arcuate patterns on the surface. These markings are slightly brighter than the brightest features seen by Voyager on Jupiter's moons, suggesting that they are surface frost deposits. The patterns of the bright bands hint at an origin due to internal geologic activity, but the resolution is not yet sufficient to prove or disprove this idea. Dione's diameter is only 1100 kilometers (700 miles), much smaller than any of Jupiter's icy moons. It thus belongs to a class of small, icy objects never observed before the Voyager I Saturn encounter. The view here is of the face which trails in orbit. The Voyager Project is managed by the Jet Propulsion Laboratory for NASA.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA02265" onclick="window.open(this.href); return false;" title="Voir l'image 	 PIA02265:  Dione - circular impact craters	  sur le site de la NASA">Voir l'image 	 PIA02265:  Dione - circular impact craters	  sur le site de la NASA.</a></div>

The contrast in the version at the right has been greatly enhanced to show the side of Dione lit faintly by reflected light from Saturn. A similar phenomenon can be seen from Earth, when the Moon's dark side is visible due to "earthshine." The crater at the top of the image appears to have a sunlit central peak in the enhanced view -- a common characteristic of craters on Dione as seen in Voyager images. Slight variations in brightness on the moon's dark side hint at the bright curved linear streaks, seen by Voyager. These streaks are thought to be deposits of water ice.</p><p>The image was taken with the Cassini spacecraft narrow angle camera on July 2, 2004, from a distance of about 1.4 million kilometers (860,000 thousand miles) from Dione, at a Sun-Dione-spacecraft, or phase angle of about 119 degrees. The image scale is 8 kilometers (5 miles) per pixel. Dione's diameter is 1,118 kilometers (695 miles) across. The images have been magnified by a factor of two to aid visibility.</p><p>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 Office of Space Science, Washington, D.C.

This natural color view shows the moon has strong variations in brightness across its surface, but a remarkable lack of color, compared to the warm hues of Saturn's atmosphere. Several oval-shaped storms are present in the planet's atmosphere, along with ripples and waves in the cloud bands.</p><p>The images used to create this view were obtained with the Cassini spacecraft wide-angle camera at a distance of approximately 603,000 kilometers (375,000 miles) from Dione through a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The Sun-Dione-spacecraft, or phase, angle is 34 degrees.
