This false-color image shows that some of the linear features on Enceladus have a slightly different color from their surroundings. Different colors of ice may be caused by varying compositions or varying ice crystal sizes. Either of which can indicate different formation mechanisms or different ages. Enceladus is 505 kilometers (314 miles) across.</p><p>The new view shows some of the smooth plains noted in NASA's Voyager spacecraft images and earlier Cassini images. At about the seven o'clock position are interwoven linear patterns that are reminiscent of the wispy-terrain features on two of Saturn's other moons, Dione and Rhea.</p><p>Imaging scientists are not sure whether these brighter markings are evidence for contamination of the ice in the linear features by some other material. Analysis of high resolution images of Enceladus should also show whether, like the surprising terrain seen on Dione, the "wisps" are curvilinear fractures that are not quite resolved at this scale.</p><p>This false color view combines images obtained using filters sensitive to ultraviolet, polarized green and infrared light. The images were obtained with the Cassini spacecraft narrow angle camera on Feb. 16, 2005, at distances ranging from 179,727 to 179,601 kilometers (111,677 to 111,599 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 22 degrees. Resolution in the image is about 1 kilometer (0.6 mile) per pixel.</p><p>The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

The area is 70 kilometer by 84 kilometer (43 mile by 52 miles).</p><p>The image shows a variety of tectonic features that attest to Enceladus' dynamic geological history. At the top of the image is a relatively fresh-looking crevasse system with individual fractures more than a kilometer wide. The crevasse system cross-cuts a complex northeast-to-southwest-trending system of older faults. A 12-kilometer-wide (7-mile-wide) band of crudely aligned, chevron-shaped features runs down the center of the image.</p><p>Among the most intriguing features in this view are a series of dark, small spots, 125 to 750 meters (400 to 2,500 feet) in diameter. The dark spots often seem to be aligned in chains parallel to narrow fractures. The contrast of the dark features with the surrounding bright terrain suggests that they may be compositionally distinct, but their origin is a new mystery.</p><p>The orientation of the image is such that north is approximately 30 degrees clockwise from the bottom of the frame.

More than 20 years ago, NASA's Voyager spacecraft gave hints of a surface cut by tectonic features, and subsequent images of other icy moons have revealed many different ways that stresses have acted on icy moon crusts.</p><p>The new close-up images of Enceladus, which has a diameter of 505 kilometers (314 miles), show some familiar-looking features and others that are brand new. The work required to unravel their origins, their formation sequence, and the implications for the evolution of icy solar system bodies is just beginning.</p><p>Voyager images of Enceladus, which were obtained at much poorer spatial resolution, showed terrains like those seen here. They were called "smooth plains" because they appeared to exhibit little topographic relief. However, Cassini has now viewed these terrains at almost 10 times better resolution. The new images reveal very complex systems of fractures, resurfaced terrain, and in some cases, topographic relief greater than several hundred meters. </p><p>Many styles of fracturing are evident in this mosaic. Extending downward from the top center of the mosaic for hundreds of kilometers is a broad belt of complex, interwoven fractures. A huge rift 5 kilometers (3 miles)-wide dissects this belt and extends into several older-looking, distinct regions or "cells" of terrain that themselves exhibit distinct fracture patterns.<p>Because Cassini flew rapidly past Enceladus, the right-side images were taken from a slightly different perspective than the left, and are delineated by the white box.</p><p>The mosaic covers longitudes from about 254 west to 296 west and latitudes from 60 south to the equator.</p><p>The images were taken in visible light on Feb. 17, 2005, at distances ranging from of 26,140 to 17,434 kilometers (16,243 to 10,833 miles) from Enceladus and at Sun-Enceladus-spacecraft, or phase, angles ranging from 27 to 29 degrees. Pixel scale in the left-side image is 150 meters (492 feet) per pixel; in the right-side (white box) image, scale is 105 meters (344 feet) per pixel. The image has been contrast-enhanced to aid visibility. </p><p>The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

Scientists can use the relationships between different features to determine the order in which they formed, thereby unraveling the moon's past. For example, almost all the craters in this mosaic have fractures running through their rims and floors, indicating that the craters formed first. This means that Enceladus has been geologically active relatively recently, especially compared to some of its neighbors in the Saturn system.</p><p>There is an impressive variety of fractures visible here--from the wide east-west rifts near the upper left of the mosaic to the very fine north-south fractures in the center (which are approximately 100 to 400 meters, or 330 to 1,300 feet, across). Due to the complexity of this terrain, the task of unraveling Enceladus' history promises to be a worthy challenge for planetary scientists.</p><p>The images in this mosaic were taken on March 9, 2005, in visible green light with the Cassini spacecraft narrow-angle camera at distances ranging from approximately 13,000 to 5,200 kilometers (8,000 to 3,200 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle ranging from 44 to 38 degrees.

The relatively dense accumulation of impact craters implies that this terrain is among the oldest on the moon's surface. Near the bottom of the picture is a crater 20 kilometers wide (12-mile) with a prominent dome-shaped structure in its center. The entire area is transected by a complex web of fractures and faults; some are as narrow as a few hundred meters, others as wide as 5 kilometers (3 miles).</p><p>The rims and interiors of many craters seem to be sliced by a pervasive system of narrow, parallel grooves into slabs or lanes that typically are a kilometer (about a half-mile) in width. The widely varied appearances of fractures in this region attest to the fact that the surface of Enceladus has been shaped by a long history of intense tectonic activity. The oldest fractures are characterized by a soft, muted appearance and are overprinted by numerous, superimposed impact craters. More recent fractures exhibit topographic relief that is relatively "crisp" in appearance, and they appear to slice through pre-existing impact craters and older fractures.</p><p>On the right side of the image is a conspicuous and twisted network of ridges and troughs forming a distinct tectonic region on Enceladus. The paucity of craters and the sharp appearance of the topography in this area indicate that this is a relatively young terrain on Enceladus.</p><p>This view is a composite of images taken using filters sensitive to ultraviolet (centered at 338 nanometers), green (centered at 568 nanometers), and near-infrared (centered at 930 nanometers) light, and has been processed to accentuate subtle color differences. The uppermost surface of these terrains has a relatively uniform grayish color in this picture, suggesting that it is covered with materials of homogeneous composition and grain size. However, many of the fractures reveal a distinctly different color (represented by pale-bluish tones in this false-color image) than the typical surface materials. These "colored" fractures seem to penetrate down to a material that is texturally or compositionally different than most of the material at the surface.</p><p>One possibility is that the walls of the fractures expose outcrops of solid ice, or ice with different grain-sizes compared to powdery surface materials that blanket flat-lying surfaces. It is also possible that the color identifies some compositional difference between buried ice and ice at the surface. The distinct coloration of "youthful" fracture walls are nearly absent in the oldest fractures. This is consistent with the possibility that the older fractures are covered with a drape of particulate material which mantles nearly all the oldest features on the satellite. </p><p>In the early 1980's, NASA's Voyager mission to the outer planets revealed a strikingly similar arrangement of terrains on Miranda, an icy moon of Uranus (see <a href="/catalog/PIA00141">PIA00141</a>). Miranda is 470-kilometers-wide (290 miles), nearly as large as Enceladus (504 kilometers, or 313 miles wide). The similarities in size and tectonic history on these objects may suggest that remarkably similar physical processes have controlled the separate geological evolutions of these bodies.</p><p>The images that comprise this mosaic were obtained during Cassini's closest approach to Enceladus on March 9, 2005. The images was taken in visible green light with the Cassini spacecraft narrow-angle camera at a distance of approximately 29,000 kilometers (18,000 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 46 degrees.

To the right of the boundary is older, cratered terrain - a region peppered with craters ranging from 10 kilometers (6 miles) in diameter, down craters near the limit of resolution. The region is believed to be old because it has accumulated a relatively high density of impact craters over time and the topography is soft and muted, suggesting that it is covered by a layer of particulate materials. The cratered terrain is cut crosswise by numerous faults and fractures ranging in width from hundreds of meters to a few kilometers.</p><p>On the left side of the scene are grooved, icy plains. This broad, relatively flat region is scored by an extensive band of parallel grooves that appear to subdivide the surface into narrow lanes approximately 1 kilometer or half a mile wide. The low abundance of impact craters and crisp relief on topographic features here imply that this region is geologically much younger than the cratered terrain at the right.</p><p>This view is a composite of images taken using filters sensitive to ultraviolet (centered at 338 nanometers), green (centered at 568 nanometers), and near-infrared (centered at 930 nanometers) light, and has been processed to accentuate subtle color differences. </p><p>The uppermost surface of these terrains has a relatively uniform pinkish cast in this picture, suggesting that it is covered with materials of homogeneous composition and grain size.

The prominent crater at the top contains a central, domelike structure more than 11 kilometers (7 miles) in diameter.

The image was also processed to enhance contrast while avoid saturation of the brightest parts of the scene. Hence, the surface does not have the brightness of fresh snow, as it would appear to the human eye.</p><p>The Sun is illuminating the surface from the left of the image and at a low enough angle that the rugged ridge crests near upper left (which range in height from 50 to 100 meters or 164 to 328 feet) cast dramatic shadows, as at the top center of the image. The origin of the very small dark spots in the ridged terrain is uncertain. They could be shadows cast by small, building-sized outcrops (approximately 60-meter or 200-feett high) just at the limits of resolution. </p><p>Intriguingly, the craters in this scene are quite subdued, indicating that they have been degraded by some process. The craters clearly predate most of the fractures.</p><p>Additionally, multiple sets of fractures running in different directions can be seen. One set above the lower right has a gentle appearance similar to that of the craters. In contrast, the fractures running along the left are fresher. By studying differences in the morphology and patterns of the fractures, scientists will be able to learn about Enceladus' crust and how it, and geologic processes acting within it, have changed over time.</p><p>Images obtained using red, green and blue spectral filters were combined to create this view. The image was taken with the Cassini spacecraft narrow-angle camera at a distance of approximately 5,200 kilometers (3,200 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 39 degrees.

The craters here are subdued, as seen elsewhere on Enceladus, and most, but not all, are older than the fractures. Fracturing has occurred at a wide variety of scales, from the wide rift running through the center of the image to much narrower sets of shorter fractures that crosscut the craters (and each other) to the left.</p><p>The anaglyph has been rotated so that north on Enceladus is up. </p><p>This region is a transition from cratered to wrinkled terrain. Westward (left) of the central rift that divides the two regions are relatively parallel grooves and ridges that are reminiscent of terrain on Jupiter's large moon Ganymede. Very few craters are seen in this area of Enceladus. Eastward (right) of the large rift the terrain becomes more cratered, although the craters are quite degraded (meaning soft and shallow in appearance).</p><p>A prominent fracture runs north-south to the center of the image, then turns sharply to the southwest, cutting across cratered terrain, the large rift, and the grooved terrain.

The craters here are subdued, as seen elsewhere on Enceladus, and most, but not all, are older than the fractures. Fracturing has occurred at a wide variety of scales, from the wide rift running through the center of the image to much narrower sets of shorter fractures that crosscut the craters (and each other) to the left.</p><p>The image has been rotated so that north on Enceladus is up.</p><p>This region is a transition from cratered to wrinkled terrain. Westward (left) of the central rift that divides the two regions are relatively parallel grooves and ridges that are reminiscent of terrain on Jupiter's large moon Ganymede. Very few craters are seen in this area of Enceladus. Eastward (right) of the large rift the terrain becomes more cratered, although the craters are quite degraded (meaning soft and shallow in appearance).</p><p>A prominent fracture runs north-south to the center of the image, then turns sharply to the southwest, cutting across cratered terrain, the large rift, and the grooved terrain. This behavior signifies that it is one of the youngest features in this image.</p><p>The image was taken in visible light with the narrow angle camera from a distance of about 14,000 kilometers (8,800 miles) and from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 44 degrees.

This observation indicates that there have been multiple episodes of activity on Enceladus spread over some fraction of its history. The resurfacing mechanism appears to be dominated by tectonic fracturing. As of yet, there is no clear evidence for release of liquid to the surface in either icy volcanic flows or geysers.</p><p>The south polar region (seen here at the lower right) has a distinctive tectonic structure that sets it apart from the rest of the satellite. Its outer boundary is marked by a series of pronounced tectonic "gashes" that form a hoop-like boundary, near 60 degrees south latitude.

The two images were acquired at an altitude of approximately 208 kilometers (129 miles), as Cassini made its closest approach yet to Enceladus.</p><p>The wide-angle view shows what appears to be a geologically youthful, tectonically fractured terrain.</p><p>In the narrow-angle view, some smearing of the image due to spacecraft motion is apparent. Both of these views were acquired as Enceladus raced past Cassini's field of view near the time of closest approach. At the time, the imaging cameras were pointed close to the moon's limb (edge), rather than directly below the spacecraft. This allowed for less 'motion blur' than would have been apparent had the cameras pointed straight down. Thus, the terrain imaged here was actually at a distance of 319 kilometers (198 miles) from Cassini.</p><p>At the fine scale afforded by the Cassini spacecraft narrow-angle view, the surface is dominated by ice blocks between 10 and 100 meters (33 and 330 feet) across. The origin of these icy boulders is enigmatic. Scientists are interested in studying the sizes and numbers of the blocks in this bizarre scene, and in understanding whether terrain covered with boulders is common on Enceladus.</p><p>The images in this comparison view are available individually (see <a href="/catalog/PIA06251">PIA06251</a> and <a href="/catalog/PIA06252">PIA06252</a>).</p><p>Image scale is about 4 meters (13 feet) per pixel in the narrow-angle image and about 37 meters (121 feet) per pixel in the wide-angle image.

These views have been combined into this exciting movie sequence. The movie provides a stunning, up-close look at what is surely one of the youngest surfaces in the Saturn system.</p><p>From afar, Enceladus exhibits a bizarre mixture of softened craters and complex, fractured terrains. The movie zooms in on the southern polar terrains and closes in on one of the tectonic stripes that characterize this region which is essentially free of sizeable impact scars.</p><p>The bright oblong area seen during the zoom is an intermediate resolution image from near the time of closest approach that has been melded into the lower resolution mosaic, and artificially brightened.</p><p>The movie ends on the highest resolution image acquired by Cassini which reveals a surface dominated by ice blocks between 10 and 100 meters (33 and 330 feet) across, lying in a region that is unusual in its lack of the very fine-grained frost that seems to cover the rest of Enceladus.</p><p>The lack of frost and the absence of craters are indicators of a youthful surface.</p><p>The initial image in the movie is a large mosaic of 21 narrow-angle camera images that have been arranged to provide a full-disk view of the anti-Saturn hemisphere on Enceladus. This mosaic is a false-color view that includes images taken at wavelengths from the ultraviolet to the infrared portion of the spectrum, and is similar to another, lower resolution false-color view obtained during the flyby (see <a href="/catalog/PIA06249">PIA06249</a>). In false-color, many long fractures on Enceladus exhibit a pronounced difference in color (represented here in blue) from the surrounding terrain.</p><p>A leading explanation for the difference in color is that the walls of the fractures expose outcrops of coarse-grained ice that are free of the powdery surface materials that mantle flat-lying surfaces.</p><p>The original images in the false-color mosaic range in resolution from 350 to 67 meters (1,148 to 220 feet) per pixel and were taken from distances ranging from 61,300 to 11,100 kilometers (38,090 to 6,897 miles) from Enceladus. The mosaic is also available separately (see <a href="/catalog/PIA06254">PIA06254</a>).</p><p>Image scale is about 37 meters (121 feet) per pixel in the wide-angle camera image and about 4 meters (13 feet) per pixel in the narrow-angle image (see PIA06250 for these images). Both of these ultra-high resolution views were acquired from an altitude of approximately 208 kilometers (129 miles) above Enceladus as the spacecraft near the time of closest approach during the flyby.</p><p>The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.
