Rhea's Pop-up Crater |
| Original Caption Released with Image |
Annotated Version Rhea's surface gains some depth in this stereo image, or anaglyph, which features the bright and geologically young-looking rayed crater on the moon's leading hemisphere. The view was created from images taken during Cassini's close encounter with Rhea (1,528 kilometers, or 949 miles across) on Aug. 30, 2007. The crater is 48 kilometers (30 miles) wide, and its rays extend several hundred kilometers outward. The rim of this crater is quite sharply defined, and there are few small craters overprinted onto it. These characteristics, along with the brightness of the crater and its rays are indicative of a feature formed relatively recently in geologic history. The hummocky floor of the crater possesses a central peak and clusters of small craters. The little craters may be secondary impact sites, formed by ejecta from the primary impact that landed in the crater, or they could have been formed by material that had broken off of the body that struck Rhea. For an even higher resolution view of this feature, see PIA07764 [ http://photojournal.jpl.nasa.gov/catalog/PIA07764 ]. This stereo image is a mosaic consisting of seven Cassini spacecraft narrow-angle camera images. The view is an orthographic projection centered on 12 degrees south latitude, 112 degrees west longitude and has a resolution of 45 meters (148 feet) per pixel. An orthographic view is most like the view seen by a distant observer looking through a telescope. North is up. The clear filter images for this stereo image were taken from distances ranging from about 17,000 kilometers (10,600 miles, for the red-colored image) to 7,500 kilometers (4,700 miles, for the blue/green-colored image) from Rhea.

| Title |
Color Across Rhea |
| Original Caption Released with Image |
Side-by-side natural color and false-color views highlight the wispy terrain on Rhea's trailing hemisphere. The extreme false color image makes it clear that the wisps -- likely networks of fractures as on Dione -- cut across older, cratered terrain. In addition, a set of thin, north-south trending lineaments (also likely fractures) is visible on the left side of both views. The natural color view was created by compositing images taken using red, green and blue spectral filters. To create the false-color view, ultraviolet, green and infrared images were combined into a single picture that isolates and maps regional color differences. This "color map" was then superimposed over a clear-filter image that preserves the relative brightness across the body. The combination of color map and brightness image shows how colors vary across the surface of Rhea. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy surface material. North on Rhea (1,528 kilometers, or 949 miles across) is up. The images were taken with the Cassini spacecraft narrow-angle camera on Jan. 17, 2007 at a distance of approximately 597,000 kilometers (371,000 miles) from Rhea.

The first artificial satellite in the Saturn system, the Cassini spacecraft, returned images of the natural moons following a successful insertion into orbit. This is an unmagnified view of the moon Rhea. With a diameter of 1,528 kilometers (950 miles) across, Rhea is Saturn's second largest moon. The Voyager spacecraft found that like Dione, Rhea has one of its hemispheres covered with bright, wispy streaks which may be water frost. This view shows a heavily cratered surface, and thus it is most likely ancient. Many of the craters visible here have central peaks. Cassini soon will look for clues to help unlock the moon's geologic history. The spacecraft is slated to fly by Rhea at a distance of only 500 kilometers (311 miles) on Nov. 26, 2005. The image was taken in visible light with the Cassini spacecraft narrow angle camera on July 2, 2004, from a distance of about 990,000 kilometers (615,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase angle of about 109 degrees.

Rhea's Wisps in Color |

Bright, wispy markings stretch across a region of darker terrain on Saturn's moon Rhea. In this extreme false-color view, the roughly north-south fractures occur within strips of material (which appear greenish here) that are a different color from the surrounding cratered landscape. To create the false-color view, ultraviolet, green and infrared images were combined into a single black and white picture that isolates and maps regional color differences. Most of the large-scale variations in brightness across the surface are removed by this process. This "color map" was then superimposed over a clear-filter image. The origin of the color differences is not yet understood, but it may be caused by subtle differences in the surface composition or grain sizes making up the icy soil. Wispy markings were seen on the trailing hemispheres of both Rhea and Dione in images taken by NASA's Voyager spacecraft, and were hypothesized by some researchers to be the result of material extruded onto the surface by ice volcanism. Cassini's earlier revelation of the braided fractures on Dione led to speculation that Rhea's wisps might also be created by fractures. This view shows terrain on the trailing hemisphere of Rhea (1,528 kilometers, or 949 miles across). North is up.

Prime Time for Rhea |
| Original Caption Released with Image |
This map of the surface of Saturn's moon, Rhea, illustrates the regions that will be imaged by Cassini during the spacecraft's close flyby of the moon on Nov. 26, 2005. At closest approach, the spacecraft is expected to pass approximately 500 kilometers (310 miles) above the moon's surface. The colored lines delineate the regions that will be imaged at differing resolutions, listed in the legend at bottom. Rhea is 1,528 kilometers (949 miles) across. The new high-resolution coverage will examine details on the anti-Saturn hemisphere of Rhea, including two large impact basins there. Cassini previously imaged terrain farther to the south of this at approximately 1 kilometer (0.6 mile) per pixel in August 2005 (see PIA07566 [ http://photojournal.jpl.nasa.gov/catalog/PIA07566 ]). Imaging scientists also hope to get a high-resolution view of a relatively young 50-kilometer-wide (30-mile) crater on the moon's leading hemisphere (see PIA06648 [ http://photojournal.jpl.nasa.gov/catalog/PIA06648 ]). Planetary scientists are interested in learning about the compositional makeup of Rhea, other than water ice, as well as the nature of the wispy streaks on the moon's trailing hemisphere. In December, 2004, Cassini revealed that similar bright, wispy markings on Dione are actually a system of braided tectonic fractures (see PIA06162 [ http://photojournal.jpl.nasa.gov/catalog/PIA06162 ]). The map was made from images obtained by both the Cassini and NASA Voyager spacecraft.

This giant mosaic reveals Saturn's icy moon Rhea in her full, crater-scarred glory. This view consists of 21 clear-filter images and is centered at 0.4 degrees south latitude, 171 degrees west longitude. The giant Tirawa impact basin is seen above and to the right of center. Tirawa, and another basin to its southwest, are both covered in impact craters, indicating they are quite ancient. The bright, approximately 40-kilometer-wide (25-mile) ray crater seen in many Cassini views of Rhea is located on the right side of this mosaic (at 12 degrees south latitude, 111 degrees west longitude). See PIA07764 [ http://photojournal.jpl.nasa.gov/catalog/PIA07764 ] for a close-up view of the eastern portion of the bright, ray crater. There are few signs of tectonic activity in this view. However, the wispy streaks on Rhea that were seen at lower resolution by NASA's Voyager and Cassini spacecraft, were beyond the western (left) limb from this perspective. In high-resolution Cassini flyby images of Dione, similar features were identified as fractures caused by extensive tectonism. Rhea is Saturn's second-largest moon, at 1,528 kilometers (949 miles) across. The images in this mosaic were taken with the Cassini spacecraft narrow-angle camera during a close flyby on Nov. 26, 2005. The images were acquired as Cassini approached the moon at distances ranging from 79,190 to 58,686 kilometers (49,206 to 36,466 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of about 19 degrees.

Color Variation Across Rhea and Dione |
| Original Caption Released with Image |
Saturn's cratered, icy moons, Rhea and Dione, come alive with vibrant color that reveals new information about their surface properties. To create these false-color views, ultraviolet, green and infrared images were combined into a single black and white picture that isolates and maps regional color differences. This "color map" was then superimposed over a clear-filter image of each moon. The combination of color map and brightness image shows how the colors vary across the moon's surface in relation to geologic features. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy soil. The Rhea view is a two-image mosaic. Images in the mosaic were acquired on Aug. 1, 2005, at a mean distance of 214,700 kilometers (133,400 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 88 degrees. Image scale is 1.3 kilometers (0.8 miles) per pixel. The mosaic shows terrain on the trailing hemisphere of Rhea (1,528 kilometers, or 949 miles across), and is centered on 42 degrees south latitude. North is up and rotated 28 degrees to the left. Images in the Dione false-color view were acquired on Aug. 1, 2005, at a mean distance of 267,600 kilometers (166,300 miles) from Dione. Image scale is 1.6 kilometers (1 mile) per pixel. The image shows terrain on the trailing hemisphere of Dione (1,126 kilometers, or 700 miles across), and is centered on 41 degrees south latitude.

Saturn's moon Rhea is an alien ice world, but in this frame-filling view it is vaguely familiar. Here, Rhea's cratered surface looks in some ways similar to our own Moon, or the planet Mercury. But make no mistake -- Rhea's icy exterior would quickly melt if this moon were brought as close to the Sun as Mercury. Rhea is 1,528 kilometers (949 miles) across. Instead, Rhea preserves a record of impacts at its post in the outer solar system. The large impact crater at the center left (near the terminator or boundary between day and night), called Izanagi, is just one of the numerous large impact basins on Rhea. This view shows principally Rhea's southern polar region, centered on 58 degrees South, 265 degrees West.

Rhea's Memory |
| Original Caption Released with Image |
The story of the solar system is written upon the faces of its many worlds, such as Saturn's icy moon Rhea, seen here in an image from Cassini. The moon's many impact craters attest to its violent beginnings and more than four billion years of subsequent history. Rhea is 1,528 kilometers (949 miles) across. Most moons in the outer solar system are icy, in contrast to the rocky inner planets and Earth's moon. When the planets and their moons first formed around our Sun, conditions were cold enough at Saturn's distance that ices could condense to form solid bodies like Rhea. Since its formation, Rhea has been battered by the leftover debris of planet building, although at a much lower rate for the past 3.8 billion years or so.

Sun-Drenched Rhea |
| Original Caption Released with Image |
Saturn's brightly sunlit moon Rhea commands the foreground in this image from Cassini. The planet's splendid rings are discernible in the background. Rhea is 1,528 kilometers (949 miles) across. The spacecraft was just above the ringplane when it acquired this image, and thus captured the darkened appearance of the dense B ring when viewed with sunlight filtered through the rings. From this perspective, bright areas in the rings are regions of low density, containing very small particles that effectively scatter light toward Cassini. North on Rhea is up and rotated about 25 degrees to the left. This view shows principally the anti-Saturn hemisphere on Rhea. The right side of Rhea is overexposed. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 18, 2005, at a distance of approximately 540,000 kilometers (340,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 110 degrees.

| Title |
Rhea in Natural Color |
| Original Caption Released with Image |
The trailing hemisphere of Saturn's moon Rhea seen here in natural color, displays bright, wispy terrain that is similar in appearance to that of Dione, another one of Saturn's moon. At this distance however, the exact nature of these wispy features remains tantalizingly out of the reach of Cassini's cameras. At this resolution, the wispy terrain on Rhea looks like a thin coating painted onto the moon's surface. Cassini images from December 2004 (see PIA06163 [ http://photojournal.jpl.nasa.gov/catalog/PIA06163 ]) revealed that, when seen at moderate resolution, Dione's wispy terrain is comprised of many long, narrow and braided fractures. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft narrow angle camera on Jan. 16, 2005, at a distance of approximately 496,500 kilometers (308,600 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 35 degrees. Resolution in the original image was about 3 kilometers (2 miles) per pixel. The image has been rotated so that north on Rhea is up. Contrast was enhanced and the image was magnified by a factor of two to aid visibility.
