Montage of Saturn and several of its satellites, Dione, Tethys, Mimas, Enceladus, Rhea, and Titan. JPL image PIA01482: Saturn System Montage This montage of images of the Saturnian system was prepared from an assemblage of images taken by the Voyager 1 spacecraft during its Saturn encounter in November 1980. This artist's view shows Dione in the forefront, Saturn rising behind, Tethys and Mimas fading in the distance to the right, Enceladus and Rhea off Saturn's rings to the left, and Titan in its distant orbit at the top.
Saturn's inner moon Daphnis on a detailed photograph by Cassini.
This true color picture was assembled from Voyager 2 Saturn images obtained Aug. 4 [1981] from a distance of 21 million kilometers (13 million miles) on the spacecraft's approach trajectory. Three of Saturn's icy moons are evident at left. They are, in order of distance from the planet: Tethys, 1,050 km. (652 mi.) in diameter; Dione, 1,120 km. (696 mi.); and Rhea, 1,530 km. (951 mi.). The shadow of Tethys appears on Saturn's southern hemisphere. A fourth satellite, Mimas, is less evident, appearing as a bright spot a quarter-inch in in from the planet's limb about half an inch above Tethys; the shadow of Mimas appears on the planet about three-quarters of an inch directly above that of Tethys. The pastel and yellow hues on the planet reveal many contrasting bright and darker bands in both hemispheres of Saturn's weather system. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, California, United States.
Titan's atmosphere makes Saturn's largest moon look like a fuzzy orange ball in this natural color view from the Cassini spacecraft.
Titan's north polar hood is visible at the top of the image, and a faint blue haze also can be detected above the south pole at the bottom of this view.
This view looks toward the anti-Saturn side of Titan (3,200 miles, or 5,150 kilometers across). North is up. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini spacecraft wide-angle camera on Jan. 30, 2012 at a distance of approximately 119,000 miles (191,000 kilometers) from Titan. Image scale is 7 miles (11 kilometers) per pixel.This raw, unprocessed image of Prometheus was taken by Cassini on Dec. 26, 2009.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 26, 2009 at a distance of approximately 79,000 kilometers (49,000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 18 degrees. Image scale is 474 meters (1,556 feet) per pixel.
The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C.

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 impact basin Tirawa is seen above and to the right of center. Tirawa, and the even larger basin Mamaldi 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 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. Image scale in the mosaic is 354 meters (1,161 feet) per pixel.

Saturn Cassini-Huygens (NASA)
Instrument: Imaging Science Subsystem - Narrow Angle
Saturn's peaceful beauty invites the Cassini spacecraft for a closer look in this natural color view, taken during the spacecraft's approach to the planet. By this point in the approach sequence, Saturn was large enough that two narrow angle camera images were required to capture an end-to-end view of the planet, its delicate rings and several of its icy moons. The composite is made entire from these two images.
Moons visible in this mosaic: Epimetheus (116 kilometers, 72 miles across), Pandora (84 kilometers, 52 miles across) and Mimas (398 kilometers, 247 miles across) at left of Saturn; Prometheus (102 kilometers, 63 miles across), Janus (181 kilometers, 113 miles across) and Enceladus (499 kilometers, 310 miles across) at right of Saturn.
The images were taken on May 7, 2004 from a distance of 28.2 million kilometers (17.6 million miles) from Saturn. The image scale is 169 kilometers (105 miles) per pixel. Moons in the image have been brightened for visibility.

The small moon Helene (33 kilometers, 21 miles across) leads Dione by 60 degrees in the moons' shared orbit. Helene is a "Trojan" moon of Dione, named for the Trojan group of asteroids that orbit 60 degrees ahead of and behind Jupiter as it circles the Sun.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 24, 2008 at a distance of approximately 68,000 kilometers (42,000 miles) from Helene and at a Sun-Helene-spacecraft, or phase, angle of 30 degrees. Image scale is 408 meters (1,338 feet) per pixel.

The original NASA image has been modified by cropping, doubling the linear pixel density and sharpening.Description from NASA :
In this view captured by NASA's Cassini spacecraft on its closest-ever flyby of Saturn's moon Mimas, large Herschel Crater dominates Mimas, making the moon look like the Death Star in the movie "Star Wars."
Herschel Crater is 130 kilometers, or 80 miles, wide and covers most of the right of this image. Scientists continue to study this impact basin and its surrounding terrain (see PIA12569 and PIA12571).
Cassini came within about 9,500 kilometers (5,900 miles) of Mimas on Feb. 13, 2010. This mosaic was created from six images taken that day in visible light with Cassini's narrow-angle camera on Feb. 13, 2010. The images were re-projected into an orthographic map projection. This view looks toward the area between the region that leads on Mimas' orbit around Saturn and the region of the moon facing away from Saturn. Mimas is 396 kilometers (246 miles) across. This view is centered on terrain at 11 degrees south latitude, 158 degrees west longitude. North is up. This view was obtained at a distance of approximately 50,000 kilometers (31,000 miles) from Mimas and at a sun-Mimas-spacecraft, or phase, angle of 17 degrees. Image scale is 240 meters (790 feet) per pixel.

It's difficult not to think of an egg when looking at Saturn's moon Methone, seen here during a Cassini flyby of the small moon. The relatively smooth surface adds to the effect created by the oblong shape.
Small moons like Methone are not generally spherical in shape like the larger moons. The closer to Saturn they are, the greater their tidal bulge. Their small sizes means that they lack sufficient gravity to pull themselves into round shape. Scientists think that the elongated shapes of these moons may be a clue to how they formed.
Lit terrain seen here is on the leading side of Methone (2 miles, 3 kilometers across). North on Methone is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 20, 2012.
The view was obtained at a distance of approximately 3,000 miles (4,000 kilometers) from Methone and at a Sun-Methone-spacecraft, or phase, angle of 63 degrees. Scale in the original image was 88 feet (27 meters) per pixel. The image has been magnified by a factor of 2.

- Cassini acquired infrared, green and ultraviolet images on Sept. 5, 2005, which were combined to create this false-color view. The image was taken with the Cassini spacecraft narrow-angle camera at a distance of approximately 52,000 kilometers (32,000 miles) from Pandora and at a Sun-Pandora-spacecraft, or phase, angle of 54 degrees. Resolution in the original image was about 300 meters (1,000 feet) per pixel. The image has been magnified by a factor of two to aid visibility.
This southerly view of Dione shows enormous canyons extending from mid-latitudes on the trailing hemisphere, at right, to the moon's south polar region.
This view looks toward the Saturn-facing side of Dione (1,126 kilometers, or 700 miles across) and is centered on 22 degrees south latitude, 359 degrees west longitude. North on Dione is up; the moon's south pole is seen at bottom.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 8, 2008. The view was obtained at a distance of approximately 211,000 kilometers (131,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 20 degrees. Image scale is 1 kilometer (0.6 mile) per pixel.Uploader's notes: The original NASA image has been modified by cropping, removing artifacts and increasing linear pixel dimensions by a factor of 1.295.

This raw, unprocessed image of Atlas was taken on April 12, 2017 and received on Earth April 13, 2017. The camera was pointing toward Atlas at approximately kilometers away, and the image was taken using the CL1 and IR1 filters. The image has not been validated or calibrated. A validated/calibrated image will be archived with the Planetary Data System in 2018.

PIA18317: Tethys the Target
http://photojournal.jpl.nasa.gov/catalog/PIA18317
Like most moons in the Solar System, Tethys is covered by impact craters. Some craters bear witness to incredibly violent events, such as the crater Odysseus (seen here at the right of the image).
While Tethys is 1,062 kilometers (660 miles) across, the crater Odysseus is 450 kilometers (280 miles) across, covering about 18 percent of the moon's surface area. A comparably sized crater on Earth would be as large as Africa!
This view looks toward the anti-Saturn hemisphere of Tethys. North on Tethys is up and rotated 42 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 11, 2015.
The view was acquired at a distance of approximately 190,000 kilometers (118,000 miles) from Tethys. Image scale is 1 kilometer (3,280 feet) per pixel.

This view looks toward the Saturn-facing side of Janus (179 kilometers, 111 miles across). North on Janus is up and rotated 10 degrees to the right.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 7, 2010. The view was acquired at a distance of approximately 75,000 kilometers (46,000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 39 degrees. Image scale is 448 meters (1,469 feet) per pixel.

Original caption: NASA's Cassini spacecraft captured this view as it neared icy Enceladus for its closest-ever dive past the moon's active south polar region. The view shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain in the middle and southern latitudes. The wavy boundary of the moon's active south polar region -- Cassini's destination for this flyby -- is visible at bottom, where it disappears into wintry darkness.
This view looks towards the Saturn-facing side of Enceladus. North on Enceladus is up and rotated 23 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 28, 2015.
The view was acquired at a distance of approximately 60,000 miles (96,000 kilometers) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 45 degrees. Image scale is 1,896 feet (578 meters) per pixel.Phoebe, as imaged by the Cassini probe.
