Below a darkened Enceladus, a plume of water ice is backlit in this view of one of Saturn's most dramatic moons. The Cassini spacecraft looks at a brightly illuminated Enceladus and examines the surface of the leading hemisphere. The brightly reflective moon Enceladus appears before Saturn's rings while the larger moon Titan looms in the distance. The brightly illuminated Enceladus, showing the surface of the leading hemisphere of this Saturnian moon.

The third-largest moon Dione can be seen through the haze of the largest moon, Titan, in this view of the two posing before the planet and its rings. Mimas peeps out from behind the larger moon Dione.  Mimas (246 miles, or 396 kilometers across) is near the bottom centre of the image. Saturn's rings are also visible in the top right. Saturn and Dione appear askew in this view, with the north poles rotated to the right, as if they were threaded along on the thin diagonal line of the planet's rings. Saturn's moons Daphnis and Pan demonstrate their effects on the planet's rings.

This unprocessed image of Saturn's moon Helene was obtained on June 18, 2011. Vertical structures, among the tallest seen in Saturn's main rings, rise abruptly from the edge of Saturn's B ring to cast long shadows on the ring in this image, taken two weeks before the planet's August 2009 equinox. Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan. This raw, unprocessed image of Rhea was taken on March 10, 2012. The camera was pointing toward Rhea at approximately 26,019 miles (41,873 kilometres) away.

Cassini looks over the heavily cratered surface of Rhea during the spacecraft's flyby of the moon on March 10, 2012. The month of January is named for the Roman god Janus, who guarded the gate of heaven. This image of the heavily cratered, irregularly shaped, 181Km diameter moon shows vague hints of it's surface morphology. A superb closer view of Janus taken in October 2006 Irregularly shaped Epithemius, seen against the backdrop of the planet's rings, which are nearly edge-on in this view. Some of the moon's larger geological features can be seen here. Epimetheus is 116 kilometers (72 miles) across

Epithemius again, from 34 degrees above Saturn's equatorial plane. The two largest craters visible here are the only officially named features on this moon. At the left (at about the 9 o'clock position) is Pollux; and at lower left (containing a string of several smaller craters) is Hilairea. Saturn's small, potato-shaped moon Prometheus appears embedded within the planet's rings near the centre of this view while the larger moon Mimas orbits beyond the rings. Mimas peeks out from behind the night side of the larger moon Dione in this image captured during the spacecraft's Dec. 12, 2011, flyby of Dione. Mimas joins the planet's rings which appear truncated by the planet's shadow in this image. Saturn is off to the left, out of view here. The inner rings are just visible, but the planet's shadow covers part of the rings across the middle of the image. Mimas (246 miles, or 396 kilometers across) is closer to Cassini than the rings are here.

Janus (179 km across) is on the far left. Pandora (81 km across) orbits between the A ring and the thin F ring near the middle of the image. Brightly reflective Enceladus (504 km across) appears above the centre of the image. Saturn's second largest moon, Rhea (1,528 km across), is bisected by the right edge of the image. The smaller moon Mimas (396 km across) can be seen beyond Rhea also on the right side of the image.
Shadows darken parts of some of Janus' large craters as Cassini takes a close look on March 27, 2012. Janus is 179Km across) and periodically swaps orbits with Epimetheus. Saturn's far-off moon Hyperion. This view was obtained at a distance of approximately 521,000 km from Hyperion and at a Sun - Hyperion - spacecraft, or phase, angle of 90 degrees. Hyperion (270 km across) has an irregular shape, and it tumbles through its orbit: that is, it does not spin at a constant rate or in a constant orientation. A huge storm marches across the northern hemisphere of the planet.

Cassini obtained this raw image of Titan and Tethys on Oct. 18, 2010. Titan, Saturn's largest moon, is the larger, hazy moon in the background. Tethys is the bright icy moon in the foreground. The rings of Saturn faintly etch the top of this image. Titan (5,150 km across) is in the upper right. Saturn's rings appear across the top of the image, and they cast a series of shadows onto the planet across the middle of the image. Prometheus (86 km across) appears as a tiny white speck above the rings in the far upper right of the image. The shadow cast by Prometheus can be seen as a small black speck on the planet on the far left of the image, between the shadows cast by the main rings and the thin F ring. The shadow of the moon Pandora also can be seen on the planet south of the shadows of all the rings, below the center of the image towards the right side of the planet.
The colourful globe of Saturn's largest moon, Titan, passes in front of the planet and its rings in this true colour image. The north polar hood can be seen on Titan (5150 km across) and appears as a detached layer at the top of the moon here.
Larger Titan is on the left. Tethys (1,062 km across) is near the centre of the image. This view looks toward the Saturn-facing sides of Tethys and Titan. The angle also shows the northern, sunlit side of the rings from less than one degree above the ring plane.

Tethys orbits in front of the wide shadows cast by the rings onto the planet. Tethys (1,062 km across) appears just below the rings near the centre of the image. This view looks toward the northern, sunlit side of the rings from less than one degree above the ring plane.

Tethys shows off its tortured surface in this image. On the top left of the image there is huge Odysseus Crater. On the bottom right there is Ithaca Chasma, a series of scarps that runs north-south across the moon for more than 1,000 km. North on Tethys is up and rotated 25 degrees to the right. This raw image of Titan was taken on Oct. 18, 2010. Bright clouds streak the moon's midsection, likely an indication of changing seasons and the arrival of spring in the northern hemisphere. Cassini's imaging camera was about 2.5 million km away from Titan. The rings of Saturn faintly etch the top of this image. Tethys (1,062 km across) appears as a small white dot above the rings on the far left of the image. Enceladus (504 km across) appears as a smaller bright speck beside the planet as seen from this vantage point. The rings cast wide shadows on the planet's southern latitudes.
