As Titan Turns

This map of the surface of Iapetus, generated from images taken by NASA's Cassini and Voyager spacecraft, illustrates the imaging coverage planned for Cassini's very close flyby of the two-toned mo...

The A and F rings are alive with moving structures in this Cassini spacecraft view. Graceful drapes of ring material created by Prometheus are seen sliding by at left, while clumpy ringlets slip th...

This graphic shows the orbits of all the known Potentially Hazardous Asteroids (PHAs), numbering over 1,400 as of early 2013. 

This view from NASA's Dawn spacecraft shows two medium-sized craters at high northern latitudes on Ceres.

Temperature changes mapped with Cassini's composite and infrared spectrometer throughout Saturn's main rings show the ring temperatures decreasing with the increase of the Sun-spacecraft-ring angle...

The sunlit face of Saturn's rings shows magnificent detail in this image taken in near infrared light. Most notable is the transition in brightness toward the outer edges of the image, due to diffe...

                  Rings and More Rings July 16, 2004   Full-Res: PIA05417   This dramatic view of Saturn's rings drap...

With pastel blues, pinks, greens and golds, Saturn displays a dazzling diversity of colors and hues. Here, Cassini looks upward at, and through, the sunlit side of the rings from about 19 degrees...

The biggest, most long-lasting Saturnian storm seen by either NASA's Cassini or Voyager spacecraft roils the atmosphere of the gas giant in this nearly true-color mosaic of Cassini images. See Enc...

The Cassini spacecraft captures here one of its closest views of Saturn's ring-embedded moon Daphnis. This image was taken July 5, 2010, at a distance of only about 75,000 kilometers (47,000 miles...

These images from NASA's Dawn spacecraft are located in asteroid Vesta's Numisia quadrangle, in Vesta's southern hemisphere. fine-scale structure of the slumping-related features on Drusilla's slop...

The Cassini spacecraft looks toward the battered surface of the moon Rhea. See Ancient Plains of Rhea and Bright Rays to learn more about this moon. This view looks toward leading hemisphere of Rh...

This artist's impression shows the 'light curve' produced by a star passing behind Titan, Saturn's biggest moon. When such occultation events take place, the light from the star is blocked out. B...

Although it is no longer uncharted land, the origin of the dark territory of Cassini Regio on Iapetus remains a mystery. Also puzzling is the equatorial ridge that bisects this terrain, and how it ...

The shadow of the moon Janus dwarfs the shadow of Daphnis on Saturn's A ring in this image taken as the planet approached its August 2009 equinox. Daphnis (8 kilometers, or 5 miles across) orbits ...

Dark material has coated the low-elevation terrain and the interiors of craters in the southern portions of the quadrant on Iapetus that faces away from Saturn. This is part of the boundary region ...

Seen here inside one half of its 62.7-foot tall fairing, the Parker Solar Probe was encapsulated on July 16, 2018, in preparation for the move from Astrotech Space Operations in Titusville, Florida...

Three months before its scheduled arrival at Saturn, the Cassini spacecraft has observed two storms in the act of merging. With diameters close to 1,000 kilometers (621 miles), both storms, which...

This image from NASA's Dawn spacecraft is located in Lucaria Tholus quadrangle, in Vesta's northern hemisphere. Around Publicia's rim are many alternating streaks of bright and dark material tumbli...

This image of Juling and Kupalo Craters was obtained by NASA's Dawn spacecraft on May 25, 2018 from an altitude of about 855 miles (1380 kilometers).

The bright whorls and small-scale specks of convective clouds drift through a region just north of Saturn's bright equatorial band. Observers have seen major storms develop in this region in the pa...

This Cassini spacecraft image provides a view of the southern portion of Tethys' trailing hemisphere. Prominent features include the huge canyon, Ithaca Chasma, approximately centered in this view...

ORIGINAL CAPTION: The Cassini spacecraft awaits placement of its payload fairing at Launch Pad 40 at Cape Canaveral Air Station (CCAS) to protect Cassini during launch. 

Two dark gores in Saturn's F ring demonstrate the gravitational influence of the shepherd moon Prometheus. The older gore at the top of this view is at a steeper angle than the newer addition jus...

The sharp change in brightness that runs diagonally across the center of this image represents the boundary between Saturn's C and B rings. This location sits at about 92,000 kilometers (57,200 mi...
