Moving Cassini for Testing

Off the shoulder of giant Saturn, a bright pinpoint marks the location of the ring moon Atlas (image center). Shadows cast by the C ring adorn the planet at upper right. The thin boundary of Satur...

A fresh look at Saturn's moon Enceladus reveals tempting new details about the brightest real estate in the solar system. This false-color image shows that some of the linear features on Enceladus ...

This color picture is made from images taken by the imaging system on NASA Galileo spacecraft about 14 minutes before its closest approach to asteroid 243 Ida on August 28, 1993. 

Pandora is seen here, in isolation beside Saturn's kinked and constantly changing F ring.

From Saturn orbit, the Cassini spacecraft provides a perspective on the ringed planet that is never seen from Earth. In our skies, Saturn's disk is always nearly fully illuminated by the sun. From...

As Cassini hurtled toward its fatal encounter with Saturn, the spacecraft turned to catch this final look at Saturn's moon Pandora next to the thin line of the F ring.

This image, taken by NASA's Dawn spacecraft, features a crater at lower right with a sharp rim and bright material on its walls. The image, with a resolution of 1,400 feet (410 meters) per pixel, w...

The F ring shepherd Pandora is captured here along with other well-known examples of how Saturn’s moons shape the rings. 

Herschel Crater features prominently on the moon Mimas in this Cassini spacecraft image, which gives the impression of an eye staring out into space. Herschel Crater is about 130 kilometers, or 81...

This image from NASA's Dawn spacecraft shows the brightest area seen on asteroid Vesta so far. It shows a crater located inside the rim of the Rheasilvia basin at the south pole of Vesta.

The moon Rhea moves behind Saturn's largest moon, Titan, in this "mutual event" imaged by the Cassini spacecraft. Mutual event sequences, in which one moon passes close to or in front of another, ...

A view of the far side of the Moon as it passed in front of Earth from a vantage point more than a million miles away.

This image, taken by NASA's Dawn spacecraft, shows a portion of the northern hemisphere of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image, with a resolution of 450 f...

A mosaic of two images of Saturn's moon Phoebe taken shortly after Cassini's flyby on June 11, 2004, gives a close-up view of a region near its South Pole. The view, taken about 13,000 kilometers (...

The huge Odysseus Crater is clearly illuminated by the sun on the western limb of Tethys, but Saturn shining from the right makes the smaller craters on the eastern part of the moon also visible. ...

The Cassini spacecraft looks toward the dark side of Saturn's largest moon and captures the halo-like ring produced by sunlight scattering through the periphery of Titan's atmosphere. A detached, ...

Breathtaking Vista November 23, 2004 Full-Res: PIA06526 This dazzling view looks beyond gigantic storms near Saturn's south pole t...

This mosaic of images from NASA's MESSENGER spacecraft shows the impact crater Hokusai on Mercury.

Prometheus and Epimetheus, brothers in Greek mythology, share the stage in this Cassini spacecraft image of the two moons near the outer A ring and faint F ring.

In this image, dwarf planet Ceres is seen on Feb. 4, 2015, from a distance of about 90,000 miles (145,000 kilometers). NASA's Dawn spacecraft is due to arrive at Ceres on March 6, 2015.

These views of Ceres, taken by NASA's Dawn spacecraft on December 10, show an area in the southern part of the southern hemisphere of the dwarf planet.

The Cassini spacecraft looks down on the north pole of Mimas and sees the moon's cratered trailing hemisphere. The moon's north pole lies on the terminator about a quarter of the way inward from t...

The Cassini spacecraft views the rugged surface of Mimas -- half lit by the Sun, and half lit by reflected light from Saturn. On the sunlit western limb lies the great Herschel impact crater. The ...
