Probe Landing on Titan

Artist's concept of the Dawn spacecraft gathering spectral data from Vesta.

Cassini kicked off the year with a successful flyby of Titan on Jan. 15. Cassini will add to the wealth of data with new vistas during 13 Titan flybys planned for this year. Raw images from the mos...

Titan's fast-rotating atmosphere creates circumpolar bands in the north. The Cassini spacecraft acquired this view of the smoggy moon following a flyby of Titan (5,150 kilometers, or 3,200 miles a...

NASA's Cassini spacecraft successfully completed its Oct. 1 flyby of Saturn's moon Enceladus, capturing these raw, unprocessed images of the moon and its dramatic plumes of water vapor and ice. Th...

Occator Crater, home of Ceres' intriguing brightest areas, is prominently featured in this image from NASA's Dawn spacecraft.

This synthetic aperture radar image was obtained by the Cassini spacecraft on its pass by Titan's south pole on Dec. 20, 2007. This image is centered near 76.5 south, 32.5 west and covers an area ...

The Herschel crater dominates this view of Saturn's moon Mimas. The 130-kilometer, or 80-mile, wide crater is located in the middle latitudes of Mimas (396 kilometers, or 246 miles across). The m...

+ Read Feature NASA's Cassini spacecraft took this raw, unprocessed image of Saturn's moon Rhea on March 10, 2012. The camera was pointing toward Rhea at approximately 26,257 miles (42,258 kilomet...

The low Sun elevation in this scene emphasizes the topography of Van Eyck crater.

During a recent pass of Saturn's moon Titan, one of more than 40 during Cassini's planned four-year mission, the spacecraft acquired this infrared view of the bright Xanadu region and the moon's so...

The terrain model of Vesta's southern hemisphere shows a big circular structure, its rim rising above the interior of the structure. This false-color map of the giant asteroid Vesta is from the fra...

In a rare moment, the Cassini spacecraft captured this enduring portrait of a near-alignment of four of Saturn's restless moons. Timing is critical when trying to capture a view of multiple bodies,...

This view is among the closest Cassini images of Tethys' icy surface taken during the Sept. 24, 2005 flyby. This false-color image, created with infrared, green and ultraviolet frames, reveals a w...

This image, taken by NASA's Dawn spacecraft, shows dwarf planet Ceres from an altitude of 2,700 miles (4,400 kilometers). The image, with a resolution of 1,400 feet (410 meters) per pixel, was take...

A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA's Cassini spacecraft.

This video describes Cassini measurements of high speed streams of tiny dust particles emanating from the vicinity of Saturn. It presents actual dust measurements and displays Cassini measurements ...

After more than 13 years at Saturn, and with its fate sealed, NASA's Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last,...

This scene viewed by NASA's Dawn spacecraft on Oct. 20, 2016, from Ceres features terrain near the rim of the large crater named Kerwan, at lower left. A much smaller, fresher crater called Cacagua...
