The slim crescent of Ceres smiles back as the dwarf planet awaits the arrival of an emissary from Earth. This image was taken by NASA's Dawn spacecraft on March 1, 2015, just a few days before it a...

Dark Side of Dione July 19, 2004 Full-Res: PIA05418 The icy, cratered surface of Saturn's moon Dione shows more than just its sunl...

This global color mosaic of Saturn's moon Dione was produced from images taken by NASA's Cassini spacecraft during its first 10 years exploring the Saturn system.

+ 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...

This map of Saturn's moon Titan shows the location mapped with the Cassini radar mapper using its synthetic aperture radar imaging mode during the Oct. 28, 2005, flyby. The radar swath is superim...

This image combines two separate views of the giant asteroid Vesta obtained by NASA's Dawn spacecraft. The data reveal a world of many varied, well-separated layers and ingredients.

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.

This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on September 9, 2015, and has a resolution...

The broad morphology of asteroid Vesta's mountain/central complex is clear in this image from NASA's Dawn spacecraft; it is a roughly circular topographic mound, which is approximately 200km in dia...

Rhea's devastated surface creates a jagged terminator as mountains and crater rims break-up the line between day and night. Terrain on Rhea's night side is dimly lit by reflected light from Saturn....

Two-Tone Titan June 16, 2004 Full-Res: PIA05407 Cassini¿s finely-tuned vision reveals hazes high in the skies over Titan in this ...

Jezero Crater is the landing site for NASA's Mars 2020 rover.

+ Annotated version The northern and southern hemispheres of Rhea are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager images. Six Voyager images fill...

A Girl Scout waits to look through a telescope at the first-ever White House Campout with fifty fourth-grade girls in 2015.

This artist's rendition shows the Huygens probe as it reaches the surface of Titan. The Cassini spacecraft (top left corner of the image) flies over with its High Gain Antenna pointed at the probe....

Cassini peers through the icy particles that comprise Saturn's rings as Prometheus sits perched on the planet's limb (edge). 

NASA's Cassini spacecraft looks toward the night side of Saturn's largest moon and sees sunlight scattering through the periphery of Titan's atmosphere and forming a ring of color. Titan's north p...

The most visually striking feature on Saturn’s icy moon Tethys is Odysseus crater.

This mosaic of oblique images highlights the spectacular interior of Abedin crater.

NASA’s Terra satellite caught a glimpse of plumes rising from two volcanoes in January 2018. 

The Cassini spacecraft looks down at craters near the north pole of Enceladus. Cratered surfaces on solar system moons indicate older terrains, while smooth surfaces are generally younger, and t...

Exposed interior of NASA's Dawn spacecraft showing ion propulsion system's xenon feed system.

Two tiny moons of Saturn, almost lost amid the planet's enormous rings, are seen orbiting in this image. Pan, visible within the Encke Gap near lower-right, is in the process of overtaking the slow...

A line of dark vortices charge through Saturn's "Storm Alley" -- a region that has seen intensive storm activity since the Cassini spacecraft began its observations of the planet in early 2004. Th...

Cassini's celestial sleuthing has paid off with a series of images which confirmed earlier suspicions that a small moon was orbiting within the narrow Keeler gap within Saturn's rings. This view w...
