This map of Titan's surface illustrates the regions that will be imaged by Cassini during the spacecraft's close flyby of Titan on Aug. 22, 2005. At closest approach, the spacecraft is expected to ...
Planned Image Coverage -- Aug. 22, 2005, Titan Flyby
This image of Serena AV-L-18, from the atlas of the giant asteroid Vesta, was created from images taken as NASA's Dawn mission flew around the object, also known as a protoplanet.
Dione and Saturn December 16, 2004 Full-Res: PIA06155 Cassini captured Dione against the globe of Saturn as it approached the icy ...
Dione and Saturn
This set of images from the radar instrument on NASA's Cassini spacecraft shows a relatively "fresh" crater called Sinlap (left) and an extremely degraded crater called Soi (right). Sinlap has a de...
Titan Craters, the Old and the New
This stereographic projection of Descent Imager/Spectral Radiometer images from the European Space Agency's Huygens probe combines 60 images in 31 triplets, projected from a height of 3,000 meters ...
Huygens Titan Mosaic #1
The shadow of the moon Tethys is cast onto Saturn's A ring, almost blanketing the Enke Gap. The novel illumination geometry created as Saturn approaches its August 2009 equinox allows moons orbiti...
Engulfing a Gap
Cassini captures a crater duo on Saturn's moon Dione that is superimposed on older, linear features. The upper of the pair, named Italus, is overprinted on a grouping of ancient troughs called Pete...
Helorus in Half-light
The Cassini spacecraft looks close at Saturn to frame a view encompassing the entire C ring. In the dark region closer to the planet lies the much dimmer D ring. The bright B ring wraps around the ...
Framing the C Ring
This image from NASA's Dawn spacecraft of asteroid Vesta shows Aquilia crater located in Pinaria quadrangle, in Vesta's southern hemisphere. The especially degraded bottom rim was probably formed b...
This artist's concept summarizes our understanding of how the inside of Ceres could be structured, based on the data returned by the NASA's Dawn mission. The most internal layer, the mantle is domi...
Ceres' Internal Structure (Artist's Concept)
This image of Saturn's largest moon, Titan, obtained by Cassini's radar instrument during a near-polar flyby on Feb. 22, 2007, features dunes and lakes, one of which is larger than any lake on Eart...
Titan (T25) Viewed by Cassini's Radar - Feb. 22, 2007
Both luminous and translucent, the C ring sweeps out of the darkness of Saturn's shadow and obscures the planet at lower left. The ring is characterized by broad, isolated bright areas, or "plateau...
Scintillating C Ring
A fine spray of small, icy particles emanating from the warm, geologically unique province surrounding the south pole of Saturn's moon Enceladus was observed in a Cassini narrow-angle camera image ...
Spray Above Enceladus
These images from NASA's Dawn spacecraft are located in asteroid Vesta's Sextilia quadrangle, in Vesta's southern hemisphere.

Hyperion -- Raw Image 2
The low sun elevation in this image of NASA's Dawn spacecraft of asteroid Vesta enhances small topographic details near the rim of the large crater, part of which is visible in the bottom left of t...
Blocks of Ejected Material and Small Craters Near a Crater Rim
This image from NASA's Dawn spacecraft shows many craters of different sizes and states of preservation on asteroid Vesta's surface. In the top of the image there are four large, very degraded crat...
Cratered Surface of Vesta
This view from NASA's Dawn spacecraft captured on June 1, 2016, shows an older crater on Ceres that is smoothly blanketed by ejecta from the nearby, relatively young crater named Kupalo.
Dawn LAMO Image 170
The shadow of Saturn's largest moon darkens a huge portion of the gas giant planet. Titan (5,150 kilometers, or 3,200 miles across) is not pictured here, but its shadow is elongated in the bottom ...
Enormous Elongated Shadow
Although travelling at great speed, the Cassini spacecraft managed to capture this close view of Saturn's small moon Helene during a flyby on March 3, 2010.
Pandora is seen in this dramatic view, orbiting just beyond the outer edge of Saturn's F ring. Several bright areas are visible within the F ring. In the main rings, the Keeler gap and the Encke ga...
Pandora at the Edge
Nature is an artist, and this time she seems to have let her paints swirl together a bit.
This image shows the northern and southern hemispheres of Titan, showing the disparity between the abundance of lakes in the north and their paucity in the South. The hypothesis presented favors lo...
Lake Asymmetry on Titan
These images from NASA's Dawn spacecraft are located in asteroid Vesta's Gegania quadrangle, just south of Vesta's equator. Rubria is the crater with dark and bright material above Divalia Fossa an...
