Spacecraft Trajectory

This composite infrared image, derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission to Jupiter during a Feb. 2, 2017, pass over the planet...

Saturn's rings appear curved in this Cassini spacecraft view, which also shows the moon Janus in the distance. Janus (179 kilometers, or 111 miles across) is at the bottom of the image and is fart...

The Cassini spacecraft looks toward Fensal and Aztlan, two dark areas near the equator of Titan. Like other albedo features on Titan, these areas are named after enchanted places or paradises from...

This close-up image of the Vinalia Faculae in Occator Crater on Ceres, obtained by NASA's Dawn spacecraft on June 14, 2018, reveals the intricate pattern between bright and dark material across thi...

Oozing Across Titan November 8, 2004 Full-Res: PIA06993 This synthetic aperture radar image of the surface of Saturn's moon Titan was acq...

Heavily-shadowed craters in the northernmost latitudes of Ceres are seen in this view from NASA's Dawn spacecraft, taken on Jan. 25, 2016.

The right-hand limb of Saturn's moon Mimas appears flattened as Herschel Crater is viewed edge-on in this Cassini spacecraft image. The planet's rings are in the background. Herschel Crater is 130...

This false-color picture of Saturn's moon Rhea from Cassini enhances slight differences in natural color across the moon's face. The extreme north and south latitudes have a notable difference in h...

Russia's Zond 5 -- carrying an extensive biological payload including two steppe tortoises -- was the first successful circumlunar mission.

Scientists from the Descent Imager/Spectral Radiometer (DISR) team analyze initial data sent back by the Huygens probe in the Principle Investigator Support Area (PISA), at ESOC, Darmstadt, Germany...

+ Viewing options The small moon Janus overtakes the larger moon Rhea in a dance played out before Saturn and its rings. Observations of mutual moon-crossing events like this one, in which on...

The Cassini spacecraft spies two of the small, irregular moons that patrol the outer edges of Saturn's main rings. Prometheus (102 kilometers, or 63 miles across) hugs the interior of the F ring r...

This is the separate version of the infrared image that accompanies the feature Cassini Sees Saturn Storm's Explosive Power The visible-light image can be seen separately here: Catching Its Tail...

Saturn's moon Helene, seen here with Saturn's nearly edge-on rings, orbits 60 degrees ahead of Dione and is called a "Trojan" moon. The tiny moon Polydeuces (about 5 kilometers or 3 miles across, r...

These raw, unprocessed images of Saturn's moon Dione were taken on Dec. 12, 2011, by NASA's Cassini spacecraft. Although Cassini obtained more detailed images on previous flybys of Dione, this was ...

Artist's rendition, part of the Dawn Mission Art series.

This color image of the Sun, Earth and Venus was taken by the Voyager 1 spacecraft Feb. 14, 1990, when it was approximately from a distance of about 4 billion miles. 

Jets of icy particles burst from Saturn's moon Enceladus in this brief movie sequence of four images taken on Nov. 27, 2005. The sensational discovery of active eruptions on a third outer solar sys...

This artist's concept shows a simulated view from the surface of Jupiter's moon Europa. Europa's potentially rough, icy surface, tinged with reddish areas that scientists hope to learn more about, ...

Two icy moons meet on the sky in a "mutual event" recorded by the Cassini spacecraft. The great brightness of Enceladus (505 kilometers, or 314 miles across) is rather obvious in comparison to Dio...

This view of Saturn's moon Rhea includes two large and ancient impact basins and a more recent, bright ray crater. The large basin above center is named Tirawa. This feature (and the similar-size...

Below a darkened Enceladus, a plume of water ice is backlit in this view of one of Saturn's most dramatic moons. See Bursting at the Seams and Jet Blue to learn more about the jets of water ice em...

Booters Separating

This image from NASA's Dawn spacecraft of asteroid Vesta shows Laelia crater and Sextilia crater, located in Vesta's Sextilia quadrangle, in Vesta's southern hemisphere.

Light from the star Beta Crucis (Mimosa) breaks through the plane of the A ring in the center of this image of a stellar occultation. Several of Cassini's remote-sensing instruments use occultatio...
