Artist's concept

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 ...

Spacecraft specialists huddle to discuss the critical lift of NASA's Phoenix Mars Lander into a thermal vacuum chamber.

Small water ice particles fly from fissures in the south polar region of Saturn's moon Enceladus in this image taken during the Aug. 13, 2010, flyby of the moon by NASA's Cassini spacecraft. This ...

A small new found object, temporarily designated S/2004 S 3, has been seen orbiting Saturn's outer F ring. 

In this view captured by NASA's Cassini spacecraft on its closest-ever flyby of Saturn's moon Mimas, large Herschel Crater dominates Mimas, making the moon look like the Death Star in the movie "St...

This is a collection of the most detailed images of deep-level clouds obtained by the visual and infrared mapping spectrometer onboard the Cassini spacecraft. Images were obtained at 5.1 micron wa...

Portrait of the prime crew of the Apollo 12 lunar landing mission.

An artist's concept of NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft firing its maneuvering thrusters in order to maintain a safe altitude as it orbits the moon.

This image shows the scientists' best guess to date of what the surface of the protoplanet Vesta might look like from the south pole and incorporates the best data on dimples and bulges Vesta from ...

This raw image (N00161009.jpg) was taken on August 14, 2010 and received on Earth August 14, 2010. The camera was pointing toward TETHYS at approximately 38,327 kilometers away, and the image was t...

NASA's New Horizons spacecraft observations of Kuiper Belt object Quaoar ("Kwa-war"), which - at 690 miles or 1,100 kilometers in diameter - is roughly half the size of Pluto.

In this image of the F ring, taken shortly after its ring particles encountered the shepherd moon Prometheus, the disruption to the ring caused by the moon is evident. The bright core of the ring ...

This view from NASA's Dawn spacecraft captures a portion of Ceres near the equator, including a crater surrounded by bright material. The image is centered at approximately 2.5 degrees south latitu...

+ Also see Titan's Lingering Clouds -- Annotated Lots of clouds are visible in this infrared image of Saturn's moon Titan. These clouds form and move much like those on Earth, but in a much slower...

A pair of moon shadows and a series of spokes adorn this ring image taken about a month after Saturn's August 2009 equinox. The shadow of the moon Janus stretches across the middle of the image. T...

+ See Movie   A brilliant spot of sunlight, the opposition effect, travels outward across the rings as the Cassini spacecraft orbits Saturn. This surge in ring brightness is created around the p...

The inset perspective view from NASA's Dawn space of Ceres' bright spot Occator Crator is overlaid with data concerning the composition. Red signifies a high abundance of carbonates, while gray ind...

The image shows change in sea ice and solar absorption in the summer months in the Arctic between 2000 and 2014. Blue shows where sea ice has decreased, and red shows where solar radiation absorpti...

A portion of the rim of giant Yalode Crater is seen in this image of Ceres. Yalode is approximately 162 miles (260 kilometers) in diameter. NASA's Dawn spacecraft took this image on June 15, 2016.

NASA's Dawn spacecraft took this image on June 6, 2015, which includes an intriguing pyramid-shaped mountain protruding from a relatively smooth area in the upper right.

Multiple jets of icy particles are blasted into space by the active venting on Saturn¿s moon Enceladus. This image was acquired in a viewing geometry that makes the tiny particles in the Enceladus...

Saturn's A ring appears bright compared to the thin F ring, which is shepherded by the moon Prometheus, in this view from the Cassini spacecraft. Prometheus can be seen near the F ring on the midd...

This image of Ceres, taken by NASA's Dawn spacecraft, shows terrain in the southern hemisphere within the large crater called Yalode. The prominent crater at top-right is called Lono. The crater di...

Cassini's "eyes" -- its powerful imaging cameras -- bear witness to the majestic and spectacular sights of the Saturn system, as this views attests. Here, the probe gazes upon Titan (5,150 kilomete...

The Cassini spacecraft captures a glimpse of the moon Atlas shortly after emerging from Saturn's shadow.
