Atmospheric Motion

This illustrated timeline features milestones in the journey of NASA's Cassini spacecraft.

This colorized mosaic from NASA's Cassini mission shows the most complete view yet of Titan's northern land of lakes and seas. Saturn's moon Titan is the only world in our solar system other than E...

+ Unlabeled version Scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years. The pattern ripples back and forth like a wave withi...

Artist's concept of Cassini orbiter crossing Saturn's ring plane.

In the spirit of the Halloween season, the Cassini team has put together The Eerie Sounds of Saturn.   + More information on Saturn's Radio Emissions   + More featured "Sounds of Saturn"

Artist's concept of Cassini orbiter diving between Saturn's inntermost rings and cloud tops.

This still is from a short computer-animated film that highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017.

Images from the magnetospheric imaging instrument and the ion and neutral camera onboard the Cassini spacecraft reveal aspects of the interactions between Saturn's dynamic population of hot energet...

This figure illustrates the unexpected and bizarre pattern of daytime temperatures found on Saturn's small inner moon Mimas (396 kilometers, or 246 miles, in diameter). 

This graphic represents a possible model for mechanisms that could generate the water vapor and tiny ice particles detected by Cassini over the southern polar terrain on Enceladus. This model shows...

This artist's concept shows "tides" on Titan raised by Saturn's gravity, as detected by NASA's Cassini spacecraft. Saturn's gravitational pull on Titan, its largest moon, varies as Titan orbits ...

Artist's rendition of our solar system. Not to scale. 

This image, which is composed of data obtained by NASA's Cassini spacecraft, shows the topography of a mountain known as Janiculum Dorsa on the Saturnian moon Dione.

The release of the Huygens probe on Dec. 25, 2004 set the festive tone of holiday seasons for the duration of the misison.

Artist's concept of our solar system showing a sense of scale and distance.

The icy crust is thinner in the polar regions, below which sits an ocean.

These illustrations indicate possible ways in which the water vapor and ice particles in the plume of Enceladus may be formed. The Cassini spacecraft recently found a small fraction of salt-rich ic...

Some key numbers for Cassini's Grand Finale and final plunge into Saturn. 

Dawn's futuristic, hyper-efficient ion propulsion system allows Dawn to go into orbit around two different solar system bodies, a first for any spacecraft.

This diagram created by Cassini's mission planning team shows how navigators use Titan flybys to shape Cassini's orbits.

A simplified model of Jupiter's massive magnetic field, known as a  magnetosphere.

This computer-generated animation shows all of Cassini's orbits - affectionaly called the "ball of yarn" by mission planners.

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...

Take a virtual trip to alien worlds, and maybe even plaster your living room with new, futuristic space tourism posters.

This plot shows results from Cassini's ion neutral mass spectrometer and cosmic dust analyzer, obtained during the spacecraft's close approach to Enceladus on July 14, 2005.
