During its final months, the Cassini spacecraft will climb repeatedly high above the planet’s north pole and then dive between the planet and the innermost edge of its dazzling rings.​

In the decade since NASA’s Cassini delivered ESA’s Huygens probe to the hidden surface of Titan, our knowledge of Saturn’s largest moon has grown by leaps and bounds.

This is an artists concept of Cassini during the Saturn Orbit Insertion (SOI) maneuver, just after the main engine has begun firing. The spacecraft is moving out of the plane of the page and to the...

To create the first global, topographic map of Saturn's moon Titan, scientists analyzed data from NASA's Cassini spacecraft and a mathematical process called splining. This method effectively uses ...

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.

This whimsical travel poster imagines a future regatta where explorers recreate Voyager 1 and 2's historic Grand Tour of the outer solar system.

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

Eight of Cassini's science instruments are planned to be turned on during the final plunge.

Saturn's clouds and hazes at three different levels in the atmosphere are depicted in the image on the right, as observed by the visual infrared mapping spectrometer on the Cassini spacecraft. In ...

Here’s how the solar wind interacts with a few select planets and other celestial bodies.

+ Unannotated Version The northern and southern hemispheres of Enceladus are seen in these polar stereographic maps, mosaicked from the best-available Cassini clear-filter images. Each map is...

This graphic summarizes Cassini's 13 years orbiting Saturn, with moon flybys grouped into columns for each phase of the mission. 

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 ...
