The flyby changed Cassini’s trajectory, moving the low point of the spacecraft’s elliptical orbit from just outside to just inside the planet’s vast ring system.

On April 22, Cassini carried out a Titan flyby that kicked off the "Grand Finale," putting the spacecraft on a trajectory that repeatedly carried it between the innermost rings and Saturn's cloud ...

The spacecraft Cassini will become a streak of ash when it tumbles into Saturn on Friday. Less than a million miles away, the probe Huygens, which Cassini launched onto Saturn's moon Titan, will ...

The Cassini Spacecraft Has Entered Its Final Collision Course with Saturn 2 minute read This picture shows a 1:25 scale model of the Cassini spacecraft.

Scientists have a plan to extend the life, on relatively little fuel, of NASA’s Cassini spacecraft, now in its sixth year of studying Saturn.

NASA’s Cassini spacecraft has successfully executed its daring dive, hurtling through the 1,500-mile-wide gap between Saturn and its rings.

Cassini was low on fuel even before changing trajectory from its orbit well outside the rings into the current ring-grazing orbit.

Cassini is making its first-ever pass between Saturn and its rings, a potentially dangerous start to the orbiter's final mission.

In this image, the final trajectory of Cassini is shown rising from beyond Saturn before descending into its atmosphere on the Earth-facing side of the planet about 30 minutes later.

Aside from the smog-shrouded moon’s inherent interest to scientists, Titan is the only moon with enough mass to significantly alter Cassini’s trajectory, which makes the complex 4-year tour ...

In April, Titan’s gravity nudged Cassini into a trajectory that took the orbiter between Saturn and its rings, from which there was no return but only, as NASA puts it, a “grand finale.” ...

NASA’s Cassini probe has begun an unprecedented space dive that will see it plunge through the icy rings of Saturn, in the final phase of its 20-year mission.
