Final Assembly at the Cape

This life-like movie sequence captures Saturn's rings during a ring plane crossing--which Cassini makes twice per orbit--from the spacecraft's point of view.

These false-color mosaics from NASA's Cassini spacecraft chronicle the changing appearance of the huge storm that developed from a small spot in Saturn's northern hemisphere.

The Cassini spacecraft arrived at Saturn in June 2004 and is now halfway through its mission. A new photo essay showcases some stunning images returned by the mission.

As Huygens descends Titan's atmosphere, Cassini will record the data from 72,000 kilometers (about 44,700 miles).

Hello, my name is Janelle. I think the best topic is number 2, Titan.

Ion propulsion isn’t something found only in science fiction. JPL engineer Mike Meacham looks at how ion engines are being used to drive NASA's Dawn spacecraft through the solar system.

These two false-color views from NASA's Cassini spacecraft show detailed patterns that change during one Saturn day within the huge storm in the planet's northern hemisphere.

This time-lapse video captures a portion of the path that tiny Phobos takes around Mars. 

Team members reflect on Spirit's six-years of roving Mars.

This animation based on data obtained by NASA’s Cassini spacecraft shows how the “explosions” of hot plasma on the night side (orange and white) periodically inflate Saturn’s magnetic field (white ...

This animation illustrates Jupiter's magnetic field.

NASA's New Horizons spacecraft launched toward Pluto in 2006, but the mission can trace its start back to 1930, when Clyde Tombaugh discovered the small planet and opened the door to a new, mysteri...

The moon Prometheus slowly collides with the diffuse inner edge of Saturn's F ring in this movie sequence of Cassini images.

This animation, derived from data obtained by NASA’s Cassini spacecraft, shows how plasma swirling around Saturn is correlated to bursts of radio waves emanating from the planet.

JPL's Dawn mission is en route to rendezvous with the main-belt asteroids Vesta and Ceres, and is using ion propulsion to get there.

Have you ever seen a meteorite streaking across the sky? If so, you may very well have seen part of the asteroid, Vesta!

NASA's Cassini has found salt in Saturn's E ring, hinting that the moon Enceladus could have an underground liquid reservoir, perhaps even an ocean.

Recent findings have led scientists to believe Saturn's moon Titan may have a volcano.

This is a compilation of the Saturn hexagon movies released on Dec. 5, 2013.

This video shows the scientists' best guess to date of what the surface of the protoplanet Vesta might look like.

While NASA's Cassini spacecraft was pointed to study Saturn's F ring, it happened to catch a globular star cluster passing through the camera's field of view.
