Release of Probe

Giovanni Cassini, the astronomer, discovers a moon near Saturn. Half is dark as coal. The other half, bright as snow. Three centuries later, Cassini, the spacecraft, flies by for a close look.

This animation re-creates the final descent of ESA's Huygens probe as it landed on Titan on Jan. 14, 2005, after it was dropped off by NASA's Cassini spacecraft.

Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion.

  Take a virtual ride with Voyager 1 and 2 past Jupiter, Saturn, Uranus and Neptune.

NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989.

A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.

Io Color Eclipse

This short animation created by Cassini's mission planning team shows how a Titan flyby will be used to move the spacecraft's course from orbiting Cassini's outer ring (F ring) to an orbit that tak...

This is the first footage of one orbiting robotic spacecraft taken by another orbiting robotic spacecraft at Earth's moon. 

The flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. 

NASA’s Cassini mission will come to a spectacular close on September 15, 2017 after almost two decades in space since its launch in 1997.

A recreation of Huygen's historic descent to Saturn's giant moon Titan in January 2005.

This data visualization represents twenty years' worth of data showing the abundance of life both on land and in the sea. 

This animation glides along the shoreline of Ontario Lacus, the largest lake on the southern hemisphere of Saturn’s moon Titan.

This frame from a video from NASA's Dawn mission shows dwarf planet Ceres in false-color renderings, which highlight differences in surface materials.

A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.

This video from NASA's Dawn mission shows that the gravity field of Vesta closely matches the surface topography of the giant asteroid Vesta.

This artist's concept shows "tides" on Titan raised by Saturn's gravity, as detected by NASA's Cassini spacecraft.

See all the planets, plus mission updates from comet and asteroid missions Dawn and Rosetta.

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

This movie shows a quick succession of multiple products of Titan's surface from the Cassini orbiter and the European Space Agency's Huygens probe.

This sequence of images shows the Sun from its surface to its upper atmosphere and in order of temperature from the first one at 6,000 degrees C on the surface out to about 10 million degrees C.

This movie, made from images obtained by NASA’s Cassini spacecraft of the outer edge of Saturn’s B ring, reveals the combined effects of a tugging moon and oscillations that can naturally occur in ...

Radar Mapping Titan

Hello from Saturn, essentially on the opposite side of the sun as seen from Earth! This annual occurrence called solar conjunction, when Saturn (and Cassini) nearly disappear behind the sun.
