Voyage of Discovery

Pan Found!

Rotating asteroids have a tough time sticking to their orbits. Their surfaces heat up during the day and cool down at night, giving off radiation that can act as a sort of mini-thruster.

This animated graphic shows how Saturn and its moon Enceladus are electrically linked.

No one really knew what Vesta looked like until NASA’s Dawn spacecraft decided to drop in on it. Now, images taken by the spacecraft have been stitched together to create a virtual flyover of the j...

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 graphic shows in a series of three images how Saturn's rings, after they became tilted relative to Saturn's equatorial plane, would have transformed into a corrugated ring.

The history-making Viking 1 mission launched 35 years ago.

This movie shows Mercury's globe as it rotates. 

Two crescent moons dance around Saturn as far-off Dione slips behind its sibling moon Rhea.

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

A shortened, 54-second version of Cassini's Grand Finale animation showing the spacecraft's final moments.

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

The Helioseismic Magnetic Imager (HMI) aboard the Solar Dynamics Observatory takes a series of images every 45 seconds in a very narrow range of wavelengths in visible light of the solar photospher...

What’s the latest news from Mars? NASA’s InSight lander and MarCO CubeSats are on their way to the Red Planet, a tiny helicopter will hitch a ride with the Mars 2020 rover mission, and Curiosity’s ...

Clara, Sugar Plum Fairy, move aside. Saturn's moons give Tchaikovsky's classic ballet, "The Nutcracker," a graceful new spin in this video compiled from some 61 images taken by the Cassini spacecra...

Ceres' lack of giant impact basins presents a puzzle to scientists.

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 ...

Project Scientist Linda Spilker and Mission Planner Molly Bittner answer questions about Cassini's Ring-Grazing orbits during this Jan. 30, 2017 Facebook Live event. 

As Titan Turns

This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and ...

Cassini mission leads Earl Maize and Linda Spilker talked about the spacecraft's epic journey and science - and the exciting two-part grand finale.

This animation shows "beacons" of hot air seen in the infrared that appeared during a great springtime storm on Saturn from January 2011 to March 2012. 

This colorized flyover movie from NASA's Cassini mission takes viewers over the two largest seas on Saturn's moon Titan and nearby lakes.

In this movie, strung together from a series of images provided by the framing camera on NASA's Dawn spacecraft, we see a full rotation of Vesta, which occurs over the course of roughly five hours.
