Release of Probe

Keeping a close watch on the outer portion of Saturn's B ring, NASA's Cassini spacecraft records the complex inward and outward movement of the edge of the ring.

This artist's concept shows the European Space Agency's Huygens probe descent sequence.

MESSENGER captured this departure sequence of Venus after a close flyby of the planet in 2007.

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.

Bands of eastward and westward winds on Jupiter appear as concentric rotating circles in a movie composed of Cassini images which have been reprojected to appear as if the viewer were floating over...

Everyone likes to check the weather in a far away destination before they travel there. This is especially true for spaceflight, where the destination may be where no one has gone before.

On unexplored worlds, the sound of science is a harmonious melody of chimes, clicks and mechanical whirrs.

With Cassini’s exploration of Saturn coming to a dashing end in a few months, the mission team scheduled an “All Cassini Plus Alumni” group photo on Wednesday, June 21,2017 to commemorate the event...

On March 6, the Dawn spacecraft will slip into orbit around Ceres, a dwarf planet located in the main asteroid belt.

The bright crescent of Saturn's moon Enceladus slides past distant Rhea in this mutual event, or occultation, movie from Cassini.

Sir Arthur C. Clarke's video greeting to NASA's Jet Propulsion Laboratory for Cassini's first close Iapetus flyby in 2007.

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.

This is a computer simulation of the final stage of the growth of a "clump" in Saturn's rings.

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

Eleven years in the life of the Sun, spanning most of solar cycle 23.

This movie from Cassini, made possible only as Saturn's north pole emerged from winter darkness, shows new details of a jet stream that follows a hexagon-shaped path and has long puzzled scientists.

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

A simulated flyover of the most intriguing landmarks on giant asteroid Vesta, as seen by NASA's Dawn spacecraft.

This movie, comprised of several detailed images taken by Cassini's radar instrument, shows bodies of liquid near Titan's north pole.

See highlights from the scene at JPL on April 26-27, 2017, and some of the first raw images the spacecraft sent back from its closest-ever look at Saturn’s atmosphere.

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...

Ben Holt tells how he fell in love with the ocean as a teenager and how that lead to a career as a research scientist.
