Release of Probe

Bob Anderson describes his work as a geologist who helps design and uses robots to collect data about Mars.

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...

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

Orange and white stripes slide against each other, and huge oval storms  gyrate in the NASA's Cassini spacecraft's first color movie clip of Jupiter.  

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 ...

On June 30, 2004 (PDT), as mission controllers at NASA’s Jet Propulsion Laboratory held their collective breath, the international Cassini-Huygens mission successfully arrived in orbit around Saturn.

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

The interaction of the solar wind with the Martian moon Phobos creates a complex electrical environment that could impact future exploration.

This animation of Vesta is made from images taken with Dawn's framing camera.

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. 

Glowing like a neon lasso, Saturn’s aurora is seen spinning above Saturn’s north pole over the course of most of a Saturn day in this movie made from multiple images taken by the ultraviolet imagin...

A large sunspot was the source of a powerful solar flare and a coronal mass ejection (Sept. 6, 2017). The flare was the largest solar flare of the last decade. For one thing, it created a strong sh...

NASA's Cassini spacecraft, in orbit around Saturn for nearly 13 years, is beginning its Grand Finale — and it's thanks to some Crazy Engineering!  A team of engineers called astrodynamicists use ma...

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

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

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.

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

The Sun emitted a significant solar flare on Dec. 19, 2014.  

This animated movie shows the simulated solar wind velocity from March 21 to May 10, 2013. 

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

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.

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

The beauty and spectacle of celestial motion is captured in this short movie of a moon shadow darting across Saturn's rings.

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.

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.
