OSIRIS-REx Orbits

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

This movie sequence shows highlights of the Cassini spacecraft's Sept. 26, 2005, flyby of the odd, icy moon Hyperion.

On Nov. 30, 2016, NASA's Cassini mission begins a daring set of ring-grazing orbits, skimming past the outside edge of Saturn's main rings.

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.  

What can you see in the April sky? The Moon visits Mars in the evening, and later joins Saturn and Jupiter for a spot of tea. Also, how to find Polaris, the North Star.

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.

Mark Hofstadter describes the lure of science -- of discovering something new -- and his path to becoming a planetary scientist.

OSIRIS-REx Prepares to Grab Sample of Asteroid Bennu

Hi, Everyone! My name's Morgan. My favorite topic is Enceladus.

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

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.

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

The Dawn spacecraft visited the asteroid 4 Vesta for the time period May 3, 2011 to Sept. 5, 2012.

This mosaic strip – extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14, 2015 – now includes all of the highest-resolution images taken by the NA...

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

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

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.

As Titan Turns

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...

Flight across Titan

What's Up for August? This month our main focus is the Perseid meteor shower.

This animation demonstrates how deformation in the icy surface of Europa could transport subsurface ocean water to the moon’s surface.

Vesta and Ceres reside in the boundary area of the asteroid belt, where the composition of bodies changes from being almost dry to showing the effects of hydration.
