Crazy Engineering: Ion Propulsion for the Dawn Mission

This graphic shows a 3-D model of 98 geysers whose source locations and tilts were found in a Cassini imaging survey of Enceladus' south polar terrain by the method of triangulation.

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

Hear about what we know about Titan topics that were investigated early in Cassini’s mission. Learn what questions have baffled and perplexed Cassini scientists for a long while (cough cough cryovo...

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.

Jupiter is at its biggest and brightest, Mercury and Mars appear ultra-close after sunset for two nights and how you can observe the Moon's tilted orbit.

This image shows that NASA's Dawn mission detected abundances of hydrogen in a wide swath around the equator of the giant asteroid Vesta. The hydrogen probably exists in the form of hydroxyl or wat...

These false-color mosaics from NASA's Cassini spacecraft chronicle the changing appearance of the huge storm that developed from a small spot in Saturn's northern hemisphere.

Have you ever seen a meteorite streaking across the sky? If so, you may very well have seen part of the asteroid, Vesta!

Part of the shadow of Saturn's moon Mimas appears as if it has been woven through the planet's rings in this unusual series of images from Cassini.

Pan Found!

Annette and Alden Tombaugh, the children of Clyde Tombaugh, remember their father and his discovery of Pluto.

This audio clip was created from radio signals received by the radio and plasma wave science instrument on the Cassini spacecraft.

Since the 1960’s, scientists have suspected that frozen water could survive in cold, dark craters at the Moon’s poles. 

This animation, from Cassini's navigation team, shows the spacecraft's final orbits in 2016 and 2017. 

This spectrogram and video show a changing pattern of radio waves from Saturn known as Saturn Kilometric Radiation, as detected by NASA's Cassini spacecraft.

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.

This colorized movie from NASA's Cassini mission shows a polar projection of the curious six-sided jet stream at Saturn's north pole known as "the hexagon" in the infrared.

This movie is made up of over 600 consecutive images taken on March 16 to March 18, 2007, with the Cassini Magnetopsheric Imaging Instrument's ion and neutral camera.

For hundreds of years, this gaseous giant planet appeared shrouded in colorful bands of clouds extending from dusk to dawn, referred to as zones and belts.

This is a compilation of the Saturn hexagon movies released on Dec. 5, 2013.

Watch the NASA-JPL press briefing announcing Cassini's final orbits recorded at JPL on April 4, 2017.

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.

A quick look at how a Bistatic Observation works.
