It takes spinning reaction wheels and rockets firing for mere seconds to keep the Cassini probe on course in orbit around Saturn.
NASA's orbiter Cassini will make a series of decreasing orbits that will end in a fiery death dive into Saturn's atmosphere in September. This deliberate termination of a still serviceable spacecraft is to comply with "planetary protection" protocols, designed to minimise the risk of depositing stowaway Earth microbes into an environment where they might be able to reproduce.
NASA's Cassini spacecraft peers toward a sliver of Saturn's sunlit atmosphere while the icy rings stretch across the foreground as a dark band.
During its journey, Cassini has made many discoveries, including a global ocean with hydrothermal activity within Saturn's moon Enceladus, and vast seas of liquid methane on the planet's largest moon, Titan. Cassini began the final, dramatic phase of its mission,...
NASA's Cassini spacecraft has been hanging out around Saturn and its moons for over a decade and a half now, and it's seen a lot of really awesome sights during its visit. The planet's moon of Titan has gotten its fair share of attention...Show More Summary
The Cassini spacecraft has sent back a ton of images and data to NASA and Earth during its time in the outer solar system. Here’s a look back at some of the most amazing photos.
From high above Saturn's northern hemisphere, NASA's Cassini spacecraft gazes over the planet's north pole, with its intriguing hexagon and bullseye-like central vortex.
NASA's Cassini spacecraft has beamed back some stunning views of Saturn's rings, taken on June 4, as the probe sped through the 1,500-mile (2,400-km) gap separating the gas giant's uppermost cloud layers and innermost rings. With the...Show More Summary
One of NASA's greatest spacecraft will call it quits on September 15, 2017. The Cassini spacecraft has made countless discoveries during its sojourn to Saturn and its surrounding moons. It has also sent back nearly 400,000 images, many...Show More Summary
(Cornell University) Enceladus -- a large icy, oceanic moon of Saturn -- may have flipped, the possible victim of an out-of-this-world wallop. While combing through data collected by NASA's Cassini mission during flybys of Enceladus,...Show More Summary
Saturn's icy, ocean-bearing moon Enceladus may have tipped over in the distant past, according to recent research from NASA's Cassini mission. Researchers with the mission found evidence that the moon's spin axis -- the line through the north and south...
A new study based on data from NASA's Cassini spacecraft suggests that the Saturnian moon Enceladus tipped onto its side after an asteroid collision led to the formation of the satellite's famous tiger-striped terrain. The fracturesShow More Summary
Saturn's icy, ocean-bearing moon Enceladus may have tipped over in the distant past, according to recent research from NASA's Cassini mission. Researchers with the mission found evidence that the moon's spin axis—the line through the north and south poles—has reoriented, possibly due to a collision with a smaller body, such as an asteroid.
As Cassini counts down its final days at Saturn, NASA looks back at a stunning image of moon-created ring waves.
A giant hexagon is swirling at Saturn's north pole, and scientists don't fully understand it, despite years of observation by NASA's Cassini spacecraft. The hexagon — a jet stream that traps an entire polar weather system — is as wide as two planet Earths. Show More Summary
Lately, NASA's Cassini orbiter has been delivering some stunning photos from its trips around Saturn, but that's not the only fancy camera floating around a nearby planet. The agency's Juno spacecraft has been hanging out around Jupiter...Show More Summary
NASA's Cassini orbiter was the first to deliver a really clear look at the eye-catching, hexagonal storm swirling on Saturn's north pole, so it's only fitting that the craft has now delivered a photo of the peculiar phenomenon that adds a new layer of awe. Show More Summary
A swirling NASA animation shows the shift in Saturn's north pole colors as seen by the Cassini spacecraft.
NASA's Cassini spacecraft still has a few months to go before it completes its mission in September, but the veteran Saturn explorer reaches a new milestone today. Saturn's solstice—that is, the longest day of summer in the northern hemisphere and the shortest day of winter in the southern hemisphere—arrives today for the planet and its moons. Show More Summary
For the last 13 years, NASA's Cassini spacecraft has spied on Saturn and its many moons. Turns out, this region of space could hold the greatest secrets of our solar system. Here are 5 of the most fascinating discoveries Cassini has given us so far. Follow Tech Insider: On Facebook Join the conversation about this story »
