A Naked Titan Revealed by 13 Years of Cassini Data

Saturn’s largest moon Titan boasts the distinction of being the only moon in the solar system to have a thick atmosphere…so thick, in fact, that its surface is perpetually hidden from our view—but not from the view of the Cassini spacecraft’s infrared cameras! Cassini, now over ten months gone after its Sept. 2017 plunge into…

Spacecraft Down: Cassini is Gone

It’s official: Cassini’s mission at Saturn is over. Today, at 6:31 a.m. EDT (10:31 UTC), Cassini entered the atmosphere of Saturn. A little over a minute later it sent its final transmission back to Earth before succumbing to the physical forces of entry. That signal, Cassini’s last piece of data, ended at 7:55 a.m. EDT…

It’s Time to Say Goodbye to Cassini

Well, the day has come. Today is the last full day that NASA’s Cassini spacecraft will exist, and in fact right now it is on its final path—a grand soaring arc that will send it down into the atmosphere of Saturn itself on the morning of Friday, Sept. 15. It will be the closest to the…

It’s Cassini’s Final Month.

Yes, it’s true. As of today, August 15, NASA’s Cassini spacecraft has less than 31 days—one full month—left in operation and, sadly, its existence. On September 15, 2017, Cassini will end its mission with a controlled dive into Saturn’s atmosphere…a journey that it will not long survive. But up until the very end Cassini, which…

A Departing View From Cassini After Clearing the Gap

Cassini did it again! On May 2-3, 2017 the spacecraft made its second “ring dive” pass of Saturn, passing through the clear space between the innermost edge of the ring system and the planet itself. The animation above shows a view from Cassini looking back toward Saturn on its outbound flight on May 3, just a…

Get Ready for Cassini’s Glorious Grand Finale

The end is near. On September 15, 2017, NASA’s Cassini spacecraft will end its mission as well as its very existence with a plunge into the atmosphere of the very planet it has been orbiting since June 2004. It’s a maneuver intended to protect the pristine environments of Saturn’s icy moons, some of which harbor…

Cassini Pinpoints a Propeller in Saturn’s Rings

NASA’s Cassini spacecraft captured these images of a propeller in Saturn’s A ring on Feb. 21, 2017. These are the sharpest images ever taken of a propeller and reveal an unprecedented level of detail. This propeller is nicknamed “Santos-Dumont” after the Brazilian-French aviator who is hailed as the father of aviation in Brazil. The February 2017 imaging…

Cassini Mission Highlight: Mile-High Spikes Along Saturn’s B Ring

A field of spike-like structures rise up over two miles from the outer edge of Saturn’s B ring in the amazing image above, captured by Cassini during Saturn’s spring equinox in August 2009. These pointy perturbations are caused by the gravitational nudges of tiny (~1/2 mile) embedded moonlets traveling around Saturn within the B ring, causing fine icy…

Share Your Love of Cassini and Saturn with the World

Even if you’re feeling inundated by Valentine-themed everything at the moment, if you love space and you’re at all creative you’re definitely going to adore this. With Cassini in the final months of its 13 years at Saturn, NASA wants you to share your love of the spacecraft, its discoveries, and the ringed planet and its fascinating…

Intricate Details of Saturn’s Rings Are Revealed in Latest Cassini Images

Like those fractal designs that were so popular in the ’90s Saturn’s rings reveal finer and finer structures the nearer Cassini gets, now in the final year of its mission. Recent images from the spacecraft, captured in December 2016, show groove-like density waves and skyscraper-sized clumps within the planet’s icy rings—and it’s just a hint at what…

Cassini Has Just Taken the Best Picture of Daphnis Yet!

Hello, Daphnis! On January 16, 2017, the Cassini spacecraft captured the best photo yet of Daphnis, a 5-mile-wide shepherd moon that orbits Saturn inside the Keeler Gap at the outermost edge of the A ring (and also just so happens to be my personal favorite moon of Saturn!) The raw image arrived on Earth today, and…
