In which I finally get around to writing about a paper published last August: Enceladus' plumes sometimes spout more and sometimes spout less, depending on where Enceladus is in its orbit. This discovery was enabled by Cassini's longevity at Saturn, and we'll be able to follow up on it, as long as Cassini is allowed to complete its mission.

Chang'e 3 is just about to land on the Moon, and the LADEE orbiter has begun a new science mission there, while Lunar Reconnaissance Orbiter is still producing amazing images.
Comet ISON Wrap Up
A Tail of Cat-Possums and the Undead

Comet ISON captivated our world, and many of our world’s robotic emissaries for many months. But, alas, poor ISON is dead -- again. Here I wrap up our enthusiastic coverage of this multi-morphing zombie comet that tried to survive and re-survive as it came within one solar diameter of the Sun.
Comet ISON reached perihelion at 18:25 UT (10:25 PT) on November 28. It's an event that's was watched around the world, accompanied by tons of commentary and streams of photos. We will update this blog entry periodically with links to all the resources that we hear of for following the comet's progress.
Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.
When comet ISON passed through perihelion last week, solar observing spacecraft had a ringside view. Here are several animations of ISON's perilous passage from the SOHO and two STEREO spacecraft.
On December 1 at 17:30 UTC, Chang'e 3 launched atop a Long March 3B rocket on a direct lunar transfer trajectory. It is scheduled to enter orbit December 6 and land December 14. The rocket was equipped with cameras that recorded thrilling video of the launch and final departure of the probe.
Bright and early this morning, we NASA Social folks met at the Kennedy Space Center Visitors Complex for a tour of the space shuttle Atlantis. This is the first shuttle I've seen in person, and it was a stunning sight to see.

The Jet Propulsion Laboratory announced today that the geologists on both Mars rover teams -- Opportunity and Curiosity -- have named landmarks at their field sites after the late Bruce Murray.
It took months of work (and no wonder) but the wait was worth it: here is Cassini's spectacular view of Saturn, captured on July 19, 2013, as Cassini passed through Saturn's shadow. If you're a little confused by the image, I'm here to help: I've posted a video explainer.
As India's Mars Orbiter Mission continues to pump up the altitude of its orbit around Earth, NASA's MAVEN is making final preparations for its direct-to-Mars launch. All is proceeding acccording to schedule toward its November 18 launch at 1:28 EST / 10:28 PST / 18:28 UTC.
Can features on Neptune be observed by amateur astronomers? For years, the Hubble Space Telescope and some professional terrestrial observatories have been revealing incomplete belts and spots on the surface of Neptune. Now, spots have been imaged by amateurs.

On Sunday, the shadow of the Moon passed across Africa and the Atlantic Ocean. This was the last solar eclipse of the year. The Elektro-L satellite was able to observe the eclipse, and we can see the darkness of the lunar shadow covering Africa.
