Transmitting images all the way down, China's Chang'e 3 lander successfully arrived on the lunar surface at 13:11:18 -- half an hour before the scheduled landing time. Rover deploy is set for a few hours later.

Here it is! Animated gifs, composed of screen grabs from Chinese state television, of the Yutu rover rolling on to the lunar surface. This was a replay, but it was no less thrilling for that; the actual rollout happened at 20:40 UT (12:40 PT). Six wheels on soil! Woohoo!

We've waited long enough, Europa cries out for exploration and discovery. It's time to heed that cry.

2013 has been a rather exciting year for Europa scientists. Today's exciting news: the Hubble Space Telescope discovery of water vapor plumes from the south pole of this icy moon.

A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.

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.

In a Martian first, the Curiosity science team has measured the age of a Martian rock, in two totally different ways. They presented the result at the 2013 meeting of the American Geophysical Union.

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.

I'm returning to the deep dive into the literature that began with articles about lunar basins and then explored the geologic time scales of Earth, Moon, and Mars. Now it's time to catch up to the last decade of Mars research and learn what

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.

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.

Although winter took hold at Endeavour Crater in November, Opportunity pressed on, climbing up Murray Ridge and driving into a clay mineral hunting ground as the Mars Exploration Rovers mission cruised another month closer to celebrating its 10th Earth year of surface operations with myriad events throughout January 2014.

Two Hangouts bookended comet ISON's perihelion, hosted by Chuck Beuter of Comet Festival South Bend. On November 25, it was I and Ron Kaitchuck. On December 2, Alex Filippenko and I discussed what happened to the comet over Thanksgiving.

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.
