I have a couple of updates on my post from yesterday: confirmation that Chang'E 2 is indeed gone from L2, and more specifics on encounter dates with Toutatis.
According to a Chinese spaceflight forum, Chang'E program chief scientist Ouyang Ziyuan recently announced that Chang'E 2 has departed the Sun-Earth L2 point and is now en route to asteroid 4179 Toutatis!

I made myself a cheat sheet to many of Vesta's distinctive-looking craters, and also wrote down a list of the major dates in the timeline of Dawn's exploration of Vesta.

A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.
With a new CCD camera configured to shoot rapid, short exposures bought with a Planetary Society Shoemaker NEO Grant we caught near-Earth asteroid 2012 DA14.

A new installment of our "Snapshots" video series examines the threat posed by asteroids on collision courses with our home planet. Emily Lakdawalla explains why it's so important to find, understand and learn to deflect these potential civilization enders.

�On June 30, Dawn stopped thrusting for a full Vestian day -- five hours and 20 minutes -- and just watched the asteroid rotate. But unlike the previous observations, they used all of Dawn's�color filters�to acquire the best-ever color photos of the lumpy world.

A report on the press briefing and talks from the Fall 2011 American Geophyisical Union meeting about the data on Vesta collected so far by Dawn.

Last week JPL released two animations of asteroid 2005 YU55 made from the radar data acquired by Goldstone's 70-meter radio dish.

Anticipating the close flyby of asteroid 2005 YU55 yesterday, the Jet Propulsion Laboratory invited media to tour Goldstone, one of three facilities that make up NASA's Deep Space Network. I've always wanted to see these massive radio dishes up close, so I jumped at the chance!

Unless you've been living under a rock you've probably heard that there is a relatively large (400-meter) asteroid passing closer to Earth than the orbit of the Moon today -- in just a few minutes, as a matter of fact.

I'm nearly two weeks late getting to this news but better late than never, right? There was a press briefing from the Dawn mission at the Geological Society of America (GSA) meeting on October 12.

With little fanfare, the Dawn mission continues releasing a new picture from Vesta every day. This one is definitely my favorite among their recent releases, a closeup on one of Vesta's strange streaky bright craters.

Today was (is) the last day of the Division of Planetary Sciences / European Planetary Science Congress meeting in Nantes, France.
