Next week is the annual Fall Meeting of the American Geophysical Union (AGU), an enormous gathering of geoscientists of all varieties that occurs every year at the Moscone Center in downtown San Francisco. AGU is putting increasing effort into making it possible to attend some sessions virtually, and press briefings will be webstreamed, too.

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.
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 "phyllosian", "theiikian", and "siderikian" eras are.
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.
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.
Today I am delighted to welcome India into the ranks of interplanetary travelers: Mars Orbiter Mission has successfully propelled itself onto an interplanetary trajectory, departing Earth forever and setting sail for Mars. Congratulations to India, to the Indian Space Research Organisation, to the mission's scientists and engineers, and to the people of India.
