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!

Evidence continues to pile up that the Rio Vichada structure in Colombia is indeed the largest impact structure in South America.
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.

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 spent much of the past week attending the Caltech Space Challenge, a student-organized international competition to design a human mission to a Near-Earth asteroid. It was a great week, and one of the most positive, upbeat and hopeful programs I have participated in concerning the future of space exploration.

NASA funds regular meetings of scientists who work on different parts of the solar system to provide scientific input into NASA's future plans. These "analysis groups" are known by their acronyms, all of which sound kind of horrible, but none has quite as terrible-sounding an acronym as "SBAG," usually pronouced "ess-bag," the Small Bodies Assessment Group.

In spite of some bad weather conditions during the first part of this year, the new camera bought with funds from a Planetary Society Shoemaker Near Earth Object grant helped us to discover and confirm ten new near-Earth objects.

One nice thing about the Planetary Defense conference is that I not only get to talk with the NEO community of experts all in one place and hear their new science, but I also get updates on projects the Planetary Society has funded.

A terrific set of Goldstone radar images of a good-sized near-Earth asteroids named 2010 JL33 was posted to the JPL website yesterday. They also posted a movie version but something about these pixelated radar image series absolutely begs for them to be displayed as an old-school animated GIF, so I made one.

It was January of 2004 when the elegant curve of the Vichada first caught the attention of geologist Max Rocca of Buenos Aires. Could the course of the river have been shaped by the circular outlines of an impact crater? Rocca decided to find out.
