SEE IT NOW: The Planetary Society's CEO, Bill Nye the Science Guy, joined Director of Projects Bruce Betts for a live webcast as 2012 DA14, a 45-meter asteroid, was passing Earth. Bill and Bruce also marveled at video of the meteor burst high over a city in Russia.
A large meteor streaked through the skies above Russia on the morning of Feb 15th, causing a deafening sonic boom that shattered windows and injured hundreds.
Planetary Society Hangout: Jan 24th, 2013 - Hunting Asteroids with Gary Hug
Thursday at noon PST/3pm EST/20:00 UT

Gary Hug is an asteroid hunter. He scans the skies every night looking for new near-Earth objects and refining orbital measurements for existing ones. Join Casey Dreier and Dr. Bruce Betts as they interview Gary Hug about his work and his recent discovery of a new NEO on January 7th.
Last week at a meeting of NASA's Small Bodies Assessment Group (SBAG), Han Li of the Chinese Academy of Sciences gave a lengthy presentation on Chang'E 2. Her presentation included a new sequence of photos from the December 13 Toutatis flyby.
Using a Planetary Society provided camera, Gary Hug in Kansas, USA discovered Potentially Hazardous Asteroid 2013 AS27 on Jan. 7, 2013. Shoemaker winner Bob Holmes provided the first follow up observations of this 140m-310m wide asteroid.
My collage of all the asteroids and comets visited by spacecraft is probably the single most popular image I have ever posted on this blog. I've now updated it to be in color and to include Toutatis.
The Chang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh my goodness, did they succeed. These, in combination with the incredible radar images still being acquired from Goldstone and innumerable optical observations, make Toutatis one of the best-studied asteroids in the solar system.
Near-Earth asteroid 4179 Toutatis will be passing within 7 million kilometers of Earth on December 12. Both radio telescopes and the Chang'E 2 spacecraft will be acquiring images.
Calling (Really Serious) Asteroid Hunters
New Shoemaker NEO Grant Call for Proposals
I am happy to announce a new call for proposals for The Planetary Society’s Gene Shoemaker Near Earth Object (NEO) grant program, which is celebrating its 15th Anniversary. Proposals are due Feb. 4, 2013.
PlanetVac: Sucking Up Planetary Regolith
A New Planetary Society Project
Learn about the Planetary Society’s newest project: PlanetVac, with Honeybee Robotics, aims to prototype and test in a huge vacuum chamber a new way to sample planetary surfaces that could be used for sample return or for in situ instruments.
Continuing my writeup of notes from last week's Division for Planetary Sciences meeting: presentations on the risks of future asteroid impacts. How much risk do we face, and what are the appropriate actions to take in the face of that risk?

Gary Hug used his Shoemaker NEO grant provided camera to find 2012 SY49 which flew by Earth at about two lunar distances last week. The tens of meters wide asteroid is a low-probability possible Earth impactor in the future.

The Shoemaker NEO Grants at 15
The Planetary Society Shoemaker NEO grants celebrate their 15th anniversary of helping to find and track near Earth asteroids. Here's a quick review of the program, and updates on our four multiple-grant winners.
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.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
