Deep Impact at Hartley 2: Two weeks after the flyby
Today the Deep Impact/EPOXI science team held a press briefing that followed up on their very successful flyby of two weeks ago, a status report on what they can say so far about the science that's coming out of the encounter.
A little more information on the Hayabusa samples from Itokawa
Since I posted an update Monday about JAXA confirming extraterrestrial samples in the Hayabusa sample return capsule, JAXA has posted an English-language version of their press release, which contains a bit more information.

In which I finally write up last week's Deep Impact Hartley 2 press briefing
On Thursday, November 4, at 13:50 UTC, Deep Impact flew within 700 kilometers of comet Hartley 2. Hartley 2 is the smallest and most active of the five comets that have been directly by a spacecraft, and the first to be visited within the lifetime of its discoverer.

Fly over Mars
Adrian Lark has posted several new flights over gorgeous Martian landscapes to his Youtube channel. My favorite of his recent ones is this dive into Zumba crater.
Hartley 2 compared to other comets, and in motion 3D
I had to catch up with tasks left undone at home today and didn't have time to write up my notes from the Hartley 2 press briefing, for which I apologize. I'll leave you for the weekend with three cool Hartley 2 pictures.
Hartley 2's jets
It was a very happy set of scientists, engineers, managers, and administrators who filled the Jet Propulsion Laboratory's Von Karman auditorium this afternoon to do the postgame show on Deep Impact's flyby of Hartley 2.
Animation of the five closest-approach Hartley 2 images
Those of you who follow my blog must have known this was coming: now that I got all five new Deep Impact images of Comet Hartley 2 posted and explained, I had to make an animation. Here they are.
Five close-approach images of Hartley 2 by Deep Impact, with commentary
Here's the five close-approach images of Hartley 2 captured today, November 4, 2010, by the Deep Impact spacecraft, collected into one file. Boy, do these images reward close examination!
Close approach images of Hartley 2!
What a dramatic and cool photo! An asteroid with two lobes like Borrelly, lumpy and bouldery like Itokawa, with gorgeous active jets, dramatically lit. Well done, Deep Impact team!
Deep Impact successfully passed closest approach, signal reaquired, data downlinking
Just a very brief update to congratulate the Deep Impact team on what was apparently a successful flyby of Hartley 2!
Deep Impact's encounter with Hartley 2 is beginning; flyby in 17 hours
According to the mission timeline, the Deep Impact high-resolution observations of Hartley 2 are beginning in just a few minutes, at 20:50 according to the clock on the spacecraft.
