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!
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'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.
Dawn Journal: Approaching Conjunction
Continuing its journey to collect treats in the main asteroid belt, Dawn is making excellent progress toward its July 2011 rendezvous with protoplanet Vesta.
Deep Impact movies of outbursts from Hartley 2
Since comet Hartley 2 -- the target of Deep Impact's November 4 flyby -- is near its perihelion, it's no surprise that it's an active comet with lots of outbursts.

Just a linky post here.
Three days until Deep Impact's encounter with Hartley 2
The week is finally here: Deep Impact flies past Hartley 2, the smallest comet yet to be visited by a spacecraft, on Thursday, November 4 at 13:50 UTC.
Mars Exploration Rovers Update: Spirit Remains Silent, Opportunity Pushes on to Endeavour
For the Mars Exploration Rovers, October was a lot like September, which was a lot like August: Spirit continued hibernating at Gusev Crater or so it appears since the rover didn't phone home; and Opportunity picked up the pace to Endeavour Crater again, setting new driving records and marking more milestones along the way.
Arecibo images show Hartley 2 is elongated
Comet Hartley 2, the target for Deep Impact's close flyby (now just six days away!) made its closest approach to Earth on October 20, at a distance of 17.7 million kilometers.
Pretty picture: Three moons of Saturn
The Cassini Raw Images Website always offers rewards to the browser. This evening I found the raw images necessary to create this color composite, showing the hazy orange moon Titan, the mid-sized icy moon Dione, and the tiny rock Prometheus all at the same time.
An update to the Cassini Tour Page
Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.
Timeline for the Phobos Sample Return Mission (Phobos Grunt)
In mid-October, I attended the First Moscow Solar System Symposium. Its focus was mostly on Phobos science and plans for next year's launch of the Phobos Sample Return Mission (also known as Phobos-Grunt), on which The Planetary Society will be flying the Living Interplanetary Flight Experiment.
A couple of tidbits from today's Deep Impact preview briefing
Today was the press briefing that previewed the upcoming Deep Impact flyby of Hartley 2.
DPS 2010: Pluto and Charon opposition surges, Nix and Hydra masses, Pluto and Eris compositions
An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.
Crack the code for a message from Mars, redux
Waaaay back when Spirit and Opportunity landed on Mars in January 2004, the Planetary Society helped the public participate in the missions with a number of projects, including one where we printed
Congratulations to the IKAROS team for their "8th Web Creation Award"
This news is a little old but worth mentioning: On September 9, the Japanese solar sail mission, IKAROS, won a Web award in Japan for their work to publicize the mission via Twitter.
The 4th MSL Landing Site Workshop: Day 3 - Final Discussion
We wrapped up the landing site workshop on Wednesday afternoon by revisiting each of the four sites and discussing them in turn. Unfortunately, the way that we did this was very disappointing, and made for a frustrating afternoon.
The 4th MSL Landing Site Workshop: Day 3 - Engineering and Safety
With the details of all four landing sites on the table, we started day 3 of the meeting by hearing from the engineers and several scientists about the properties of the ellipses, the risks for landing and the capabilities of the landing system.
Chang'E 2 launches in less than 24 hours, weather permitting
Here are a few photos of Chang'E 2 meeting its launch vehicle in Xichang. It's a beautiful view of the spacecraft.
