Continuing its journey to collect treats in the main asteroid belt, Dawn is making excellent progress toward its July 2011 rendezvous with protoplanet Vesta.

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.

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.

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.

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.

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.

Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.

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.

Today was the press briefing that previewed the upcoming Deep Impact flyby of Hartley 2.

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.

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

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.

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.

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.

Here are a few photos of Chang'E 2 meeting its launch vehicle in Xichang. It's a beautiful view of the spacecraft.

I left the first day of the Fourth Mars Science Laboratory Landing Site Community Workshop on Monday just as they were getting in to the site-specific presentations. I left with no concern that I'd miss anything, though, because I knew that once he got done presenting his own work on Gale Crater, Cornell grad student Ryan Anderson would be taking notes and blogging the presentations on the other three sites.

As Opportunity picked up the pace to Endeavour Crater this month and crossed the halfway point on the long journey from Victoria Crater and Spirit continued sleeping in hibernation mode, the Mars Exploration Rovers chalked up their 81st month of what was supposed to have been just a three-month tour of the Red Planet.

Two weeks ago Mars Reconnaissance Orbiter and Mars Climate Sounder (MCS) started a four-week campaign to support entry, descent, and landing phase for the next Mars rover, Mars Science Laboratory (or
