Mars Exploration Rover principal investigator Steve Squyres announced on National Public Radio's Science Friday show the next goal for Opportunity, and it's a long, long, long way away: a huge crater about 12 kilometers southeast of its current location, which the team is referring to internally as

Good news, everyone! The jillions of you who have asked me

The next landing site that we heard about was Holden Crater. Holden is a 154 km diameter crater formed early in martian history that happened to fall smack in the path of an extensive fluvial system.

The Eberswalde site is interesting because it is unarguably the best example of a delta on Mars.

The Mawrth Vallis landing site is actually a set of four possible landing ellipses in an area with huge clay mineral signatures that is cut by a meandering outflow channel.

I am sort of breaking my own protocol here by posting about Gale crater before I hear the presentations today, but since we will immediately go into discussion and decision making after it is presented this morning, I figured that it would be good to familiarize you with it now.

For those of you playing along at home, I thought I should point out that most of the presentations so far are posted at the

The discussion and arguments are over! We are just waiting for the last few ballots to be submitted, and then the project science group will start counting them.

It looks like the top three sites are Eberswalde, Holden and Gale.

Miyamoto crater is an ancient crater about 150 km southwest of where the Opportunity rover is right now. The potential landing site has some interesting mineralogy, particularly evidence for phyllosilicate (clay) minerals.

This morning we hit the ground running and heard about a very interesting site: the Nili Fossae Trough. This site would land in a big canyon formed when a block of crust dropped down.

The south Meridiani landing site is a newcomer to the bunch. It was added earlier this summer as a replacement for the north Meridiani site.

We covered a LOT today, so I have decided to split things up. This post will cover the talks in the morning and then I will give each site its own post.

It's almost time! Tomorrow the third Mars Science Laboratory Landing Site Workshop begins!

One year from today, the Mars Science Laboratory will launch. It seems fitting that the workshop during which we choose the final three possible landing sites begins today.

I'm in the airport on my way to California to participate in the third Mars Science Laboratory Landing Site Workshop, so I thought I would take this chance to post my blog entry from day three of last year's workshop.

Today was a marathon of landing site presentations, ranging all over the martian globe, and targeting just about every potentially water-related feature on Mars.

Coming up next week is the 3rd Mars Science Laboratory Landing Site Workshop, where the Mars science community will come together to narrow down the possible landing site choices for MSL.

Clear skies and a warming Sun brightened winter in the southern hemisphere of the Red Planet, giving the Mars Exploration Rovers, appropriately enough, an august month. Opportunity packed up, left Cape Verde in the dust, and made headlines when it roved out of Victoria Crater last Thursday. On the other side of the planet, Spirit picked up the pace of photographing its surroundings for its next big, 360-degree, full color panorama.

It's official: Opportunity is out of Victoria. A news release from JPL stated today that Opportunity has, as of late yesterday (sol 1,634), exited Victoria crater.
