Tonight at the Boston Court Performing Arts Center in Pasadena, Jim Bell and Bill Nye will be celebrating the 5th anniversary of the landing of the rovers; Jim will be showing lots of pretty 3D pictures.

A tip of the hat to Ryan over at Martian Chronicles for posting this lovely version of the Santorini panorama, which Opportunity captured just before Mars dipped too close to the Sun in late November of last year.

Hallelujah! For the first time in almost an Earth year, amateur mars mapper Eduardo Tesheiner is able to scratch a tiny little line on his map of the Mars Exploration Rover Spirit's peregrinations across Gusev Crater.

Scott Maxwell is one of those many guys (and gals) at the Jet Propulsion Laboratory who rarely gets his name in the news but who is absolutely indispensable to the success of a space mission. I don't know what his official title is, but whatever it is, it's not as good as the colloquial name given to his position: Rover Driver.

On January 3, 2004, the Mars Exploration Rover Spirit landed on Mars, and I was with the science team at JPL when it happened! I can't believe it's been five years since the successful landing.

As I post this, NASA is holding a press conference in which they are announcing that the Mars Science Laboratory's launch date will be slipped by two years.

At 12 noon EST. I know what the announcement is, but I'm not allowed to tell you! How frustrating is that?!

Mike Griffin started the press conference, and got right down to business announcing the launch delay and indicating that the actuators as well as other technical problems are responsible.

I just heard, via this article at Universe Today, that the sample cache on MSL has been canceled.

The period of Mars solar conjunction has just begun, which means that a host of scientists and engineers whose day jobs entail interaction with the five active Mars spacecraft are getting a five-week break from the daily grind of operations.

I've known about this for a little while but it was finally made public: The list of MSL landing sites had now been trimmed to four.

There was a worrying update posted on the JPL website for Spirit today: an early-season dust storm has darkened its skies enough that its solar panels produced only 89 watt-hours of power yesterday, sol 1,725. Neither rover has ever, ever seen power production levels that low, not even during last year's massive dust storm.

Another day, another drive: on sols 1,693 and 1,695 the Opportunity rover conducted two more lengthy drives to the south, totaling almost 200 meters. On the other side of the planet, Spirit is FINALLY in motion again.

Victoria crater, the site of a Mars year's worth of study, is now far over the horizon, as Opportunity has lately completed a series of very long drives. Opportunity is once again sailing the sand seas of Meridiani Planum.

An article in the September 26 issue of Science neatly explains why only the southern half of Mars is strongly magnetized.

Last week, the Mars Odyssey team announced that their mission is being extended another two years. This mission extension will be slightly different from previous mission phases due to a planned change in the spacecraft's orbit.

NASA is holding a press conference right now regarding MSL and it sounds like they are going to press on and try to achieve the October 2009 launch date.

It's been way, way, way too long since the view from either rover's cameras has changed very much. So I hope you'll join me in a shout of

This image from the HiRISE camera on the Mars Reconaissance Orbiter, shows cracks in the rocks on Mars that once formed the underground plumbing through which groundwater traveled.

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
