Happy Christmas on Mars!

Emily Lakdawalla • December 24, 2009

This was so cute I had to repost it -- and record it too.

Watch that front wheel spin!

Emily Lakdawalla • December 17, 2009

Holy cow, look at that right front wheel spin. I am alternately amazed and horrified by this animation.

No, they can't push with the arm to free Spirit

Emily Lakdawalla • December 15, 2009

I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.

A teeny weeny bit of movement in Spirit's right front wheel

Emily Lakdawalla • December 14, 2009

The ever-vigilant Doug Ellison just posted this animation, which really actually does show a teeny tiny bit of motion in the right front wheel. If you don't notice any motion, look closer.

Awesome Mars Express view of Phobos and Deimos together

Emily Lakdawalla • December 11, 2009

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a "mutual event."

Mars Exploration Rovers Update: Spirit Turns Wheels, Opportunity Rests at Rare Martian Rock

A.J.S. Rayl • November 30, 2009

The Mars Exploration Rovers managed to make history and uncover history in November and that put both Spirit and Opportunity in the planetary exploration spotlight during the 71st month of an overland expedition that was supposed to be a three-month tour.

It really looks like the second attempt at driving Spirit out of the trap has had the hoped-for result: some forward progress (maybe about a centimeter), and no evidence for further downward sinking.

Results of the first "Free Spirit" extrication drive, sol 2088: not much, as expected

Emily Lakdawalla • November 17, 2009

Even though all of us rover fans know that Spirit is really, really stuck, I think I'm not the only one who was secretly hoping that today's images downlinked from Spirit would show that the rover had magically popped out of the ground overnight. Of course, she didn't.

Highlights from today's Spirit press briefing

Emily Lakdawalla • November 12, 2009

Since A. J. S. Rayl was also listening in on today's press briefing about the efforts to extricate Spirit from her predicament at Troy, I'll just hit the high points and send you over to her story when she has posted it.

Mars Exploration Rovers Update: Spirit Begins Extraction Process

A.J.S. Rayl • November 12, 2009

On Monday, November 16, 2009, Mars Exploration Rover Spirit will begin the much-anticipated, weeks-long process of extricating itself from a patch of powdery soil that stopped it in its tracks six months ago. It will begin by driving forward to the north, following its tracks out, even though its right front wheel is broken and immobilized.
