Opportunity's poking at Marquette Island; Cassini's catching dancing moons

Emily Lakdawalla • November 18, 2009

Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.

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.

Planetary Radio Q and A: Are meteorites on Mars actually interesting?

Emily Lakdawalla • November 09, 2009

The Mars Exploration Rover Opportunity has been studying a lot of meteorites. That made me wonder, why study meteorites on Mars when we can study them in hand on Earth? How are Mars meteorites interesting?

She moves! "First drive sequence in 145 sols" for Spirit

Emily Lakdawalla • November 08, 2009

It's been an awful long time since we've seen one of these from Spirit: an animation of four Navcam frames documenting motion!

Mars Exploration Rovers Update: Spirit Overcomes Setbacks and Waits for Extraction Orders, Opportunity Takes a Magical Meteorite Tour

A.J.S. Rayl • October 31, 2009

The Mars Exploration Rover mission logged another textbook-rewriting month in October 2009 with more discoveries of geologic gems, new robot achievements balanced with equal amounts of challenges and frustrations overcome, topped off with special honors.

Opportunity's world of dunes and rock

Emily Lakdawalla • October 16, 2009

Opportunity's been making tracks lately, with brief stops to check out a couple of meteorites. I thought this view of its surroundings on sol 2,034 (a couple of days ago) was neat.

It would appear that Opportunity has stumbled upon another meteorite

Emily Lakdawalla • October 02, 2009

I wonder if this came from the same original body as Block Island, or if Meridiani is the kind of slowly deflating landscape that accumulates meteorites at its surface, like the ANSMET meteorite hunting spots in Antarctica?

Mars Exploration Rovers Update: Embedded Spirit Waits Exit Approval, Opportunity Celebrates New Mars Year with New Record

A.J.S. Rayl • September 30, 2009

From notable achievements and new discoveries to trials and tribulations and harbingers of hope, the Mars Exploration Rovers seemed to experience the gamut on the Red Planet this September, their 69th month on an expedition that originally set out back in 2004 for a three-month tour.
