Mars Exploration Rovers Update: Opportunity Emerges from Solar Conjunction to Wrap-Up Work on Matijevic Hill

A.J.S. Rayl • May 02, 2013 • 1

As the Mars Exploration Rover (MER) team waited out solar conjunction, Opportunity spent most of April atop the western rim of Endeavour Crater, conducting a chemical analysis of an ancient waterborne vein on Matijevic Hill. It was by the book until the last week of the month when the robot field geologist suffered an electronic "hiccup" known as a warm re-boot, and went into auto mode, a kind of safe mode when something doesn't go right.

No Place Like Home

Mars and Earth share a truly striking family resemblance, but there's no mistaking which one is home.

Blast from the Past: Spirit's tracks at the "End of the Rainbow"

Emily Lakdawalla • April 09, 2013 • 3

Doug Ellison shared this lovely panorama via Twitter over the weekend. It's from the Mars Exploration Rover Spirit, taken back in 2004. The drunken path in the foreground is a visual record of just how exciting it was for Spirit to have finally made it to the Columbia Hills, and to rocks that were not fragments of basalt.

Mars Exploration Rovers Update: Opportunity Hunkers Down for Solar Conjunction, Final Science on Matijevic Hill

A.J.S. Rayl • April 02, 2013 • 5

As the Mars Exploration Rover (MER) mission trekked further into its tenth year of exploring the Red Planet, Opportunity spent the month of March finishing up its science investigations on Matijevic Hill.

Field Report From Mars: Sols 3237-3262 - March 4–29, 2013

Larry Crumpler • March 29, 2013

Flash memory or computer problems oddly occurred on both Curiosity and Opportunity around Feb 27. One possibility is that a large solar flare resulted in radiation at Mars sufficient to temporarily corrupt the memory on both rovers.

LPSC 2013: Sedimentary stratigraphy with Curiosity and Opportunity

Emily Lakdawalla • March 20, 2013 • 4

A mind-boggling quantity of information is being presented at the Lunar and Planetary Science Conference. In my first report from the meeting, I try to make sense of the Curiosity and Opportunity sessions.

Mars Exploration Rovers Update: Opportunity Begins Wrapping Science on Matijevic Hill

A.J.S. Rayl • March 06, 2013 • 1

As February turned to March, Opportunity was conducting some of its final science investigations on Matijevic Hill, the MER team was making preparations for the robot field geologist's trek south for the next winter, and the Mars Exploration Rovers mission was checking off another month of exploration.

Field Report From Mars: Sol 3220-3236 - March 1, 2013

Larry Crumpler • March 01, 2013

Opportunity completed the observations of the outcrop noted in the previous report and has now moved back down slope.

Webcast Tonight! Planetary Scientist and Society President Jim Bell

Mat Kaplan • February 20, 2013

Professor Bell's topic is "Exploring Mars, the Moon, Asteroids, and Comets with Rovers and Landers," and there is no one better to talk about this subject.

Field Report From Mars: Sol 3215-3219 - February 6-13, 2013

Larry Crumpler • February 13, 2013

We have been seeing lots of small light-colored veins crossing through the outcrops here on Matijevic Hill, and we have tried to get a handle on the composition of these veins by doing multiple offsets with the APXS. It appears that the small veins are calcium sulfate, as best we can determine.
