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

A.J.S. Rayl • April 02, 2013

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

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

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

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.

Mars Exploration Rover Update: Opportunity Quietly Completes 9 Years Uncovering More Evidence of Water

A.J.S. Rayl • February 06, 2013

With its robot nose to the Martian grindstone, Opportunity completed its ninth year of working on Mars in January, making another significant science discovery in tiny white veins on Matijevic Hill as the Mars Exploration Rover (MER) mission rolled on into Year 10.

Columbia, ten years on

Remembering Rick Husband, William McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, and Ilan Ramon on the tenth anniversary of the loss of the space shuttle Columbia.

Field Report From Mars: Sol 3182-3188 - January 6-11, 2013

Larry Crumpler • January 11, 2013

We finished up with examination of the big outcrop ("Copper Cliff") and moved to the next target over the weekend. With that drive Opportunity completed the loop around Matijevic Hill and is now back where it started on the big loop to examine the outcrops.

Mars Exploration Rovers Update: Opportunity Zeroes In on Clay Minerals and We Look Back on 2012

A.J.S. Rayl • January 08, 2013

Despite the lull of the holidays, the Mars Exploration Rover (MER) mission recorded one of the expedition's best months ever in December as Opportunity and her team confirmed the location of the smectite clay minerals on Matijevic Hill, effectively grabbing the scientific brass ring they came hoping to find at Endeavour Crater.

Looking ahead to spacecraft activities in 2013

Emily Lakdawalla • January 04, 2013

2013 is going to be a busy year in space exploration. Two missions launch to the Moon (LADEE and Chang'E 3), and another two to Mars (MAVEN and India's mission). Curiosity should drive to the Mountain, and Opportunity to the next site on Endeavour's rim. Cassini will be seeing rings and Titan. Others should continue routine operations, except maybe MESSENGER, whose fate after March is not yet decided.

Planetary Society Weekly Hangout, Thu Jan 3 1200PT/2000UT: Jim Bell

Emily Lakdawalla • January 02, 2013

Join Emily Lakdawalla and Casey Dreier for a chat with Jim Bell, a scientist who wears many hats. He's the team lead for the Pancam color cameras on the Spirit and Opportunity rovers; he's a member of the Curiosity science team; and he's the esteemed President of the Planetary Society's Board of Directors. We'll talk about the great science being done by both Curiosity and Opportunity, and about what's in store for the future.

Field Report From Mars: Sol 3151-3153 - December 5-7, 2012

Larry Crumpler • December 07, 2012

An attempt to bump left and get a small bright vein into the instrument deployment device (IDD) work volume failed to get the target in the work plane.

Mars Exploration Rovers Update: Opportunity Digs In at Matijevic Hill

A.J.S. Rayl • December 03, 2012

While Curiosity and her team found themselves entangled in a media furor over comments, assumptions, and rumors of findings that have yet to be found, Opportunity roved on in November, finishing up the geologic survey of Matijevic Hill and setting a new mileage record along the way.

Field Report From Mars: Sol 3150 - December 3, 2012

Larry Crumpler • December 03, 2012

Here at station 14 we have decided to do a detailed investigation of an outcrop that is well exposed and lies within an area where there is orbital remote-sensing evidence for clay minerals. These particular rocks are interesting in that they contain a lot of thin veins and alteration zones along joints (cracks) in the outcrops.

Mars Exploration Rovers Update: Opportunity Begins Reconnaissance of Matijevic Hill

A.J.S. Rayl • November 06, 2012

After spending much of October driving around and taking pictures on Matijevic Hill, Opportunity hunkered down for Halloween and spent the holiday quietly, staying out of mischief's way and the Mars Exploration Rovers (MER) mission roved another month closer to its ninth anniversary of working on the surface of the Red Planet.

Field Report From Mars: Sol 3111- October 23, 2012

Larry Crumpler • October 23, 2012

We on the MER Opportunity science team are currently doing an “outcrop walk” with Opportunity on the slopes of Cape York, a small residual part of the rim on the 20+ km diameter Endeavour Crater, Mars.

Mars Exploration Rovers Update: Opportunity Finds Thrill of Newberries on Matijevic Hill

A.J.S. Rayl • October 03, 2012

On reconnaissance of Matijevic Hill, Opportunity has driven right into another Martian mystery, compete with new kinds of “berries," tiny white veins running through two distinctive outcrops of rock, and orbital data indicating that somewhere here clay minerals are hiding, all of which has put the Mars Exploration Rover (MER) mission back in the science spotlight and made for another September to remember at Meridiani Planum.

What's Up in the Solar System in October 2012

Emily Lakdawalla • September 28, 2012

Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.
