Field Report From Mars: Sol 3378 - July 25, 2013

Larry Crumpler • July 26, 2013

We are now only about 180 meters from the new mountain, Solander Point. We slowed down this week so that we could check out the rocks here where there is a strange hydration signature from orbital remote sensing.

Field Report From Mars: Sol 3363 - July 10, 2013

Larry Crumpler • July 18, 2013

Opportunity is only a couple of hundred meters out and closing fast on the next mountain. A short side trip east is in the works to check out an anomaly in the terrain.

A new HiRISE view of Opportunity (sol 3361)

Emily Lakdawalla • July 17, 2013

The HiRISE camera on Mars Reconnaissance Orbiter has snapped a lovely color photo of the rim of Endeavour crater, catching Opportunity midway between Nobby's Head and Solander Point.

Programmable Mars Watch for $50

Ara Kourchians • July 11, 2013

Time is kept differently on Mars. This is because Mars itself rotates a little slower than Earth. This proves to be a pain when it comes to timekeeping.

Field Report From Mars: Sol 3355 - July 2, 2013

Larry Crumpler • July 08, 2013

By Sol 3325 Opportunity has driven up onto the next "island" of rock, "Sutherland Point" and "Nobbys Head." On this sol Opportunity is only about 700 m from the goal, the mountains to the south.

Mars Exploration Rovers Mission Update: Opportunity Continues Sprint to Solander Point

A.J.S. Rayl • July 04, 2013

The Mars Exploration Rover (MER) mission celebrated its 10th anniversary of leaving Earth in June, as Opportunity continued the sprint to its next winter haven at Endeavour Crater.

Is Opportunity near Lunokhod's distance record? Not as close as we used to think!

Emily Lakdawalla • June 21, 2013

A few weeks ago, a press release from the Opportunity mission celebrated Opportunity's surpassing of the previous NASA off-world driving record. That record was set in December 1972 by the Apollo 17 astronauts aboard their Lunar Roving Vehicle. They seem very close to Lunokhod 2's stated 37-kilometer driving record, but hold your horses -- we now know Lunokhod went longer than we thought.

Mars Exploration Rovers Update: Opportunity Departs Cape York, Breaks Apollo Record

A.J.S. Rayl • June 05, 2013

It was a merry and mighty month of May for the Mars Exploration Rover mission: Opportunity finished a blockbuster study of Matijevic Hill finding the best evidence yet for an ancient, potentially habitable environment, and then embarked on its first real road trip in two years. The robot field geologist had barely gotten underway on its journey when it surpassed the Apollo 17 lunar rover distance record to become the most traveled NASA vehicle on another planetary body.

Mars Exploration Rovers Special Update: Opportunity's Findings at Endeavour, So Far

A.J.S. Rayl • May 25, 2013

Mars Exploration Rover Opportunity left Cape York on May 14th and embarked on a 2-kilometer journey south along the western rim of Endeavour Crater. The rover is heading now to Solander Point, where it will spend the coming Martian winter.

Field Report From Mars: Sol 3317- May 24, 2013

Larry Crumpler • May 24, 2013

Opportunity finally started driving south from its location on the outcrop where it had been since solar conjunction.

Opportunity and Curiosity updates: Rolling and drilling and a little wear on the wheels

Emily Lakdawalla • May 20, 2013

For most of April, while Mars scuttled behind the Sun as seen from Earth, both Mars rovers were pretty inactive. Now that conjunction has ended, both are doing what rovers should be doing: roving and exploring. As of sol 3312 Opportunity had moved more than 300 meters southward toward Solander Point, while on her sol 279 Curiosity drilled at a second site, Cumberland.

Field Report From Mars: Sol 3310- May 17, 2013

Larry Crumpler • May 17, 2013

Opportunity has finally completed the detailed survey of the outcrops on the Cape York segment of the rim of the 22-km diameter Endeavour crater.

Planetary Society Hangout: A Day in the Life of the Opportunity Rover with Emily Dean

Casey Dreier • May 09, 2013

Thursday, May 9th, at noon PDT/3pm EDT/1900h UTC, we are joined by Emily Dean, who works on the camera team for the Opportunity rover on Mars.

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

A.J.S. Rayl • May 02, 2013

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

Bill Dunford • April 21, 2013

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

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

Larry Crumpler • March 01, 2013

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