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.

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.

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.

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.

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.

Ten years ago, Spirit launched on a Delta II rocket toward Mars, and I was there to see it.

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 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.

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

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.

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.

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

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

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.

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.

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.

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.

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.

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