Doug Ellison has done it again: he's created a spectacular overflight of Gusev crater based upon digital elevation models of the terrain produced by the United States Geological Survey from HiRISE data.

For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.
The Mars Exploration Rovers hunkered down in place in August and delivered more mission "gold" as they achieved new milestones and uncovered more scientific gems, not the least of which was a blockbuster of a meteorite. But August proved to be a stormy month, uniquely challenging and one that many on the Mars Exploration Team will never forget.

"Third anniversary?" some of you may be asking. "Hasn't it been more like five years since Spirit landed?" Five Earth years, yes. But today is the third anniversary of the landing, measured in Mars years.

While Spirit has been stuck at Troy, it's been taking numerous opportunities to capture photos with dramatic twilight lighting. On sol 2,002 (three sols ago, or August 21), it gazed toward the setting Sun, snapping the shutter roughly once a minute.

Today the HiRISE team released a lovely new view of Victoria crater, taken nearly a year after the Opportunity rover departed it.

The Mars Exploration Rovers maintained a busy schedule in July: Spirit worked day and night doing whatever it could to make use of its abundant energy; Opportunity effectively treated its “hot” right front wheel and got back to making some consecutive long drives toward the still distant Endeavour Crater.

It's been a relatively quiet but scientifically significant month on the Red Planet for the Mars Exploration Rovers. While Opportunity continued its long journey to Endeavour Crater, forced to take it slower and make longer stops to rest its 'hot' front wheel, Spirit, seemingly just biding its time embedded in a sand pit it slipped into in April, turned up one of the most intriguing discoveries on the mission to date.

The Mars Exploration Rovers hit some rough patches in May as Spirit sat stuck in a sand patch all month and Opportunity had to stop again to rest its right front wheel but with a little help from Mars, the intrepid, twin robot field geologists cruised through the summer solstice with the energy and invincibility of a couple of teenage robots.

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

The Mars Exploration Rovers challenged their ground crews with an April full of high drama, a little suspense, and a lot of energy. While Spirit lived through a kind of robot soap opera, complete with bewildering reboots and bouts of amnesia, Opportunity roved forward and back into the fast lane on a restored front wheel, slowing down for a brief visit to a series of small, intriguing craters and an unplanned close encounter with a pesky little purgatoid.

The Mars Exploration Rovers logged a memorable March, with Spirit finally making some serious tracks and setting a new driving record for a five-wheeled rover, and Opportunity getting a first glimpse on the distant horizon of its next big attraction, Endeavour Crater as it crossed a geologic boundary into a new field of "blueberries."

Way to go, Spirit! The last two drives for the five-wheeled rover have taken it a total of about 40 meters west, traveling around the north edge of Home Plate. If I'm not mistaken, that's more than Spirit has driven in the last 400 sols combined.
