In the last few days, Opportunity's passed by several craters, and the rover drivers took advantage of the chance encounters for what they call

Just a linky post here.

For the Mars Exploration Rovers, October was a lot like September, which was a lot like August: Spirit continued hibernating at Gusev Crater or so it appears since the rover didn't phone home; and Opportunity picked up the pace to Endeavour Crater again, setting new driving records and marking more milestones along the way.

Waaaay back when Spirit and Opportunity landed on Mars in January 2004, the Planetary Society helped the public participate in the missions with a number of projects, including one where we printed

As Opportunity picked up the pace to Endeavour Crater this month and crossed the halfway point on the long journey from Victoria Crater and Spirit continued sleeping in hibernation mode, the Mars Exploration Rovers chalked up their 81st month of what was supposed to have been just a three-month tour of the Red Planet.

Opportunity is continuing to make tracks toward Endeavour crater, but just because she's got a goal for her road trip doesn't mean she won't stop and smell the flowers from time to time. Er, did I say

What a difference a couple of months of driving make. Here's the sort of view of the Mars Exploration Rover Opportunity's road ahead that I'm accustomed to, taken two months ago.

If I have to, I will drag reluctant people one at a time to plunge into NASA's Planetary Data System.

With the Sun beginning to warm the landscape in the southern hemisphere of the Red Planet and winds whipping up here and there forming dust devils that kick the powdery, rust-colored topsoil into the atmosphere, the Mars Exploration Rovers have been experiencing sure signs of a Martian spring this month.

I've had a fun morning of noodling around learning how to write KML files, and have produced one for Google Mars that shows you all of the Mars Orbiter Laser Altimeter tracks that cross the area Opportunity has driven through already, as well as the area of Endeavour crater.

Rover fans have been excitedly watching the hills on Opportunity's horizon grow taller and taller as Opportunity rolls toward its destination, Endeavour crater.

Winter lingers in the southern hemisphere of the Red Planet, but the Sun is beginning to rise higher in the sky and temperatures are slowly rising, signs the Mars Exploration Rovers are heading into spring. While Spirit continued hibernating, Opportunity took in the warmth of the Sun, captured its first dust devil, and picked up the pace in Meridiani Planum on the long journey to Endeavour Crater. Together, the rovers marked six and a half years of exploration.

With winter still freezing the southern hemisphere of Mars, June might have been an uneventful month for your average working robot, but not the Mars Exploration Rovers (MERs). In fact, from the sounds of silence to a major discovery to an injury scare, the rovers' latest trials, tribulations and achievements, have turned the last four weeks into something of an emotional roller-coaster for some members of the MER team.

Mars Exploration Rover Spirit continued to hibernate this month, parked in place near an old volcanic formation called Home Plate. At the same time though she managed to rove back into the planetary exploration spotlight when a group of the mission scientists announced they had found -- in data from an outcrop the rover visited more than four years ago -- evidence for a past watery environment more suitable for life than any other either Spirit or Opportunity have found, a place where near-pure water existed. 1

The Mars Exploration Rovers made it through their fourth winter solstice in what is the coldest, most challenging Martian winter the twin robot field geologists have experienced.

As I discussed on Monday, Opportunity is in the middle of a lengthy trek toward a crater named Endeavour and its tantalizing upraised smectite-bearing rim.

Opportunity's kilometers-long march across the sands of Meridiani Planum is a great story, and the journey is fun to follow; but what could be worth such a long march?

Today is sol 2,246 of Opportunity's mission to Mars; as I write, it's just before 7:00 local solar time. If this sol passes, as her previous 2,245 have done, with Opportunity still alive and speaking to Earth, she will have surpassed a record set on November 12, 1982: Opportunity will pass Viking Lander 1 as the longest-lived landed Mars mission.

Thumbing her nose at this whole winter thing, Opportunity drove 20 meters yesterday, sol 2,240, on the winter solstice.
