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.

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.

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.

The Mars Exploration Rovers' fourth Martian winter is proving to be the harshest one yet and Spirit and Opportunity are getting colder than ever before. With temperatures on the Red Planet dropping in April and the Martian winter solstice still two weeks away, the season has turned into a shivering nail-biter.

March seems to have come in like a lamb and gone out like a lion on the Red Planet this year as the Mars Exploration Rovers trudged deeper into their fourth winter. While Opportunity finished up work at Concepcin Crater and shifted into gear back on the road to Endeavour Crater, Spirit finished up winter preparations and carried out a limited winter agenda before shifting, it appears, into hibernation mode.

As winter put the freeze on in the southern hemisphere of the Red Planet, the Mars Exploration Rovers slowed down a bit, but continued throughout February to demonstrate the mettle that made them famous: Spirit successfully drove backwards, parked in place for the season, then continued working, as Opportunity roved through rock debris on a cruise around the rim of Concepcin Crater.

Five and a half years after they were supposed to be history, the Mars Exploration Rovers celebrated their sixth Earth year on the Red Planet with Opportunity pulling up to a fresh, new crater on the road to Endeavour, and Spirit working on repositioning itself to settle in for the coming Martian winter, and perhaps the rest of its mission.

Since leaving Marquette Island on sol 2,122, Opportunity has been barreling southward on her journey toward Endeavour crater. On her horizon for the last several sols has been a very small but very fresh looking crater named Concepción.

While we don't have Moon bases, we do have plenty of spacecraft. Before I get into my more detailed look at the activities of the 20-odd spacecraft wandering about the solar system, I thought I'd look ahead to 2010 more generally and see what the year has in store for us.

The Mars Exploration Rovers quietly wrapped up 2009 this month: Spirit continued to valiantly spin its wheels in an attempt to get out of its embedded location on the west side of Home Plate in Gusev Crater; and Opportunity continued its investigation of Marquette Island, perhaps the oldest Martian rock it's found to date at Meridiani Planum.

The Mars Exploration Rovers managed to make history and uncover history in November and that put both Spirit and Opportunity in the planetary exploration spotlight during the 71st month of an overland expedition that was supposed to be a three-month tour.

On Monday, November 16, 2009, Mars Exploration Rover Spirit will begin the much-anticipated, weeks-long process of extricating itself from a patch of powdery soil that stopped it in its tracks six months ago. It will begin by driving forward to the north, following its tracks out, even though its right front wheel is broken and immobilized.

The Mars Exploration Rover mission logged another textbook-rewriting month in October 2009 with more discoveries of geologic gems, new robot achievements balanced with equal amounts of challenges and frustrations overcome, topped off with special honors.

From notable achievements and new discoveries to trials and tribulations and harbingers of hope, the Mars Exploration Rovers seemed to experience the gamut on the Red Planet this September, their 69th month on an expedition that originally set out back in 2004 for a three-month tour.

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.

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.
