MER Updates for 2010

Mars Exploration Rover Update: Spirit Silent Still, Opportunity Savors Santa Maria, We Flashback on 2010

Posted 2010/12/31 11:00 CST

The Mars Exploration Rovers are wrapping up another year of exploring their seventh -- having experienced both the best of times and the worst of times: Spirit continued a 10-month struggle to endure its coldest, harshest Martian winter yet; Opportunity set a new record for driving despite an arthritic front wheel and a broken shoulder, putting more miles on her rocker bogie in 2010 than in any other single year.

Mars Exploration Rovers Update: Mission Looks Back in Honor to Apollo 12, and Drives Exploration Onward

Posted 2010/11/30 11:00 CST

The Mars Exploration Rovers (MER) forged on in November, their 83rd month of an expedition originally planned for three months: Spirit remained silent at Gusev Crater presumably still re-charging her batteries, as Opportunity roved through a field of craters pressing on toward Endeavour Crater, quietly claiming title along the way to being the first roving robot to drive 25 kilometers on Mars.

Mars Exploration Rovers Update: Spirit Remains Silent, Opportunity Pushes on to Endeavour

Posted 2010/10/31 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Snoozes through September , Opportunity Bolts Past Halfway Mark to Endeavour Crater

Posted 2010/09/30 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Hibernates Still, Opportunity Pulls into Cambridge Bay

Posted 2010/08/31 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Sleeps Soundlessly, Opportunity Turns a Corner

Posted 2010/07/31 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Rests on Big Find, Opportunity Finishes Half-Marathon on Way to Endeavour

Posted 2010/06/30 12:00 CDT

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 Rovers Update: Spirit Team Announces Major Water Discovery

Posted 2010/06/17 12:00 CDT

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

Mars Exploration Rovers Update: Spirit Sleeps through Solstice, Opportunity Cruises Past Viking Record

Posted 2010/05/31 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Snoozes Past Viking, Opportunity Snaps Endeavour on Horizon

Posted 2010/04/30 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Begins Hibernation Probably, Opportunity Roves On to Endeavour Crater

Posted 2010/03/31 12:00 CDT

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.

Mars Exploration Rovers Update: Spirit Parks for Winter, Opportunity Tastes Chocolate Hills

Posted 2010/02/28 11:00 CST

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.

Mars Exploration Rovers Update: Rovers Pass 6-Year Milestone as Spirit Halts Extrication to Winter at Troy, Opportunity Cruises to Concepcion Crater

Posted 2010/01/31 11:00 CST

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.
