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

A.J.S. Rayl • December 31, 2010

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.

Opportunity drives within 20 meters of Santa Maria, spots alligator's tail

Emily Lakdawalla • December 15, 2010

Today Opportunity has driven to within 20 meters of Santa Maria crater, and the blocks around it are really, really cool-looking. This one is a dead ringer for the severed tail of an alligator.

Opportunity: "So close we can taste it" to Santa Maria

Opportunity is on a kilometers-long eastward road trip across Meridiani Planum toward the rim of a large ancient crater named Endeavour; it'll be many months yet before she gets there.

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

A.J.S. Rayl • November 30, 2010

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.

Opportunity bags a few craters

Emily Lakdawalla • November 10, 2010

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 "drive-by shooting" (a phrase I can't say I'm particularly fond of, but they didn't ask me).

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

A.J.S. Rayl • October 31, 2010

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.

Crack the code for a message from Mars, redux

Emily Lakdawalla • October 14, 2010

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 "secret codes" around the edges of the two names-bearing DVDs that were bolted to the Mars Exploration Rover landers.

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

A.J.S. Rayl • September 30, 2010

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 rolls up to Oileán Ruaidh

Emily Lakdawalla • September 22, 2010

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 "flowers?" I meant "meteorites."
