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."

Opportunity's rocky road ahead, good news for an aging rover

Emily Lakdawalla • September 15, 2010

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.

Getting to the real science image data: It's not that hard!

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

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

A.J.S. Rayl • August 31, 2010

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.

Bringing MOLA altimetry tracks into Google Mars

Emily Lakdawalla • August 27, 2010

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.

A first look at distant hills

Emily Lakdawalla • August 25, 2010

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

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

A.J.S. Rayl • July 31, 2010

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.

JPL begins actively hailing Spirit -- but is trying to manage your expectations (an editorial)

Emily Lakdawalla • July 30, 2010

Spirit hasn't talked to Earth since March 22 -- so what new information could they have received that would make them pronounce Spirit's possible death? Is there some new analysis of the last bit of telemetry? Some new model indicating Spirit's survival was less likely than previously thought?

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

A.J.S. Rayl • June 30, 2010

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

A.J.S. Rayl • June 17, 2010

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
