Since you last visited, Opportunity has continued to drive downhill – well, what passes for ‘downhill’ on Cape York! – and is now not far at all from the northern edge of the Cape. From where she is now she sees the Meridiani desert stretching away to the north and west, the eastern hills on her right, and the Cape itself behind her. And around her? lots and lots of Homestake-like gypsum veins.

The Mars Exploration Rover Opportunity strolled out of her winter haven this May to continue the expedition around Endeavour Crater, roving into yet another Martian spring.

As winter began to retreat in the southern hemisphere of the Red Planet, Opportunity was commanded to finish up her science assignments in April in preparation for leaving its refuge, and the Mars Exploration Rover mission rolled through its 100th month of exploration.
A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.

March came in like a lion and went out like a lamb at Meridiani Planum, Mars: Opportunity felt the cold wind on her solar panels, then "settled" in a little more, working through the depths of its fifth Martian winter, as the team honored one of its own up there, and the Mars Exploration Rover mission logged month number 99 of exploration.

There's no hail or snow or sleet, though it is the depth of winter at Meridiani Planum and a cold unimaginable to us has gripped the landscape.

It took Don Davis many hours of meticulous labor to assemble this beautiful postcard from Mars.

As Opportunity worked away on its winter science campaign, the Mars Exploration Rover mission quietly completed its eighth Earth year of exploring the surface of the Red Planet last week, and is now roving on into Year 9 of its 90-day mission.

Today Opportunity sent back to Earth the last few frames of the "deck pan" self-portrait she took during the waning days of 2011. Her solar panels are very dusty, which isn't helpful. It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.

As New Year's Eve moved from time zone to time zone across planet Earth, the Mars Exploration Rover (MER) team looked to 2012 and wrapping its eighth Earth year of exploring, while up on the Red Planet Opportunity settled into the "saddle" at Greeley Haven preparing for the onslaught of its fifth Martian winter.

Mars Exploration Rover Opportunity has discovered gypsum and its "single most powerful piece of evidence for liquid water on Mars."

Opportunity roved toward the end of its eighth year of exploration on the Red Planet and chalking up yet another "exciting" textbook discovery for the Mars mission.

As I was beginning my research for my two magazine articles on the Curiosity rover's upcoming mission to Mars, I needed to figure out for myself how exactly this gigantic, ungainly machine fit in to the context of past Martian missions.

Opportunity roved on this month, driving alongside the rim of Endeavour Crater toward the northern end of Cape York in search of more science gold and a place to hunker down for winter.

Since leaving the plains of Meridiani, pulling up to Endeavour Crater and checking out its first rock last month, Mars Exploration Rover Opportunity has wasted no time in getting the "new mission" underway.

In a now-routine act of obtaining detailed photographs of robots from Earth sitting on the surface of another planet, the HiRISE camera on Mars Reconnaissance Orbiter has captured a view of Opportunity sitting on the rim of Endeavour crater.
