Even robots deserve a break once in a while, and when the Mars Odyssey orbiter went into safe mode in June, Opportunity got the chance to hang out and leisurely take in her surroundings at the Red Planet, while the Mars Exploration Rover (MER) mission downshifted into lower gear.

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.

Earlier today, unnoticed by the vast majority of the world, Opportunity reached and then silently passed a major milestone in her great adventure on Mars. At just before 3am, UK time, Opportunity began her 3000th sol, or martian day, on Mars.

When people first hear about how Curiosity will land on Mars, their first question always is: are they nuts? This is the second in a multi-part series describing how -- and why -- Curiosity will land this way, in excruciating detail.

Hundreds of images from the Mars Reconnaissance Orbiter’s HiRISE camera are publicly available, if you know where to look.

This Cosmoquest Science Hangout featured Ravi Prakash, Curiosity Entry, Descent, and Landing Systems Engineer. He explained how Curiosity will land on Mars, and why they've changed things since Spirit and Opportunity landed.

There was good news and bad news in this morning's press briefing about Curiosity rover's upcoming landing on Mars, just eight weeks from now. First, the good news: the landing ellipse has shrunk. The bad news: there's a contamination problem with the drill, and the Odyssey orbiter is in safe mode.

Glen Nagle pointed me to two awesome papercraft models of the Curiosity rover that you can download and -- assuming you have a LOT of patience and a steady hand -- assemble.

Mars rover driver Scott Maxwell relates a story of how he handed Ray Bradbury an opportunity to drive on Mars.

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.

May 16, 2012 is the third martian anniversary of the start of Mars Climate Sounder (MCS) observations from Mars Reconnaissance Orbiter. MCS started measuring the atmosphere of Mars three Mars years ago, on September 24, 2006. We can now compare the weather and behavior of the atmosphere in three different years, and find the temperature differences to be surprisingly large.

I took a field trip to watch scientists and engineers play in the sand with Mars rover models, and got a bonus tour of some evidence for the

After driving off Greeley Haven – where she stood patiently for 19 long weeks – Opportunity is now driving again. Not just turning, not just bumping, but driving.

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.
