There have been tons and tons of HiRISE images of the Curiosity landing region, and it has taken quite a lot of work for me to find, locate, and catalogue them. This post is a summary of what I've found; after four revisions and updates, it's now version 2.0 of the list.

At the American Geophysical Union meeting, the Curiosity mission announced that an instrument had finally definitively detected methane in Mars' atmosphere. It exists at a low background level, but there was a spike to about ten times that, which lasted for a couple of months before disappearing. What that means is unclear.

Opportunity is continuing its drives along the rim of Endeavour toward Marathon Valley. Larry Crumpler tells us what to expect as the rover continues its journey.

With the announcement of Curiosity's detection of methane on Mars, Nicholas Heavens gives us a guide to the history of methane detection on Mars, a discussion of its scientific significance, and a few things to consider when hearing about and asking about the detection.

The Mars Reconnaissance Orbiter just keeps delivering remarkable scenes from the Red Planet.

Last month, the Earth's longest-lived and most traveled robot on another planet drove into a network of fractures the likes of which the scientists had never seen before on Mars and wound up working there through the end of the month – and then something not completely unexpected happened.

At Pahrump Hills, Curiosity is becoming the field geologist she was intended to be.

As winds whirled and converged to the west of Endeavour Crater, Opportunity's power dropped dramatically in October, but the Mars Exploration Rover (MER) pressed on. By month's end, the robot field geologist had completed her assignments – including capturing the first close-in shot of a comet from the surface of the Red Planet – and was roving onward through the darkness, driving the mission into the 130th month of what started out more than 10-and-a-half years ago to be a 3-month tour.

It's been two weeks since comet Siding Spring passed close by Mars, and six of the seven Mars spacecraft have now checked in with quick looks at their images of the encounter. I round up all the results.

At the Geological Society of America conference this week, Curiosity scientists dug into the geology of Gale crater and shared puzzling results about the nature of the rocks that the rover has found there.

The nucleus of comet Siding Spring passes close by Mars on Sunday, October 19, at 18:27 UTC. Here are links to webcasts and websites that should have updates throughout the encounter.

Curiosity spent a total of four weeks at Confidence Hills, feeding samples to SAM and CheMin several times. On two weekends during this period, the rover's activities were interrupted by faults with the robotic arm. Curiosity drove away from Confidence Hills on sol 780, and is ready to observe comet Siding Spring over the weekend.

Opportunity will become a comet flyby mission beginning in mid-October. The comet Siding Spring will zoom past Mars at a distance of about 135,000 km on October 19.

Today the Mars Orbiter Mission released a nice four-image animation of teeny dark Phobos crossing Mars' huge orange disk. Mars Orbiter Mission joins a long line of Mars missions that have produced images of Mars and Phobos together.

With only 10 days remaining until the arrival of Comet Siding Spring at Mars, ISRO has shielded the Mars Orbiter Mission (MOM) from the comet. On Tuesday MOM’s orbit was altered so as to move it behind the Red Planet when the comet arrives. MOM will carry out observations of the comet and its Mars Colour Camera will click images of it.

ISRO has released a second global image of Mars from the Mars Colour Camera on Mars Orbiter Mission, and smack dab in the center of it is Gale crater, home to Curiosity.

We're now less than two weeks away from Comet Siding Spring buzzing ridiculously close to Mars, and the excitement is building - in both good and bad ways...
