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.
All seven Mars spacecraft are doing perfectly fine after comet Siding Spring's close encounter with Mars.
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.
The biggest news on Curiosity of late is that the rover has drilled her fourth full drill hole on Mars! Drilling happened at a site called "Confidence Hills" on sol 759. But before she did that, she took a long series of amazing photos of rock formations at Jubilee Pass, Panamint Butte, and Upheaval Dome.
A lot has happened behind the scenes on the Curiosity mission in the last few weeks. The mission received a pretty negative review from a panel convened to assess the relative quality of seven different proposed extended planetary science missions. Then, just a week later, the mission announced big news: they have arrived at Mount Sharp.
Curiosity Rover Science Plan Slammed by NASA Review Panel
Planetary science senior review still supports continued funding
Senior review recommends continuing all major planetary exploration missions, but not without some changes.
Shooting video of a lumpy moon crossing the Sun and turning it into a giant googly eye is not a new activity for Curiosity, but I get a fresh thrill each time I see one of these sequences downlinked from the rover.
The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.
Now that a Tiger Team has assessed the nature and causes of damage to Curiosity's wheels, I can finally answer your frequently-asked questions about what wheel damage means for the mission, and why it wasn't anticipated.

On Wednesday's "Virtually Speaking Science" podcast, The Planetary Society’s Emily Lakdawalla and Space.com contributor Rod Pyle look back at the first two years of the Curiosity Rover’s mission on Mars, and look ahead to the future of Mars exploration. NBC News science editor Alan Boyle is the host for the show, which airs at 5pm Pacific / midnight UTC.
For the last four weeks, the name of the game for Curiosity has been driving. But these weeks of driving have been more challenging than they used to be.
Just after completing the primary mission of 669 sols on Mars, Curiosity's managers planned a special day -- June 26, 2014 -- in which mostly women were assigned to the more than 100 different operational roles.
On Monday JPL put out a press release marking one year since Curiosity landed -- one Mars year, that is! There was a new version of the Kimberley self-portrait, and a video update on wheel wear testing. While we've been celebrating on Earth, Curiosity has been driving, driving, driving, on a new "safe transit route" taking her southward toward the black sand dunes ringing Mount Sharp.
I am both elated and relieved that Rob Manning and William Simon have written Mars Rover Curiosity: An Inside Account from Curiosity's Chief Engineer. The book delivers on the promise of its title, in a slender volume that is full of great stories you'll read nowhere else.

Curiosity has been busy. The rover has traveled more than half a kilometer since my last update, making steady progress beyond the Kimberley toward Murray Buttes. There hasn't been much time for science, but they sneaked in an observation of a Mercury transit across the sun, and a neat MARDI video of the rover driving.
