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.
The last couple of weeks have seen Curiosity return to the business of making steady headway toward Murray Buttes and, beyond them, Mount Sharp. Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.
Mars Express and Mars Reconnaissance Orbiter are keeping their eyes in the sky on Curiosity. There's a nice newly public color image of all of Gale Crater from HiRISE, and two new HiRISE images within the Curiosity landing site.
Curiosity and Opportunity self-portraits show one rover accumulating dust, the other losing it. Check out these cool before-and-after comparisons.
Finally, a new drill site! For the first time in nearly a year, Curiosity has put drill bit to rock and acquired a new sample of Martian material for her analytical instruments to chew on. Scientific data collection at Windjana is now complete; Curiosity drove away last night, on sol 630.
Curiosity took a new self-portrait on sol 613. This post contains a tip for would-be Curiosity image processors on how to make their Curiosity mosaics better: removing the smearing effect of bright objects in MAHLI photos.
After completing the initial reconnaissance of the Kimberley outcrop two weeks ago, Curiosity is, at last, moving toward a drill site. The science team selected the location last week: a spot near the base of Mount Remarkable, into what they have been calling the "middle unit" at the Kimberley.
Imagine yourself on a windswept landscape of rocks and red dust with mountains all around you. The temperature -- never warm on this planet -- suddenly plunges, as the small Sun sets behind the western range of mountains.
Curiosity has been busy performing a survey of the Kimberley, walking the length of the outcrop and taking enormous quantities of photos. The team is now ready to go in for a closer look, and maybe even to drill.
