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.
Earlier this week, NASA announced that it was cutting off ties with Russia, except for activities relating to the ISS. This raised questions about Russian participation on NASA's science missions, particularly the Russian experiment on the Curiosity rover.

A Mars Reconnaissance Orbiter HiRISE image taken on February 10 shows Curiosity having just made deep, dark tracks across the Dingo Gap dune.
Some arm faults caused delays on Curiosity's approach to Kimberley, but the rover is now parked at its north edge, examining the "striated unit" up close with arm-mounted instruments.
Vignettes from dozens of LPSC talks: GRAIL and LADEE at the Moon; ice and craters and conglomerates and organics and gullies on Mars; polar deposits and volatile elements on Mercury; tectonics on Enceladus; and more, until my brain was so full I could barely speak.
With a series of drives over the last week, Curiosity is now approaching her next science stop at Kimberley. The distinctive knobs of the Kimberley outcrop are visible in photos taken on sol 569.

In a series of drives, Curiosity flew past the "striated terrain" that outcropped at Kylie, and is now negotiating her way around some rockier territory as she makes her way south toward the enticing outcrops of Kimberley.
The United States Geological Survey recently issued an improved version of the Viking color map of Mars. This 40-year-old data set still provides the prettiest global-scale map of the planet.

or “Pet Peeves and Deciphering Climate Change in the Solar System”
I have a pet peeve: the words dune and ripple are often used interchangeably, although they are quite distinct from one another. So what’s the difference between aeolian dunes and ripples? And why should anybody care?
