Since I last checked in with Curiosity, the rover has been steadily driving southward, heading directly toward the Bagnold dune field. They are looking for a place to drill into the Stimson sandstone unit, but have been distracted by intriguing pale haloes around frock fractures. Despite a rough road, the wheels are not showing significant increase in damage.
How and why does Curiosity take self-portraits? A look at some of the people and stories behind Curiosity's "selfies" on the occasion of the official release of the sol 1065 belly pan self-portrait at Buckskin, below Marias Pass, Mars.

Since my last update, Curiosity has driven back and forth repeatedly across a section of rocks below Marias pass. The rover finally drilled at a spot named Buckskin on sol 1060, marking the drill's return to operations after suffering a short on sol 911. Now the rover is driving up into Marias Pass and onto the Washboard or Stimson unit.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
It’s been an eventful few weeks for Curiosity on Mars. From sols 981 to 986, Curiosity’s human pilots tried and failed to drive the rover southward; but, retracing their steps to Logan's Run, they quickly found a way up and into a beautiful geological amphitheater named Marias Pass, where they will stay throughout Mars solar conjunction. They also returned ChemCam to normal operations.
Curiosity is finally on the road again! And she's never taken a more scenic route than this. Her path to Mount Sharp is taking her to the west and south, across sandy swales between rocky rises.
Long before Curiosity's landing, the description of the color camera made me dream: I imagined what wonderful pictures we could get of sunsets and sunrises on Mars. They finally came on sol 956, the 15th of April, 2015.
Since I last wrote about Curiosity drilling at Pink Cliffs, the rover has visited and studied two major sites, drilling at one of them. It has also suffered a short in the drill percussion mechanism that presents serious enough risk to warrant a moratorium on drill use until engineers develop a plan to continue to operate it safely.
Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa 2, the Chang'e program, InSIGHT, and OSIRIS-REx.

Curiosity's second drilling campaign at the foot of Mount Sharp is complete. The rover spent about a month near Pink Cliffs, an area at the base of the Pahrump Hills outcrop, drilling and documenting a site named Mojave, where lighter-colored crystals were scattered through a very fine-grained rock.
A FOIA request offers insight into NASA's planetary science extended mission review process, which seems, at best, confusing, and at worst—with adjectival ratings like “Very Good/Good”—arbitrary.
Curiosity has spent the last two months completing a second circuit of the Pahrump Hills field site, gathering APXS and MAHLI data. The work has been hampered by the loss of the ChemCam focusing laser, but the team is developing a workaround. Over the holidays, the rover downlinked many Gigabits of image data. The rover is now preparing for a drilling campaign.
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.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
