In the two months since my last Curiosity update, the rover has traversed the scenic Murray Buttes, drilled at Quela, and driven another 300 meters southward.
Whenever I share images from Curiosity, among the most common questions I’m asked is “what is the scale of this image?” With help from imaging enthusiast Seán Doran, I can answer that question for some of the Murray buttes.
Curiosity has now covered most of the flat ground that lay between the Naukluft plateau and the Murray buttes. The mission took only 11 days to complete drilling work at Marimba, despite a recurrence of a problematic short in the drill. The rover is ready to drive in among the buttes, shooting spectacular photos along the way.
Highlights this month include the impending arrival of Juno at Jupiter, the approval of extended missions for all of NASA's solar system spacecraft, and public data releases from Rosetta, New Horizons, and Cassini.
Curiosity is at a turning point in its mission to Mount Sharp, both literally and figuratively. Having drilled at three sample sites in 7 weeks, the rover took a left turn, changing its trajectory from a generally westward driving path to a southward one. It is now poised to cross the Bagnold dune field at Murray buttes.
Curiosity has drilled into Mars for the 10th time at a site named Lubango, on sol 1320 (April 23, 2016). Lubango is in a bright-toned halo around a crack in the Stimson sandstone unit on the western edge of the Naukluft Plateau.
Curiosity has driven onward from Namib dune across a highstanding unit of rock called the Naukluft Plateau. Despite some frustrating sols lost to a short circuit in the RTG and DSN troubles, the rover has made progress, and performed lots of 3D imaging of weirdly wind-eroded rocks.
Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.
Emily is back to work on her Mars Science Laboratory book, which has a new publication date and a new title.

Recently, space image processing enthusiast Thomas Appéré noticed that Curiosity had taken five photos of exactly the same spot on the rim of Gale crater, identical but for being taken at different times of day. That spot was due north of the rover, so the rising and lowering Sun illuminates the rounded hummocks of the crater rim differently from early morning to early afternoon.
Curiosity has spent the last month sampling and processing dark sand scooped from the side of Namib Dune. The rover has now departed Namib and is preparing to cross the Bagnold dune field, while working to diagnose an anomaly with the CHIMRA sample handling mechanism.
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 five revisions and updates, it's now version 3.0 of the list.
In the six weeks since my last detailed Curiosity update, the rover has driven to, on, and around a couple of active barchan sand dunes on Mars. They are now searching for a site to scoop and sample sand on the western edge of Namib dune.
In a remarkable and wholly unexpected gift to Curiosity fans, the rover has just taken the first-ever color Mastcam self-portrait from Mars.
Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
Since my last update, Curiosity drilled two new holes, at Big Sky and Greenhorn, and is now approaching Bagnold Dunes.
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.
