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.
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 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.
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.
