Stratigraphic columns are a basic tool in geology, used on both Earth and Mars to tell the story of a location. But what are they really?

The four-stop dune science campaign offered the engineers some time to continue troubleshooting the drill without any pressure to use it for science. They scooped sand at a site called Ogunquit Beach but couldn't complete the planned sample activity because of new developments in the drill inquiry. The rover has now headed onward toward Vera Rubin Ridge.

This week MAVEN had to execute a short rocket burn in order to prevent a future collision with Phobos. Curiosity (and other rovers) may have played a role in those trajectory predictions.

Since my last update, the Curiosity mission has developed a better understanding of the problem that prevented them from drilling at Precipice, but its intermittent nature has slowed the development of a workable solution that will allow them to use the drill again. In the meantime, the rover has driven onward, making good use of its other instruments.

It's been a drive-heavy two months for Curiosity. Since my last update, the rover has drilled at a site named Sebina, then traveled about 500 meters to the south across increasingly chunky-looking Murray rocks to a new attempted drill site at Precipice. They were planning to attempt a new drilling technique at Precipice, but encountered a new problem with the drill instead.

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.
