Curiosity takes selfie next to two of its most important drill holes
Click for full image.
The Curiosity science team today released a beautiful mosaic of the rover, stitched from 57 different images. The photo at the right, cropped and reduced to post here, is the annotated version of that image. It shows the rover’s two most recent drill holes to the left. As the view looks away from Mount Sharp, you can see in the distance Vera Rubin Ridge, the floor of the crater, and its rim on the far horizon.
The two drill holes are significant because of the chemical experiment that Curiosity is subjecting the material from those holes.
The special chemistry experiment occurred on Sept. 24, 2019, after the rover placed the powderized sample from Glen Etive 2 into SAM. The portable lab contains 74 small cups used for testing samples. Most of the cups function as miniature ovens that heat the samples; SAM then “sniffs” the gases that bake off, looking for chemicals that hold clues about the Martian environment billions of years ago, when the planet was friendlier to microbial life.
But nine of SAM’s 74 cups are filled with solvents the rover can use for special “wet chemistry” experiments. These chemicals make it easier for SAM to detect certain carbon-based molecules important to the formation of life, called organic compounds.
Because there’s a limited number of wet-chemistry cups, the science team has been saving them for just the right conditions. In fact, the experiment at Glen Etive is only the second time Curiosity has performed wet chemistry since touching down on Mars in August 2012.
This time however was the first time they had used a wet chemistry cup on material from a drill hole. That they were able to do this at all is a testament to the brilliant innovative skills of the rover’s engineers. They had been holding off doing a wet chemistry analysis from drill hole material until they got to this point, but on the way the rover’s drill feed mechanism failed. It took more than a year of tests and experimentation before they figured out a way to bypass the feed mechanism by using the arm itself to push the drill bit into the ground. That rescue made possible the wet chemistry experiment that they initiated on September 24.
The results, which are eagerly awaited, won’t be available until next year, as it will take time for the scientists to analyze and publish their results.
Curiosity meanwhile has moved on, leaving this location where it had remained for several months to march in the past week southward back towards its long planned route up Mount Sharp.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

A very cool picture, but I am a little stumped, as to how this photo was taken. I know it wasn’t Matt Damon or a friendly Martian taking it. But seriously, there is no arm holding the camera pointed back at the rover in the photo. It says the photo was many pictures stitched together but there is nothing holding the camera in the picture, was the robotic arm holding it simply photo shopped out of the picture. Puzzling?
Brian,
Take your phone. Keep your right arm at your side. Now extend your left arm in front of you and take a full-body selfie (assume you have a wide-enough-angle lens).
Next, keep your left arm at your side, extend your right arm in front of you and take another full-body selfie.
Take both images into Photoshop and use half of each one and stitch them together. Presto! A selfie of you with no arms holding the camera.
The tires look punctured.
Duane Ohling: The tires are punctured. See this earlier post from July 9, 2019. It also includes links to my previous posts on the state of Curiosity’s wheels.
Andi,
Ah so photo shop was involved, I was kinda right, figured there was some kind of trickeration going on.
