Sols 4212-4214: Gearing up to Drill!

The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif. A black-and-white photo on the Martian surface is dominated in the lower half of the frame by a crosspiece of the Curiosity rover bearing its name, spelled in all-capitalized, white-outlined letters next to a white line drawing of the rover. The ground in front of it, visible from the middle to the upper part of the frame, appears as uneven, cracked slabs, with scattered small rocks beyond those.

Curiosity is gearing up to drill! Last week, it encountered a rock with unusual coloration and texture that was just out of reach (you can read about it and see pictures here and here). So that Curiosity could learn more about the geology around these rocks, it "bumped" – completing a 0.7-meter drive (2.3 feet) – to reach a nearby rock that’s big enough to drill! After many discussions over the past week with engineers, geologists, chemists, and more, the team has confirmed this target will be our next potential drill target (pictured). We’ve chosen the target name “Mammoth Lakes,” named for a town in California’s Sierra Nevada mountains with basalt columns, hot springs, and waterfalls.

Today, as the Keeper of the Plan for the Geology and Mineralogy theme group, I was busy recording all the necessary observations into the plan as we prepare to drill. In the first sol, we'll start with some essential preparatory activities. We'll use our Dust Removal Tool (DRT) to clean the surface, take detailed images with the Mars Hand Lens Imager (MAHLI) to capture the sedimentary textures, and analyze the composition with the Alpha Particle X-ray Spectrometer (APXS). These steps are crucial to understand the site's potential before we commit to drilling.

The second sol is where things heat up. ChemCam will fire up its Laser Induced Breakdown Spectroscopy (LIBS) to zap the rock and analyze its makeup. We then follow up this activity with imaging the surrounding area to help us understand the context of “Mammoth Lakes.” Mastcam will devote half an hour to capture a mammoth mosaic of the area, showing a potential contact in Gediz Vallis ridge which is marked by a transition from white stones into a coarser material. To top it off, we’ll use the ChemCam’s Remote Micro-Imager (RMI) to get some high-res shots of the sedimentary textures and structures within the surrounding rocks to help us understand the depositional environment when they formed.

Even with all these activities, the environmental science theme group managed to fit in some dust monitoring. Here's hoping all goes well, and we can make "Mammoth Lakes" our 41st drill hole!

A grayscale photograph of the Martian surface from the Curiosity rover captures medium gray, very uneven terrain in front of the rover, with many angular, lighter-toned, medium-sized rocks protruding from the smooth soil. The bottom of the frame shows part of the rover, running from the middle left to the lower right corner of the image, including part of its robotic arm which carries a nameplate imprinted with “Curiosity” outlined in all capital letters, and to the right of that a line drawing of the rover.

A grayscale photograph of the Martian surface shows, in the foreground, medium gray soil that looks like wind-blown sand dunes, with a few rounded, medium-sized rocks poking up from the ground. Beyond this area, and covering the upper half of the frame in this circular image, is much more rocky terrain, with both sharp and rounded rocks of all sizes covering the ground.

Sols 4368-4369: The Colors of Fall – and Mars

A grayscale landscape photo from Mars, showing a broad, medium gray, rock-strewn plain in the foreground extending far into the distance, surrounded by several hills. The closest hill, in the lower right corner, rises up toward the side of the frame, and is darker than the floor below. A little farther out, on the left, a gentle slope rises from the low middle of the frame to middle of the left side; it’s about the same color as the valley floor, except for a band at its farthest edge, which darkens abruptly as if covered in shadow. The terrain appears softer than the ground below, more sandy than rocky. Beyond that along the same rising plane is a much lighter area, with scattered tiny peaks that are darker – looking like the top of a baked meringue pie. The channel floor runs between these hills, then appears to curve toward the right, behind the first hill and in front of the second. Finally, one other rounded peak appears above the horizon, behind these other two hills in the lower right of the frame, all of this below a light-gray sky filling more than half of the frame above.
