Sols 4207-4208: A Taste of Rocky Road

Earth planning date: Wednesday June 5, 2024

Curiosity was still at the ice cream shop for planning today, with the delicious feast of rock flavours still at arm's reach and begging to be sampled. In the previous plan, one such flavour, captured in today's blog image and perhaps most analogous to Rocky Road (not only given that Curiosity drove over this rock causing it to fracture, but also arguably the appearance as well), caught the eye of the operations team. There was desire to place APXS on this target, "Convict Lake," in the previous plan but the team ultimately did not have the image data available that would permit Curiosity to safely do so at a suitably close distance for APXS. Not to be discouraged, Monday's operations team pivoted and utilized part of the plan to acquire images of Convict Lake that would enable better APXS placement in today's plan.

The required images for targeting Convict Lake (aka Rocky Road, just with a chocolate to marshmallow ratio that would leave chocolate lovers heartbroken) with APXS arrived just in time for planning today. These images made it possible to focus on the central task of today's two-sol plan: place APXS close to Rocky Road and target two areas that are specifically more "marshmallow" and less on "chocolate" (sorry chocolate fans).

In addition to APXS on Convict Lake, ChemCam also targeted Convict Lake using its laser and imaging capabilities.  MAHLI returned for seconds (and thirds!), only this time pairing yet more daytime images with others taken at night while utilizing its illumination capabilities. ChemCam and Mastcam also imaged "Petes Col" and "Buckeye Ridge," with Mastcam additionally imaging "Camp Four," as well as "Ten Lakes" and "Walker Lake" a number of times over the course of the two-sol plan.

I for one am very excited about the particular offerings at his specific shop and what we may ultimately learn from our sampling. I, like APXS, may just have two scoops of ice cream tonight myself, perhaps even following in MAHLI's footsteps by doing so after the sun has set when nobody else is watching (we've all done it, let's be honest). Unfortunately, I do not have Rocky Road, and I think I missed my chance to have watermelon (don't knock it until you try it!).

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

Article19 hours ago
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.

A close-up color photo from the Martian surface shows a pale orange rocky outcropping, which looks on top like a sheet of coarse sandpaper, and on the side facing the camera like the feature is made from numerous, stacked thin layers, with undulating edges that make it look like a topographic map. Atop the feature are multiple plates of smooth stone in the same pale orange color, in different shapes, at different angles to each other, with a texture resembling clippings of thick, dense felt.
