Evaluating a Possible Drill Location

The weekend drive went well and Curiosity is back on top of the marker band, investigating some intriguing rippled bedrock. We’re assessing whether we want to drill at this location, based on what we see in the chemistry data.

So today’s two-sol plan is devoted to collecting data from APXS and MAHLI (supplemented by ChemCam and Mastcam), to evaluate the bedrock in our workspace, as seen in the above Navcam image. The target of interest is the bright rippled bedrock slab in between the shadow from the arm and the shadow from the mast in that image.

I was on shift as LTP today, and it was fun to think about the possibility of drilling here, and what our options would be if we decide not to pursue that. The team put together a lot of great activities to characterize this block and the surrounding area. First we’ll use the DRT to brush off a clean surface at a target named “Amapari.” Then APXS will do a short integration to provide data down in time for planning on Wednesday. ChemCam will assess the chemistry of the darker crest of a ripple at “Trovao” and Mastcam will collect a stereo mosaic over the workspace.

Mastcam will also document the morphology of some nearby ripples, and take a multispectral observation of the DRT target “Amapari.” Later in the afternoon, MAHLI will image “Amapari” and another ripple crest named “Orocaima.” Then APXS will acquire two longer nighttime integrations on those targets.

The second sol includes ChemCam LIBS on “Amapari” as well as a long distance RMI to assess an inverted channel. The plan also includes several environmental monitoring activities to search for dust devils and monitor the opacity of the atmosphere. Can’t wait to get the data down and hopefully plan our next drill!

Analyzing the rhythmically layered bedrock above the marker band: Sols 3669-3670

Pasadena CA (JPL) Dec 02, 2022

Curiosity drove ~25 meters back toward the Marker Band from our detour to the Gediz Vallis Ridge and has returned to the rhythmically layered bedrock we observed on Sols 3648-3649.

The first time Curiosity encountered these rocks we were unable to analyze them because one of the rover’s wheels was perched on a rock. Now that we are parked safely, we will use a “Touch and Go” approach where Curiosity will have a busy morning collecting images and data before driving ~15 meters to our next location. … read more
