As the leader of the Geology team, I was responsible for guiding our planned activities on Mars today. Our schedule included 1.5 hours of targeted remote science and contact science. We began by setting our sights on several targets for observations using ChemCam and Mastcam, including “Winnipeg,” “Alma,” and “Blackjack.”

Our first target, “Winnipeg,” located in the Murray formation, was assessed using MAHLI and APXS to determine its composition. Next, we turned our attention to “Alma,” which helped us characterize the composition across the Murray-Stimson contact. “Blackjack” presented a resistant ledge within the Murray formation that we also studied.

In addition to taking observations with ChemCam and Mastcam, we also planned to capture Mastcam mosaics to document the Murray-Stimson contact and study local structure and stratification. We also obtained a Mastcam tau to evaluate atmospheric opacity.

Afterward, in the afternoon, we acquired MAHLI images of the “Sacajawea” target to investigate another resistant ledge. Using the DRT, we brushed off dust from “Winnipeg” and took close MAHLI images to look for grain size variations. Finally, we used APXS overnight to analyze the composition of the “Winnipeg” target.
