Today, I led the Geology team as we carried out our planned activities on Mars. Our schedule for the day included 1.5 hours of targeted remote science, followed by contact science. We set 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 used “Alma” to help us characterize the composition across the Murray-Stimson contact. The resistant ledge within the Murray formation presented by “Blackjack” was also studied.
In addition to these activities, we planned to capture Mastcam mosaics to document the Murray-Stimson contact and study the local structure and stratification. We also obtained a Mastcam tau to evaluate atmospheric opacity. 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 analyzed the composition of the “Winnipeg” target overnight using APXS.
