Sols 1151-1152: Rocky Roads in the Margin Unit – NASA Science

On Wednesday, we took advantage of being parked during a routine flight software update to take a closer look at the local rocks with our proximity science instruments. While there was limited outcrop in the vicinity of the rover, the team surveyed some options within reach and selected to abrade a target named “Old Faithful Geyser.” Such abrasion will allow us to look at a fresh and clean rock surface unobscured by dust or rock coatings. Since our last abrasion at the Bunsen Peak workspace almost 1 km to the east, the team has been working hard to understand the potential textural and compositional variability across the margin unit that may give important insight into the geologic history of these rocks. Following abrasion, the team will plan detailed chemical measurements with the PlXL instrument over the weekend.
