Sol 5026, March 15, 2018. For the first time in more than a year, Opportunity’s mission team put the rover’s Rock Abrasion Tool (RAT) to work on a target: Aguas Calientes, part of the large Ysleta del Sur outcrop. The pre-brush view of Aguas Calientes is here, and above is the post-brush view; the area cleaned by the RAT is the partly circular dark region in the center.
Below is the view from Opportunity’s Navcam, looking downslope over the Ysleta del Sur outcrop. The tracks at left show where Opportunity drove over to examine Perseverance Valley’s North Wall and the Nueva Vizcaya target. Click either image to enlarge it.
