Our attempts to drill grey rock on the "Vera Rubin Ridge" (VRR) continue. We are returning to an area known as "Lake Orcadie," the site of two previous drill attempts (Lake Orcadie and Lake Orcadie 2), which did not penetrate far enough into the bedrock to generate sufficient sample. However, the MSL team feels that the chances of drilling here have improved. Over the past 240 sols, the engineers have further refined the drill technique (here), leading to two successful drilling campaigns (Duluth and Stoer). Additionally, images collected during our previous visit here have helped us to identify three potential drill targets. Criteria such as scratches left in the bedrock by the Dust Removal Tool (DRT) will be used to see if these targets are softer, and therefore more drillable, than our previous choices.
