As Curiosity arrived at her new bedrock-rich workspace after a weekend drive of ~18 m, the science team had to decide whether to quickly interrogate a contact science target with MAHLI and APXS using a touch and go, or stay and find out what lay beneath the dust. There were hints around the workspace that color variations were present, with surfaces visible in shades of tan, gray and purple, so the science team decided to push the drive off a day and stay to use the Dust Removal Tool (DRT) once again on the VRR rocks in the workspace.
The science team was not only in a cleaning mood, they were in a tongue twisting mood, as evidenced by the names of the two MAHLI and APXS targets, “Passadumkeag” (a small Maine town) and “Pennessewassee” (a lake near Norway, Maine). Passadumkeag, a tan-colored target, will benefit from the DRT’s revelatory powers, while Pennessewassee, a more gray-colored target, will be interrogated as… [More at link]
