Sol 529 Update On Curiosity From USGS Scientist Ken Herkenhoff: The Scuff30 January 2014
At the end of the Sol 528 drive, the rover "scuffed" the dune with its right front wheel, then backed away and took images of the scuff. These images were used to confirm that the arm instruments can be placed in the scuff, to examine the freshly-exposed material within the dune. So no rover motion is required for contact science, and ChemCam and Mastcam observations of the scuff and vicinity were added to the Sol 529 plan. Another set of Mastcam and MAHLI images of the wheels are also planned, along with more reprocessing of CheMin data. After sunset, Mastcam will take a picture of Earth, currently an "evening star" in Mars' sky.
