While investigation of the drill anomaly continues, more diagnostic tests will be performed on Sol 1542.  Again, no mobility or other arm activities will be planned, so the science team added only remote sensing observations.  ChemCam will observe Hunters Beach again to further investigate the the chemical variations that LIBS measured there previously.  ChemCam and the Right Mastcam will also observe bedrock targets "Sargent Mountain" and "Youngs Mountain."  Finally, Navcam and Mastcam will take one more set of images at 8 AM on Sol 1543, to complete the photometry dataset started on Sol 1537.
