On Sol 1614, ChemCam and Right Mastcam will observe bedrock targets named “Columbia Falls,” “Spider Lake,” and “Loon Stream.”  Mastcam will measure dust in the atmosphere and acquire a 3×3 mosaic of a layered block dubbed “Aroostook River.”  Late that afternoon, MAHLI will image the REMS UV sensor and acquire mosaics of another bedrock target named “Chain Lakes” and of Spider Lake.  The APXS will then measure the chemistry of the Spider Lake area at overlapping locations to look for spatial variations in composition. Early the next morning, Mastcam will again measure dust in the atmosphere and Navcam will search for clouds. Later on Sol 1615, more drill diagnostic tests are planned, then the APXS will be placed on its calibration target for an overnight integration. A short drive to the dark dunes south of the rover is planned on Sol 1616, followed by unstowing the arm and post-drive imaging. Another busy (sometimes hectic) day for me as SOWG Chair!
