We are continuing the sequence of drill activities at Aberlady. We will be collecting APXS of the dump pile with two offset observations to better understand any compositional variations, which are hinted at by the color variations observed in the drill fines (see above image). We will also be performing another CheMin integration to further refine the mineralogic analyses for Aberlady. We will also take MAHLI images of the dump pile and the drill hole. Discussions of whether we should drill again near our current workspace or drive away and drill elsewhere are still ongoing, but to cover our bases we planned an APXS and MAHLI observation of ‘Seil’ for reconnaissance on potentially drillable bedrock.
Many of our remote sensing activities were designed to characterize the compositional variability of the bedrock in this region. We planned a series of ChemCam LIBS rasters on ‘Glen Water,’ ‘Ben Vane,’ ‘John O Groats,’ and ‘Kirkcaldy,’ as well as their corresponding Mastcam documentation images. We also planned a ChemCam target on a possible meteorite fragment called ‘Lumphanan.’ This observation is unusual because ChemCam targets are usually limited to within approximately 7 meters distance of the rover mast, as data quality decreases at longer distances. ...
