Curiosity update: A slight change of plans

FLB_618807208EDR_F0763002FHAZ00341M_-br2Sols 2495-96, August 12, 2019, update by MSL scientist Vivian Sun: Today’s planning began with a bit of a shuffle as we learned that the sample cup that was used for SAM preconditioning over the weekend didn’t seal as well as desired. This preconditioning step is required before we can perform SAM Evolved Gas Analysis (EGA) on the “Glen Etive” drill sample. In response, we elected to redo the SAM preconditioning activity using another cup, in addition to running another CheMin analysis. These changes freed up additional time for remote sensing observations in this 2 sol plan.

We planned a variety of ChemCam observations, including a retargeting of the Glen Etive drill hole in order to better adjust the focus parameters. We identified a rock called “Scone” with nicely exposed layers that we will sample with a vertical raster, and will also target another bedrock target called “Crannog.” There was also time to take a long distance RMI mosaic of the sulfate unit to image sedimentary structures… [More at link]
