Planning for this past week has centered on analyzing the high potassium drill sample, Glen Etive 2, using the Sample Analysis at Mars (SAM) instrument. Portions of the drilled sample were delivered to SAM in Wednesday’s plan, and an evolved gas analysis (EGA) conducted. This involved heating the sample to very high temperatures and measuring the gases that bake out of the sample with each temperature increment. Following the successful completion of the EGA, SAM will uplink a sequence in today’s plan to clean the SAM Gas Chromatograph (GC) Columns, before some sample is transferred internally for a special wet chemistry experiment in next week’s plan. The Chemistry and Mineralogy (CheMin) instrument will also do some preparation work in this plan, ahead of a planned sample drop-off to CheMin at the end of next week.
Although we wanted to dedicate most of Curiosity’s resources to the continuing Glen Etive analysis, the Geology theme group (GEO) managed to fit in some geology observations. ChemCam will analyze two targets, investigating soil and pebbles at ‘Kilpatrick’ and refining bedrock composition at ‘Glen Lyon’ (previously shot on sol ...
