July 8, 2022 Update for Curiosity Rover: Sols 3528-3529: Everyone Gets to Savor the Avanavero Flavors!

Both the CheMin and SAM instruments have dined on the Avanavero drill samples and have decided their appetites are sated. CheMin has completed X-ray diffraction mineralogical analysis of the Avanavero drill sample, and SAM their Evolved Gas Analysis. Both instrument teams are satisfied with their analyses and SAM are not opting to do a Gas Chromatography-Mass Spectrometry run. Now it is the turn of MAHLI, APXS and ChemCam to investigate the flavour of the drill fines around the Avanavero drill hole for texture and chemistry, finishing up observations at this site before we drive away next week. The composition of the drill fines determined by APXS and ChemCam will help the CheMin and SAM teams refine interpretations of their data. The science team are all eagerly awaiting their results as we drive through this interesting transition from clay-bearing to sulfate-bearing strata.

Perseverance Rover July 7, 2022 Update: Searching for Sand Transport

"Perseverance is currently stopped for sampling at Skinner Ridge rock. Sampling activities constitute an important aspect of Perseverance’s mission, and the rover’s strategic path is developed around sampling stops. During these stops, the rover must remain stationary for at least twelve sols in order to conduct proximity science and activities related to abrasion and coring. But being parked in one location for this extended period of time is also useful for something else. "

"Sampling stops provide rare opportunities to conduct “change detection” experiments, which are used to monitor wind-driven — or aeolian — transport of sand. The basic concept behind change detection is simple: compare identical images of the surface acquired at different times to search for wind-induced movement of sand. These observations can be used to deduce information about the relative strength and direction of winds blowing in the time between the two images. Sand deposits and aeolian bedforms (such as the sand ripples seen in the accompanying Mastcam-Z image) are ideal targets for change detection."
