Our campaign to analyze “Namib Dune” continues! In the sol 1230-1231 plan the main event is dropping off some sand in the SAM instrument, but some of the other instruments got a workout too. The sol 1230 plan originally included a science block with some ChemCam, Mastcam, and Navcam observations, but unfortunately that had to be cut to save power, so those observations will have to happen over the weekend. With the science block removed, the first activity on sol 1230 is a Mastcam observation of the SAM inlet. After this, the rover will drop off a sample of sand for SAM to analyze. Then while the arm is active MAHLI will observe the dump piles, including some night-time observations using the built-in LEDs to illuminate the piles.  APXS also has a couple of overnight measurements on two of the dump piles.

On Sol 1231, we will start off with some Navcam and Hazcam images to document where APXS was making its measurements, plus Mastcam observations of the SAM inlet again. This will be followed by some arm activities to clean out the components of the sample handling system. Then we’ll dive back in and collect another scoop of material from the dune, sieve it, and deliver it to SAM too. Finally, APXS will be placed on another of our dump piles for an overnight measurement. And of course REMS and DAN will be collecting data each sol of the plan as usual.
