Some of the Duluth drill sample was dropped into CheMin on Sol 2061, but not enough for a proper mineralogical analysis. So the top priority for today's plan is to again test the new drop-off procedure. Since the drill feed mechanism became unreliable over a year ago, drill samples can no longer be sieved and processed in CHIMRA, as they were earlier in the mission. Instead, portions of the sample must be dropped from the tip of the drill directly into the analytical instruments. This new Feed-Extended Sample Transfer (FEST) procedure will be repeated on Sol 2064, over bedrock and over the closed SAM inlet cover. Mastcam images will be taken both before and after the drop-off in both locations, to allow the size of the sample portion to be estimated. The results of these tests will be used to inform future drop-off planning.
