Sol 1327, April 30, 2016. At Lubango, the CHIMRA sample handling device dropped the sieved (fine) portion of the drill tailings on the ground for the APXS to analyze (upper left).
To the upper right of the white debris next to the drill hole, an earlier dump pile contains contains gray drill tailings. The quantity was in excess of what was needed, so these tailings were dumped without being sieved. ChemCam will do shots on both piles to look for variations in composition due to particle size.
