NASA’s Curiosity rover resumed its examination of the Monte Grande hole on Sols 4743-4749, investigating polygon-covered bedrock till the outcrop was out of sight. The drive from the Nevado Sajama drill website enabled new imaging of the hole flooring and partitions. This mini-campaign goals to map the hollow-to-ridge transect and analyze the composition of the uncovered bedrock. Polygonal patterns on a neighbouring block had been revealed for the primary time, exhibiting protruding fracture-filling supplies and contrasting textures with beforehand studied strata. MAHLI mosaics and APXS and ChemCam LIBS observations had been deliberate to review polygon centres and ridges, whereas Mastcam gathered stereo photographs of close by partitions.
