After freeing the rover’s arm from the “Atacama” block, we are ready to drill again! The new drill target will represent the same geologic stratum as Atacama, which is the layered sulfate unit above the boxwork structures. We’ve named the new block “Campo Marte” after a natural red sandstone feature in Bolivia, following the theme of choosing target names in this Martian quadrangle from locations near the Uyuni region in South America. The name can be literally translated from Spanish as “Field of Mars” or “Mars Field,” appropriate for a target on Mars. In preparation for drilling, we measured the composition of Campo Marte with the ChemCam LIBS and the APXS as well as obtaining close-up imaging with MAHLI. Additional LIBS rasters provided geochemical data on nearby blocks, including a couple of vein and nodule-like features. As we’ve seen in several rover stops in this unit, the “Paso Malo” block and several others are covered in a prominent polygonal texture.
We’ve also imaged the Campo Marte block from several angles and determined that it’s substantially thicker than the Atacama block, so we’re hoping that its greater mass will keep it on the ground after drilling so that we can withdraw the drill bit normally this time. The team did get some interesting data on the volume and density of the Atacama block from our little adventure but we d …
