The ChemCam campaign at the fluvial sedimentary outcrop ‘‘Shaler’’ resulted in observations of 28
non-soil targets, 26 of which included active laser induced breakdown spectroscopy (LIBS), and all of
which included Remote Micro-Imager (RMI) images. The Shaler outcrop can be divided into seven facies
based on grain size, texture, color,...
A suite of eight rocks analyzed by the Curiosity Rover while it was stopped at the Rocknest sand
ripple shows the greatest chemical divergence of any potentially sedimentary rocks analyzed in the early
part of the mission. Relative to average Martian soil and to the stratigraphically lower units encountered as...
Abstract: The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in...
