The second attempt at drilling Mojave has been succesfull by both the minidrill and main drill hole (diameter 1.5 cm, depth ~6 cm). Now we are analysing the tailings with ChemCam and APXS. We will get X-ray diffraction identification from the extracted powder. Mojave may have formed with more evaporating water, in acid conditions rather than the more neutral conditions that we studied in the underlying horizons like Yellowknife Bay.
