Curiosity Blog, Sols 4947-4953: Gale Crater Then and Now - NASA Science (.gov)

Earth planning date: Friday, Oct. 1, 2026 The majority of Curiosity plans involve mosaics from Mastcam and ChemCam, chemistry analyses from ChemCam and APXS, images from MAHLI and MARDI, and systematic measurements from REMS, RAD, and DAN. It is only when we stop to drill that we fully live up to our Mars Science Laboratory designation, using CheMin and SAM to analyze Martian rock. This was one such week, where our focus was wrapping up CheMin analysis of a sample from the “Basque Lakes” drill hole (pictured above), preparing SAM for its analysis, and analyzing the sample with the SAM tunable laser spectrometer (TLS). The CheMin data were key to SAM deciding to analyze the sample at all, and SAM will wait to receive the results from the TLS run (measurement of the volatiles present) to decide if they want to follow up with a separate mass spectrometry analysis next week.
