Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: July 18, 2025 | Last Modified: 2025-07-17
The MSL APXS RDR data set contains calibrated spectra and oxide weight percent data derived from observations of the APXS instrument aboard the Mars Science Laboratory rover. Two types of products are included: summed X-ray spectra in counts as a function of energy, and abundance data for a set of standard elements and oxides, derived from the summed spectra. Both product types are given as ASCII text files in comma-separated-value (CSV) format, suitable for reading with spreadsheet software.
