Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

A. Ollila, Olivier Beyssac, A. Fau, O. Forni et autres

Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks. …

Ultramafic float rocks at Jezero crater (Mars): excavation of lower crustal rocks or mantle peridotites by impact cratering?

O. Beyssac, Elise Clavé, O. Forni, S. Udry et autres

Based on observation and data from meteorites and in situ scientific missions, experiments as well as models, the Martian mantle is assumed to share some compositional and mineralogical affinity with the terrestrial mantle. However, there might be subtle differences like the Martian …

SuperCam Raman Activities at Jezero Crater, Mars: Observational Strategies, Data Processing, and Mineral Detections During the First 1000 Sols

G. López-Reyes, J. A. Manrique, Elise Clavé, A. Ollila et autres

Abstract The Mars 2020 Perseverance rover introduced Raman spectroscopy to in situ planetary exploration for the first time when it landed in Jezero crater on Mars in February 2021. The SuperCam instrument onboard Perseverance is a multi‐analytical tool capable of acquiring time‐resolved …

Minimum Sample Size Calculation for Multivariable Regression of Continuous Outcomes in Chemometrics for Astrobiology and Planetary Science

Menelaos Konstantinidis, E.A. Lalla, Juan Carlos Ojeda Manrique, G. López-Reyes et autres

Over the last few decades, prediction models have become a fundamental tool in statistics, chemometrics, and related fields. However, to ensure that such models have high value, the inferences that they generate must be reliable. In this regard, the internal validity of …

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Iván Reyes‐Rodríguez, Sofía Julve‐Gonzalez, Marco Veneranda, J. A. Manrique et autres

ABSTRACT The Atmospheric Chamber for Measurements in Environment (A.C.M.E.) provides a versatile and highly controlled environment for simulating planetary conditions, supporting the testing and calibration of instruments for planetary exploration. In this study, we utilized A.C.M.E. to evaluate the performance of a …
