Analytical database of martian minerals (ADaMM): Project synopsis and Raman data overview

Abstract

The Mars2020/Perseverance and ExoMars/Rosalind Franklin rovers are bothslated to return the first Raman spectra ever collected from another planetarysurface, Mars. In order to optimize the rovers scientific outcome, the scientificcommunity needs to be provided with tailored tools for data treatment andinterpretation. Responding to this need, the purpose of the Analytical Databaseof Martian Minerals (ADaMM) project is to build an extended multianalyticaldatabase of mineral phases that have been detected on Mars or are expected tobe found at the landing sites where the two rovers will operate. Besides the useof conventional spectrometers, the main objective of the ADaMM database isto provide access to data collected by means of laboratory prototypes simulat-ing the analytical performances of the spectroscopic systems onboard the Mars2020 and ExoMars rovers. Planned to be released to the public in 2022,ADaMM will also provide access to data treatment and visualization toolsdeveloped in the framework of the mentioned space exploration missions. Assuch, the present work seeks to provide an overview of the ADaMM onlineplatform, spectral tools, and mineral collection. In addition to that, themanuscript describes the Raman spectrometers used to analyze the mineralcollection and presents a representative example of the analytical performanceensured by the Raman prototypes assembled to simulate the Raman LaserSpectrometer (RLS) and SuperCam systems.
