Abstract | The MESSENGER/Mercury Atmospheric and Surface Composition Spectrometer (MASCS) instrument operated between 2011 and 2015 in orbit around Mercury. During its lifetime, the MASCS instrument produced more than ~4.7 millions of spectra of Mercury’s surface with the Visible Infrared Spectrograph (VIRS), scattered all over the planet, allowing the extensive characterisation of its spectral properties from 300 to 1450 nm, with a spectral resolution of 5 nm.
The PDS archived MASCS DDR data have been ingested in the Mercury Surface Spectroscopy (MeSS) PostGreSQL database (Munoz et al., 2022, this conference), hosted at the European Space Astronomy Centre (ESA/ESAC). In addition, derived data (combined spectra from Besse et al. (2015), and spectral parameters) were also incorporated to this framework. This database framework facilitates a rapid access and extraction of information from many MASCS orbits at once, in order to characterise the spectral properties of surface features (Besse et al., 2020 ; Barraud et al. 2021). It also makes possible to explore the data set in an integrated way through detailed coverage analyses. A set of tools is being developed to ease the access and usage of the data. In this work, we will present the outcome of the coverage analysis performed on the MeSS database.
