Abstract

More than fifty years after Apollo, lunar seismology is entering a new phase driven by renewed
international exploration. Between 2026 and 2030, Chang’e-7, Artemis (LEMS and SPSS), and NASA’s
Farside Seismic Suite (FSS) will deploy a new generation of seismometers, forming the basis of the first
truly international lunar seismic network, with three stations near the South Pole and one on the farside.
This ISSI team will coordinate the scientific and technical framework required to fully exploit this emerging
network. A central objective is to harmonize instrumental documentation and metadata to ensure robust
inter-station analyses, with particular attention to instrument-specific artifacts and environmental noise
sources that may bias joint interpretations. In parallel, the team will evaluate the scientific potential of
combining seismic data with Lunar Impact Flash (LIF) observations from ground-based telescopes,
improving impact localization and constraints on crustal thickness and lateral heterogeneity. By bringing
together instrument specialists and lunar interior modelers, the project aims to link detailed instrument
characterization with geophysical interpretation. Two peer-reviewed publications, focused respectively on
instrumental harmonization and scientific exploitation, will consolidate this effort, maximizing the scientific
return of upcoming missions and establishing the foundations of international lunar seismology for the
coming decade.
