Analysis of Mars's wind-induced vibrations sheds light on the planet's subsurface properties

Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet's surface. These findings were gained in the framework of NASA's InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners, including the University of Cologne, collaborate. The paper 'The shallow structure of Mars at the InSight landing site from inversion of ambient vibrations' will appeared in Nature Communications on 23 November.
