Mars’s seismic activity and noise have been monitored since January 2019 by the seismometer of the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander. At night, Mars is extremely quiet; seismic noise is about 500 times lower than Earth’s microseismic noise at periods between 4 s and 30 s. The recorded seismic noise increases during the day due to ground deformations induced by convective atmospheric vortices and ground-transferred wind-generated… Expand

The shallow structure of Mars at the InSight landing site from inversion of ambient vibrations.
TLDR
A classical seismological technique of inverting Rayleigh wave ellipticity curves extracted from ambient seismic vibrations is applied to resolve, for the first time on Mars, the shallow subsurface to around 200 m depth. Expand
Thickness and structure of the martian crust from InSight seismic data
TLDR
The structure of the crust beneath the InSight landing site on Mars is determined using both marsquake recordings and the ambient wavefield by analyzing seismic phases that are reflected and converted at subsurface interfaces, finding that the observations are consistent with models with at least two and possibly three interfaces.

Upper mantle structure of Mars from InSight seismic data
TLDR
The seismic constraints with geodynamic models predict that, relative to the primitive mantle, the crust of Mars is more enriched in heat-producing elements by a factor of 13 to 20 and has a moderate-to-elevated surface heat flow. Expand
Seismic detection of the martian core
TLDR
A preliminary structure of Mars is provided that helps to constrain the different theories explaining the chemistry and internal dynamics of the planet and implies a martian mantle mineralogically similar to the terrestrial upper mantle and transition zone but differing from Earth by not having a bridgmanite-dominated lower mantle.
