TL;DR: This article detected reflections of seismic waves from the core-mantle boundary of Mars using InSight seismic data and inverted these together with geodetic data to constrain the radius of the liquid metal core to 1830 ± 40 kilometers.

TL;DR: In this paper, the authors determine the structure of the crust beneath the InSight landing site on Mars using both marsquake recordings and the ambient wavefield, and find that the observations are consistent with models with at least two and possibly three interfaces.

TL;DR: In this paper, the authors used observations of direct (P and S) and surface-reflected (PP, PPP, SS, and SSS) body-wave phases from eight low-frequency marsquakes to constrain the interior structure to a depth of 800 kilometers.

TL;DR: Yang et al. as discussed by the authors detected surface waves from two meteorite impacts on Mars and measured group velocity dispersion along the impact-lander path, obtaining a direct constraint on crustal structure away from the InSight lander.

TL;DR: Yang et al. as discussed by the authors detected a large seismic event with a distinct signature on the surface of Mars, which was confirmed by satellite observations of a newly formed 150-kilometer crater.
