Single seismometer structure Because of the lack of direct seismic observations, the interior structure of Mars has been a mystery. Khan et al., Knapmeyer-Endrun et al., and Stähler et al. used recently detected marsquakes from the seismometer deployed during the InSight mission to map the interior of Mars (see the Perspective by Cottaar and Koelemeijer). Mars likely has a 24- to 72-kilometer-thick crust with a very deep lithosphere close to 500 kilometers. Similar to the Earth, a low-velocity… 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. 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. Expand
The interior of Mars revealed
TLDR
These studies provide the first direct observations of the crust, mantle, and core structure on another rocky planet, for which the results and implications can be compared and contrasted with the characteristics of Earth. Expand
The Tharsis mantle source of depleted shergottites revealed by 90 million impact craters
TLDR
It is shown that Tooting and 09-000015 craters are the most likely source of the depleted shergottites ejected 1.1 million year ago, implying that a major thermal anomaly deeply rooted in the mantle under Tharsis was active over most of the geological history of the planet, and has sampled a depleted mantle, that has retained until recently geochemical signatures of Mars’ early history.

The Tidal-Thermal Evolution of the Pluto-Charon System
The existence of subsurface oceans on the satellites of the giant planets and Trans-Neptunian objects has been predicted for some time. Liquid oceans on icy worlds, if present, exert a considerableExpand
Emerging Directions in Geophysical Inversion
Geophysics is built upon indirect information. We cannot travel deep into the Earth to directly measure rheological properties, nor journey back through geological time to record the planet’sExpand

Elemental Composition of the Martian Crust
TLDR
Spacecraft data suggest that martian meteorites are not representative of older, more voluminous crust and prompt questions about their use in defining diagnostic geochemical characteristics and in constraining mantle compositional models for Mars. Expand
