To gain insight into the thickness of the crust of Mercury, we use gravity and topography data acquired by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft to calculate geoid‐to‐topography ratios over the northern hemisphere of the planet. For an Airy model for isostatic compensation of variations in topography, we infer an average crustal thickness of 35 ± 18 km. Combined with the value of the radius of the core of Mercury, this crustal thickness implies that… 
Mercury's low‐degree geoid and topography controlled by insolation‐driven elastic deformation
Mercury experiences an uneven insolation that leads to significant latitudinal and longitudinal variations of its surface temperature. These variations, which are predominantly of spherical harmonic
Evaluating an impact origin for Mercury's high‐magnesium region
During its four years in orbit around Mercury, the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft's X‐ray Spectrometer revealed a large geochemical terrane in
Impact-induced changes in source depth and volume of magmatism on Mercury and their observational signatures
The authors numerically model the formation of post-impact melt sheets and find that mantle convection was weak at around 3.7–3.8 Ga and that the melt sheets of Caloris and Rembrandt may contain partial melting of pristine mantle material.
Buried Impact Features on Mercury as Revealed by Gravity Data
Gravity data provide information about the internal mass distribution of celestial bodies. The latest gravity field model of Mercury, HgM007, has a higher spatial resolution than previously published
Mercury, Moon, Mars
The evolution of the interior of stagnant-lid bodies is comparatively easier to model and predict with respect to the Earth's due to the absence of the large uncertainties associated with the physics
The Low-Degree Shape of Mercury
The shape of Mercury, particularly when combined with its geoid, provides clues to the planet's internal structure, thermal evolution, and rotational history. Elevation measurements of the northern
Magnetic mineralogy of the Mercurian lithosphere
Mercury and Earth are the only inner solar system planets with active, internally generated dynamo magnetic fields. The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER)
Evolution of the interior of Mercury influenced by coupled magmatism‐mantle convection system and heat flux from the core
To discuss mantle evolution in Mercury, I present two‐dimensional numerical models of magmatism in a convecting mantle. Thermal, compositional, and magmatic buoyancy drives convection of


Thickness of the Martian crust: Improved constraints from geoid-to-topography ratios
[1] The average crustal thickness of the southern highlands of Mars was investigated by calculating geoid-to-topography ratios (GTRs) and interpreting these in terms of an Airy compensation model
Crustal thickness and support of topography on Venus
The topography of a terrestrial planet can be supported by several mechanisms: (1) crustal thickness variations, (2) density variations in the crust and mantle, (3) dynamic support, and (4)
Constraining the crustal thickness on Mercury from viscous topographic relaxation
Mercury exhibits long‐wavelength topography which has probably survived for ∼4 Ga. Assuming Airy compensation, the survival of the topography indicates that only certain combinations of crustal
The tides of Mercury and possible implications for its interior structure
The combination of the radio tracking of the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft and Earth‐based radar measurements of the planet's spin state gives three
Depth of faulting on Mercury: Implications for heat flux and crustal and effective elastic thickness
Topographic profiles across a lobate fault scarp on Mercury have been used to constrain the depth of faulting to 30–40 km. Here we use this depth to place constraints on the crustal thickness and
The mechanical and thermal structure of Mercury's early lithosphere
Insight into the mechanical and thermal structure of Mercury's early lithosphere has been obtained from forward modeling of the largest lobate scarp known on the planet. Our modeling indicates the
Thermal evolution of Mercury as constrained by MESSENGER observations
Orbital observations of Mercury by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft provide new constraints on that planet's thermal and interior evolution.
Thermochemical evolution of Mercury's interior
A number of observations performed by the MESSENGER spacecraft can now be employed to better understand the evolution of Mercury's interior. Using recent constraints on interior structure, surface
Tectonism and volcanism on Mercury
Mercury appears to have a tectonic framework and diastrophic history not found on other terrestrial planets explored to date (earth, Mars, and the moon). On the part of the planet viewed by Mariner
Mantle Convection in the Earth and Planets
Mantle Convection in the Earth and Planets is a comprehensive synthesis of all aspects of mantle convection within the Earth, the terrestrial planets, the Moon, and the Galilean satellites of
