The Interior exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) Mission will focus on Mars’ interior structure and evolution. The basic structure of crust, mantle, and core form soon after accretion. Understanding the early differentiation process on Mars and how it relates to bulk composition is key to improving our understanding of this process on rocky bodies in our solar system, as well as in other solar systems. Current knowledge of differentiation derives… Expand
Initial results from the InSight mission on Mars
NASA’s InSight (Interior exploration using Seismic Investigations, Geodesy and Heat Transport) mission landed in Elysium Planitia on Mars on 26 November 2018. It aims to determine the interiorExpand
The seismicity of Mars
The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission landed in Elysium Planitia on Mars on 26 November 2018 and fully deployed its seismometer by theExpand
Thickness and structure of the martian crust from InSight seismic data
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
Upper mantle structure of Mars from InSight seismic data
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
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.

Crustal and time-varying magnetic fields at the InSight landing site on Mars
Magnetic fields provide a window into a planet’s interior structure and evolution, including its atmospheric and space environments. Satellites at Mars have measured crustal magnetic fieldsExpand
Constraints on the shallow elastic and anelastic structure of Mars from InSight seismic data
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. AtExpand
Geology of the InSight landing site on Mars
The surficial geology of the landing site is characterized and observations are consistent with expectations made from remote sensing data prior to landing indicating a surface composed of an impact-fragmented regolith overlying basaltic lava flows. Expand
Constraints on Thermal History of Mars From Depth of Pore Closure Below InSight
Planetary crusts undergo viscous closure of pores at depth; if the thickness of this porous layer can be measured, constraints on crustal thermal evolution can be derived. We apply a pore closureExpand
Impact-Seismic Investigations of the InSight Mission
Impact investigations will be an important aspect of the InSight mission. One of the scientific goals of the mission is a measurement of the current impact rate at Mars. Impacts will additionallyExpand


Geodesy constraints on the interior structure and composition of Mars
Abstract Knowledge of the interior structure of Mars is of fundamental importance to the understanding of its past and present state as well as its future evolution. The most prominent interiorExpand
The deep interior of Venus, Mars, and the Earth: A brief review and the need for planetary surface-based measurements
Abstract A comparison of the internal structure of Earth-like planets is unavoidable to understand the formation and evolution of the solar system, and the differences between Earth’s, Mars’, andExpand
Thermal evolution and Urey ratio of Mars
The upcoming InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission, to be launched in 2016, will carry out the first in situ Martian heat flux measurement,Expand
A geophysical perspective on the bulk composition of Mars
We invert the Martian tidal response and mean mass and moment of inertia for chemical composition, thermal state, and interior structure. The inversion combines phase equilibrium computations with aExpand
Estimates of seismic activity in the Cerberus Fossae region of Mars
[1] The 2016 NASA InSight lander is the first planetary mission designed to study the deep interior of Mars. InSight's Seismic Experiment for Interior Structure (SEIS) package will quantify globalExpand
The lunar moho and the internal structure of the Moon: A geophysical perspective
Abstract Extraterrestrial seismology saw its advent with the deployment of seismometers during the Apollo missions that were undertaken from July 1969 to December 1972. The Apollo lunar seismic dataExpand
Geophysical constraints on the composition and structure of the Martian interior
[1] Most recent Martian interior structure models are based on the planet's polar moment of inertia C, although the mean moment of inertia I is required for constructing spherically symmetric modelsExpand
Elemental Composition of the Martian Crust
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
Excavation of the lunar mantle by basin-forming impact events on the Moon
Abstract Global maps of crustal thickness on the Moon, derived from gravity measurements obtained by NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, have shown that the lunar crustExpand
