Seismic detection of the martian core [PDF]

open access: yesScience, 2021
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.

Direct Formation of Structural Components Using a Martian Soil Simulant. [PDF]

open access: yesScientific Reports, 2017
Martian habitats are ideally constructed using only locally available soils; extant attempts to process structural materials on Mars, however, generally require additives or calcination.

Field Measurements of Terrestrial and Martian Dust Devils [PDF]

open access: yes, 2016
Surface-based measurements of terrestrial and martian dust devils/convective vortices provided from mobile and stationary platforms are discussed. Imaging of terrestrial dust devils has quantified their rotational and vertical wind speeds, translation ...

Geologic history of Martian regolith breccia Northwest Africa 7034: Evidence for hydrothermal activity and lithologic diversity in the Martian crust [PDF]

open access: yes, 2016
The timing and mode of deposition for Martian regolith breccia Northwest Africa (NWA) 7034 were determined by combining petrography, shape analysis, and thermochronology.

A review of volatiles in the Martian interior [PDF]

open access: yes, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Thickness and structure of the martian crust from InSight seismic data

open access: yesScience, 2021
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.

Martian moons exploration MMX: sample return mission to Phobos elucidating formation processes of habitable planets

open access: yesEarth, Planets and Space, 2021
Martian moons exploration, MMX, is the new sample return mission planned by the Japan Aerospace Exploration Agency (JAXA) targeting the two Martian moons with the scheduled launch in 2024 and return to the Earth in 2029.

What Martian Meteorites Reveal About the Interior and Surface of Mars

open access: yesJournal of Geophysical Research: Planets, 2020
Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total of 262 individual samples originating from at least 11 ejection events.

Properties and models of the Martian bow shock

open access: yes地球与行星物理论评, 2021
Mars does not have a global magnetic field of the internal origin, thus, the solar wind plasma can interact directly with the upper atmosphere and the ionosphere and be shocked with the mass-loading and magnetic pileup processes.

Is the Martian crust also the Martian elastic lithosphere? [PDF]

open access: yesJournal of Geophysical Research: Planets, 2002
Correlations between topography, gravity, and areoid on Mars are used to constrain the crustal and lithospheric thicknesses on the planet. Assuming that the Hellas basin is in isostatic equilibrium with Airy compensation, point correlations between areoid anomalies and topography are used to obtain the mean crustal density and the crustal thickness.
