Resonances of the InSight Seismometer on Mars

Kenneth Hurst et al.

Summary: After the deployment of InSight seismometer on Mars, resonances at various frequencies were discovered, which are important for high frequency analysis and phase measurements of seismic data. These findings may also contribute to the development of future planetary seismometers.

Thickness and structure of the martian crust from InSight seismic data

Brigitte Knapmeyer-Endrun et al.

Summary: The study analyzed marsquake recordings and ambient wavefields to determine the crustal structure beneath the InSight landing site on Mars. The average thickness of the Martian crust was found to be between 24 and 72 kilometers, with thicker models consistent with observed heat-producing elements at the shallow surface and thinner models requiring greater concentration at depth.

Upper mantle structure of Mars from InSight seismic data

Amir Khan et al.

Summary: By analyzing seismic data from Mars, researchers have constrained the planet's internal structure and thermochemical state, revealing that Mars has a thicker thermal lithosphere than Earth and a much higher enrichment of heat-producing elements in the crust than previously thought.

Seismic detection of the martian core

Simon C. Stahler et al.

Summary: The study found that Mars has a core radius of around 1830 +/- 40 kilometers, with a density of 5.7 to 6.3 grams per cubic centimeter. The martian mantle is mineralogically similar to Earth's upper mantle and transition zone, but lacks a bridgmanite-dominated lower mantle, suggesting a different geological structure. This also affects the seismic observations of potentially active regions on Mars.
