Topographic map of the Martian surface tagged posts

A strong quake in the last year of the NASA Mars InSight mission, enabled researchers at ETH Zurich to determine the global thickness and density of the planet’s crust. On average, the Martian crust much thicker than the Earth’s or the moon’s crust, and the planet’s main source of heat is radioactive.

After more than three years of daily monitoring and with the power levels decreasing on InSight’s seismometer, researchers were rewarded with data from a sizeable Marsquake in May 2022. The surface waves observed from this estimated 4...
