A massive marsquake measured by NASA's InSight lander suggests the Red Planet  crust is "like heavy armor" in some locations, a new study suggests.

The seismometer of the NASA InSight lander, whose mission concluded in December 2022, spent three years measuring seismic waves on Mars. Its work included spotting the largest marsquake ever recorded in May 2022: a quake 4.6 in magnitude.
