Uncovering the Mysteries of Mars: New Discoveries on its Crust and Core.

NASA's InSight lander measured the largest marsquake ever recorded in May 2022, revealing that the Martian crust is "like heavy armor" in some locations, according to a new study. The team's research showed that the crust of the Red Planet has a thickness that ranges from an average of 26 to 35 miles (42 to 56 kilometers), but its thickest extent is double that: 56 miles (90 kilometers). The team's discovery of a thick Martian crust in some places also sheds some light on how the planet generates heat, and how this has evolved over the Red Planet's history.
