New research using Nasas InSight seismic waves reveals Mars has a solid inner core

New research from NASA's InSight lander, which recorded over 1,300 Marsquakes between 2018 and 2022, suggests Mars possesses a solid inner core, approximately 600 kilometers in radius, surrounded by a liquid outer core. This discovery challenges previous assumptions of a fully liquid core and could reshape our understanding of Mars' past magnetic field and planetary evolution.
