Recent research indicates that Mars has a solid inner core composed of metal, similar to Earth's core. This conclusion is based on seismic data collected by NASA's InSight lander, which recorded over 1,300 marsquakes before its shutdown in 2022. The findings suggest that Mars' inner core is surrounded by a molten outer core, with the inner core extending approximately 380 miles in radius. While the study highlights similarities between Mars and Earth, questions about the exact composition and formation of Mars' core remain. Further exploration and data collection will be necessary to deepen our understanding of Mars' geological history and its magnetic field.
