Study Reveals Mars Possesses Solid Inner Core

(MENAFN) A recent collaborative study by Chinese and U.S. scientists has revealed that Mars possesses a solid inner core, overturning long-held assumptions about the planet’s internal structure.

Published in Nature, this groundbreaking research provides the first concrete evidence of a solid inner core on Mars, calling into question existing models of how the Red Planet formed and cooled over time.

By analyzing seismic data from NASA’s now-retired InSight mission, scientists detected a solid core approximately 600 kilometers (373 miles) in radius, representing about 18% of Mars’ total radius—comparable in proportion to Earth’s inner core.

This discovery serves as a crucial reference point for understanding the thermal and chemical composition of Mars.

The new insights address a significant gap in knowledge regarding Mars’ deep interior, while also reviving discussions about the possibility that Mars, like Earth, once experienced plate tectonics.

The study indicates that the inner core likely contains a concentration of light elements separated from the outer core through crystallization processes.

Furthermore, the research highlights that the formation of Mars’ inner core may hold vital clues to the evolution of its magnetic field, potentially offering broader understanding of dynamo mechanisms across planetary bodies.
