Quakes on Mars Reveal New Features of the Planet’s Interior

The recent analysis of data from NASA's InSight lander has unveiled new insights into the internal structure of Mars. Researchers have discovered that the Martian mantle, the layer between the planet's crust and core, is sluggish compared to Earth's, suggesting differences in the planet's thermal and chemical composition. Additionally, the data indicates that Mars has a solid inner core, similar to Earth's. This finding provides valuable information about the evolution and dynamics of the Martian interior, which has implications for understanding the planet's magnetic field and potential habitability. The study's findings contribute to our understanding of the fundamental differences between Earth and Mars, and how these differences have shaped the two planets' geological histories. This knowledge may also inform future exploration of Mars and the search for signs of past or present life on the planet.
