US EditionMarsquakes Indicate a Solid Core for the Red Planet, Just Like Earth: Study
Mars has a solid inner core about one-fifth its radius, similar to Earth's, but its slow crystallization may explain why Mars lacks a magnetic field today, scientists say.
- Mars' inner core is solid and made of metal, similar to Earth's core, as revealed by a Chinese-led research team using NASA's InSight data.
- The Martian inner core, approximately 380 miles in radius, is mostly solid metal, indicating a composition likely including iron and nickel.
- Further studies are needed to understand Mars' core and its implications for the planet's magnetic field, as noted by Daoyuan Sun.
- The research was based on seismic readings from NASA's InSight lander, which recorded over 1,300 marsquakes before 2022.

Despite the difficulties in research, a new study reveals the existence of a solid internal core, indicating that Marte has a nucleo-manto-like structure.
'We've never seen...' — Marsquakes reveal stunning structures hiding inside the red planet
The interiors of Mars have chunks and blobs of ancient rocks that could have developed to form planets. The discovery was made when scientists were scanning through the data of NASA's InSight lander. How did they manage to remain the same for over 4.5 billion years?
A team of scientists led by Chinese researchers has discovered that the innermost core of Mars is solid, a feature that resembles the core of our planet. This finding, based on data collected by NASA's InSight probe, was published in Nature magazine and provides new information on the inner structure of the red planet.
Mars has a solid core, resolving a longstanding planetary mystery
NASAScientists have discovered that Mars has an interior structure similar to Earth’s. Results from Nasa’s Insight mission suggest that the red planet has a solid inner core surrounded by a liquid outer core, potentially resolving a longstanding mystery. The findings, which are published in Nature, have important implications for our understanding of how Mars evolved. Billions of years ago, the planet may have had a thicker atmosphere that allow…
