A seismograph on Mars has revealed the first detailed glimpse of the interior of the Red Planet, documenting a surprisingly thin crust and a molten core beneath the frozen surface. In a series of articles published this week, scientists reported that the crust of Mars is found in the thickness of the Earth, according to Al Arabiya Net.
The thickness of the Martian mantle between the crust and the core is about half the thickness of the Earth. The core of Mars is taller than scientists expected, although it is smaller than the core of our planet, which is about twice the size of Mars.
These new studies also confirm that the core of Mars is molten. But more research is needed to find out whether Mars has a solid inner core like Earth’s, surrounded by a molten outer core, according to international research teams.
Scientists said stronger earthquakes can help identify multiple underlying layers, according to the Associated Press.
The results are based on around 35 earthquakes recorded by the French seismometer on NASA’s InSight lander, which arrived on Mars in 2018.
The dome seismometer has already detected 733 earthquakes to date, but 35 with magnitudes of 3.0 to 4.0 have served as the basis for these studies.

Most major earthquakes originate in a volcanic region 1,600 km (1,600 km) away where lava could have flowed only millions of years ago.
Even the biggest earthquakes are so weak they can barely be felt on Earth, said Mark Banning of NASA’s Jet Propulsion Laboratory, who participated in the study of the crust.
Banning said he hoped a “big thing” would make it easier to process the data and determine the interior of Mars. “We would like to see bigger events,” he added.
It should be noted that current measurements show that the Martian crust can reach a depth of 12 to 23 miles (20 to 37 km), and the mantle extends for nearly 1,000 miles (1,600 km); The core is relatively light with a radius of 1,137 miles (1,830 kilometers).
