Interior Of Mars

The current understanding of the interior of mars suggests that it can be modeled with a thin crust similar to earth s a mantle and a core.

Interior of mars. Such certainty has come from measurements of the planet s moment of inertia taken by the nasa spacecraft mars pathfinder. Based on its mean density and the bulk chemistry of terrestrial planets mars is believed to have a dense metallic core and a silicate mantle. The soil of mars also holds nutrients such as sodium potassium chloride and magnesium.

The only thing we know for sure about the interior of mars is that it has a core with a radius of between 1500 and 2100 km says christophe sotin a planetary geophysicist at the university of nantes france. The topmost layer is known as the crust underneath it is the mantle which rests on a solid inner core. It has three distinct layers.

Using four parameters the martian core size and mass can be determined. Going inwards from the outside there is a relatively thin rocky crust a mantle and finally a metal core. This iron ii sulfide core is thought to be twice as rich in lighter elements as earth s.

Current models of the planet s interior imply a core region about 1 794 km 1 115 mi 65 km 40 mi in radius consisting primarily of iron and nickel with about 16 17 sulfur. The mantle is the darker material between the core and the thin crust.

Artist s concept of the interior of mars shows a hot liquid core that is about one half the radius of the planet. The core is mostly made of iron with some possible lighter elements such as sulfur. Artist s rendition showing the inner structure of mars.
