It became known how the bowels of Mars are arranged

InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, formerly Geophysical Monitoring Station- GEMS) - NASA mission in

as part of the Discovery program to deliver a research lander with a seismometer to Mars. MissionInsightdesigned to study the internal structure and composition of the Red Planet. The estimated operating life of the device is 728 days. 

Thanks to the observations, scientists were able to begin mapping the interior of a planet other than Earth for the first time. 

In particular, scientists have found that the liquid coreMars has an unusually low density, indicating the presence of a relatively small proportion of heavy elements in its matter. Also, scientists did not record a large amount of radioactive substances in the planet's mantle.

The thickness of the first layer of Mars' crust is only8 kilometers. The next layer reaches a depth of 20 km, which is small compared to the typical thickness of the crust on Earth. We assume that it may have a third layer, whose boundary is located at a depth of 39 km.

In addition, planetary scientists did not find insideThe mantle of Mars is two separate layers with different mineral composition and properties, they are similar to those found in the bowels of the Earth. For this reason, the core of the fourth planet in the solar system must have cooled rapidly in the past.

Scientists hope that the new data will allow us to learn the history of the evolution of Mars, as well as help to better understand the place of the Earth in the solar system.
