Although the unit Mars Insight NASA provided details to researchers so that they have a detailed view of Mars’ crust, mantle, and core, and the maps did not include information on the geologic structures closest to the surface, information that would be vital to knowing how red appears. The planet was formed However, a group of scientists managed to find the first detailed picture of what is just below the surface of our neighboring planet, thus displaying more than three billion years of history, all this by analyzing the Martian winds.

To create a picture of what was found in the subsurface of Mars, the data captured by the probe was analyzed through the seismograph installed in InSight, the team responsible for doing this research was Marsquarke service, Led by the Public Polytechnic School of Zurich (ETH Zurich), which included the Swiss Seismological Service (SED).

On Mars, ambient noise is caused by wind, which generates small seismic waves when colliding with the surface of the planet, through their analysis, scientists were able to discover that the planet was formed through stages of great volcanic activity, where an upper layer of sand appears about three meters high, followed by about 20 meters of Loose rocks that cracked due to the impact of thousands of meteorites, behind this loose rock, scientists were able to discover deposits ranging from 30 to 75 meters deep, and sediments that indicate Various flows of lava that covered Mars between 1.7 and 3.6 billion years ago.

Using these technologies on Mars soil, far from being new, is an ingenious replica of the tools used on Earth, since noise from ocean waves, winds, and human activity provides data that SED analyzes through various methods that have been in development for decades.

This ground environmental noise helps to determine the local geological structure because it can determine whether the underlying soil has to dampen or amplify seismic waves, and through this method important information can be obtained that allows determining the seismic hazard of a place and analyzing the most unstable areas that can cause Landslides in mountains or lakes.

Through the development of technologies on our planet were developed methods that have provided information for more than three billion years of the geological history of Mars.
