The data collected by NASA’s InSight module is beginning to clear up the mysteries surrounding the planet Mars.

For four years (2018 and 2022), the robot began collecting data until its mission ended last December.

One of the latest discoveries made known is that of the composition of the core.

Jessica Irving, a researcher at the University of Bristol, said in statements to the BBC that the new results made it possible to establish new theories about its composition.

“These first measurements of the … properties of the Martian core have helped us investigate its composition. Rather than just being an iron ball, it also contains a large amount of sulfur and other elements, including a small amount of hydrogen .”

In an article published in the PNAS magazine the core of the planet would be composed of an alloy of liquid iron plus sulfur with smaller fractions of oxygen, carbon and hydrogen.

The scientists came to this conclusion by evaluating data from two earthquakes that struck the other side of the robot.

“Future geophysical missions to Mars will be vital for refining models of the Martian core beyond these early seismological estimates, and a multi-location network of seismometers may prove critical to improving our knowledge of the deep interior.” from Mars,” the study added.

The difference with the core of the earth is that it is liquid on the outside but solid on the inside.
