On Mars, the Space Probe InSight, which was launched by NASA's National Space Exploration Agency, was commissioned Monday by scientists from the United States, France and Germany.
On the way to Mars, the probe made 548 million kilometers in six months.
The Zonde landed near the equator of Mars in the western part of the planet, which is flat and smooth, which facilitates drilling operations. Experts point out that this is the first cosmic probe equipped with devices to study the internal structure of Mars, which seeks answers to questions about the early stages of the development of other planets: Mercury, Venus and Earth 4.5 billion years ago.
The study aims to clarify the information about the internal density of the iron and metal core of Mars to determine if the metal is in a liquid or solid state in the center of the planet. The German scientist's research aims to measure the temperature of the planet about five meters deep to determine the heat source and study if Mars is made up of the same substance as the Earth and the Moon.
The Zonde is equipped with highly sensitive sensors made by French scientists who will study the "pulse" of Mars: seismic waves caused by tremors, meteorite discharges and dust storms. Such measurements on Mars have never been made before, reports Reuters. The Zonde will explore Mars for the next 24 months, approximately one year on Mars.
"The reason we are shooting at Mars is not only the desire to better understand its structure, but also the structure and formation of the Earth," said Bruce Banerd, one of the billion-dollar project researchers, in an interview with Reuters.
Researchers want to find an answer to the question of why Mars, once a relatively warm and humid planet, developed in contrast to Earth, becoming a dry, desert and cold world where there is no life. NASA's lead researcher, James Green, says the answer could be Mars' ancient past, magnetic fields and tectonic activity.
