The results of the research of Japanese scientists can wipe out all previous ideas about the creation of the world.

A group of scientists from Tokyo University in a new study described the details of seismic activity of Mars. The results can erase past theories about the formation of the red planet and to provide detailed information about its composition, writes “Popular mechanics”.

Fourth planet from the Sun is from us at a distance of from 55 million to 400 million kilometers, depending on the orbital position. But still Mars is too far away to run to it space ships for any reason, what part of Mars exploration are on the Earth, and scientists simulate Martian conditions.

Keisuke Nishida, associate Professor of Earth Sciences and planets, the University of Tokyo, and his colleagues simulated the conditions in the topmost layer of the core of the red planet with molten metal: iron-sulfur alloy. His temperature was up to 1500 degrees centigrade at a pressure of 13 GPA. Using a diversified press, the researchers were able to measure seismic activity on Mars. Nishida recorded P-waves moving through the alloy with the speed of 4680 meters per second, and photographed the process using x-rays at two synchrotron installations.

The ability to pass through rock at a rate of 13 times the speed of sound in air (343 m/s), P-waves create the first push. S-waves are called secondary waves responsible for the second push they are used to determine the distance to the earthquake focus — the point of its origin.

“Due to technical reasons it took us more than three years to collect the required ultrasound data, and I am very glad, said Nishida. Experiments under high pressure in the micro-scale help to explore large planets and their evolution”.

Scientists have long suspected that Mars has a core of iron and sulfur, but given that the monitoring in place is not possible, seismic waves allow us to “travel” under the planet’s surface.

Lander, NASA InSight, which landed on the Martian plains of Elysium Planitia 26 November 2018, is looking for on Mars seismic activity, to learn more about the earth and how was formed the rocky planets of the solar system. However, according to Nishida, “Even with seismic data [by InSight] in the data there is a significant gap. We needed to know the seismic properties of the iron-sulfur alloy, which is believed to be is the core of Mars.”

Using the results of the research Nishida and his team, planetary scientists can read seismic data of Mars to find out whether the core of the red planet from an alloy of iron and sulfur.

“If not, we learn something new about the origin of Mars,’ said Nishida. For example, if the core of Mars is composed of silicon and oxygen, Mars, like Earth, has experienced a collision with a space object larger in the period of its formation. So, what made Mars and how it formed? I think we’re going out.”
