How Mars was born? New study comes out.

A team of researchers from the University of Tokyo has revealed details about seismic activity of Mars for the first time in a new study. These results can make or break the theories surrounding the origin of the red planet and provide details about its structure.

The fourth rock from the Sun may be one of the worlds closest to us - swinging between 34 million and 249 million miles (55 million and 400 million kilometers), depending on its position and the position of the Earth relative to our star - but it Often it is much safer and less expensive to test the red planet through simulations on Earth than to launch a spacecraft on space.

Nobody knew more than Keikoku Nishida, an assistant professor in the Department of Earth and Planetary Sciences, and his team, who mimicked the conditions on the planet's upper reaches with the help of a molten and pushed them deeper into the Red Planet. Iron-sulfur alloy, which he brought to a scorching temperature of 2,732 ° F (1,500 ° C).

They were able to measure seismic activity, crushing the molten mixture at a pressure of 13 gigapascals using a multi-anvil press. In this case, Nishida captured P-waves traveling through the alloy at a velocity of 15,354 ft (4,680 m) per second and took action photos using X-ray beams from two synchrotron facilities: Photon Factory, which is part of Japan High Energy Accelerator Research Organization, and also Spring-8 in Harima Science Park City, Hirooga Prefecture, Japan.

Those who have experienced earthquakes have felt the effects of the P-Waves and their seismic partner, the S-Wave. 13125 ft per second (343 m / ps) capable of racing through the rock at speeds 13 times faster than the speed of sound through the air, the P-Waves provide the first shock of this earth-shaking event. S-waves - also called secondary waves - are responsible for the second tremor during an earthquake. They can be used to estimate the distance of a quake's focus, or point of origin.

"Due to technical constraints, it took us three years to meet our needs to collect ultrasonic data, so I am very happy now," Nishida said in a statement on May 13. Given the massive scale of this planet, we are effectively simulating it. But microscopic high-pressure experiments help to discover the long-term evolutionary history of macrocell structures and planets. "



Nishida's relief in capturing data is understandable. It has long been suspected that Mars has a core made of iron-sulfur, but given that direct observations are not yet possible, seismic waves allow us to dig deeper, providing a glimpse inside. To travel through the interior of the planet.



NASA's Insight Mars Lander (shortened to name for internal exploration using seismic investigation, geodesy, and heat transport), which landed on the Martian plane Elysium planitia on November 26, 2018, explores Rumble - or seismic activity - in its To know more about How the interior of the planet and the rocky inner planets of the solar system were formed. However, according to Nishida, there are some reasons for the measurement of the lander.


Nishida said that using the findings of Nishida and his team, planetary researchers could read Martian seismic data to find out whether the core of the red planet consisted primarily of iron-sulfur.
