'Earthquake' is observed for the first time on Mars
by
Mars is a global planet belonging to the solar system, and it has been pointed out that water may have existed and some microorganisms were alive . Attempts to explore such Mars have been ongoing for many years, and finally NASA announced that it had observed earthquakes for the first time on Mars.

NASA launched the Mars Rover Insight on May 5, 2018, and on November 26, 2018, Insight succeeded in landing on the Elysium Plains near the equator of Mars. The site sent the first photo from Mars shortly after landing, and the photo shows the horizon, a part of the airframe, and the particles of Mars attached to the dust cover.

The main mission is to install a seismograph on the surface of Mars and measure the temperature inside Mars, and to carry out geological research on Mars. Finally, on April 6, 2019, more than four months after landing, Insight succeeds in observing earthquakes on Mars. No earthquake has been observed on Mars so far, and this observation is the first in history.
The shaking was very weak, but NASA's planet scientist Renee Weber said, 'Although it's still in the early stages of the mission, the Mars earthquake is an earthquake on Earth rather than the moonquake that occurs on the moon. It seems to be close to. ' So far, it has not been clarified whether the sway originates from the interior of Mars or it is caused by a collision such as meteorites.
Bruce Banerdt, a researcher at NASA's Jet Propulsion Laboratory and leading an Insight project, said, 'We have collected background noise on Mars, but this earthquake observation is We have developed a new field of
In order to observe the earthquakes on Mars, Insight used French instruments, placed in the wind-protecting dome of three very sensitive seismographs. Initially, only the vibration caused by the wind blowing above the instrument was being measured, but it is believed that the vibration observed on April 6 came from the interior of Mars.
'What we observed this time was something we had not observed before,' said Mark Panning, a planetary seismologist at the Jet Propulsion Laboratory. In addition to the April 6 shake, Insight also observed quakes on 14 March, 10 April and 11 April, but this is fainter than the April 6 shake. It can not be said that it is an earthquake on Mars.
At the time of writing, it is unclear what cause the earthquake was caused by, but the ultimate purpose of the Insight is to track how seismic energy was emitted and to understand the internal structure of Mars is. Insight is planning to continue observation on Mars for almost two years, and new earthquake data may be collected in the future.
