The POT has published the sound of a meteor impact on the surface of Mars. That impact, in addition, generated 3 new craters on the surface of the ‘Red Planet’ and thanks to this revelation it has been possible to know, for the first time, what the seismic and acoustic waves of an impact on Mars are like.
The Space Agency explains in an article published this Monday in the magazine ‘Nature Geoscience’ that has been achieved thanks to the probe insight. As they explain, 4 meteoroids (the name they receive before hitting the ground) have been confirmed, of which one of them, the one that entered the atmosphere on September 5, 2021, made the “most spectacular” entry because it exploded in 3 fragments that caused 3 different craters.
NASA clarifies that these impacts were detected from a region called Elysium Planitia, where the probe is located, and that the impacts ranged from 85 and 290 kilometers from the point where the device is located. A reconnaissance orbiter then flew over the site to confirm impact and a high-resolution camera was used to obtain color close-ups of the craters.
Analyzing all the data, the scientists have concluded that before this there were already 3 other impacts that occurred on May 27, 2020; on February 18, 2021; and August 31, 2021. Another reason why it has been detected is because the atmosphere of Mars it is only 1% thicker than that of the Earth and does not allow bodies to disintegrate before touching the surface.
Similarly, scientists suspect that there may have been more impacts but whose sound has not been detected by changes in the atmosphere or by wind noise. Also, all meteorite impacts have produced small earthquakes no larger than 2 degrees. They also point out that Mars is located near the main belt of solar system asteroids and that provides rocks to the planet, many of which impact.
This is how the impact on Mars sounds
NASA has published a video in which you can hear the impact:
