NASA detects for the first time the sounds of meteors impacting the surface of Mars
A NASA probe has been able to monitor the sounds of meteors impacting the surface of Mars over the past two years.
These sounds are the first effects detected by NASA's seismometer for the discovery of Mars since the landing of the "Insight" probe on the "red planet" in 2018.
It is also the first time that seismic and sound waves resulting from a collision have been detected on the surface of Mars, according to the British newspaper, "Daily Mail", on Tuesday.
And the newspaper said that “NASA” issued a recording of the impact of a meteorite on the surface of Mars , with a distinctive sound that was repeated three times as space rocks entered the atmosphere of the red planet and then exploded into pieces and collided with the surface.
The first meteorite entered the atmosphere of the red planet on September 5, 2021 and exploded into three fragments, each leaving a crater behind.
NASA's Mars Reconnaissance Orbiter flew over the impact site to confirm the location and then a black and white camera was used to detect three dark spots on the surface.
After locating these dark spots, the orbiter team used a high-resolution imaging camera. For a color close-up of these craters.
Scientists found 3 more impacts on May 27, 2020, February 18, 2021 and August 31, 2021. The researchers did not understand why no more meteorite impacts were discovered on Mars.
The Insight team speculates that other effects may have been masked by wind noise or seasonal changes in the atmosphere. Scientists expect to find more effects to come.
It is known that Mars lies next to the main asteroid belt of the solar system, which provides a large stock of space rocks. Because Mars' atmosphere is 1% as thick as Earth's, more meteorites pass through it without disintegrating.
