NASA shares the shocking sound of a meteor crashing on Mars
NASA remains focused on discovering all the mysteries of Mars and knowing everything related to the red planet for a future human landing. Now, has shared the sound of a meteorite crashing into the Martian surface.
This time, it was the US space agency’s InSight lander that detected seismic waves from four space rocks that crashed into the inner planet furthest from the Sun in 2020 and 2021.
According to the study published this Monday, September 19, in Nature Geoscience and quoted in La Tercera, they are the first impacts detected by the spacecraft’s seismometer since InSight landed on Mars in 2018 and it is also the first time seismic and acoustic waves have been detected on the planet.
The report adds that the impacts ranged between 85 and 290 kilometers from InSight’s location, a region of Mars called Elysium Planitia. The first of the four confirmed meteorites entered the star’s atmosphere on September 5, 2021 and exploded into at least three fragments, each of which left a crater.
In the following video you can hear the roar of the meteorite colliding with Mars.
Crater detection and sound check
NASA’s Mars Reconnaissance Orbiter flew over the estimated impact site to confirm the location, revealing three dark spots on the surface.
The orbiter team then used the High Resolution Imaging Science Experiment (HiRISE) camera to get a color close-up of the craters.
Ingrid Daubar, co-author of the article and Mars impact specialist, spoke about it in a statement from the space agency: “After three years of InSight waiting to detect an impact, those craters looked beautiful.”.
After a thorough investigation, scientists were able to confirm that three more Mars impacts occurred on May 27, 2020, February 18, 2021 and August 31, 2021, hoping to detect more meteor impacts on the Martian surface, located next to the main asteroid belt of the Solar System.
