What does it mean to capture the sounds of meteorites on Mars, and how does the Insight probe work?


NASA’s InSight lander has captured the sounds of Mars and detected the vibrations of four space rocks as they slammed into Mars over the past two years. Also the first time that seismic and sound waves from a collision have been detected on the surface of Mars.

According to the British newspaper, “Daily Mail”, the US Space Agency released a recording of one of the Martian meteorite collisions, with a distinctive sound ringing three times when space rocks enter the atmosphere, explode into pieces and collide with the surface.

Impacts ranged from 53 to 180 miles (85 to 290 kilometers) away from the probe’s stationary location in a region of Mars called Elysium Planitia, a smooth plain north of the planet’s equator.

It entered the atmosphere of the red planet on September 5, 2021 and exploded into at least three fragments, each leaving a crater behind. NASA’s Mars Reconnaissance Orbiter then flew over the estimated impact site to confirm the location.

The black and white context camera was used to detect three dark spots on the surface. After locating these spots, the orbiter team used the High Resolution Imaging Science Experiment Camera, or HiRISE, to obtain a color close-up of the craters.

“After three years of waiting for InSight to detect the impact, these craters looked beautiful,” said Ingrid Dubar of Brown University, a co-author of the new paper on the discovery who specializes in Mars impacts.

Also, after combing through past data, scientists confirmed three more impacts on May 27, 2020, February 18, 2021 and August 31, 2021.
