For the first time, the scientific community has been able to know what the seismic and acoustic waves left by the impact of a meteorite on Mars.
In 2018, NASA’s InSight probe landed on the surface of the Red Planet and, between 2020 and 2021was able to capture the fall of four rocks coming from space.
An article published this Monday in the journal ‘Nature Geoscience’ details that these impacts occurred between 53 and 180 miles (85 and 290 kilometers) from InSight, in an area of Mars known as Elysium Planitia.
The images and sounds that have transpired correspond to a meteoroid -as it is called before crossing the atmosphere and touching the ground- that reached Mars on September 5, 2021 and split into three fragments upon exploding. Each of them left a crater.
The Reconnaissance Orbiter NASA Mars lander flew over the impact site to confirm the location. The orbiter’s black-and-white camera revealed three dark spots on the surface.
So the team used a high-resolution camera (HiRISE) to get a color close-up of the craters. “After waiting three years after InSight arrived to detect an impact, those craters looked beautiful,” he said. Ingrid Daubar, of Brown University, co-author of the aforementioned article.
Scientists have confirmed at least three other impacts: the May 27, 2020, February 18, 2021 and August 31, 2021.
Mars sits next to main asteroid belt of the Solar Systemwhich causes a good number of space rocks to crash on the planet’s surface.
