NASA scientists have recorded the sound of a meteoroid hitting the surface of Mars. In September last year, the US space agency’s InSight instrument recorded the sound of a meteoroid that broke into several pieces as it entered the Martian atmosphere and crashed into the surface of the Red Planet. The impact was so strong that distinct traces of the fall remained on the surface of Mars.
The gurgling sound is explained by the fact that the sound waves from the impact propagated through the dry atmosphere of Mars. Under certain conditions, such as in deserts on Earth, lower sounds travel faster than higher ones. “An observer close to the impact site will hear a ‘bang’, while someone miles away will first hear bass sounds creating a ‘gurgle'” explained on the NASA blog.
With the help of InSight information, the scientists were able to pinpoint exactly where they thought parts of the celestial body had crashed into the soil. Having sent a Martian orbiter to check it, they discovered three craters.
The InSight spacecraft landed on the surface of Mars in 2018 and has since recorded a number of “marsquakes” with varying amplitudes. This information helps scientists in studying the processes occurring in the bowels of the Red Planet. Using data from InSight also allows them to get an idea of what is happening in the immediate vicinity of the planet. In any case, his instruments were able to pick up the sound of a meteoroid exploding as it entered the Martian atmosphere.
