The National Aeronautics and Space Administration (NASA) of the USA for the first time managed to record the sounds of the so-called Martian “dust devil”, a small sand vortex, which turned out to be similar in properties to terrestrial counterparts, using the Perseverance rover.
Although this became known only now, the recording was made in September 2021. In addition, pictures of the approaching vortex were taken. According to scientists, the height of the sand vortex, which was moving at a speed of 40 km/h, was about 118 m, and the diameter was about 25 m. That is, in terms of its parameters, it almost did not differ from terrestrial analogues, although it was much smaller in strength due to extreme low atmospheric pressure on the Red Planet.
