Cape Canaveral, Dec. 13 (US): What does a dust devil sound like on Mars? A NASA roaming microphone was triggered by accident when a tower of red dust passed just above his head, recording the paddle.
It takes about 10 seconds for not only strong gusts of up to 25 mph (40 km/h), but hundreds of dust particles whizzing against the rover’s tenacity. Scientists made the first sound of its kind on Tuesday.
It sounds strikingly similar to dust devils on Earth, though it’s quieter because Mars’ thin atmosphere makes sounds more muffled and winds less strong, according to the researchers.
The dust devil came and went over persistence quickly last year, and thus the short length of the sound, said Naomi Murdoch of the University of Toulouse, lead author of the study that appears in Nature Communications.
At the same time, a navigation camera on the parked rover took pictures, while a weather observatory collected data, the AP reports.
Dust devils have been photographed on Mars for decades and have not yet been heard of, and they are common on the Red Planet.
This was in the middle range: at least 400 ft (118 m) high and 80 ft (25 m) wide, traveling at 16 ft (5 m) per second
Murdoch, who helped build it, said the microphone picked up 308 sounds of dust as the dust devil whipped.
With the rover’s SuperCam microphone being played for less than three minutes every few days, Murdoch said she was “definitely lucky” for the dust devil to appear when it appeared on Sept. 27, 2021. She estimates there was only a 1-in-200 chance of catching a dust sound. evil.
Murdoch said these recordings allow scientists to study Martian winds, atmospheric turbulence and dust movement now as never before. The results “show” how valuable acoustic data is in space exploration. “
