FILE - This photo made available by NASA was taken during the first drive of the Perseverance rover on Mars on March 4, 2021. A NASA rover on Mars by chance had its microphone on when a whirling tower of red dust passed overhead and caught the sound. Scientists released the first-of-its-kind audio Tuesday, Dec. 13, 2022. – What's a dust devil sound like on Mars? A NASA rover by chance had its microphone on when a whirling tower of red dust passed directly overhead, recording the racket.
The dust devil came and went over Perseverance quickly last year, thus the short length of the audio, said the University of Toulouse’s Naomi Murdoch, lead author of the study appearing in Nature Communications. At the same time, the navigation camera on the parked rover captured images, while its weather-monitoring instrument collected data.
The microphone picked up 308 dust pings as the dust devil whipped by, said Murdoch, who helped build it.
