CAPE CANAVERAL, Fla. (AP) — 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. 

It's about 10 seconds of not only rumbling gusts of up to 25 mph (40 kph), but the pinging of hundreds of dust particles against the rover Perseverance. Scientists released the first-of-its-kind audio Tuesday. 

It sounds strikingly similar to dust devils on Earth, although quieter since Mars’ thin atmosphere makes for more muted sounds and less forceful wind, according to the researchers.  

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.
