NASA can now say what a dust devil sounds like on Mars. A NASA rover had its microphone on by chance when a whirling tower of red dust passed directly overhead, recording the racket.It is about 10 seconds of not only rumbling gusts of up to 40kph (25mph), but the pinging of hundreds of dust particles against the rover Perseverance. Scientists released the first-of-its-kind audio Tuesday.“We hit the jackpot” when the rover’s microphone picked up the noise made by the dust devil overhead, the study’s lead author Naomi Murdoch of the University of Toulouse, told AFP.
