A microphone on the Perseverance rover captured eerie audio of a massive dust devil on Mars for the first time

A towering whirlwind of dust passed right over the Perseverance rover as it explored the site of an ancient lake on Mars – and the rover recorded the first sounds of this Martian dust devil using its microphone. Dust devils, or dust whirlwinds, are common on Mars, and they’re part of the weather patterns on the red planet.
A planet-encircling dust storm is what ended the Opportunity rover’s 15-year mission in 2018. “Global dust storms are important for understanding the Martian climate,” Murdoch said. “The acoustic measurements of dust impacts and dust lifting will, therefore, improve our understanding of dust devils and will also help to improve Martian climate models. Understanding dust lifting is also critical for space missions due to the damage that can be caused to hardware.

Mars rover captures 1st sound of dust devil on red planetA 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. Photographed for decades at Mars but never heard until now, dust devils are common at the red planet.
