Perseverance records sound of dust devil
For the first time scientists have used the microphone on the Mars rover Perseverance to successfully record the sound of dust devil as it flowed overhead.
I have embedded a video of the recording below. The research paper can be read here.
Dust devils on Mars, while much less dense in its very thin atmosphere, are generally much larger than found on Earth.
The dust devil recently detected by Perseverance was 25 meters wide and 118 meters tall (82 feet by 387 feet), putting it squarely in the average zone in terms of size for Martian dust storms. But they can grow much bigger, too, as dust on Mars can be whipped up in huge global dust storms.
The data also picked up the sound of dust particles hitting the microphone, which will allow the scientists to measure the density of the devil.
