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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Some Indians had a a belief about Dust Devils if the spin in one direction its good of they spin the other way its bad
