APOD: A Martian Dust Devil Spins By (2023 Nov 07)

Image A Martian Dust Devil Spins By

Explanation: It moved across the surface of Mars -- what was it? A dust devil. Such spinning columns of rising air are heated by the warm surface and are also common in warm and dry areas on planet Earth. Typically lasting only a few minutes, dust devils become visible as they pick up loose red-colored dust, leaving the darker and heavier sand beneath intact. Dust devils not only look cool -- they can leave visible trails, and have been credited with unexpected cleanings of the surfaces of solar panels. The images in the featured AI-interpolated video were captured in early August by the Perseverance rover currently searching for signs of ancient life in Jezero Crater. The six-second time-lapse video encapsulates a real duration of just over one minute. Visible in the distance, the spinning dust devil was estimated to be passing by at about 20 kilometers per hour and extend up about 2 kilometers high.

Are the Martian DD same as the Earth's DD?

I would say that they are caused by cyclonic atmospheric turbulence that suck up dust from the ground just like Earth dust devils, so my answer is "yes"!

This reminded me immediately of the scene in Forbidden Planet where Robbie the robot first greets the United Planets Cruiser C-57D after the saucer-shaped FTL ship lands on planet Altair IV:

Hey! Thanks for the throwback! I was 10 wears old when i first saw it! I was a Space fan back in 1950!
:oops: Oops; brain fart; 1956! How time flies!

I was still mere inchoate "star stuff" in 1956, not having been conceived until 1963. I also might have been about 10 when I first saw Forbidden Planet, and it's still one of my favorite movies. Along with "Colossus: The Forbin Project"

Me too. I even thought the remake with Keeanu Reeves was decent. Klaatu Barada Nikto!
