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.

Amazing that with the air density so much lower it still lofts and circulates the dust particles just like here.

It certainly is intriguing but I find it curious that there is no indication of the dirt devil above the back lying hills.

Yea, with all the effort going into faking these images, they could have done something about that. /sarc

It looked like teleportation. It got brighter before it cut off. Someone or some THING was materializing.

NASA’s Perseverance Mars rover used one of its navigation cameras to capture these dust devils swirling across Jezero Crater on July 20, 2021, the 148th Martian day, or sol, of the mission.
