Our Curiosity rover spots a “dust devil” on Mars 💨⁣
⁣
Mars is often a very dynamic place, due to its atmosphere and how it interacts with the surface. Right now, it's the “windy season” in the region where our Curiosity rover is operating. On Aug. 9, one of the rover's navigation cameras captured the frames in this animation showing a spinning, columnar vortex of wind - also known as a "dust devil" - moving across the landscape.⁣

This dust devil appears to be passing through small hills just above Curiosity's present location on Mount Sharp, a peak within Gale Crater. The dust devil is approximately one-third to a half-mile (half-a-kilometer to a kilometer) away, and estimated to be about 16 feet (5 meters) wide. The dust plume disappears past the top of the frame, so an exact height can't be known, but it's estimated to be at least 164 feet (50 meters) tall.⁣
