Perseverance’s Navigation Camera (Navcam) observations of the direct dust devil encounter: the Navcam scene (the average background image, top panel) and each dust devil image processed to dust amount (five lower panels), masking out only the truly indeterminate areas (gray); the color scale ranges from optical depth, τ = 0 at the bottom (blue) to τ = 0.12 at the top (yellow), and is linear in between; the areas with low signal-to-noise ratio are masked out, and the images also show non-random noise (banding from instrument electronics during readout); the grid on the scene image (top panel) is 5 degrees in local level azimuth and elevation; the darker gray contours are elevation=0 degrees and azimuth=165 degrees.

A spiral-shaped dust storm is visible in this image taken by the High Resolution Stereo Camera (HRSC) imager on ESA’s Mars Express spacecraft. This image, taken on May 26, 2019, depicts the formation of a spiral shape whose main arm is approximately 2,000 km in length. A granular pattern of dust cells is visible in the storm, formed by a process called closed-cell convection. This type of convection is also responsible for some cloud patterns on Earth.
