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.
