Bruce Murray Space Image LibraryDust devils in Gale crater, sol 2215 Dust devils in Gale crater, sol 2215 Curiosity periodically looks across the Martian landscape at the horizon and takes a sequence of images in order to search for transient events that lift dust into the atmosphere. On sol 2215 (30 October 2018), it got lucky, catching several dust devils crossing the view. In this animation, the images have been processed to emphasize changes from the static landscape, making the hard-to-spot dust devil more visible. The animation covers a period of about 30 minutes.
