About this work
Changes on the Martian surface are detected by imaging the same area more than once. In this image acquired on May 13, 2018, NASA's Mars Reconnaissance Orbiter observes several new dust avalanches on the slopes of ridges within the Olympus Mons Aureole. These changes occurred within six years. (Also see the animated GIF). Dust avalanches create slope streaks that expose darker materials usually hidden below a lighter-toned layer.
