Gully Monitoring
ESP_080786_2270 Science Theme: Mass Wasting Processes

Scientists monitor the many pristine gullies on Mars to find changes and determine the seasons when they are most active. This image will be compared to a prior image with very similar lighting and viewing angles to search for any changes. The cutout has enhanced colors.
