NASA's Curiosity rover has captured breathtaking images of a Martian dawn, revealing mysterious cliffs emerging from the darkness. Striking blue hues appear in the foreground as the morning light illuminates a series of crags known as yardangs in the distance. The striking scene was snapped at 8.30am Mars time on August 11, the 4,982nd Martian day of the rover's lonely pilgrimage across the Red Planet.
