NASA’s Curiosity rover is relaying stunning images of Martian dunes.

The robot has entered Sol 1192 and has wheeled into position to inspect active dunes on the Red Planet.

Curiosity’s up-close investigations of dark sand dunes find them up to two stories tall. The dunes are in view as the rover continues to trek up the lower portion of a layered Martian mountain.

Observations from above Curiosity by the NASA Mars Reconnaissance Orbiter show the “Bagnold Dunes” near Curiosity and reveal that individual dunes move as much as 3 feet (1 meter) per Earth year.

Curiosity’s Mastcam Right images of dunes were taken on Sol 1190 December 11, 2015.
