Strange shapes on Mars

American spacecraft sends strange images on the red planet, including blocks of CO 2 ice, sand dunes, cliffs and valleys.

The Mars Reconnaissance Orbiter of NASA is flying around Mars. Its main task is to learn the secret of the history of the red planet. Scientists believe that living activities exist on Mars and they are looking for water on its arid surface.
