Mars lies an average of 225 million kilometres from Earth. Its surface is a cold, dusty desert with towering volcanoes, giant canyons, rocky plains, and unusual rock formations.

Every rover and orbiter sent there helps us uncover more secrets of this distant world. #NASA #mars #SpaceX | Space Journey
