The sky on Mars before dawn is vibrant, adorned with pink and blue clouds. However, as the sun rises, these clouds quickly dissipate, leaving behind a grayish scene. The clouds here are primarily composed of dust, with the blue clouds containing water ice, located about 16 kilometers above the surface. Despite the cloud cover, rain does not fall on Mars. Once the clouds clear, the Martian sky takes on a unique gray hue, as if it has lost its blue canopy.
