It shows Mars during the transition between spring and summer in the northern hemisphere (summer solstice). The north polar carbon dioxide (dry ice) frost cap is rapidly evaporating from solid to gas, revealing a much smaller permanent water ice cap. Bright water ice clouds are visible across the center and along the bottom of the image. (View Less)
