Compared to Earth, Mars has a thin shell of air, so the formation of clouds in its atmosphere is a rather rare phenomenon. This usually happens during the cold season at the equator.

The very first cloud layer on the Red Planet is located at an altitude of 60 km and consists of ice. And below it, at the level of local mountains, there is a layer of frozen carbon dioxide, as scientists suggest.

Curiosity's black and white images have more detail, but the beauty of the color images is truly mesmerizing.
