Mars’ Curiosity rover has been wandering around the plant taking images and observations of the Martian atmosphere. While it is thin, the rover has been able to capture numerous images of clouds.

The clouds in this picture on Mars are higher and are probably made of frozen carbon dioxide, according to NASA scientists. You can read more at and at
