As NASA`s Curiosity rover makes its way over the surface of Mars, it`s sometimes accompanied by clouds drifting by in the sky above. Like Earth, the Red Planet has a water cycle, with water molecules moving between the surface and the air, traveling through the atmosphere and coming together to form clouds. The behavior of water-ice clouds on Mars plays a big role in its climate, and this computer simulation shows them forming and dispersing over the course of a Martian day.
