We are all in the gutter, but some of us are looking at the stars.

Making Martian clouds on Earth
Massachusetts Institute of Technology said:
At first glance, Marsí clouds might easily be mistaken for those on Earth: Images of the Martian sky, taken by NASAís Opportunity rover, depict gauzy, high-altitude wisps, similar to our cirrus clouds. Given what scientists know about the Red Planetís atmosphere, these clouds likely consist of either carbon dioxide or water-based ice crystals. But itís difficult to know the precise conditions that give rise to such clouds without sampling directly from a Martian cloud.
Researchers at MIT have now done the next-best thing: Theyíve recreated Mars-like conditions within a three-story-tall cloud chamber in Germany, adjusting the chamberís temperature and relative humidity to match conditions on Mars ó essentially forming Martian clouds on Earth.
