Clouds on Mars!
Yes, that's right. The Mars rover Opportunity has snapped some amazing pictures of what appear to be Martian cirrus clouds, and it's not seeing hallucinations. Scientists theorize that these clouds are only produced when Mars is at its farthest point from the Sun, when it receives much less sunlight. The clouds are believed to be made of, yes, frozen water. Martian wind is moving them along at a nice speed of 20 miles per hour.

This comes along the same time that Spirit found some interesting rocks on Mars. A mineral called [w:goethite|goethite]] (never before found on Mars) was in one rock, and another had an amazing chemical structure.

Those rovers have certainly turned up more than we thought they would.
