Life on Mars????

At Space.com, they have updates on what is going on, on Mars.

No, they didn't find any fossils, but apparently the area the rover Opportunity landed was once the edge of a salty sea. This seems to indicate Mars at one time may have been warmer and wetter.

While I don't think they will find any life or evidence life ever existed on Mars, it is still interesting to see how a planet can change over many years.
