Water, water everywhere... Well at least there used to be.

NASA announced today that they have enough evidence to conclude that water was once abundant at the Opportunity landing site. While this was a big and important announcement, it is hardly a sunrise. This is exactly what scientists have long suspected, and what the rovers were sent to confirm. The evidence comes in the form of a rock that exhibits layers of sediment containing salt, and other minerals indicative of a body of water that has evaporated. What is important about this discovery is that it tells NASA where to look for signs of life in future missions.
