Scientific American is carrying this new summary of the Mars rover Spirit's first 90 days of exploration. Looks like the crater they'd hope would show signs of water, well, didn't, and neither did the next crater they took a look at. However, geologic features along the way do seem to hint at liquid water on the surface at some point in the past.
