Mars Rover Sniffs First Hint of Water?

mhw25 writes "It is reported that the Mars rover Spirit is already well into its scientific mission, and may be detecting hints of water. The mini-Thermal Emission Spectrometer has returned its first image, with probable evidence of carbonates and hydrated minerals. We may know more after the rover rolls off its landing base, after making a 120 degree turn to avoid the airbag blocking its front ramp, to start analyses on soil from Thursday or Friday. An ongoing intrigue is already developing - a scientist reckoned that some of the soil around the airbag 'looks like mud, but it can't be mud'."
