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'."

"I am curious though as to why they dont think it could be mud if they are indeed suspicious of water being present?"

Nasa doesn't like to operate that way. They don't want to finger a suspect and look at only proof that it's what they're after. Instead, they want to look at all the data and try to learn everything they can.

Seems to me they're just avoiding being overly zealous in their approach. In the process of proving something does exist, you risk avoiding the evidence that it doesn't.

Actually it would probably boil first. Freezing is a much slower process. The lack of atmospheric pressure would get to it long before the temperature ever did.

You actually think NASA should sit on anything from Spirit until it has been published in Nature? Can you imagine the public outcry? Spirit lands, and they don't say anything except "Look at the pretty pictures! No, we won't tell you what we've found. Yes it is moving around and everything's working fine, but we won't tell you anything until publication. You'll just have to wait." The public would go apeshit. The people on /. would be out for blood. With a program this big, they can't sit on everything they find, it's just a fact of modern life. They are doing their best by keeping everything low key. Lots of "maybes" and "appears-to-bes" and "looks likes"

Even once it has been released into the peer reviewed world, it will be sensationalized. How many times has there been a panacea cure for cancer published in Science? If you read the NYT, you'd say dozens. If you read Science, you'd say never.
