Check this out...I was reading about potential Mars water on Slashdot and read this amazingly concise, informative post.....then looked up to see the name of the poster! It even has his signature disclaimer "We will probably not know for sure until it is released and we get our hands on one" type conclusive sentence! There be something in that name....

NASA did not "find water" years ago... or ever! They found the gamma-ray spectrometry signature for hydrogen and proposed this was likely locked up in ice. Now a different means has been used to measure the subsurface (much more effectively in terms of depth, if less conclusively in terms of composition) and also found results not inconsistent with ice. We will probably not 'find ice' until someone goes there and drills. Until then, different means of measurement are a good idea (even though the media, and worse the bottom-feeding pseudo-journalism of sites like Slashdot, will misinterpret the conclusions that can be drawn).
