    My understanding was that it wasn’t the presence of ‘water’ that was a big deal worthy of an actual full-blown press conference, but that not only had they confirmed the signature of H2O, but also that it was occurring to some degree in liquid phase, on the surface of this icy cold planet with the barely-worth-the-name atmosphere… the corollary being the old saw that “wherever water flows on Earth we find life.”
