Bottom line is that methane outgassing has been found in the same areas as water vapor outgassing. Signs of this had been hinted at before, but the levels etc. are causing a big rethink as to why.
The speculation in the science/space press is that this is either evidence of volcanism or subsurface lifeforms giving off methane as part of their metabolism (or both for that matter).
Should be interesting either way.
Should be on NASA TV, so I'm setting the DVR.
