Methane? Methane!! Yes, this could be a v interesting update/briefing. Michael Mumma and his team are confident that they have measured local methane plumes of up to 60 parts per billion over Nili Fossae and the S.E. quadrant of the nearby Syrtis Major shield volcano. ................................ The big question still to answer - do they come from geochemical processes, biological processes or both? I - for one - am dying to find out!!!! I posted this in topic Local Methane Plumes On Mars a few months ago. In particular, check the interesting replies........ The problems on interpreting gases in the Martian atmosphere at parts per billion using ground based spectroscopy, alternative explanations for methane production such as via a Sabatier type process (good basic reference in Wikipedia) and Mars Express results. For a start, I wonder if the update will be based on data derived from ground based spectroscopy???!!! |
