• Resolving Mars methane isotopes, as bio probe?

    From stargene@21:1/5 to All on Mon Jul 1 21:22:53 2019
    The subject of Martian methane blowouts keeps arising. Assuming
    that they will be confirmed, is there any way yet on-site or in-orbit,
    to then measure the carbon and oxygen ISOTOPE ratios? These
    would give some sense of whether methane sources are geo-
    chemical or biological, since organisms tend to sequester lower
    mass isotopes of the same element.
