In relation to the video published yesterday by INAF (see https://www.facebook.com/PianetaMarte.MdM/posts/2136248119791703?__tn__=-R) and related ESA article (see http://www.esa.int/Our_Activities/Space_Science/Mars_Express/Mars_Express_matches_methane_spike_measured_by_Curiosity), in which it is not only mentioned the episodic emission of methane but also its abnormal sudden disappearance, I would like to propose you the reading of this interview to a famous Italian astrobiologist that I made about three years ago on behalf of my former collaborator page.
I think that some of my considerations are definitely confirmed by the INAF video; what do you think?
