Introduction: The spectroscopic detection of methane in the atmosphere of Mars is the first observation of an organic compound on that planet [1-3]. CH4 has a lifetime of a few centuries, which suggests a young or current source. On the other hand, this lifetime is long enough for the atmospheric circulation to yield a uniform distribution of CH4 across the planet, which is not what is observed. Indeed an intriguing aspect of Martian methane is that it appears to vary with time and location… CONTINUE READING
