There is also the detection of seasonal production of methane on
Mars. An interesting fact that I haven't seen discussed about the Mars
methane is that even the proposed non-biological sources for it would
suggest that *liquid* water exists near the surface of Mars. A nice
summary of the methane results and the proposed explanations is he

3.4 Methane.

The non-biological processes include volcanic processes, including
geothermal, and geochemical processes. The volcanic processes with the
abundance now apparent of subsurface ice on Mars suggest liquid water
would exist near surface. And the suggested geochemical processes all
require *liquid* water to work.
Gil Levin has collected articles on the Mars life question, including
discussion of the Mars methane, he
