An article from The Independent (http://news.independent.co.uk/world/science_medical/story.jsp?story=505454) says signs of methane are detectable in Mars' atmosphere.
Especially interesting in that it claims methane must be replenished, and therefore this may prove recent existence of (possibly microbial) life.
Cheers. Newt.

Comets contain methane, and maybe methane can be produced from the carbon in carbonaceous meteorites. Both comets and meteorites impace Mars.

What would be the likely annual source of methane from these sources?
