I"d like to apply for this job http://eporner.in.net/ eporner Olivier Witassen a scientist from the Mars Express Project, discusses this fascinating possibility: “In 2004, right at the beginning of the mission, Mars Express showed that there was methane in the atmosphere in very small quantities. There are still discussions about the veracity of these observations, but if methane is there it has to be explained – because in the atmosphere, methane is destroyed. Therefore you need a methane source permanently emitting this gas. There are lots of discussions about what the source of this methane is. It could be geological activity, reactions between underground rocks and liquid water so creating the methane. This would mean Mars is geologically active. Or it could be biological activity generating this methane.”
