Has the Mars Rover Sniffed Methane?
First time accepted submitter GrimAndBearIt writes "NASA's Curiosity rover is poised to settle years of debate on the question of atmospheric methane on Mars, which would be a sign of microbial life. With parts per trillion sensitivity, it's not so much a question of whether the rover will be able to smell trace amounts of methane, but rather a question of how much. NASA has announced that Grotzinger's team will discuss atmospheric measurements at a briefing on 2 November. If the rover has detected methane at sufficiently high concentration, or exhibiting temporal variations of the kind that suggests microbial activity, then it will surely motivate a desire to identify and map the sources."

Even if there is temporal variation, why are they so certain that the methane in the air is due biological activities?
They are not, in fact scientists have been really busy trying to come up with alternate explanations for the presence of methane on Mars. However, the indications that the methane may be due to life are strong enough to make this worth investigating even though the odds are probably rather slim.
