No hint of Mars microbes NASA reported that its Mars rover, Curiosity, which has been trundling across the red planet for a little more than a year, has deflated hopes that life could be thriving on Mars today. The conclusion, published in the journal Science, comes from the fact that Curiosity has been looking for methane, a gas that is considered a possible calling card of microbes, and has so far found none of it. While the absence of methane does not entirely preclude the possibility of present-day life on Mars — there are plenty of microbes, on Earth at least, that do not produce methane — it does return the idea to the realm of pure speculation without any hopeful data to back it up.
