NASA’s Curiosity rover has failed to detect any methane on Mars over the past year, which means it is unlikely life exists there now. Researchers had been intrigued by the possibility of methane on Mars after research a few years ago by Michael Mumma of Goddard indicated it was present. The results do not definitively conclude there is no life on Mars as methane could exist above where Curiosity sampled, or life could exist underground. Curiosity will continue searching. The rover is likely to get new software next year that will allow it to measure for methane with a greater degree of reliability than it does currently. (Image Credit: NASA)
