It's only a matter of time now...
An instrument on the six-wheeled robot identified mysterious spikes of methane that cannot easily be explained by geology or organic material transported to the planet by comets or asteroids. While scientists cannot be sure what is producing the methane, they acknowledge the source could be bacteria-like organisms. If the existence of living, breathing microbes on Mars is confirmed, it will be one of the most monumental discoveries in history. Previous satellite observations have detected unusual plumes of methane on the planet, but none as extraordinary as the sudden "venting" measured at Gale Crater, where evidence suggests water once flowed billions of years ago.... The Nasa authors are cautious about jumping to conclusions, but conclude that "methanogenesis" - the formation of methane by microbial bugs known as methanogens - may be one answer to the riddle. They wrote: "Our measurements spanning a full Mars year indicate that trace quantities of methane are being generated on Mars by more than one mechanism or a combination of proposed mechanisms - including methanogenesis either today or released from past reservoirs, or both." independent...continues ------------------------- Specializing in sarcasm and condescending rhetoric since 1971. |
