Rover sniffs for sign of life
LOS ANGELES- The Mars Rover Curiosity sniffed the atmosphere and found no methane gas, which on earth is linked to living things, released when animals digest.
That's the conclusion from a new study released in the journal Science. Scientists now say its bad news for the search for microbial life underground on Mars.
Curiosity sampled the air for eight-months but came up empty in the search for methane. It contradicts what previous observations found from orbiting spacecraft and telescopes on earth that found plumes of methane on Mars.
The rover is now headed toward a mountain and will continue to sniff and hunt for methane on its journey.
