CAPE CANAVERAL, Fla. — Initial analysis of the atmosphere of Mars from NASA’s rover Curiosity has shown no sign of methane, a gas detected previously by remote sensors, researchers said on Friday.

On Earth, more than 90 percent of the methane in the atmosphere results from living organisms and its presence in the Martian atmosphere, first detected in 2003, raised the prospect of microbial life on the planet.
