Curiosity, the exploration vehicle of the American Aeronautics and Space Administration (NASA) on the planet Mars, determined that there is no methane gas on the Red Planet.
Scientists described the absence of methane gas as "bad news" for microbial life research on Mars.
Methane gas on Earth is largely produced by living organisms.
In previous observations made through telescopes on Earth, it was suggested that there was methane gas on Mars, and the hope that life could exist on the planet arose.
The data obtained by Curiosity was published in the journal "Science".
Curiosity was launched into space on November 26, 2011, and landed in Gale Crater on the Red Planet on August 6, 2012.
Curiosity, the most advanced robot ever built as part of a possible trip to Mars, is trying to find the chemical basic building blocks of life on the Red Planet with its more than 12 cameras, a weather station, drilling and tools that allow it to study the environment.
