In a new article in the journal Nature Communications, researchers detail their findings of methane in 6 Martian meteorites.
According to the authors, "The occurrence of methane in Martian rock samples adds strong weight to models whereby any life on Mars is/was likely to be resident in a subsurface habitat, where methane could be a source of energy and carbon for microbial activity."
The Curiosity Mars Rover recently detected methane in the Martian atmosphere, as well as organic molecules in Martian rocks.
