Survival of Methanogenic Archaea from Siberian Permafrost under Simulated Martian Thermal Conditions
Since ESA mission Mars Express determined water on Mars, a fundamental requirement for life, as well as the presence of CH4 in the Martian atmosphere, which could only have originated from active volcanism or from biological sources, it is obviously that microbial life could still exist on Mars, for...
