Earth’s oldest organisms can survive on Mars: Study

According to a new study, Earth’s oldest and simplest organisms called methanogens, are capable to survive on Mars.

The recent research conducted at the University of Arkansas has suggested that these organisms are anaerobic, so they don’t require oxygen, organic nutrients, and are non-photosynthetic, indicating that they can even exist in sub-surface environments therefore, are ideal candidates for living on Mars.

Rebecca Mickol, a doctoral student in space and planetary sciences, found that in the laboratory, four species of methanogens survived low-pressure conditions that simulated a subsurface liquid aquifer on Mars.

The four species of methanogens Mickol studied were: Methanothermobacter wolfeii, Methanosarcina barkeri, Methanobacterium formicicum, Methanococcus maripaludis.
