Earth's oldest organisms can survive on Mars: Study

Technology Desk: Earth's oldest and simplest organisms called methanogens, are capable to survive on Mars, according to a new study.

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.
