A latest study reveals, salty water just below the surface of Mars could hold enough oxygen to support the kind of microbial life that emerged and flourished on Earth billions of years ago.
Researchers report, in some locations the amount of oxygen available could even keep alive a primitive, multicellular animal.
Up to now, it was not thought that oxygen could play a role for life on Mars, due to its rarity in the atmosphere, being just about 0.14 percent.
The new study began, when NASA’s Curiosity Mars Rover discovered manganese oxides, which are chemical compounds that can only be produced with a lot of oxygen.
Lead author of the report, Vlada Stamenkovic who is a Theoretical Physicist at the Jet Propulsion Laboratory in California says, the results do not imply that there is life on Mars, but they show that Martian habitability is affected by the potential of dissolved oxygen.
