Ancient Mars did not have atmospheric oxygen, claims new research

That does not mean the planet did not have life.

A new experimental study conducted by Washington University in St. Louis is defeating any hope that scientists have had that atmospheric oxygen once existed on the Red Planet, according to a press release by the institution published on Thursday.

Instead, the scientists have found that under Mars-like conditions, manganese oxides can be readily formed without any presence of atmospheric oxygen.

The new research is indicating that just because NASA’s Mars rovers found manganese oxides on Mars in 2014 does not mean that oxygen was actually present in the planet’s atmosphere.
