Curiosity discovered high levels of manganese oxide minerals in rocks investigated at a location called Windjana during the spring of 2014.
Manganese-oxide minerals require abundant water and strongly oxidizing conditions to form.
Researchers found high levels of manganese oxides by using a laser-firing instrument on the rover. This hint of more oxygen in Mars early atmosphere adds to other Curiosity findings such as evidence about ancient lakes revealing how Earth-like our neighboring planet once was, NASA reported.
The newly announced results stem from results obtained from the rovers mast mounted ChemCam or Chemistry and Camera laser firing instrument. ChemCam operates by firing laser pulses and then observes the spectrum of resulting flashes of plasma to assess targets chemical makeup.
The only ways on Earth that we know how to make these manganese materials involve atmospheric oxygen or microbes, said Nina Lanza, a planetary scientist at Los Alamos National Laboratory in New Mexico, in a statement.
Now were seeing manganese oxides on Mars, and were wondering how the heck these could have formed?
The discovery is being published in a new paper in the American Geophysical Unions Geophysical Research Letters. Lanza is the lead author.

If Mars used to have liquid water on the surface, and atmospheric oxygen, What happened? Any theories on that?
Their Democrats came into power.
“WHAT DIFFERENCE AT THIS POINT DOES IT MATTER ANYWAY?!?!?!?!
One is that Mars suffered a cosmic collision. If you look at planet itself, the “texture” is different between the N-S hemispheres, leading to the theory that the South got hit really hard, geologically impacting the South, and cataclysmically destroying the atmosphere.
Maniacs! You blew it up! Ah, damn you! God damn you all to hell!
One theory is that Mars lost its magnetic field, so the atmosphere was eventually stripped away by solar radiation.
Most of the atmosphere was lost to space and water either evaporated or sublimated into the ground.
Today Mars is a dry, barren cold desert. At one time in its past it was a warm, wet world lush with water and life.
Well, yes there are. But they want trillions of more space dollars to find that out and conclusively determine something which will make no difference whatsoever on the state of things on this planet.
Planet X (orbiting where the asteroid belt is today) exploded, stripped away Mars atmosphere and water, and left the side”sprayed” on the planet.
...lush with water and life.
You’re sure about life? Like, dna-coded life?
.. and left a higher elevation on one side of the planet from material sprayed on the planet.

“I have always said, heard, that it would not be strange that there had been civilization on Mars, but maybe capitalism arrived there, imperialism arrived and finished off the planet,” Chavez said in speech to mark World Water Day.
Did it have a mag field?
The Pinkos certainly do have an upside down view on reality.
“Today Mars is a dry, barren cold desert. At one time in its past it was a warm, wet world lush with water and life.”
That does appear to be the narrative these days.
A lesson to all of us what will happen if we don’t enslave the masses to prevent AGW. /s
Hey Mars girls were shapely but “earth girls are easy.”
