The atmosphere of Mars regularly surprises researchers. Previously, jumps in methane concentration were recorded, and recently there was a similar anomaly with oxygen. What are the reasons for the following changes, experts cannot say for sure.
An increase in oxygen concentration was noticed by the Curiosity rover in the area of Mount Sharp. The robot has a built-in laboratory for soil and gas analysis.
The atmosphere of the Red Planet is 95% carbon dioxide, oxygen in it is only 0.16%. Freezing carbon dioxide changes pressure, which in turn displaces other gases to establish a new balance. Once again, all gases behaved predictably, except oxygen.
Usually in spring and summer, the concentration reaches 30% and decreases by autumn. But this time there was no decrease.
The amount of oxygen on Mars is increasing every year. Where it comes from is a mystery to everyone. Splitting water is excluded, since there is very little of it on the planet.
What is Mars hiding and when will we understand all its secrets?
