Mysterious oxygen fluctuations on Mars detected by Curiosity Mars Rover

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars.


As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.

The video below shows and explains the strange oxygen fluctuations on Mars.
