There are a lot of caveats and unknowns with this research — after all, the existence of these briny subsurface lakes hasn’t yet been proven.
The likelihood of life on Mars has been an enticing probability for quite a long time, and ongoing revelations have just expanded energy about whether we’ll discover life on the red planet. Presently, another investigation in Nature Geoscience sets that it’s conceivable that Mars may have enough oxygen to harbor life under its surface.
The group was driven by Vlada Stamenković from NASA’s Jet Propulsion Laboratory (JPL), and their discoveries originated from two unique revelations. We know there’s a plausibility that there are subsurface lakes of briny water on Mars; one specifically might be situated under the Martian polar ice top. This implies there’s a great deal of potential for oxygen inside these lakes, on the off chance that they exist.
In 2016, the Mars Curiosity wanderer found that Mars may once have had an oxygen-rich climate, yet the loss of its attractive field implied that the greater part of its surface oxygen got away. In any case, there is still oxygen inside the planet’s stones which implies that it might be available underneath the surface of the planet.
Given both these revelations, the JPL-drove group investigated how much oxygen could exist in these subsurface briny lakes, and whether it is sufficient to help life. The group found that it was undoubtedly conceivable, particularly in the polar districts in light of the fact that the lower temperatures in these areas imply that it’s simpler for oxygen to enter these briny lakes.
Yet, it’s the subsequent stage forward in indicating how life could exist on the red planet, given what we contemplate Mars. In addition, it additionally demonstrates to us how life could exist on different planets without photosynthesis.
