As a new study surfaces, we learn how surface waters on ancient Mars might make it habitable for microbial life. Currently, our planet is the only known region where life is possible in the Universe. Life, as we know it, can occur in many shapes from the omnipresent micro-organisms that populate almost every square inch of our planet to the cell-phone-toting organisms like us.
Most likely, it would take some time until we can witness a possible identifying or examination of life beyond our solar system. The Red Planet is the most hunted for such a thing. First, it is somehow close to us compared to the moons of Jupiter or Saturn. Also, Mars can be easily noticed due to its lack of dense atmospheres, such as Venus, for example. So there are enough pieces of evidence that the planet’s ground temperature and pressure waves around the part when liquid water can exist.
The water on Mars could have sustained life
Researchers became more and more sure that Mars was habitable billions of years ago. They are currently trying to find out all the types of water chemistry that could have made the minerals noticed on Mars now, which were generated a very long time ago. pH, Salinity, and the redox state are significant features of natural waters. For example, Earth’s actual atmosphere is highly oxygenated. Still, one requires only to dig a few inches into the floor of a lake or beach to discover conditions that are highly decreased.
The latest examinations on Mars, however, indicate its old conditions might offer hints about its previous habitability. Definitely, the features of pore water withing sediments stored in Gale Crater in Mars show those deposits appeared only when liquid water was present. Earth’s oceans are indeed hosted to multiple structures of life. Thus it looks compelling that Mars’ previous ground environment was a site equal Earth life could have developed. It is still a mystery, though, why proof of life on Mars is so challenging to discover.
