Terraform Mars




First we must start from the basis that there is no life present on Mars, because we still cannot affirm that life exists or does not exist on Mars, we would need to examine what is under the surface of the red planet, where we have recently known that there are large reserves of liquid water, large ocean-sized reserves, which is quite normal, it is within the logic, keep in mind that if Mars had water in the past, which we know well, it must have had a large ocean in the northern hemisphere and then lakes, seas, rivers, etc. that water also filters into the interior of the planet.


The seas are not isolated and closed bathtubs, they filter the water that we see, the water that we see from a sea, the Mediterranean is only a small part of the whole water that is also below that has been filtered, beneath the surface of the Earth there are large reserves of water and that also happens on Mars, on Mars those oceans, those lakes were lost a long time ago, but the water that remained below the surface is there and much of that water is in a liquid state because the interior of Mars is still hot, it is not as hot as the core from Earth because Mars is a smaller planet, but it still keeps a lot of heat.




If life emerged on Mars billions of years ago, something that we still cannot deny or affirm, it did arise, because also in that same period where Mars had water and the essential components for life to form was the same moment in which life emerged on Earth, it is very possible that these microorganisms and emerged colonized the underground aquifers just as happens on our planet and that they stayed there evolving, without needing to come to the surface, so it is a possibility still open, but we are going to work with the idea that There is no life present on Mars, because if it existed, even if it is down there, several kilometers deep, it could be a pretty big problem and I am not talking right now about moral ethics, about these things about planetary genocide and these stories, no, I am talking about how we, our microorganisms can contaminate those living beings, Martian microorganisms, but those Martian microorganisms can also contaminate us, after all they are on their planet and if they exist and have evolved down there, they have evolved for billions of years. in extreme conditions, so they do exist and some of them end up filtering into one of those colonies like the ones Elon wants to create. More may find that suddenly he is in a bacchanal in a paradise for him to expand and do what a microorganism does, reproduce and eat.

Two questions must be answered, is this terraforming of other worlds a thing of science fiction or is it really something that scientists think about as a real possibility? Yes, they think about it quite a bit and sometimes in a somewhat impressive way, like the scientific proposal from February of this year called “inoculating Enceladus”. Enceladus is a small moon of Saturn, it is approximately 500 km in diameter. ice, water cannot be maintained in a liquid state outside of that icy crust that is protecting it, but beneath the icy crust of Enceladus, there is liquid water in abundance and elements that can be basic for life to form.


And in this study they raised the possibility of colonizing with terrestrial microorganisms, bacteria and tardigrades, why not, in a cage to see how they reproduce, how they expand and if it is possible for an ecosystem to be created in this type of world, with oceans under an icy crust above them, that is, without seeing sunlight.


The second issue is that we must also take into account that terraforming other worlds can help us to correctly manage our own, the first planet that we must learn to terraform is the Earth, we must transform those regions that we have damaged with pollution and other evils, that is the initial step, how are we going to be able to give life to another planet like Mars or any other star if we are not able to recover the life of our own? It would be useless, don't you think.


In the end, who knows, if Mars is already inoculated with the bacteria and organisms that have been accidentally sent on different missions to the red planet, only time will tell.
