“Beaches, of abandoned bodies, of stolen moments, while the skin burns …”. No, not only the beaches of Renato Zero, and there are no abandoned bodies, but there may have been life at the level of microbes on the Martian beaches. Above all, there could be an ocean, as can be seen from the data obtained from the Chinese rover Zhurong which resulted in traces of sandy beaches 10 meters deep (the radar of which it was equipped could probe up to 80 meters), identifying a coast.
As always in science, the data are shared with everyone to make them analyze (do not trust studies that do not share their data), and scientists from the University of California in Berkeley have published an article in the Pnas magazine of the National Academy of American Sciences to hypothesize the existence of ancient organisms.
Mari, Oceani, but also rivers (as once on Venus, before it became unlivable). Of course, more than microbes it will be difficult to find them, because we are always talking about the Martian oceans (although most of the life on Earth was precisely made up of microorganisms for more than three billion years). Mars in fact he immediately lost the magnetic field (a shield against cosmic and solar radiation), as well as theatmosphere (another shield), which is why it is the desert it is. Not quite a nice place to go on vacation, but to think these remote beaches makes us think of making Mars make a save raft for a distant future again (it will not concern me, neither you, nor your children, nor your grandchildren, it will be for this reason that few interest the Marzian colonization projects).
The red planet is the most habitable of the planets of our Solar System (imagine the others), but so much lethal That it is difficult to imagine the reasons for this fixation of moving humanity there, for example by exploding atomics to the poles to defrost the water ice and recreate the oceans, when you should still live underground and shielded. More than terraforming Mars is easier than in the meantime, in the next hundreds of years, we will have managed to Mars the earth.
Almost, because the earth will still have its magnetic field and its atmosphere as spatial shields. In short, for humanity there will be some problems, but for most of the other species nobody for a long time. As George Carlin says in one of his famous monologues: “The planet is fine, People Are Fucked”.
