Several astromóviles look for the traces of a life that could have existed millions of years ago. What happens to the red planet.
A recent NASA study He showed, thanks to Astromóvilesthat the planet Mars is condemned to be desert despite the existence of rivers in the same
It could be found on its surface traces of ancient lakes, which indicates that the water once flowed. It is considered that Mars has all the ingredients for life with the exception of liquid water, which for astronomers could be the most important and the reason for this.
He Curiosity RiverAstromóvil, sent by NASA to Mars to investigate its geology and atmosphere, found this 2025 a missing piece that could explain this event: Rich stones in carbonate minerals. These minerals are a kind of carbon dioxide sponges, captured in the atmosphere and trapped in the rock.
Edwin Kitescientist at the University of Chicago and member of the Curiosity team, was the main author of the studysaid there was “Habitability flashes” In some moments and places of Mars, but these stones seemed to be the exception.

Why there is no life on Mars, according to experts
In the LandTo begin with, carbon dioxide in the atmosphere warms the planet already over long periods of time, carbon is caught in carbonated rocks. After this, volcanic eruptions throw the gas back to the atmosphere creating a cycle balanced climatic that encourages the constant existence of water.
Instead, “On Mars, it has a weak volcanic emission rate compared to Earth”Kite confirmed. Which generates that Red planet is much colder and less habitable.
The brief periods of liquid water on Mars were followed by 100 million years of sterile desert, which would be too much time for something to survive. “It is still possible that there are liquid water bags in the subsoil of Mars that has not yet been found”added the scientist.
If it is determined that Mars never had microorganisms during his periods with water, it would be an indication that it is difficult for life to arise on other planets. If the opposite occurs, “basically it would tell us that the origin of life is easy at planetary scale,” Kite said.
