A report published by the National Aeronautics and Space Administration (NASA, for its acronym in English) announced that the planet Mars had habitable regions at the same time life originated on Earth.
Ancient river deltas, dry lake beds, craters, volcanoes, and features similar to our planet are found on Mars.
However, confirming that there was life is much more complicated than highlighting the current evidence.
The work of the Perseverance Rover:
In November 2022, the Rover Perseverance landed in the Jezero crater, generated 4,000 million years ago, as a product of an impact on Mars.
The report indicates that this crater would have housed a lake into which a fluvial channel flowed, which, among other things, left a fan-shaped delta and traces that revealed that there was a constant current of water, that is, the perfect place to investigate. evidences.
The Rover also analyzed rocks that confirmed that secondary minerals could have existed, formed by the passage of water over the stones.
In addition, the formation of carbonates, gypsum and clay in the crater occurred in the same way as on Earth and at a time when life was emerging on our planet.
Scientists say that, assuming that life existed on Mars, it became extinct more than 3,000 million years ago.
The fierce Martian climate is probably the main reason for the disappearance of living organisms. Should science confirm that there was no life, this could give us more information about the origin of our race.
