Mars is the passion of the scientific-space community, It seems clear that humans will return to the Moon via NASA’s Artemis mission, but exploration of the Red Planet’s mysteries is even more promising for scientists working to answer the million dollar question : Was there life on the surface of Mars?
A report published on the Ámbito website cites a study conducted by the US space agency discovered that Mars had habitable zones at the same time when life originated on Earth, Does it respond to the fact that there was life on the second smallest planet in the Solar System?
Ancient river deltas, dry lakes, craters and volcanoes, features similar to those of our planet and which indicate that Mars had an active and perhaps livable past. But confirming that there was life is much more complicated than uncovering the current evidence.
work of the persistence rover
In November 2022, the Perseverance rover landed in the Jezero Crater, formed 4 billion years ago as a result of an impact on Mars.
Reports suggest that this crater would have contained a lake into which a river channel flowed, which, among other things, left a fan-shaped delta and scars that suggested there was a continuous flow of water, which is an ideal The place was investigation.
The rover also analyzed the rocks, which confirmed that secondary minerals formed by water passage over the rocks may be present. In addition, carbonates, gypsum, and clays formed in the crater in a similar fashion as on Earth and at a time when life was emerging on our planet. coincidence?
So… what was life?
This is a question that scientists have not yet been able to answer. The hopes are high, but much remains to be discovered. Persistence samples have not yet arrived on Earth for further investigation.
Assuming that life existed on Mars, it died out more than 3 billion years ago. The harsh Martian climate is probably the main reason for the extinction of living organisms. Could science confirm that there was no life, it might tell us more about the origins of our species.
