What if we found out that there was so much water on Mars before 4 for billions of years that it would cover almost half the northern hemisphere?

How indirectly did the National Geographic server: we seem to have found it.

Research conducted by experts from NASA's Goddard Space Flight Center using two telescopes in Hawaii and Chile. The research was conducted by NASA scientists who measured traces of atomic elements of water in the Maru atmosphere using powerful telescopes here on Earth.

Scientists have estimated that currently the ocean on the Red Planet would contain more than 12,4 million cubic kilometers of water and would probably be located in the northern hemisphere. According to scientists, the ocean on Mars existed during the wet Noachian (?) Period, which ended about 3,7 billion years ago, the time when (again, according to scientists), life began on Earth. Since then, it has been said that 87% of water is the key to starting the formation of new life on other wages. This water has disappeared on Mars.

Lead Researcher Dr. Geronimo Villanueva said in an interview: "Our study provides solid estimates of how much water he had in the past based on how much water was lost in space. Thanks to this work, we can better understand the history of the presence of water on Mars. "

Further research revealed that the study had lost 6,5 times more water over the years than is currently trapped in its polar ice caps. Estimates suggest that the ancient ocean would cover about 19% of the planet's current surface.

If you want to get a better idea of ​​how much water you are dealing with, then compare that the Atlantic Ocean on Earth occupies 17% of the surface.

Smiley on Mars - A random or artistic spell?

From the scientists' opinion, it is conceivable that they finally admitted that water had to be on Mars. Unfortunately, as part of maintaining the status quo, the water had to disappear before Mars could begin to create anything that we humans would call life. So the scientific community once again took a little step forward somewhere already to the unbelievers clear long ago ... :)

You obviously still have a long way to go to discover the next round. We'll see how long it takes to find any fossils or living organisms (including plants). It will also be interesting how you explain that NASA has retouched water bodies from several photographs. (It doesn't have to be directly about H₂O).
