There was a lot of water on Mars. Astronomers believe this. But maybe we should say: there is always a lot of water on the Red Planet. This is because, according to new data, the water that flowed abundantly on Mars billions of years ago is trapped in the surface of the planet.
Mars appears to us today as a desert world. ButIt is estimated that water flowed abundantly on the red planet billions of years ago. So much so that the entire planet may have been covered by an ocean at a depth of about 100 to 1,500 meters. Equal to half of our Atlantic Ocean. To explain this water disappearance, researchers generally blame the weak Reigns on Mars. It would have simply allowed water to escape into space.
However, new data show that this is the case “Atmospheric Leak” Most of the water that has disappeared from does not count . In contrast, they suggest that the Red Planet still has 30 to 99% of the water that has flowed in the past. Trapped Mars Christine.
To achieve this conclusion, the (Caltech, United States) Cross-reference data collected by many From . They compared them with observations And laboratory tasks . Their idea: to study the amount of water on Mars, regardless of its shape (steam, Or ) Composition over time and chemistry And the crust of the Red Planet.
Lack of recycling
However, the hydrogen ratio of deuterium measured by astronomers and the hypothesis that a large amount of water flowed on Mars in the past do not apply. Moreover, according to the researchers, the current state of Mars can only be explained by considering that water is trapped in the minerals on its surface.
On earth, too, water is trapped by rocks. In form ‘ Constantly melting And creates a new overlay on the edges , Recycled water – and other – In the atmosphere . On Mars, on the other hand, there are no tectonic plates “Drying” Surface. Researchers are now eagerly awaiting the information provided to them , The From NASA, which landed on Mars a month ago.Or other hydrating minerals. But the old woman
