There was a lot of water on Mars. Astronomers are convinced of this. But perhaps we should say this: There is always a lot of water on the red planet. Because, according to new data, billions of years ago, abundant water from Mars is trapped in the planet’s crust.
Mars today appears to us as a desert world. But, heIt is estimated that water flowed in abundance on the red planet billions of years ago. So much so that the entire planet could be covered by about 100 to 1,500 meters of deep sea. Equivalent to half of our Atlantic Ocean. And to explain the disappearance of this water, researchers usually blame the weak Who rules Mars. It only allowed water to escape into space.
However, new data suggests that this phenomenon “Atmospheric leakage” Disappeared from the water that is mostly unaccounted for. Conversely, they suggest that there is still between 30 and 99% of the water flowing in the past on the red planet. trapped in Mangal’s crust.
To come to this conclusion,(Caltech, United States) Cross-referenced data collected by many From . He also compared them to observations And laboratory work . His idea: to study the amount of water on Mars, regardless of its form (vapor), or ) Chemical composition over time And the crust of the red planet.
Lack of recycling
This is more accurately the deuterium ratioWho put a chip in their ears. Remember that deuterium is a heavy form of hydrogen. Therefore the tendency of a planet to escape from the atmosphere is less due to lack of gravity as compared to hydrogen. In fact, if a planet loses water Via Its upper atmosphere leaves a telltale sign on the process report On the hydrogen of the said atmosphere. It will focus more and more on deuterium “Simple”, Or 0.02%.
However, the hydrogen ratio measured by astronomers and by the Hypothesis is not consistent with the large amount of water flowing into Mars in the past. And, according to researchers, the current state of Mars can only be explained by considering that water is trapped in the minerals in its crust.
Even on earth, water is trapped by rocks. In the form of’Or other hydrated minerals. But old lady Melts continuously And creates a new layer on the edges of , Water recycling – and others – in the environment . On the other hand, no tectonic plates imbalance on Mars “Drying up” Of the surface. Researchers are now eagerly awaiting the information that will be provided to them , To From NASA which landed on Mars a month ago.
