Scientists have discovered on Mars underground riverbeds
Previously, more than once the scientific world raged about the fact that on Mars it will be difficult without water and the first thing was the mission to look for water. First, something in the form of dirt sprinkled with water found in a crater, and then the search yielded found the underground lake, but now that cooler. Martian probe Mars Express enlightened the entire surface of Mars and revealed the location of groundwater. The water there may be, but when in the distant past these underground channels flowed the rivers of water. Underground rivers on the planet in the past were connected to a single water system, it is a pity that now this system is free of water...
Find underground waterways scientists helped European probe Mars Express, the pictures showed the Grand underground canals and waterways. In some empty underground lakes, scientists have found minerals that to some extent confirm the existence of water in the past there and these minerals also according to astrobiologists could play an important role in the formation of life on the planet.
Now Mars is just a dry and almost anhydrous planet,but according to scientists, when in the past everything was completely different. When on the surface of the flowing river of their manifestation on the ground can still be seen. On the surface flowed not just thin streams, and abundant rivers, in many places the surface of Mars, scientists find minerals that could appear here only in the presence of water. Not all the water as it turns out evaporated from Mars, scientists from Europe last year with the help of the same unique probe found on Mars full of water underground lake.
Scientists actively exaggerate the topic of water, and sometimes even publish different articles. Here recently in the journal of Geophysical Research – Planets, the experts from Utrecht University in his article spoke about the fact that Mars in its early history, water was very much. Something like scientists and has previously been nominated, but it was mostly prodding a finger at the sky and arguments without evidence. Now everything is much more reasonable about the presence of water in the past, there is everything you need to think that in the distant past on Mars bloomed Apple trees. At some point, the water was on the surface in abundance, but then the climate became harsh and the water remained only under the surface at great depths. Scientists based on their research prove the presence on Mars of an extensive system of underground riverbeds. To prepare a scientific basis for their findings, scientists have studied 24 deep craters on the surface of the Planet. And as it turned out in the lower tiers of these deep craters were found signs that could only arise as a consequence of the presence of large masses of water. At the bottom of the craters is on the perimeter of the mark that in the craters when it was standing and possibly running water. The water gradually receded and eventually just went underground.
At the bottom of the five craters were found minerals that could possibly be associated with the presence of life on the planet. This and different varieties clay, carbonates and silicates. When it is possible on the planet`s surface in a water pool were components of organic. Once again, the scientific world has confirmed the previously born hypothesis about the past of Mars. Mars once upon a time was probably not so dry and not so cold and perhaps even on the surface was inhabited by living organisms.
