Water source of life, limited resource
Water is one of the most abundant chemical compounds in the universe, being a need for human life for all known life forms and a limited resource, whose demands are rapidly increasing.
The water molecule is very simple that can be found in many parts of the solar system itself according to NASA, whose missions seek to explore and find new worlds in which water is. Water is just a part of its search for habitable planets and life far beyond the earth, therefore scientists are looking for liquid water in the most attractive places to find an answer to the question if life exists beyond the planetin which we live.
The possible answer to this question is that water as it is a geologically intriguing resort and substanceenergy is a probable life indication because it increases the possibility of being an inhabited planet. Compared and based on the unique example of the earth is that life tends to appear wherever there is water, that is why the search for NASA’s life beyond the earth has been driven by the mantra ‘continues the water’. An example of research in this regard is the appearance and discovery of ice on the moon and Mars, which could supply future human explorers. On the other hand, part of the water on Earth probably came from comets that crashed into the planet.
NASA’s spacecraft have also found signs of water in permanently shaded craters in Mercury and the Moon, which maintain a record of ice cream over the centuries as cryogenic memories.
Currently, the Earth is the only known planet that has consistent and stable bodies of liquid water on its surface. Finding liquid water beyond our solar system can indicate the existence of extraterrestrial life, according to the data collected by the NASA Kepler spacecraft and the W.M. Keck Observatory scientists have determined that 22 % of solar stars in our galaxy have land size planets in their habitable zone and could house life.
Finally NASA has achieved that the search for extraterrestrial life is a high priority, and recent discoveries have mainly pointed Mars as a promising hope of life, so they give a great reason for the optimism that the effort will succeed very soon. However, none of the observations guarantees that there is life or that it once existed in Mars or some other planet, but the presence of water increases its probability and its flows could lead to various space agencies to other sites where you could find an indication oflife and different landing places for future missions with the objective of collection of material.
