The planet Mars and the fact that there is life or the movement of humans to live on the surface of the neighboring red planet
In the past few years, news has spread indicating that there is life on Mars and that there are indeed people who have been chosen to live on Mars.
Information and facts about the red planet:
Mars is the fourth planet in the solar system, and it is the planet that follows Earth directly in order, but the planet Earth exceeds it in size by almost double, and Mars is the seventh planet in the solar system in terms of size, or more precisely, Mars is the second smallest planet of the planets of the solar system after the planet Mercury.
* The planet Mars is called the red planet, in relation to the rusty iron spread on its surface, and the day on Earth is slightly shorter than the day on Mars.
A year on Mars is almost twice as long as a year on Earth, where one year on Mars is equal to 687 days.
* Mars has two moons, Phobos and Deimos, as scientists have called them.
* The distance between Earth and Mars, the distance between Earth and Mars at the farthest point between them is about more than 400 million square kilometers, while the least distance between Earth and Mars was in 2003 when they got very close to each other and the distance was estimated at about 55 million kilometres. A terrible meter, and the distance between Earth and Mars is uneven because of their rotation around the sun at different speeds.
* The planet Mars can be seen clearly from the surface of the earth, and the atmosphere of the planet Mars is very thin and not as dense as the planet Earth, which makes it unable to maintain its temperature. The temperature of Mars at the equator in the summer was estimated at 20 degrees Celsius, while the temperature was estimated At the poles B more than -150 ° C.
* The planet Mars contains the highest mountain peak in our solar system, which is the summit of Olympus Mons, with a height of more than 21 thousand meters, which is three times higher than the highest mountain peak on the planet, Everest.

Scientists and researchers, headed by the chief scientist at NASA James Green and the director of the Russian Space Research Institute and other senior space scientists, China, India and some Arab space scientists agreed to meet on the sidelines of the International Space Summit in Cyprus, where the Swedish Space Institute Professor Hermann Opgnorth said He said (If a person goes to another planet in our solar system, it will be to Mars). Scientists confirmed that Mars in the past was suitable for living, but something happened that caused the red planet to lose its atmosphere by up to 80%, as well as the magnetic field, the ocean and liquid water.
Water on Mars:
Researchers have discovered for the first time the existence of a huge underground liquid water lake on Mars, after decades of searching for water, the secret of life on the Red Planet, but the question still remains whether there is a possibility of life on the surface or under the surface of Earth's closest neighbors.
The team of researchers, headed by Roberto Orossi of the Italian National Institute of Astrophysics in the city of Bologna, said that the lake is about 20 km wide and is located at a depth of about 1.5 km under the ice of the red planet's south pole.
The team added that scientists have been searching for decades for liquid water on the surface of the planet adjacent to Earth, where water is a prerequisite for the existence of life as we know it, but the Mars Express probe of the European Space Agency was unable to read signs of life in the Martian lake.
The red planet, the planet Mars
This observation ends decades of controversy about the presence of liquid water on the surface of Mars, as confirmed by the American Association for the Support of Science (AAAS), which publishes the magazine "Science", and indicates the presence of dried river courses and the presence of sediments that show that there must have been liquid water on Mars before Billions of years when the weather was warmer then and the atmosphere on Mars was denser than it is now.
Water is found on the surface of Mars in the form of mostly ice. The two ice caps at the north and south poles of the planet represent most of the ice on the surface. There is also some ice in the rocks of the Martian crust. There are also small percentages of water vapor in the planet's atmosphere. On September 29, 2015, NASA announced Space officially reported the presence of salty liquid water flowing on its surface.
The presence of water in the form of ice is due to the climatic conditions of Mars, where very low temperatures lead to instant water freezing. However, studies have confirmed that the situation on the surface of Mars was very different from what it is now, and perhaps it was similar to Earth, where there was liquid water. In large areas of the planet's surface, the problem of oceans, such as the oceans that are now on Earth's surface.
There is a lot of direct and indirect evidence for this theory, including spectral analyzes of the surface of the soil of Mars, as well as the two polar ice caps, as well as the presence of many minerals in the crust of Mars, whose presence on the surface of the Earth is associated with the presence of water, including iron oxide, sulfur oxide, goethite, and silica compounds.
Unmanned space vehicles and flights to Mars have helped a lot in studying the planet's surface and analyzing its soil and atmosphere. One of the vehicles that helped the most in this was the "Mars Orbiter" vehicle to photograph the surface of Mars with high accuracy and analyze the surface of the planet thanks to the presence of a high-quality HiRise camera. It also revealed craters Corroding volcanoes, dry riverbeds and glaciers.
Spectral studies by gamma rays revealed the presence of ice under the surface of the soil of Mars as well, and radar studies revealed the presence of pure ice in formations that are believed to have been ancient glaciers, as the "Phoenix" spacecraft, which landed near the North Pole, saw the ice melting and witnessed snowfall. She even saw drops of liquid water
It is believed that Mars contained abundant amounts of water, which fell in the past through snow and rain and made rivers, lakes and oceans, and as a result large amounts of silt were deposited. It is possible that life has existed on Mars, and although the temperature on Mars is very low, water can still exist in liquid form if there are salts, and indeed there are salts on the surface of the planet.
Life on Mars is impossible with today's technology.
A study published in the journal Nature Astronomy stated that the process of reshaping Mars to become a life-supporting planet is impossible in light of current technologies.
She added that the formation of Mars or its reclamation "Terraforming" is a hypothetical process aimed at changing the atmosphere of the Red Planet to make its climate more livable by changing the concentration of gases in the air, reducing levels of ultraviolet radiation, increasing atmospheric pressure and raising the surface temperature, indicating that this process depends on Mainly on the release of quantities of carbon dioxide into the atmosphere of Mars.
The new study contradicts what many researchers have previously said that the presence of large amounts of carbon dioxide gas in the rocks of Mars and its polar ice regions can qualify humans in the future to release it to make the atmosphere more dense as well as raise the temperature of the planet and allow liquid water to remain. on the roof .
According to the new study, which was carried out by two researchers from the University of Colorado and Northern Arizona, "levels of carbon dioxide gas - which is the only greenhouse gas present in reasonable quantities on the Red Planet - cannot be used under current technology and carbon dioxide deposits on the Red Planet cannot raise the surface temperature." Mars and its atmospheric pressure in a way that can enable humans to live on it.
"It is not possible to reclaim Mars using today's technology," Bruce Jakosky, lead author of the study, said in his own statements.
Jakosky adds, "Living on Mars under the current conditions is impossible in the absence of the technology needed to extract enough carbon dioxide from the planet's soil, which makes the process of converting Mars into a habitable planet very difficult."
?The study talks about the impossibility of extracting sufficient quantities of carbon dioxide in the light of "current technology"... What about future technologies
Jakosky says: It is very difficult to predict what we will be able to do in the future. In theory, we could manufacture highly efficient greenhouse gases such as freon that would heat the atmosphere. However, the manufacture of these gases on a large scale exceeds our current capacity.
He adds that some people will be disappointed by these results, pointing out that the colonization of Mars and its reclamation is a dream that has been haunting many scientists, but despite the shock these results constitute, the scientific community must still provide the best scientific information to help plan exploration of the solar system on Earth. description limit.
It is noteworthy that the shocking new study comes at a time when scientific studies are escalating aimed at establishing an Earth-like ecosystem on the surface of Mars that gives humans the ability to cultivate on it to obtain food if they choose to live there, while major international institutions such as NASA and prominent personalities such as "Elon Musk" launched it. The American billionaire with South African roots and founder of SpaceX, a global campaign to organize trips to the Red Planet.
Hermann Obgnorth indicated that traveling to Mars requires at least 6 months, and that the road to Mars contains a lot of radiation, which requires more time, effort and food to reach the Red Planet, adding that even if humans reach Mars, the most difficult thing is to return.
And my personal opinion is that there is no life on the planet Mars, and there will be no life on the planet Mars, and no one will move to live on the planet Mars. God Almighty has prepared all the conditions without the intervention of anyone for the sake of life on the planet Earth and determined its place as the third planet in the arrangement of the planets of the solar system, which It is allowed to live on the surface of the earth, so that we are not near or far from the sun, and it harnessed all the conditions that allow life on the planet, including an atmosphere, good soil, gases, rivers and oceans.
