Is there water on Mars, is there water on Mars?

NASA's Mars rover had already speculated in previous months that there might be a large amount of water below the surface of Mars.

Washington, June 27 (Xinhua) -- After analyzing the observation data of two Mars probes in the United States, scientists found that the North Pole region of Mars may contain a large amount of frozen water, and the reserves are about one-third more than that of the South Pole region of Mars. The new discoveries are of great significance for finding signs of life on Mars and determining future Martian exploration sites.

During the Martian winter, about a third of the carbon dioxide in its rarefied atmosphere accumulates in the polar regions of Mars in the form of dry ice, covering the soil below. The thick dry ice at the polar regions of Mars dissipates with the onset of spring and summer, exposing the soil layer underneath.

The U.S. Mars Odyssey rover found signs of the presence of a large amount of frozen water in the South Pole region of Mars last year. Russian and American scientists jointly wrote an article in the US journal "Science" on 27 July, saying that in their current study, they not only used the observations of the gamma-ray and neutron detection devices on the "Odyssey" to analyze the seasonal changes in the dry ice layer in the North Pole region of Mars, but also combined the observation data of the laser altimeter carried by the US "Mars Global Surveyor," which is also currently working in Mars orbit. This altimeter directly measures the thickness of the dry ice in the Arctic region of Mars in different seasons.

The results of the analysis of Russian and American scientists show that when the dry ice covering the North Pole of Mars disappears with the change of seasons, the large area below is characterized by rich underground frozen water. The head of the research team, Dr. Mitrofanov of the Russian Space Research Institute, said that "in some of these places, the frozen water content by volume exceeded 90 ".

According to Boynton, a member of the research team at the University of Arizona in the United States, the frozen water of the Martian North Pole may be located in a very shallow layer of soil below the surface of Mars. He said that digging anywhere in the North Pole of Mars is about a few centimeters to 30 centimeters or so, and you may find water in a frozen state.

Scientists have not yet found out.

Is there really water on Mars?

made of solid water, that is, ice.

There is water, there is a lake of liquid water.

A team of researchers led by the Italian Space Agency published a report in the journal Science that they found a lake of liquid water about a kilometer below the surface of the Martian South Pole ice sheet. This discovery is the first of its kind in the world, and it is expected to add new content to future Mars exploration and lead to a new ** on whether there is life on Mars.

A team of more than 30 researchers from the Italian Space Agency, the Italian National Institute of Astrophysics, the Italian National Research Council and three Italian universities analysed observations from the radar equipment on the European Space Agency's Mars Express rover between May 2012 and December 2015.

It was found that the radar signal in the Antarctic ice sheet of Mars was obviously abnormal, and the shape was similar to that of the liquid water lake under the Earth's Antarctic glacier, indicating that there may be stable liquid water on Mars.

There is water on Mars, and there's a lot of water. Based on observational evidence, Mars may have previously covered large areas of water, and similar groundwater gushing has been observed, with partial retreat of the Antarctic ice cap, radar data showing the presence of large amounts of water ice at the poles and beneath the surface in the mid-latitudes.

Mars is basically a desert planet, with sand dunes and gravel all over the surface, no stable liquid water body, and an atmosphere dominated by carbon dioxide is thin and cold, with sand and dust suspended in it, and dust storms often occur every year.

Compared to Earth, the geology is inactive, and another unique topographic feature is the stark difference between the northern and southern hemispheres: the south is an ancient, crater-filled highland, and the north is a younger plain. Both of Mars' poles have a polar crown composed mainly of water and ice, and the dry ice on top of it grows and wanes with the seasons.

No water has been found at the moment, but there will be water in the future.

Since the Sun constantly devours the nearest planet and then releases electrons through the sunlight, its own volume is also under pressure.

The ancient Earth was farther from the sun and smaller in size, giving rise to giant creatures and ice ages.

As it gets closer to the Sun, it gets hotter and hotter, and it absorbs the water that evaporates from Venus, and then it gets bigger and bigger. As a result, large creatures are too heavy to survive, and humans appear.

On the riverbed of Mars, rivers were formed by liquid gas in ancient times. Now it has evaporated into the atmosphere.

In a few more years, tens of millions of years, the Earth's temperature rises, the atmosphere and water evaporate, and are blown into outer orbit by the solar wind and absorbed by Mars. When the time comes, Mars will be the second Earth.

Observational evidence now suggests that there is no liquid water on the surface of Mars, although there have been traces of water erosion on its surface. Mars is basically a desert planet with sand dunes, gravel and no stable bodies of liquid water.

Mars (Mars) is one of the eight planets in the solar system, the astronomical symbol is, is the fourth planet in the solar system from the inside to the outside, belongs to the terrestrial planet, the diameter is about 53% of the earth, the rotation axis inclination, rotation period are similar to the earth, and the rotation time is about twice the earth's rotation time. In the West it is called "Mars", the god of war. The orange-red exterior is hematite (iron oxide) on the surface

Mars is basically a desert planet with sand dunes, gravel and no stable bodies of liquid water. The atmosphere, dominated by carbon dioxide, is thin and cold, with sand and dust suspended in it, and dust storms occur frequently every year. Mars has a polar crown of water ice and dry ice at both poles, which waxes and wanes with the seasons.

Compared to Earth, the geological activity is relatively inactive, and most of the surface landforms were formed during the more active period of antiquity, with dense craters, volcanoes and canyons, including the highest mountain in the solar system: Mount Olympus, and the largest canyon, Mariner Canyon.

Another unique topographical feature is the stark difference between the northern and southern hemispheres: the south is an old, crater-filled highland, while the north is a younger plain.

Mars has two natural satellites: Phobos and Deimos, which are irregularly shaped and may have been captured asteroids. On Earth, Mars is visible to the naked eye, with a maximum brightness of magnitude, and is darker than Jupiter and Venus among the eight planets.

The poles of Mars are cold with water, and the water is covered with thick ice, and the water on the poles of Mars is seeping into it. There is water on Mars, and Mars can form water, but the formation of water in most places on Mars is less than the evaporation of water, so it can be inferred that there is groundwater on Mars, and there is water in caves, and life is easy to produce when there is water.

There is information sent back by ESA's "Mars Express" to prove that the South Pole ice sheet of Mars is mainly composed of a mixture of ice and dust, and a small part is composed of dry ice (solid carbon dioxide). According to the information sent back by the two Mars probes in the United States, as well as previous research results, Mars once had a large area of oceans and a large number of lakes.

So there's a lot of water on Mars, and it's found in the Martian atmosphere, in the polar ice caps, and maybe there's water underneath it.

There is currently scientific evidence that there is water on Mars, which is one of the reasons why it may be the future human habitation.

What is the reason there is water but no life on Mars? Now it has finally been broken by scientists.
