Underground lakes have been discovered on Mars, could there really be life in them?

Some space scientists said that there was a major discovery on Mars recently, which can be described as a leap mutation: on the extremely cold planet of Mars, there is a 20-kilometer-wide underground liquid lake after the feedback information sent by the satellite. This is the first large-scale water source discovered by scientists, and the presence of this subglacial lake on Mars, a proud red star, shows that there is a high probability of life here.

This major discovery is good news for the whole of humanity, and astrobiologists are excited, after all, it is a new hope that there may be life in the depths of Mars, a mysterious and unknown world that attracts them to explore the future. <>

The most surprising thing is that this magical lake is located in an ultra-low temperature environment of minus 68 degrees, under normal circumstances, the water at this temperature should form a hard stone like ice, but the water of this lake still exists in a liquid form, which has to be said to be a scientific unsolved mystery, the reason for this should be the high salt content in the lake, so it will remain liquid, and the lake water should be extremely salty.

This can be said to be a new milestone on the road to exploring Mars, in fact, humans have discovered liquid water on Mars a long time ago, but the existence of such a large liquid lake is really too surprising, astronomers also expressed very excitement, people are more interested in the exploration of Mars. <>

Speaking of the water in this lake, the temperature is definitely below freezing, probably because the abundant salt content of the water ensures its liquid state. People must be very careful about this, because its salt concentration is unimaginable, and it can be fatal to microorganisms on Earth, because of the conditions, it is impossible to sample, so it is still in the speculation stage whether there is really life on Mars.

Underground lakes have been found on Mars, but that doesn't mean there's life in them.

There will definitely be life in the underground lake, because it is also part of the ecology.

I think there is life wherever there is water, because the condition for life to exist must be water.

You don't have to have life, it's air and water, isn't it?

It's possible, but it doesn't fully mean that there is life.

I think it's very possible, but we humans haven't discovered it yet.

I think Mars could become our second home. So there may be life.

I think it's very possible that life is there.

I don't think this can be concretely represented that there will be life.

There is a lot of salt stratification in it, which is not suitable for the survival of various organisms.

The temperature is very low, rich in salt, and not suitable for life, and this is also the first lake to be discovered, and most people are very curious, so they are still in the process of observation.

The first underground lake discovered on Mars, this lake has a high salt content and a low temperature, which is not suitable for life to survive.

A large amount of salt is present. And the temperature in the lake is very low, so the lake is not suitable for life at all.

According to long-term research on Mars, there used to be a large amount of liquid water on Mars. However, today's Mars is a barren desert planet with no stable liquid water, only a small amount of liquid water that exists periodically. So, all the water on Mars is gone?

The most fundamental reason is that the mass of Mars is too small, and the surface gravitational acceleration is also small, resulting in a small escape velocity on the surface. Mars has a mass of kilograms, which is only 11% of that of Earth, and the gravitational acceleration on the surface is m s 2, which is only one-third of that of Earth, and the surface escape velocity is kilometers per second, which is also less than that of Earth's kilometers per second. As a result, gas and water molecules on Mars are more likely to escape than on Earth.

Mars was formed with a magnetic field, but later, when the inner core of Mars cooled, iron no longer flowed, and the Martian magnetic field disappeared. After the disappearance of the Martian magnetic field, it caused a series of chain reactions. The sun shoots outwards a stream of high-velocity charged particles, known as the solar wind.

If a planet has a magnetic field, it will deflect the solar wind and prevent it from approaching the planet's surface, thus acting as a protective force.

If the planet does not have a magnetic field, the solar wind will bombard the planet's atmosphere directly, colliding with the atmospheric molecules, and the atmospheric molecules will gain a velocity after colliding, if this velocity is greater than the planet's escape velocity, the atmospheric molecules will break away from the planet's gravity and escape into interstellar space. Mars is the case for this mind. When the magnetic field, the first layer of Mars' defense, disappeared, the atmosphere began to gradually escape and disappear under the bombardment of the solar wind.

Water is the source of life. The discovery of a large amount of frozen water on Mars has once again ignited hope for the exploration of extraterrestrial life. For thousands of years, humans have dreamed of contact with extraterrestrial life in the form of myths or fantasies, but no conclusive evidence of life beyond Earth has yet been found.

However, it is not difficult to imagine that in the early rivers and lakes and oceans of Mars, Martian microorganisms may also evolve like the earth, and even strange Martian aquatic animals may evolve. However, as the climate of Mars becomes colder and drier, these Martian creatures become extinct in large numbers, and very few may be in a state of deep freeze. The discovery of frozen reservoirs on Mars has undoubtedly added a new impetus to the landing of humans on Mars.

In 1969, after the dream of human beings to go to the moon came true, the next goal was to realize the dream journey to Mars.

The lakes on Mars, because the surface temperature of Mars is too high, it is easier for water molecules to escape, and after the magnetic field of Mars disappears, the water is also evaporated.

The lakes on Mars all disappeared after the movement of the Tong Beiling under air pressure, because there was not a lot of water on Mars, so they all dissipated in the process of rolling and defeating.

It is probably because of bad weather that most of the lake has disappeared, and it may have become groundwater, or it has evaporated completely.

It may have evaporated, or it is possible that the water was hidden deep in Mars, where frozen water was found.

Italian researchers have discovered that there is a lake on Mars! They used satellite radar to dig under the thick ice at the South Pole of Mars. They first reported their unique findings in the journal Science on July 25, 2018.

Historically, it is not uncommon for Mars to have large amounts of water in solid or gaseous form, and according to the evidence left by the rocks on the Martian surface, there was once liquid water on the surface of Mars. But there has been debate about whether liquid water still exists on Mars, with some suspecting that it may be hidden beneath the frozen poles of Mars.

Italian researchers turned to instruments on the European Space Agency's Mars Express orbiter to get some answers. It is known as the Martian Underground and Ionosphere Detection Advanced Radar. Marsis's GPR sends pulses to the surface of the Red Planet and calculates the time it takes for them to be reflected back to the satellite, as explained in this ESA press release.

It also tracks the strength of the return signal. These two factors depend on the material encountered by the radar pulse. This data, in turn, can be used to map the seafloor.

So, with the help of radar, scientists found that the south pole of Mars is covered in multiple layers of ice and dust, extending to miles (kilometers) below the surface of the earth. Underneath that, however, they found an area whose characteristics indicated that it was a lake, which scientists believed was water filled with salty sediments.

Roberto Orosei of the Bolo Pichainia Institute of Radio Astronomy is the lead researcher on the Marsis experiment and the lead author of this article. "This subsurface anomaly on Mars has radar characteristics that match water or water-rich sediments," he said in a press release from the European Space Agency.

According to the press release, the lake is about 12 miles (20 kilometers) wide.

Only found a liquid lake, but life has a certain selectivity for water quality, a certain trace element in the water exceeds the standard, it can become poisonous water, if life exists in poisonous water, this statement is not scientific, maybe the life of Mars has the ability to adapt to these resistance, for whether there is really life we do not stick to the actual speculation is also unscientific, so only according to scientific in-depth research or the shooting of the pilot probe ** is more convincing.

As an ordinary person, although the earth is like a village compared to the universe, the village is also big enough, and there are very few people who travel to their own country, as long as they have a house, a car, relatives and friends, it is enough, and visitors from outside the world only do beautiful reverie!

In ancient times, liquid water existed on Mars, but now scientists have concluded that Mars is extremely arid. The atmosphere is mainly composed of carbon dioxide and red dust, and the temperature is only 20 degrees Celsius in summer and minus 140 degrees Celsius in winter, making it uninhabitable for humans. The current rocket method is definitely not good, the weight of a few thousand tons can only hold up 20 tons of cargo, if the electromagnetic launch is successful, you can establish a base in geosynchronous orbit, the tonnage of ten aircraft carriers, store materials, and build a space greenhouse.

As the old saying goes, "the soldiers and horses are not moved, the grain and grass go first", you want to transform Mars The idea is very good, but have you thought about what kind of tools are needed to transform it, and how can they get to Mars? If you could transform Mars, what would it bring to Earth? How can these be resolved?

Think about this and then consider transforming Mars.

In fact, the future development of Mars is still realistic, using Musk's launch vehicle to put all kinds of infrastructure materials on the fixed surface of Mars, and then return to repeat, and then send the construction team to build a fortress to build an indoor environment suitable for human life, and gradually expand, so what is urgently needed now is the returnable launch vehicle and enough power energy, Mars colonization is not a dream, it may be realized within 50 years.

It's true, because according to some detection reports, it is very likely to be true, there are many lakes under the surface of Mars, and more comprehensive research on Mars will be conducted in the future.

So far, there is no scientific evidence that there is life in the lake. Everything is based on some scientific inferences. With the continuous development of human science and technology, one day human beings may be able to better explore Mars and prove whether there is life in it.

In the June 2021 issue of the online edition of Geophysical Research Letters, it was said that radar data showed that there may be dozens of lakes beneath the surface of Mars' South Pole.

In fact, in 2018, a team of researchers announced after analyzing data collected by the European Space Agency's Mars Express rover that they had found evidence of a huge underground lake in the South Pole region of Mars, which appeared to be about 19 kilometers wide and located kilometers below the dry, cold surface. The team then tracked the discovery using the Mars Underground and Ionospheric Detection Radar (Marsis) on board the Mars Express and found evidence of three more underground lakes, each about 10 kilometers wide.

Although it was discovered that it was indeed a lake, scientists still don't know what allowed so many relatively shallow lakes to be preserved.

It is also possible that there are dozens of lakes under the surface of the South Pole of Mars, but the current science does not meet the standards for this kind of exploration of Mars, so it is only a guess and cannot be confirmed.

Not true, such a statement is very incorrect, and there is no evidence to prove it.

It's true, because it can be shown by radar, and these lakes are very abundant and have great development value.

This is not true. There is no official saying that this is true, so don't believe the rumors, don't listen to some rumors.

There have been microorganisms, and there are currently no human-like existences. After landing in Gale Crater on Mars in 2012, Curiosity discovered a thermal anomaly in a 5-meter-deep trench near the landing site known as Yellowknife Bay. Ground personnel remotely controlled the "Curiosity" to drill and analyze the sedimentary rock at the bottom of the ditch, and found that 3.6 billion years ago it was a rippling lake, which existed for at least tens of thousands of years.

Researchers pointed out at the annual meeting of the American Geophysical Union held in San Francisco on the 9th that the pH value of this lake bottom area is neutral, the salinity is very low, and it should have been a freshwater lake. Key elements of life such as carbon, hydrogen, oxygen, sulfur, nitrogen and phosphorus have also been discovered, meaning that the lake supports the survival of prokaryotic microorganisms.

For example, inorganic autotrophic microorganisms that can decompose rock components and minerals for energy. These microorganisms are often found in some caves and hydrothermal vents on Earth.

Life on Mars, scientists have been studying whether there is life on Mars for thousands of years. Now, space experts have pointed out that there is a huge amount of frozen water under the surface of Mars, and that water is the source of human survival. With the continuous development of science, Mars has the potential to become a second Earth suitable for human survival.

Mars has spring, summer, autumn and winter, day and night, but due to the extremely poor heat conduction and heat storage capacity of Mars, the temperature difference between day and night in the four seasons is surprisingly large, the highest is 30, and the lowest is -222. Mars has an atmosphere, but its atmospheric pressure is less than 1 of Earth's atmospheric pressure.

95% of the atmosphere is carbon dioxide, as well as nitrogen and argon, as well as more than 30 kinds of trace gases, but oxygen is pitifully scarce and has become a rare gas. Water vapour in the atmosphere is even rarer, averaging 0 01 of the total atmosphere. Although Mars has a "riverbed" with branches and veins, and a "seabed" that is 1,500 kilometers long and more than 60 kilometers wide, it has no water and does not have any conditions for life.

In addition, the results of space exploration of the solar system have proved that there are no signs of life on the moon, Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune, and only the beautiful earth in the solar system has the conditions for the existence of life.
