Scientists have discovered a lake of liquid water on Mars, so can humans immigrate to Mars?

There are roughly two directions for human beings to explore the universe, one is to find alien life, and the other is to find a "second" planet suitable for human habitation. We all know that water resources are the foundation of life, and water in human body can account for about 70%. Without water, it is difficult for human beings to survive. ?

So, apart from the earth, have scientists found water resources available to human beings on Mars, the moon or other planets? Can this plan of emigrating to Mars really come true? ?

For human beings, the moon used to be very mysterious. /kloc-in the 6th century, astronomer Kepler put forward a plan to land on the moon. He also speculated that man would land on the moon 400 years later. Moreover, he also proposed that the center of the universe is the sun, and all the planets are circling around the sun. Although he didn't know there was gravity in the world at that time, he was still curious about these problems.

1969, Armstrong successfully landed on the moon, which "opened" a new chapter for mankind. So far, 12 people have successfully landed on the moon and returned home. However, on the moon, these 12 astronauts did not find water resources, only saw magnificent scenery and a lot of rocks. ?

Forty years later, water was detected from rock samples brought back by the moon. Some scientists think that there may be a lot of ice resources under the lunar crater. However, after many explorations, no water resources available to human beings were found on the moon. ?

Although no water resources have been found, the exploration of the moon is still valuable. In the 20th century, after the first astronauts landed on the moon, they took a picture of the earth in the universe, which was very memorable. Now, the desire to explore the moon has declined, and humans have begun to turn their eyes to Mars.

Mars, the planet "the fourth closest" to the sun, has been "ready to move" for the trip to Mars since human beings achieved the goal of landing on the moon. However, although the Mars landing plan has existed for a long time, 30 years later, humans have not successfully landed on Mars, but many experimental projects related to Mars have been carried out on the earth. ?

One of the projects is the well-known "Mars Migration Plan", whose goal is to send the first human beings to live on Mars. The completion of this plan depends on the development of human science and technology, and is also the only way for human beings to explore the universe.

Over the years, humans have sent many probes to Mars, which provide a lot of information related to Mars. However, in order to realize the plan of Mars migration, liquid water needs to be found on Mars first.

In 20 10, scientists found many dark stripes on Mars. These stripes will change with the seasons. In warm season, stripes will become longer and thicker, and in cold season, stripes will shrink and fade. The change of this stripe makes scientists believe that this is the characteristic of the transformation of liquid water on Mars. ?

20 15 reports that these dark stripes are actually just salt water. ?

However, in 20 17, the stripes photographed by the more advanced Mars probe were called "dust flow" by scientists.

By 20 18, scientists discovered a huge lake about 1.5 kilometers away from the Antarctic ice sheet of Mars, with a width of about 20 kilometers and liquid water. However, this new discovery has not been confirmed. If it is confirmed to be true, this lake will be the first "liquid water lake" on Mars discovered by human beings.

We all know that all living things on the earth need water resources to survive. If liquid water really exists on Mars, then there may be other life forms on Mars. Of course, if human beings want to immigrate to Mars, besides water resources, they also need to consider the distance between the earth and Mars. ?

1965, human beings made their first close contact with mars. At that time, Mariner 4 successfully flew over Mars after a long journey of 228 days.

1969, mariner 6 arrived at mars after a trip of 155 days; In the same year, Mariner 7 shortened the journey to 128 days; Two years later, "Mariner 9" took 168 days and became the first earth vehicle to enter the orbit of Mars. ?

Four years later, Viking 1 successfully landed on Mars for the first time in 304 days. After that, some aircrafts arrived on Mars one after another, but it took about 200-300 days. In this way, if human beings want to immigrate to Mars, they must first solve the problem of travel time. After all, the plane is not very big. If you really want to stay in it for two or three hundred days, humans may not be able to stand it.

A few years ago, scientists did related experiments. In the experimental stage, three men and three women need to stay in a relatively narrow space for one year. In order to simulate the living conditions of going to Mars, the supply of water and food is limited. In addition, the experimenter can only grow fruits and vegetables in the space by himself.

In this experiment, what the researchers want to record is what kind of psychological changes will happen in a closed space for a long time, and what kind of reactions human beings will make in the face of loneliness, harsh environment and long-term monotonous life. ?

A year later, the experimenter came out of the closed space and felt that he was out of the world. Life in the past year has been really painful. Staying in a closed space, they can't breathe fresh air, see beautiful scenery or communicate with people outside. They can only eat the same food every day. The only "fun" is sleeping, because time will pass quickly only when they are asleep.

All six experimenters said that they were no longer willing to stay in such a closed space. From this point of view, it is simply "more difficult" for Martian immigrants to achieve it. In addition to technology, there is also the problem of human adaptation. We have been living on the earth, and it is difficult for us to adapt to the environment of other planets. ?

In fact, life on Mars itself is very difficult. The moon is very close to the earth, and it only takes a few days to go back and forth to the moon, but if you go to Mars, it will take about seven months. If the plane has to carry a lot of materials, it will be more difficult and the journey time will be lengthened.

The United States once put forward a plan that they would send astronauts to Mars in 2033. In fact, the possibility of realizing this plan on schedule is still very low. In addition to overcoming technological difficulties, we should also find astronauts who are willing to go to Mars. After all, going to Mars is risky, and no one knows what will happen.
