It was time to decide on the astronauts. There is a grapevine that BIPU's plan is to carry out the mission by two male astronauts.

Confucius Mei, first of all, felt that she had no hope, and she even packed her bags and prepared to go home.

However, at the end of the day, there was a "fairy" brand insurance company to advertise. Due to the high price, the company is considering a model of one man and one woman, but the company is considering who it is.

It's right to choose a man and a woman, you can't let two big men endorse the insurance T, right?

The base has a lot of headaches when discussing candidates, among the 12 would-be astronauts, 9 are men and 3 are women, who will go?

To become an astronaut, it should be 2 people from more than 50,000 people, and the probability is very low. It is even more stringent than the official astronaut selection in the United States.

In the United States, for example, in 2017, the selection of American astronauts was to select 8~14 people from 18,300 people, and if calculated according to the full admission, the probability of becoming a candidate astronaut was only 0.08%.

It is 74 times larger than the world's most competitive Harvard University, which has an acceptance rate of 5.9%!

To be honest, the mental, physiological, and long-term performance of the 12 people all meet the requirements for astronaut selection. In the end, according to the vote of the base and the company, four people were selected.

At the last moment, the director made the final decision: let Zheng Riqiang and Confucius Mei, and in the final training, we saw that they are full of team spirit and kindness, which is indispensable in space exploration.

More importantly, Zheng Riqiang also has a medical background, and Confucius also has a background in plant production. This could be used in the Martian landing experiment.

This time, the list of 2 people was dramatically set.

As for their trip to Mars, it is possible that Zheng Riqiang's medical knowledge will be used because the landing activities have a very important mission: to observe the growth of human embryos in space.

For a long time, people have wondered if we can create new human beings in space, on alien planets such as Mars, Titan, and the Moon.

At least we know from studies in mice that it is possible in microgravity, but human childbirth in microgravity may not be as smooth.

Space and extraterrestrial planets can cause damage to the adult body, including muscle and bone density loss, hormonal changes, etc., and how these affect the developing fetus need to be studied.

Radiation in the space environment is another challenge that space embryos need to face.

Such a child, even if he can survive, will he become an "alien" in space? Like the movie Godzilla?

If the appearance of a human being changes, is it still a human being?

Therefore, the development of human embryos in space is one of the most important experiments they have to perform.

This is an important move before space migration, and if such a weak embryo can grow well in the dangerous space of space, then there will be no problem with space migration.

Previously, humans conducted a long-term experiment for it, which lasted 30 years and had three major experiments:

The first was in 1996, when the Columbia Space Shuttle sent 49 mouse 2-cell embryos into space, and none of them developed.

The second time was in 2006, when China's Shijian-8 breeding satellite carried out space development experiments on 4-cell embryos in mice, but unfortunately they failed to complete their development in space.

The third was the 2016 Practice 10 mission. This time it was finally successful, and the mammalian embryo developed in space for the first time.

In 2016, Chinese scientists launched the Shijian-10 re-entry scientific experiment satellite, bringing more than 6,000 early mouse embryos into space.

After several days of space travel, it was finally confirmed that the early mouse embryo developed smoothly in space, which was the first time in the world that the development of a mammalian embryo in space was realized.

The results of this study will show that mammals can reproduce in the harsh microgravity environment of space.

Mice can, but humans can?

This time, they are carrying 108 human embryos to see if they can develop in space.

This experiment is also very rigorous, in accordance with ethics and morality, and does not violate the convention of the international mainstream medical community on gene-edited fetuses - embryos are limited to 14 days, and they need to be destroyed after research, let alone allowed to be born.

Can fragile human beings, without the earth, still reproduce?

There is another factor, the epidemic on the earth is raging, 5 years, although there is a vaccine, it is still not controlled, but there are signs of getting out of control, the virus has mutated several times, making it impossible for humans to prevent it.

The virus infects hundreds of millions of people worldwide and kills millions. To add insult to injury, Japan has dumped large amounts of nuclear wastewater in the Pacific Ocean, which has global implications. The conflict between Russia and Ukraine is intensifying, there are signs of getting out of control, and humanity has nowhere to hide, and the best way is to flee the earth.

Even more worrying is the fact that it has been said that NASA has discovered a potentially threatening asteroid 2019 PDC. The asteroid is 260 meters long and 140 meters wide, and has a 1 in 10 chance of hitting Earth on April 29, 2027.

Therefore, immigration to Mars has been included in the agenda of the council.

Hearing that he had been elected as an official astronaut, Zheng Riqiang was very excited.

The base and the company held a grand ceremony, announcing that the two were officially astronauts and would be the first humans to land on Mars.

Newspapers and the Internet are full of photos of the two. At the same time, the flying machine they flew this time was also made public.

It was only then that people discovered that flying saucers really existed.

Back then, since the 40s of the 20th century, an elliptical disk flying machine that emits light has been found over the United States, so people call it a flying saucer or UFO.

Some people say that the flying saucer is made in Germany, saying that in 1945, the Soviet Red Army found a photo of an aircraft with a strange shape in many technical data left by the German army, which is a propeller aircraft with round wings, which is different from any previous aircraft of the German army, which is a flying saucer.

This circular aircraft has a number of advantages, especially suitable for vertical take-off and landing technology, and has a certain stealth effect under the irradiation of radar waves. Some people claim to have witnessed the test flight of this strange flying vehicle, which climbed about 9,000 meters in three minutes and reached a speed of hundreds of kilometers per hour.

Legend has it that during World War II, ** had already begun to secretly develop UFOs.

It is reported that Hitler wanted to rely on the success of the development of UFOs to quickly win the world war. In February 1944, the UFO skeet was probably already reaching speeds of 2,000 km/h (556 m/s).

Later, Hitler's senior air force general Goering once mentioned that the "secret weapon V7" was likely to determine the outcome of World War II.

Although it has been almost 70 years since the end of World War II, the UFO mystery of ** has been ignored with the passage of time, but people still talk about the "V7 plan" about ** again.

The headline of the world's largest circulation newspaper is:

Wow! Two humans will fly a flying saucer to Mars!

As a supporting package, BIBU is soliciting "the first words of landing on Mars" from all over the world:

If you were the first human to land on Mars, what would you say?

Authors who are adopted will receive a reward of $200,000.

After all, this is an epoch-making moment. On July 20, 1969, astronaut Neil Armstrong set foot on the moon for the first time and uttered the stirring words:

That's one small step for （a） man， one giant leap for mankind。 "It's a small step for the individual, but it's a giant leap for the human race."

In fact, many people are very enthusiastic about what to say when landing on Mars, and they have sent their ideal words.

As a result, this "mini-survey" caused a wave of enthusiasm, and 12 million pieces of information were submitted.

But in the end, only the following 5 comments were accepted, and the total of $200,000 was shared.

The five comments are (in order of recommendation)

1. Mars, humans are coming (recommended by 1016531 people).

2. Mars, here we come (recommended by 985211 people).

3. Space immigrants, go you! (718654 recommended).

4. The first step to conquer the solar system (recommended by 432396 people).

5. It's a big step for the individual, a small step for humanity (410,380 recommended).

In fact, as we said later, these five sentences are not used later.
