What impact will this space trip have on China?

For the first time, the Chinese will leave their own footprints in space -- this invisible footprint will surely be forever recorded in the memory of the Chinese nation as the most unforgettable step forward. The realization of spacewalks is a historic step for any space-faring power in the world. The splendor of reality always begins with great dreams.

From the global positioning and navigation system on fishing boats and taxis to satellite radio and television stations that are available in almost every household, from weather forecasts and information networks to "space rice" and "space vegetables" on the dining table, ......Today, we are already living in an era of extensive application of the achievements brought by the "space civilization" space, which not only provides us with high resources, microgravity resources, ultra-high vacuum resources, unlimited energy and material resources, but also provides us with vast space resources, and can even open up infinite living space for us and create a new way of life ...... for usHowever, human exploration and development of space has only just begun. Even if we successfully achieve the historic breakthrough of walking out of the capsule, there are still countless mysteries in the infinite universe waiting to be deciphered. Glory and dreams are always closely linked.

As the first nation to produce the dream of flying to the sky, when it was still hungry, it turned the dream of "two bombs and one satellite" into a glorious reality. We have reason to believe that today, when a new round of space exploration has risen, the time has come for the Chinese nation to use its flying wisdom to benefit mankind. .

Enhance China's international status.

China's Long March Rocket Corporation has proposed a plan for space tourismIt is expected that civilian space travel will be possible by 2024. The China Aerospace Science and Technology Corporation Launch Vehicle Technology Research Institute is expected to successfully develop a repeatable suborbital launch vehicle around 2025.

China's space travel plan is expected to be realized before 2024, which means that we are not far away from space travel, this year is already 2022, and at the latest there are two years before we ordinary people can travel to space.

With the rapid development of science and technology and the continuous progress of aerospace technology, some foreign commercial airlines have begun to formulate space tourism projects, and in such an environment, many domestic aviation companies have also decided to do space tourism projects, and China Long March Rocket Company is one of them.

According to the plan released by China's Long March Rocket Corporation, they will carry out China's first ordinary people space tourism project by 2024, which is mainly for [short-distance suborbital flight], and then is expected to complete the formation of a long-distance space tour group of 10 to 20 people in 2035 to achieve long-distance space travel.

According to Han Qingping, the boss of China's Long March rocket, there are two types of vehicles used for space travel, one is a ten-ton load, which can only carry three to five people, and the flight time in space is only 20 minutes. Another 100-ton vehicle can carry more passengers and fly longer in space, but it will cost more.

According to the China Academy of Aerospace Science and Technology Launch Vehicle Technology, it is expected that around 2025 a reusable suborbital launch vehicle will be successfully developed, with which ordinary people will travel to space become a reality. It's still exciting to think about it, at that time going to space travel will be as simple as taking a plane, after all, after the carrier vehicle can be reused, the cost will be greatly reduced, and ordinary people can also afford the corresponding expenses, the reason why only astronauts can travel to space at present is because the carrier vehicle cannot be reused, so the cost is very high, take the first space ticket sold by Green Origin Commercial Airlines, which was auctioned at a sky-high price of $2.8 million.

At present, space travel is mainly divided into two kinds, one is to go to the moon or the International Space Station like an astronaut, and the other is suborbital flight, in terms of the current level of science and technology and the economic conditions that ordinary people can afford, suborbital space travel is more suitable for ordinary people, after all, to go to the deep space of space, the danger factor is relatively large, and the cost is too high, ordinary people are definitely unable to do itChina's space travel is expected to take place around 2025.

You can do that now, too. At present, it costs about 20 million US dollars, and not everyone can travel to space, first of all, they can bear the huge physical burden caused by the rocket launch and all kinds of discomfort in weightlessness.

With the advancement of science and technology, space tourism will be closer and closer to us, and in the near future, the rocket launch capability of the human gate will gradually increase, the comfort of liftoff will also be greatly improved, and with the increase of carrying capacity, large-scale space travel will also be realized.

Scientists have long planned to launch artificial objects into space, and huge artificial objects can be used for space migration, but there are still many problems that have not yet been solved. With the advancement of science and technology, artificial celestial bodies will definitely become a reality, and in the future, a large number of people will immigrate to artificial celestial bodies, and then they will be able to live in space.

If China wants to realize space travel, it will take some time, at least 50 years and 50 years for him to make some preparations in all aspects, 50 years is the best watershed, this watershed is 50 years.

According to the plan of the National Long March Rocket Company, China's first civilian space tourism project will be implemented by 2024 to achieve short-distance suborbital flight. The ultimate goal is to create long-haul tours that can accommodate 10 to 20 people at a time by 2035.

When China will be able to realize space tourism depends on the development of China's space science and technology. At the current pace of development, such a dream should be realized within 50 years.

According to space experts, China is on track to achieve suborbital space travel by 2025.

Within a decade, space travel for ordinary people may be realized. Because commercial aerospace is also a major trend in the development of the entire aerospace industry. There are more enterprises of different natures involved, which is a good boost to the development of the entire industry.

Ordinary people go to space, this should not be a very long-term problem.

In recent years, only Russia has officially offered tourism to the International Space Station, and the United States has private companies that can provide suborbital tours. Xu Yizhong will not be the first Chinese to travel to space, it depends on how much money he has and how good his health is.

PS: China will not withdraw from its own space tourism program in the short term.

This should take another century, because now there is an epidemic, and the development of technology and everything in the world has been sluggish.

Pros: 1. The development of space technology can provide an inexhaustible resource for mankind's future resource shortage.

2. The development of space technology can expand the human race.

Lebensraum. 3. Let human technology be more advanced and create a better living environment for future generations.

Disadvantages: 1 Space junk caused by the failure of space experiments.

will cause changes in matter on other planets.

2. The microorganisms brought out by space experiments can also cause subtle changes in space matter.

3. Too much exploitation of space will bring harm to the earth and mankind.

4. Too much manpower is invested. Material resources. Financial resources. Once you fail, the consequences will be overwhelmed.

Tsiolkovsky, the "father of astronautics", said: The earth is the cradle of mankind, but human beings cannot live in the cradle forever......

First of all, it is important for humanity to have a better understanding. Because our understanding of space is far from enough, a series of questions arise, including where did humans come from? Where did the universe come from?

Did God create it or did He create it? These fundamental philosophical questions require astronomers and philosophers, and depend on the deepening of our understanding.

The second purpose, although we are not human-centered, our space exploration is for the more sustainable development of human society on earth. Is the earth going to be destroyed one day? This question is always one that philosophers need to consider.

The question involves whether there are aliens and whether they have been destroyed. In fact, there are many factors that human beings have encountered to destroy the earth, such as global warming, ecological damage, etc., and it is possible that an asteroid will hit the earth. Because the earth's energy is also limited, it involves whether we need to move beyond the earth in the future, whether it is a small number of immigrants or the entire human race.

I don't think immigration will be possible in the short term, and it will probably be a minority in the future, and it will be impossible to move the entire human race. In order for human society to develop sustainably, it is necessary to solve the problem of environmental protection of the earth and the sustainable use of energy.

Therefore, there must be an overall development goal for space exploration, and there must be a sequence of what to do first and what problems to solve first. In the universe, other things that have a great impact on the earth also need to be studied, such as the sun, which needs to be studied very seriously, because solar activity has a great impact on the earth. For example, when we talk about global warming today, there are two schools of thought, one group believes that it is human activity, and the other school believes that it is a factor of solar activity.

There are many kinds of space exploration, and there are many destinations to go to, the moon is the easiest place to go, and some places are more difficult to go, such as Mars, where to place the exploration of Mars, also needs to have a general consideration.

For the development of space resources, especially the development of minerals on the moon or the development of energy on Mars, the development of helium-3 on the moon

As the earth's resources are increasingly depleted, if human beings can effectively reduce the cost of space exploration and develop the resources of other stars, it is also a solution to the earth's resource problem.

Space journey, my country's space journey again and again, in the face of the development of science and technology, you want to say something.

Dear, I'm glad to be able to answer for you, the development of China's aerospace industry, from "Shen I" to "Shen V", Uncle Yang Liwei has already believed in the "Shen V" to heaven. Successively, the manned spacecraft of "Shen V" Qiao Ye Zao, and the "Shen VI" successfully lifted off, it went to explore the universe, and the two astronauts: Nie Haisheng and Fei Junlong returned victoriously!

What an exciting time, this is the pride and pride of the Chinese people. Thousands of Chinese sons and daughters are extremely excited, and another new initiative has been born! Space will also give us a new living environment.

It will bring rapid development to our Xiaoque's science and technology.

What are the effects of long space travel on human health? Will it alter the human genome? A new study by the National Aeronautics and Space Administration (NASA) has found that space travel does not cause long-term significant epigenetic changes in humans.

This could slightly ease concerns about long-term space travel.

Scientists have recently discovered that space travel may permanently alter the habits of E. coli, making them more closely bound and easier to survive. The current longest-lasting bacterial study in simulated microgravity shows:Even when researchers try to erase the altered traits, this ability to adapt remains. One of the big questions to consider for long space travel is:

The microbes in our body also change with the loss of gravity. Astronauts have weaker immune systems in space, making them more susceptible to disease, so if bacteria become more tenacious, then the danger is greater.

In addition, the researchers found that while in space, astronauts also experienced retinal thickening, weight loss, intestinal microbial displacement, and cognitive decline.

At present, this experiment needs to be studied several more times, especially in view of the increasing number of manned space flights in recent years. E. coli is relatively harmless to humans, but for astronauts on long-term missions, the risk of infection is greatly increased if microgravity also makes it easier for some harmful viruses and bacteria to survive.

Eating and drinking water is a common thing for people living on Earth, but in the weightless environment of space life, the diet of astronauts becomes very complicated and especially wonderful. It can be said that astronauts' nutritional needs, food preparation, supply, and the way they eat have certain particularities, which are very different from their diets for life on the ground.

Space food is essentially the same as ordinary food on the ground, providing energy and nutrients for the human body. However, in order to save space on the spacecraft and payload at launch, the space food carried by astronauts should be as light and small as possible. For example, nutritious dried biscuits and dried sausages can be soaked in water when eating, and the taste can be restored to a taste similar to that of fresh food.

In addition to being able to withstand the influence of special environmental factors in spaceflight, such as shock, vibration, acceleration, etc., aerospace food must also make appropriate adjustments to the nutrients of the diet according to the index of physiological changes of astronauts under weightless conditions. Bone loss requires adequate calcium and appropriate calcium-phosphorus ratios and vitamins from food.
