The overall feeling of the office is luxurious, elegant, simple and atmospheric. African rosewood office tables and chairs show the manager's personal style and bring together the exquisite office decoration effect.

Due to the increasing size of [781], it was very laborious to manage, but fortunately only the personnel and scientific research were in charge, and the general affairs were handled by deputies. The research team spends most of their time in the lab and spends very little time in the office. Having just received a fax from the China National Space Administration, he walked out of the office and took the elevator to the lobby on the first floor. Push open the turnstile of the large and bright foyer, walk out of the office building, go around to the right side of the office building, and walk towards the experimental area. It is a large complex of tall buildings with wide roofs and several three-storey buildings, separated from the office building by a mesh wire mesh.

This route is very, very familiar, and when I am not on business or have nothing to do, I will come here from time to time. In the synchrotron radiation laboratory, Dong Qing and several scientific researchers are operating on the electronic workbench. Here they are said to be familiar with each other, and they can feel every subtlety with their eyes closed. How important it is for them to be obsessed with the exploration of the basic laws of nature and to reveal the secrets of the natural world by means of physical experiments. From optical thin film to vacuum coating, Dong Qing's retrospective is deeply impressed, and every step is the crystallization of technology and sweat. Looking up at the window, a figure flickered by. Hao Qiuyan was wearing a black T-shirt and radiation-blocking glasses as he walked in the direction of the particle beam laboratory. Dong Qing is an optimistic little old man, with a round face, plump facial muscles, gray hair, and a cleanly shaved beard. Dong Qing pushed open the door and called him behind him, and when he heard someone screaming, he stopped. Dong Qing walked over with a smile, "I haven't seen you for many days." ”

Hao Qiuyan also had a kind of joy on his face, and asked him: "How is this National Conference of Electronic Engineers?" ”

Dong Qing replied: "Very good, the radiation effect and reinforcement technology of LSI and VLSI are still the mainstream, and at the same time, the SEE research of discrete devices and linear circuits, the radiation effect and reinforcement technology of optoelectronic devices, the radiation effect and reinforcement technology of MEMS, the packaging and reinforcement technology, and the irradiation test method and evaluation have been deeply discussed and studied. ”

"So many projects?"

"Isn't it, aerospace exploration, international competition is fierce. The Americans are preparing for a manned landing on Mars, and we are still in the exploration phase of Mars. ”

Mars is up to 400 million kilometers away from the Earth, and the probe will go through about 7 months of cruise after the separation of the rocket and the rocket, and then be captured by Mars gravity, and then separated from the landing rover after the separation of Mars, and then enter the mission orbit to carry out the global orbit of Mars. At the same time, to carry out relay communication for the landing cruiser, it is necessary to take into account the needs of orbit and landing in the orbit design.

Constrained by the laws of celestial movements, there is only one launch time every 26 months. After entering the Martian atmosphere, the landing rover descends to the lunar surface after aerodynamic deceleration, parachute deceleration and thrust reverser engine power acceleration. Carry out orbital surveys to explore the Martian magnetosphere, ionosphere, and atmosphere. There are also the topographic and geomorphological characteristics of Mars, the detection of the Martian magnetosphere, ionosphere and atmosphere, the composition and distribution of Martian surface materials, geological characteristics and tectonic divisions, etc.

During the time when he went out for a meeting, Dong Qing was suffocated, and these people who attended the meeting were all discussing academic issues, and they had no time to chat, and it was not appropriate. Hao Qiuyan is a person who likes to socialize, no matter how old or young, he can talk, and his popularity is very good. Not to mention Dong Qing, who regards Hao Qiuyan as a confidant and the best person to confide in, said with great interest from beginning to end that the Radiation Assessment Detector (RAD) used by Curiosity had detected two types of radiation particles on Mars between the end of 2011 and 2012. NASA announced that Curiosity will conduct radiation tests on the surface of Mars, and astronauts landing on Mars will be exposed to extremely high temperatures and extremely harmful space radiation, with doses exceeding the range that astronauts can bear. One is the radiating material of solar energetic particles (SEP), which are released during solar eruptions; Due to the relatively low amount of energy it emits, it can be detected by conventional spacecraft shielding materials. The other is the galactic cosmic rays, which release much more energy than the previous ones, which also makes it more difficult to use traditional materials to detect them. If an unsuitable shielding material is used during the test, it may also cause an increase in the radiation dose.

Now, the Mars Migration Program has attracted widespread attention around the world, and NASA, as the first agency to "land" on Mars, has conducted relevant research on the issue of Martian astronauts. Since everyone reacts differently to the same particular environment, and it is unknown how humans will react to life on Mars; As a result, researchers far away on Earth have no way of knowing the mental reactions of these immigrants. (NASA) has awarded $1.3 million to psychologists at Michigan State University for research in the hope of developing sensor 'accessories' that can monitor astronauts' mental states. ”

Hao Qiuyan, "Rocket propulsion is a high-power device fueled by hydrogen and oxygen, and human aerospace technology is still very clumsy; But there is no way, we can only do this at the moment, and we need a high level of global science and technology. ”

In this regard, Dong Qing was relatively indifferent, "Mars exploration will take more than ten years, and scientists can only have expertise in their own fields." I'm not that interested in space knowledge, but I know a little bit about it. We need a lot of energy to explore space, like our spacecraft, and it takes a lot of work and precise calculations to get astronauts back to Earth safely. ”

As a member of the managers, aerospace technology is what Hao Qiuyan is more concerned about, and without aerospace technology, human beings on the earth can only sigh with admiration. When he spoke, he would look at Zuo Haiyu's laboratory, looking very eager, this optimistic little old man was talking to himself, and he was embarrassed to leave. Hao Qiuyan, "Our Mars rover also needs better anti-radiation materials. ”

"Yes, the whole team of the state is working on this kind of research. I was also curious about the scientific evidence that Gale Crater was once a huge lake in the past. This is the result of the analysis of the Modulated Laser Spectrometer (TLS) on board Curiosity. Showing a very low methane background, its levels soared more than 10-fold in just 60 Martian days. Scientists believe that this phenomenon may be caused by organisms similar to bacteria on the surface of the star. The temporary rise in methane gas, i.e., the sudden rise and fall, suggests that there must be some related gas sources on Mars. This source may be living organisms or non-living organisms. On Earth, 95% is produced by microorganisms, but there are many, many abiotic processes that can also produce methane, such as the reaction of water and rocks. Scientists are cautious about drawing conclusions, but say that the production of methane gas from life is one of several possibilities. ”

He didn't look moving, he was talking casually, but he seemed to be very interested. Hao Qiuyan, "It seems that Brandenberg's nuclear explosion hypothesis is promising. ”

Dong Qing knew that he didn't have to be far-fetched about this kind of problem, and as an outsider to the problem, he seemed to be willing to get involved; He took off his glasses to relax his eyes and put them back on. According to the newspaper release, "About 4 billion years ago, Mars had enough freshwater to form clay minerals. Not only did Curiosity search for targets for Mars' ancient habitable environment, but it also discovered that this habitable environment was more recent than originally thought. Mars has undergone a severe drying process, leaving the remaining liquid water on the surface to be highly acidic and highly salin. The question is whether the soil minerals in the Yellowknife Bay area were formed in the early days in the outer edge of Gale Crater and then fell down, or whether they were formed later in the later period, when water currents transported material particles from Gale Crater to the bottom and deposited them. ”

Hao Qiuyan said casually, "Where there is water, there is life." ”

Dong Qing sighed slightly, "Varman said that montmorillonite is a typical lake sedimentary clay mineral. On Earth, rich biological habitats can often be found in places where montmorillonite exists. The other is that during the 10-month period that Curiosity measured on Mars, there were no solar eruptions that affected Mars, because about 95% of the radiation dose came from cosmic rays. ”

"It's like pouring cold water on us."

"This is symbolic analysis, just a small step in exploring the universe; The changes in the thinking of human beings on the earth need to go through an avalanche of tidying. ”

"Time transcends a lot of things."

"If you can't do it, life will always be sealed."

"Don't be so pessimistic, but it's easy to understand what you're doing so far. China has made extensive use of modern management theories and methods such as systems engineering, parallel engineering, and matrix management, which have made a major breakthrough in China's space technology. Although it is the time when the stars are shining, there is still a gap compared to the countries with advanced aerospace. ”

"Just do your job."

"Every job needs to be done one after the other."

"Do more now, and I will have a memory after retirement."

"The height of talent is the height of the career, and at present, our country is solving it, and the age structure has reached youth."

After chatting for a long time, I saw that Hao Qiuyan's gaze was always wandering, there should be something to do, Dong Qing, "I won't delay your time, where are you going?" ”

"Go find Zuo Haiyu, the China National Space Administration will send a fax, let us report tomorrow."

"Isn't it okay to make a phone call, and you have to run it yourself."

"The landline is not tightened, and the mobile phone is not answered."

"I'm busy, hurry up and take a look."

A bright moon sprinkled silver light on the sea of clouds, looking out from the cabin, a silver-white world, the moonlight shone on the sea of clouds, like a silver road.

Hao Qiuyan straightened his body: "Can you guess the content of the space agency meeting?" ”

Zuo Haiyu: "It should be a matter of the moon base." In the early years, NASA was reluctant to cooperate with us because the China National Space Agency was a military member. ”

"Americans always like to speculate that international space cooperation is a trend, and they are afraid of wolves and tigers. Is U.S.-China Space Cooperation Possible? What does that mean? There is a growing debate about U.S.-China space cooperation, and the crux of the question is what to do with a 2011 bill in the U.S. Congress. The bill prohibits NASA from engaging in space-related bilateral cooperation with China. ”

John Rogersden argues that U.S.-China space cooperation needs to be promoted at the highest level, and "the first step is for the White House and Congress to work together to remove the current unwise restrictions on such cooperation." China has become the third country to put its citizens into orbit, and it is doing well, but its current manned space flight is only comparable to that of the United States 50 years ago, and China has a lot to learn from the United States. From the U.S. point of view, the main reason for space cooperation with China is political, not technical. To explore space, it is certainly not possible for one country to fight alone; It seems that most of the planets in the Milky Way, are those large planets that have hydrogen around them; The main component of stars is hydrogen, so stars are the raw materials that make up the planetary groups. ”

"Not necessarily, according to the exploration: the density of the atmosphere on Mars is only about 1% of that of the Earth, very dry, the temperature is low, the average surface temperature is 55 °C, and water and carbon dioxide are easy to freeze. Its thin atmosphere is mainly composed of carbon dioxide (95.3%), nitrogen (2.7%), argon (1.6%), trace amounts of oxygen (0.15%), and water vapor (0.03%). In other words, there is no hydrogen on the periphery of Mars, so it is a desert planet. Transforming Mars to raise temperatures, evaporate water from the ice, and form hydrogen and oxygen in the atmosphere could change the ecology there. Of course, this is based on astronomical detection, and it can also be said that it is helpful for the detection of life. Returning to the issue of cooperation in space, the refusal of the Americans to cooperate with China prompted us to start anew and build our own space station, and moreover, a lunar base. ”

"The Americans guess that we landed on the moon for mining, and they have a lot of ideas about our exploration of Mars."

"The competition in international space is fierce, it's all psychological, and the Americans go to the moon and Mars just for fun? It is also a good name. ”

"The South and North Poles are the same, and it is better to separate them, so as not to interfere with each other."

"Cooperation is still cooperation, but there is a limit. The third phase of the U.S. Mars program, which includes living and working on the Martian surface and in a transport spacecraft, will land on Mars in 2030. But the U.S. National Academy of Sciences has unveiled their timetable for landing on Mars, with plans to send humans to Mars between 2037 and 2050 for tens of billions of dollars. ”

The expression on Zuo Haiyu's face tense, "What can Mars tell us about the past, present, and future of the earth?" ”

Hao Qiuyan seemed a little proud, "Although there may not be intelligent life, the exploration program aims to explore whether there are lower life forms outside the earth, and will also compare terrestrial planets to study the origin, formation and evolution of the solar system." ”

Zuo Haiyu also made a suspicious judgment, "Maybe Brandenberg's hypothesis is right, there must have been intelligent creatures on Mars, 'Martians', and due to unexpected reasons, the Martians were wiped out." ”

"Maybe you can't look at the problem with a purely scientific attitude, Mars not only tells the earth about its past, but also about the present of the earth."

"The U.S. lunar base is at the South Pole, on the edge of the Shackleton Crater; Russia may establish a permanent base on the lunar surface between 2027 and 2032. Where will China be? ”

"It's hard to say, it needs to be demonstrated. It will land on the moon in 2030 and build an unmanned lunar base in 2040. ”

In the moonlit and starry night sky, there will be a lot of reverie sitting in the passenger plane, Hao Qiuyan said, "After Mi Di disappeared, I also made a deep reflection, and my thinking was a little extreme before. The Kunlun civilization of the earth, the Pacific Rim is sowing, and it belongs to the same earth, and we humans have long been a complex mixture of dragon and phoenix bloodlines. ”

"The source of the great bloodline. The earth is full of people, the moon has been waiting around for billions of years, and we humans have a rich imagination. The moon's south pole is the region that receives the most sunlight, which helps the base to use solar power to generate electricity, and the abundance of water and minerals in it can reduce operating costs. ”

"It's all a priority, the electromagnetic environment on the far side of the moon is very clean, and if you can put a low-frequency radio spectrometer, astronomers can receive more data and fill in the gaps in human research."

"Yes [781] very much."

"Yes, we need this kind of high-definition astronomical equipment. Now that particle beams are put into use, what's next? ”

"Always urging me, it's not enough to put it into practice, the launcher is still relatively large, and it needs to be further improved. Subatomic particles, lasers, and particle beams are all top priorities. ”

Hao Qiuyan smiled 'hehe': "I'm not stirring up the situation." ”

Zuo Haiyu, "Science should be gradual, step by step. We know that for the microcosm, we must not understand it with the concept of the macrocosm. The nature of light does have wave-particle duality; It has both wave and particle properties. ”

"Contemporary physical theories are all symmetrical, but experiments have many asymmetry."

"Such a scientific topic can only be solved step by step; Don't forget, we are speaking from the standpoint of the planet. ”

"Yes, the relativity of simultaneity was derived by Einstein on the basis that the speed of light is constant when measured in any coordinate space, specifically, by Einstein commanding photons to move at constant speed in two coordinate spaces that are moving relative to each other at the same time. But in fact, photons will not obey Einstein's orders, in the unification of nature "What is time and space" we already know that coordinates are divided into physical coordinates and mathematical coordinates, and no plasmid can move in two physical coordinates at the same time. Therefore, the relativity of simultaneity, which Einstein spoke of, does not exist. Of course, some people will say that light is not a particle but a wave, and that waves and particles are different, and there is no basis for denying the relativity of simultaneity. The theory of relativity is a descriptive theory rather than a theory of lattice matter, and it cannot say why mass and energy are converted into each other, that is, what is the mechanism of transformation; A physical phenomenon can be described by multiple theories, and countless facts have proved physical laws rather than a single descriptive theory. ”

Relativity obsessives will also use the theory of relativity to explain some physical phenomena that they cannot explain in a far-fetched way. This is not an unfounded question, they are all well-known figures in the Chinese scientific community. As the backbone of China's science and technology, we certainly understand that in the sixties and seventies of the last century, China's science and technology lagged behind the advanced countries by a quarter of a century. Relying on a correct path of leadership, a scientific and technological army that has been carefully cultivated, and a hard-working, courageous, and hard-fighting team, China's aerospace technology is a witness after decades of hard work.

'Hehe' smiled, Hao Qiuyan, "These are just thinking problems, human beings have not crossed the solar system yet, the current theory is still useful for the earth, but in the future, interstellar travel will be realized, and the entire physical system should be rebuilt." ”

Zuo Haiyu asked the stewardess for a bottle of mineral water, took a sip and said, "The record must always be exceeded, otherwise, science will stagnate." We really just have to keep this earth. However, we should treat the earth well, otherwise, the earth will not need us anymore. ”

Hao Qiuyan said with a ghostly eye, "Without whom, the earth still doesn't turn?" ”

The passenger plane landed at Nanyuan Airport, exited Lukou, and the two of them took a taxi to the National Aviation Administration, and came to the conference hall after boarding. There are a lot of people from the aerospace industry sitting here, many of whom are familiar with each other, shaking hands with each other.

The two of them looked for a seat, a familiar face stood up, and Hao Qiuyan hurriedly stepped forward: "Hello Uncle Wang." ”

Wang Fuchen was more cordial: "More than ten years have passed, and I can't imagine that your career is getting bigger and bigger, and you have become a base." ”

Hao Qiuyan: "It's all supported by the state. ”

The principal leaders of China's aerospace industry appeared on the rostrum, and during the meeting, they analyzed the affairs of the lunar base, and asked personnel from various fields to give specific explanations on the lunar base plan and then discuss it. Among other matters, the meeting lasted for two full days, with a thorough analysis of the pros and cons, and the announcement of a base at the South Pole and the establishment of an astronomical observatory on the far side of the Moon. An unmanned base will be built first, and robots will complete the work, and a manned base will be built gradually.

Before the meeting was over, the mobile phone vibrate, took it out and saw that it was Fu Yushu's phone, and hurriedly walked out of the conference room to the hall: "What's the matter?" ”

Fu Yushu's voice was urgent: "Mi Di's father is hospitalized, and his condition is very serious. ”

Midi is not there, they are the children of the old man, "Where are you now?" ”

"I'm in Nanjing."

"My meeting here is almost over, you will go from Nanjing to Harbin immediately; I was able to fly by plane, and after the meeting ended, I flew to Harbin to keep in touch. ”

The meeting ended the following morning.

The director of the space bureau left Hao Qiuyan and Zuo Haiyu behind to talk about the space agency's plan in detail. An astronomical observatory on the far side of the Moon, which [781] is responsible for receiving and processing signals from outer space, as well as electronic information on Earth. Originally, I wanted to change [781] to [Blu-ray Base], but I felt that it was inappropriate, the target was too big, and it should be low-key to the outside world, and the original name should remain unchanged.

Rushing to Harbin in a hurry, the two of them discussed ways outside the emergency ward of the hospital, and Fu Yushu shed tears: "My father-in-law has cerebral congestion and is still in a coma. ”

"Is there a danger to life?"

"It's hard to say now, listen to the doctor's opinion."

When he found the attending doctor, the doctor confessed: "Judging from the number of days in a coma, such patients will die of brain herniation or other comorbidities at any time, and they should be mentally prepared." ”

This is a path that is set in front of anyone and can do nothing but pray. Who hasn't had their loved ones robbed by death? This is an emotion that must be faced in life, and there is no choice.

Three days later, the old man died in his sleep, dealing with the aftermath with grief; The next thing to think about is Mi Jiatong's life and schooling. After discussion, it was agreed that the child would study in Nanjing; Hao Qiuyan prepared a house in Nanjing, and Mi Di's mother went to Nanjing to live with Fu Yushu.
