    Andreev knew that Li Zhuang was just a popular science person in the aerospace field and rarely bothered him. Even if Li Zhuang went to Xinwei City to watch the excitement, he basically did not introduce the detailed technical parameters to him and encountered information that he was interested in.  Email without exception.  The company's important research and development results related to security are recorded in the safety committee files, but the supervisors are often not serious, and the writing and style are messy. It is said to be a file, but in fact it is a weird collection of information.

    "Sending an email? Could it be related to the spaceship?" The computer expert asked the loudspeaker to display the information on the big screen. At first glance, it turned out to be information related to the spaceship, and the description was very detailed.  The research and development of the spacecraft code-named "ags-1" is the most important work of the asa aerospace vehicle research institute in the past three years, and it is progressing smoothly with the cooperation of multiple departments.

    What does ags mean?  In fact, it's quite simple. Asa's large spaceship; "1" refers to the first-generation large spaceship, a special vehicle designed for traveling between the moon and the earth.  Strictly speaking, it is a multi-functional spacecraft that operates between the permanent space station on the moon and the permanent space station on the earth. It is divided into manned spacecraft M series and unmanned cargo spacecraft C series.

    Andreev said at the beginning, "I used to think that the Russian people's idea of ??a big spaceship was a bit big, but I didn't expect ags to be even bigger!"

    Li Zhuang laughed when he saw this sentence. United Technologies has always done things like this, very grand, whether it is construction or research and development.  Trying to build a permanent base on the moon is just a dream.  The company's management has accumulated rich experience in large-scale project implementation, as long as the company is involved in the fields.

    The computer expert was a little surprised by the finished picture of the simulated space assembly given by Andreev. At first, he just thought that the large spacecraft with modular design could be easily assembled. He did not expect that the visual effect would be completely different, many times larger than imagined.  The finished product simulation includes the same-scale figure of Ji Chengjun, the first asa astronaut. His height is 180cm.

    "You can take a look at the attachment when you have time. It contains all the information about the ASA aircraft. I suggest you come to Xinwei City often to take a look. If you are not interested, you will be in big trouble." Andreev finished his business and joked.

    "Haha, do you still doubt my enthusiasm for human aerospace?" Li Zhuang giggled for a while, feeling that humans are really wonderful animals. Many people seem to have special abilities. I don't know if they come from the carbon-based network itself or from the carbon-based network itself.  Other unknown mysteries, such as ultra-frontier fields such as time and space and soul, such as intuition.  The research on time and space has reached a deadlock for the time being, and they are all assumptions and delusions; the soul is in darkness, but theology is prosperous; people have studied intuition for a long time, but there is still no systematic conclusion that can fully withstand scrutiny.  Animals have strong intuition, but special people among humans have stronger intuition. There are many weirdos at United Technologies, and Zhou Zhi is not a special case. There are many researchers who have similar abilities, but they are just stronger or weaker.

    The computer expert has less and less time to travel to Xinwei City because he is so busy. He has twelve children at home and a large number of smart homes.  The former needs enough time to get along with each other. He doesn't want to raise children like pigs, which is irresponsible and prone to situations that will make him unable to step down. The latter has absolutely no way, and subtle intelligent life cannot be ignored.  After the number of speakers reached 100, they were not produced again. The Vicky family, which had a higher performance, had 39 members and did not continue to increase, even if they could bring more convenience.

    "The national treasure is right. You can't get sick when doing research. It is estimated that only sociologists, not scientists and engineers, can still produce results by running around.  Ten years of getting along has made the company's management know that Li Zhuang is actually not interested in aerospace, but no one understands why he spares no effort to support asa.  ASA¡¯s expenditures are not as large as other forces imagined. The actual cost of the LTA space station, which is much larger than the International Space Station, is not far from that of the International Space Station. It is easy based on the company¡¯s manpower and material resources, because many researchers are voluntary labor, purely out of interest.  .

    He Xiuwen is very smart, but he is mediocre except for his own profession, which shows that being too greedy for anything other than professionalism will not lead to outstanding achievements. Li Zhuang has understood this truth very early.  The reason why he is still a popular science person in the complex field of aerospace, time is only one aspect, is because he understands his own personality and preferences, and is afraid that he will not be able to hold back.

    The computer expert thought for a while, opened the attachment of Andreev's email, and scanned it hastily. The information inside was detailed, but there was no core data, mainly for security reasons.

    The official name of "ags-1" has not yet been determined, but five unmanned lunar landing spacecraft called emea were launched for testing, which have the same configuration as the manned spacecraft.  EMEA is the main body of AGS. Li Zhuang feels that ASA management is very likely to name the first generation AGS mea11m and mea11c, because this is the most trouble-free and has a criminal record.  Other modules including nuclear power cabin, truss, carbon nanotube aluminum alloy connection channel, cargo warehouse and energy warehouse are all optional.  The mea11m manned spacecraft weighs about 300 tons when equipped with a nuclear power module and necessary options. The mea11c cargo spacecraft can weigh up to 80 tons.0 tons, and the load to and from the space station at the end of the month is about 300 tons.

    I don¡¯t know if the problem of laziness is caused by Li Zhuang or because there are too many similar people. Weizhou has a short history and the origin of the company¡¯s employees is complicated. It is difficult to choose a name that everyone agrees with, so I simply use letters and numbers instead. This is  A name that is acceptable to both asa and lower classes.

    emea consists of a power module, a command module, a rescue module, a lunar module and an additional section. It weighs approximately 150 tons and can carry six astronauts.  Even if something went wrong with the lunar module that landed on the lunar surface, the rescue module would have enough capability to pick them back up.  The Astronaut Center has only trained twenty astronauts so far, and human lives are precious.  These people have all been on the LTA space station and have rich experience. The fifty rookies who are still in training cannot compare with them.

    Emea has launched a total of five ships before and after, comprehensively testing the unmanned command module and power module, the unmanned lunar module and rescue module, the manned low-Earth orbit command and power module combined flight, the manned low-Earth orbit command and power module and landing  Subjects such as lunar module flight, full-system elliptical orbit flight around the Earth, full-system lunar orbit flight, and additional section-loaded power module flight.

    The emea spacecraft module adopts the earth orbit assembly scheme, which is launched by a rocket and then assembled into a complete spacecraft in earth orbit.  This is what the Apollo program wanted to do but was not capable of doing at the time. Advances in technology made it a reality.  The spacecraft can be made very large, and all five modules are equipped with power systems and sufficient margin. Even if an accident like Apollo 13 occurs again, the astronauts will not be in danger.  It is difficult to see the spectacular scene of tens of thousands of companies, more than 200 universities, more than 80 research institutes, and more than 400,000 people participating in it again. Technology has been advancing.

    The lunar module designed by asa is similar to the design scheme used by nasa last year. They are both thirty-ton spacecraft and use multiple ignition pulse solid rocket engines.  After dinitrogen tetroxide and undimethylhydrazine were banned, major countries have invested heavily in the research of solid rocket engines, and now they can meet the demand.  The upgraded lunar module will no longer impact the moon, but will become an integral part of the lunar space station together with the rescue module, taking full account of economy.  The descent stage is intended to be converted into a launch platform or construction robot for the construction of a lunar base.  Each emea unmanned spacecraft is equipped with three exploration robots, which are exploring suitable locations for base construction.

    The South Pole of the Moon, the Sea of ??Clouds, the Sea of ??Tranquility and the Sea of ??Moisture are all within the scope of exploration. The South Pole is the first choice. NASA explored it ten years ago, but did not release any valuable data.  The abundance of solar energy, mineral resources and geological conditions are the three priority factors. Whether enough water can be obtained from the moon is still unknown. The asa lunar base project team is designing a water circulation system to minimize the life and safety of astronauts.  Base factories depend on water.

    The Bathurst-class lunar probe orbiting the moon is equipped with 16 instruments including a neutron spectrometer, a stereo camera with a resolution of one meter, a gamma-ray spectrometer, and an x-ray spectrometer to detect water resources.  , landforms, mineral resources, lunar surface temperature and space environment, etc., a detailed lunar map is being drawn, and the fuel required for orbit change is obtained from the lunar space station.

    The five spacecrafts in the emea project docked with each other to form the prototype of the lta space station, killing two birds with one stone.  The core module, propulsion module, resource warehouse, multi-functional logistics warehouse, experimental module, living module and a wide variety of auxiliary equipment that were launched successively within two years together constitute the LTA space station.

    The International Space Station, which cost more than 100 billion US dollars to build, has far exceeded its design life. Even though RSA, NASA and JAXA tried their best to maintain it, it still sadly fell into the vast South Pacific six years ago.  During the subsequent international trade stalemate, although NASA and Jaxa were short of funds, they still independently built space stations.  NASA is based on the Space Assembly Factory, and Jaxa uses the same solution as CNNA, which is at the same level.  The problem with rsa is not big. Taking into account long-term development, Russia gritted its teeth and built a space station slightly smaller than Mir.  It is similar to esa, which was built and put into operation last year.

    Compared with these large-scale space stations, LTA has become the largest space building in human history, weighing about 1,200 tons, after accepting the node module, living module and experimental module of AEB and CNSA.  The CNNA originally had a space station, which was discontinued after reaching its design life the year before last. The new space station is still being designed.  There are many employees with dual nationalities in ASA, but CNSA did not regard itself as an outsider and went straight to Zhou Qisen and said that he wanted to be affiliated.  Li Zhuang considered that the attitude stabilization system of the space station could be adjusted, so he had no objection.  They moved very quickly there, carrying out four launches within a year, and the scheduled plan was successfully completed. The escape spacecraft used its own Shenzhou series, while AEB could only use vss because they did not have a mature spacecraft.

    Zhou Qisen talked with the director of CNNA when he visited Beijing last year. It seemed that there was no follow-up plan there and they were concentrating on designing spacecraft and developing advanced power systems.  When Zhou Qisen told Li Zhuang about this, he suspected that they were just talking and had no plans to build an independent space station; Li Zhuang believed that CNSA was interested in LTA's living facilities because CSA was also greedy and was negotiating with ASA.

    ? ?The ??lta space station is a new version of the International Space Station, and we seem to be at a disadvantage.  "Andreev once complained at a high-level joint meeting, and Li Zhuang replied, "To suffer a loss is to take advantage," which puzzled him.

    "Andreev is very interesting, but ASA is essentially an international organization. Our researchers and astronauts don't know which country they belong to." Li Zhuang thought of the old story and had a headache.

    Many asa researchers retain their original nationality, and the astronauts are even more diverse.  There are seven Chinese people, which is similar to the company¡¯s talent structure, and five of them have Chinese nationality.  Among other astronauts, many have dual nationality, including France, Germany, the United Kingdom, Brazil, Canada, Russia and Citigroup, all related to their origin and nationality.  With the increasing development of communication technology and international trade, international exchanges have significantly increased. In addition to Japan, more than 100 countries, including Russia, recognize dual nationality.  Little Japan is now hardened, and according to reports from the Second Office, it is very likely to join this ranks.  Dual nationality is a double-edged sword. Japan is also a big exporter of immigrants. It used to be timid, but now that Citigroup's power has been greatly reduced, they probably want to show off.

    The aerospace field is relatively sensitive, and it is difficult for other organizations to encounter the trouble caused by multiple nationalities, but United Technologies cannot, because its members are complex.  When Ji Chengjun went to space on the vss spacecraft five years ago, the Australian media said "we have achieved a historical breakthrough"; some Chinese media were abusive, some were proud, and some were humorous.  The Canadian media didn¡¯t pay much attention, and mostly just ignored it. Because the company has a good relationship with Canada and has frequent business contacts, some media humorously said, ¡°We Canadians have entered space again!¡±

    In the past seven years, asa's launches have been very frequent, and its level has rapidly increased to the level of nasa, surpassing the established aerospace powers.  In this case, the issue of the astronauts' nationality became serious, and the media ridiculed it frequently.

    "Oh, forget it, this is not an issue that I should be concerned about. Let those who should be in charge deal with it." The computer expert rubbed his forehead and continued to read the information.

    The vss spacecraft is the first spacecraft to be developed. It consists of a propulsion module, a return module/cargo compartment and an orbital module, with a modular design.  The spacecraft is 11 meters long, weighs about 12.5 tons, and can carry four astronauts.  The escape spacecraft used on the LTA space station is generally a propulsion module plus a return module, code-named vss-1m.  The cargo spacecraft combination used in the initial stage was the propulsion module, orbital module and cargo warehouse, code-named vss-1c, with a load capacity of five tons. After the aerospace plane was put into use, the vss-1c was idle, mainly because it was not as economical as the aerospace plane.  The load capacity is only one-quarter of the VA level.

    The space shuttle has had many accidents, and the operating conditions of the aerospace plane are more complicated than that of the space shuttle, so accidents are inevitable. Therefore, asa rarely uses aerospace planes to carry people, and mainly uses vss.  NASA attaches great importance to the astronaut life support system and does not care about spending more money for it. The media has received rave reviews. NASA was forced to adopt a similar solution under the pressure of public opinion.

    "I'm really looking forward to the launch site next month. We started too late, and the top five places to land on the moon have been taken up. But I hope that asa can win the honor of being the first human to build a lunar base." Li Zhuang was fascinated, NASA, cnsa,  Jaxa, RSA and ESA have all carried people to the moon. Asa, which was founded the latest, has to watch the backs of the big brothers. Fortunately, the good land of the moon has not been diluted.
