Space station, also known as space station, space station, orbital station. It is a kind of manned spacecraft that operates in low earth orbit for a long time and can be used by many astronauts to visit, work and live for a long time. There are two types of space stations: single and combined. A single space station can be launched into orbit by a space launch vehicle at one time, while a combined space station is assembled in space by a space launch vehicle that sends components into orbit in batches.

The basic composition of the space station is a manned living module as the main body, plus modules with different purposes, such as the working real cabin, the scientific instrument module, etc.

As early as the year, the Soviet Union launched the first space station of mankind, Salyut One. After that, the Soviet Union and the United States launched several space stations one after another. There are two well-known ones: "One is the Mir space station launched by Nianhu before the collapse of the Soviet Union.; "It's the International Space Station." The former is famous because of its fateful fate, as the last space station launched by the Soviet Union, and Russia, as the successor of the Soviet Union, in the last few years of the last century, tried several times to extend the life of this space station, which was designed to last only ten years. During that time, the world's media was flooded with news reports about the Mir space station, and every once in a while, Russia would say that Russia had found the funds to repair the Mir space station and extend its service life.

However, in this way, the Mir space station held out until the end of the year, and the Russian space agency could no longer raise funds, and was forced to decide to crash the Mir space station. Finally, on March 23, 200, it crashed into the Earth's atmosphere, and the debris fell into the South Pacific Sea.

The crash of the Mir space station was not due to technical reasons, but was actually a suppressive measure by Western countries against Russia, because at that time, there was already another space station in the sky, that is, the International Space Station.

Naturally, Western countries do not want Russia to have a space station of their own.

Speaking of the International Space Station, it is also very famous.

The idea of the International Space Station was first proposed by US President Ronald Reagan, and after nearly ten years of exploration and many redesigns, it was not until the collapse of the Soviet Union and Russia's joining that the International Space Station was completed and implemented in three years.

The space station is led by the United States, Russia, Canada, Japan, Brazil and ESA. Belgium, Denmark, France, Germany, the United Kingdom, Italy, the Netherlands, Spain, Sweden, Switzerland and Ireland are among the official member states. Its design life is the heart of the year, the total mass is about a ton long, the width of the wingspan is meters, and the operating track height is a kilometer. The atmospheric pressure in the manned cabin is the same as that of the ground surface and can carry 6 people. The structure of the International Space Station is complex and large-scale, consisting of astronaut living module, real cabin, service module, docking transition module, analysis frame, solar cells and other parts.

The International Space Station does not seem to have the word "international", but it is not really international in nature. Since the completion of the National Space Station, in addition to the countries involved in the development of the International Space Station have sent astronauts to land on the International Space Station, other countries such as Israel and Saudi Arabia that have particularly good relations with the United States have also selected personnel to work and live on the International Space Station for a period of time.

However, as a major aerospace country, Huaxia has launched the Shenzhou spacecraft successively and successfully realized the manned space project. But the gates of the International Space Station have never been open to China. After the first astronaut from China completed the mission of space flight, the astronauts of the International Space Station once issued an appeal to invite the astronauts of Huaxia to land on the International Space Station. But astronauts are only astronauts after all, and it is not they who dominate the ISS, but politicians. The astronauts' appeal naturally sank into the sea, and there was no follow-up.

The space station cost a huge amount, the Soviet Union's Mir space station, cost 3.5 billion rubles, the International Space Station budget is 50 billion US dollars, and by the time the International Space Station is basically completed, many countries involved in the construction have spent a total of 100 billion US dollars, and the annual operating expenses of the International Space Station are as high as 90 billion US dollars. Maintaining a space station is almost the same as filling a bottomless pit with money, and it is the kind that can never be filled.

Although the scale of the Tiantian No. 1 space station is relatively large, with these two space stations as a reference, you can probably estimate how much it will cost. Huaxia's decision to build its own space station was also a helpless move. If possible, Huaxia naturally hopes to join the plan of the International Space Station, but as an excluded member, Huaxia, who has a lot of money, cannot enter the door and can only start a new stove.

An empty station is very expensive, but its value in the field of scientific research is irreplaceable, and as a permanent base in space, the space station can do things that astronauts of old and spacecraft cannot do. More importantly, the station is an indispensable part of the future Sky Factory, Space City, Space Migration, etc. In addition, the space station also has a huge military value, once China and other countries have a war similar to the eight-year war of resistance, then the space station will become a huge deterrent force hanging over the enemy's head, which can directly destroy or recover the enemy's satellites from space, and directly strike at the enemy from space.

If the space station is not built, it is possible to be in a passive backward position in the future competition for space resources, and if it is backward, it will be beaten and bullied.

Liu Shiqing circled around the Sky No. 1 space station model several times, "General Hong, how is the current operation of our space station?"

Hong Dalei smiled: "Okay, very good." Since we started building the space station, the attitude of the Americans, who have always been reluctant to join the ISS, has eased a lot. We are also approached by many countries asking for cooperation on the space station. It can be said that with the Sky No. 1 space station, we have more and more weighty say in the aerospace field, especially in the field of space technology

Ye Qiuyan said: "Mr. Liu, this is the model, just look at it twice." Let's go, we have more important things to do. If you like the model of the Sky 1 space station, I will ask someone to send you a set of miniature models, not to mention the Sky 1 space station, even the model of the Long March series of rockets, the model of the Shenzhou spacecraft, the model of the Marrying Satellite, and the Firefly probe, I will let someone send you a complete set. ”

The aunt satellite is the general name of the Huaxia lunar exploration satellite, and the firefly probe is a probe for Mars that Huaxia has implemented since its own efforts.

The model is not a real satellite, the cost is only a few hundred yuan, and the better one is a few thousand yuan, for Liu Shiqing, who has contributed a complete set of technical information for the space plane, not to mention only sending a few ordinary models, even if these models are all made of gold, it is far from enough to compare with the value of the entire set of technical data.

Liu Shiqing did not refuse Ye Qiuyan's gift, he really wanted such a set of models, even if they were not placed in his office and placed in the library of Galaxy School, they could also stimulate the patriotic enthusiasm of the students on a large scale. These models can play a role that the teacher may not be able to play in a thousand or ten thousand sentences.

"Mr. Liu, Director Guo, Secretary Yang, let's go, Ye Qiuyan persuaded.

Liu Shiqing took one last look at the model of the Sky No. 1 space station, and then followed Hong Dalei, Ye Qiuyan and others around the model and continued to walk forward. Instead of going up the stairs or taking the elevator, they walked straight through the first-floor lobby of the office building, exited through the back door, and walked on.

Not long after, the group walked forward and arrived at the scientific research building of the Institute of Space Technology. The Institute of Space Technology can be said to be the one with the highest average academic qualifications among all scientific research units in China, with as many as 11 academicians of the Chinese Academy of Sciences and the Chinese Academy of Sciences, and more than 300 doctoral supervisors and master's supervisors.

If Galaxy Industry has such a strong team of technical talents, it must be crazy. However, after all, the development time of Galaxy Industry is too short, and compared with the space technology research institute supported by the state, it is too poor in this regard.

Not far from the scientific research building is the factory of the Institute of Space Technology, which usually manufactures rockets and satellites according to the needs of the country, and then transports the manufactured rockets, satellites and other materials to the rocket launch site for final hoisting and then selects the opportunity to launch them.

Liu Shiqing and others followed Hong Dalei and Ye Qiuyan to the assembly workshop of the factory. As soon as you enter the door, you will see a huge, complex engine in the middle of the workshop, which is very eye-catching. Around the engine, a cordon was pulled, and several armed police fighters, armed with guns, stood guard beside them.

Seeing Hong Dalei and Liu Shiqing and them enter the workshop, someone hurriedly stopped them, Hong Dalei, Ye Qiuyan and others showed their documents in accordance with the regulations, and explained the instructions of Liu Shiqing and others, and the other party let them go. After hearing the news, the chief engineer of the Space Technology Research Institute rushed over and accompanied him throughout the whole process.

"Mr. Liu, do you see it? This engine is based on the information you provided. With the approval of the Central Military Commission, we decided to name this model of engine "Galaxy" to commemorate your contribution in this area. Ye Qiuyan stared at the Galaxy Engine with some obsession, the affection in his eyes was so affectionate that he was afraid that his wife would be jealous when she saw it.

Thanks to "Black Moon, I am a cloud in the sky" and "gone with the wind". Tips, thank you D
