"Five...Four...Three...Two...One...One... Launch!"
Accompanied by the command from Jiuquan Satellite Launch Center , the Long March 2 F Yao-14 carrier rocket slowly took off with the Shenzhou 14 spacecraft in a roar.
After 577 seconds of flight, the Shenzhou 14 spacecraft separated from the carrier rocket and successfully entered the predetermined orbit.
This marks the success of the 23rd mission of my country's manned space project, and also indicates that the construction of space station in my country will "take it to the next level"-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
But the United States is the opposite of our country. Today, NASA even needs to ask Russia for help when landing on the space station, which makes people feel a bit magical.
However, this is the case, and the reason for all this starts with the "space station" itself. The construction of the
space station: the process of building blocks
space station construction can be traced back to the 1980s, that is, the "Salute 1" space station launched by the Soviet Union in 1971.
"Salute No. 1" space station is about 12 meters long and has a maximum diameter of only 4 meters. It is this size, but it is already the sum of the orbital cabin, living cabin and docking cabin. Compared with today's various space stations, it can be said to be a small and cute "mini station".
However, it is this "little cute" that is cross-generational in the aerospace field. The Soviet Union also developed and launched the second-generation space stations of Sailor 2 to 7 on the basis of Sailor 1 , making the Soviet Union the "vanguard" of aerospace research at that time.
The United States, which confronted the Soviet Union, regarded this behavior as part of the battle for hegemony, invested heavily in researching space station , and in 1973, it completed the launch of the Space Laboratory space station.
This move by the United States also pushed the "space Cold War" to a new peak. In order to win this war zone, the Soviet Union increased its research on space stations, and the results achieved were also impressive, such as the launch of the third-generation space station " Mir ", the connection of the "Quantum 1" astronomical cabin, the connection of the "Quantum 2" service cabin, etc.
The Soviet Union's construction of space station was like building blocks, and it improved the space station bit by bit.
Although this sounds a bit joking, the Soviet Union's construction of the space station made the United States feel "out of reach". The US authorities began to be pessimistic about catching up with the Soviet Union, and the research on the space station was also in a dilemma.
However, the research on the space station is the concept of "you get what you pay for" after all, and with such endless research investment, the Soviet Union was really difficult to support.
Finally, under the influence of many factors, the Soviet Union also moved towards the understanding of the building blocks.
As the successor of the Soviet Union, Russia seemed a little lonely for such a huge scientific research project, so the renewal project of the space station was forced to stagnate, and the research of the entire space station was once suspended.
However, what the Russians never expected was that their old rival, the United States, was also in trouble in this matter.
It turned out that after The Soviet Union collapsed , the United States resumed the construction project of the space station, but several meetings and discussions failed to solve the funding problem.
Although Clinton agreed to the implementation of the project, the premise of "restricting funds" made the US Space Administration very embarrassed, like a clever woman's "cook without rice".
Under this dilemma, the United States and Russia chose " to join forces to keep warm ", that is, jointly conducting research on the "Alpha" space station. The specific division of labor is the model of "Russia produces technology and the United States produces funds".
With the lead of two "big brothers", Japan and European countries have also joined the project, making the "Alpha" the first international space station.
However, the United States has been in trouble with the arrival of the station, and even developed to the point where it can only enter the Alpha through Russian spacecraft. What exactly happened?
The United States buys seats from Russia: The helplessness of being hidden
The matter of buying "ship tickets" from Russia is actually the unspeakable hidden tide of the United States.
Before 2011, the United States had been relying on the space shuttle to transport astronauts entering the space station. However, with the "accident" of the Challenger space shuttle , the US authorities began to doubt the reliability of the space shuttle.
It is important to know that the price of training a astronaut is very high, and manufacturing a space shuttle is even more expensive. This means that once something happens to the space shuttle, the United States will face the "pain of cutting flesh".
Under such circumstances, NASA is worried every time he uses the space shuttle to carry people. Finally, with the landing of the "Atlantis" in 2011, the history of the US space shuttle manned also "landed" accordingly--stop the space shuttle manned.
can ground the manned space shuttle, and the US authorities are facing a situation of "no ship to sit", and the United States has no choice but to find Russia. This is mainly because Russia's manned technology is very mature and it is not easy to cause "planes are destroyed and people are killed".
However, how could Russia let go of the United States with its bowed head?
The Russian authorities directly offered a price of $90 million per ticket. The United States was so angry that it gritted its teeth, but the manned technology was indeed immature. If a space shuttle accident occurred again, it would be difficult to deal with ten "90 million" at that time.
So the United States should pay this price, and this purchase has bought nearly 70 copies in recent years, generating nearly 4 billion US dollars in revenue for Russia Space Administration .
However, money is still a small matter to the United States. The key problem is that after being subject to Russia, the United States can only give in in international confrontations, which makes the US government feel aggrieved. However, the funds for research on manned technology are really tight and it is difficult to make a breakthrough.
So, NASA immediately launched support for commercial space manned vehicles, attempting to complete the research and development of manned technology through commercial forms, among which Musk's SpaceX company is the most prominent.
SpaceX does not disappoint the "beautiful hope". With the support of huge funds, it has developed a manned version of the "Dragon" spacecraft , and successfully carried two NASA astronauts to the International Space Station , completing the "zero breakthrough" of the United States after 2011.
However, Musk is a businessman after all, and his profits are very small and even reaching a "zero" profit, so SpaceX immediately announced that it will be preparing to stop production of the "Dragon" spacecraft. The news of
directly pulled the US authorities from heaven to hell. Faced with SpaceX's sky-high conditions, the United States would rather go back and buy Russian ship tickets.
This also triggered the wonder of "the United States imposes sanctions on Russia, except for NASA's space station". In the final analysis, it is just the security and helplessness of the United States and the "disaster" caused by this International Space Station.
is written at the end (summary)
However, the internationality of the Alpha number is also chosen, for example, China is a country excluded from the "international".
The US authorities have completed a comprehensive blockade of my country's aerospace through a " Wolf clause ". Not only is it difficult to develop aerospace technology and materials, but China is prohibited from participating in the research on space stations.
The United States' approach made my country deeply understand the importance of "self-improvement". With this determination to work hard and the unremitting efforts of aerospace scientists, my country finally launched its own space station in 2011------Tiangong. After
, my country followed the Soviet model of building blocks and successively built core cabin "Tianhe" for the Tiangong, "Wentian" for the No. 1 experimental cabin, "Dongtian" for the No. 2 experimental cabin, and so on.
With this development, Tiangong has gradually gained the strength to "compete" with Alpha.
Now Shenzhou 14 is carrying out the construction mission of the "Space Laboratory". If the project can be completed smoothly, Tiangong may complete the overtake of the "International Space Station".
Listening to the roar of the rocket like a dragon, the world will finally understand: the giant dragon entrenched in the east is awakening little by little.
