As soon as this topic appeared, the United States thought of the blockade of China and the technical oppression of China. Now this measure makes the United States feel that the United States can build an independent space station like it doesn't need the United States. Has a powerful cosmic force. Of course, as far as it is concerned, today's International Space Station is not in China. It is reported that everyone said that China was "refused to join the International Space Station", but in fact, according to public reports, China was not refused, but did not actually apply, so there may be some misunderstandings here.

But this time the Chinese space station rejected the United States, that's for sure. Of course, there is also a reason for rejecting the United States this time. It's not that we don't want the United States to enter the space station in China, but that the projects that the American team participated in the declaration failed to meet the standards set by China in scientific value and technology. In other words, the "scientific project" of the United States does not meet the standards set by our country, so we hereby reject whether the United States will change the project in the future actual operation. After the Long March V-B carrier rocket developed by China successfully carried a new generation of manned spacecraft test ship, the orbit construction task of China's space station laid an important foundation. What we have to do now is to prepare for the construction task. According to public information, China will complete its orbit construction plan around 2022 to prepare for the long-term stability of the subsequent space station, so the time for successful construction planning is getting closer and closer.

The "International Space Station" will be jointly built by multinational companies, with unprecedented technology and scale, and will become the largest and most complex spacecraft for many years. By participating in the construction of the International Space Station, several countries of the European Space Agency and Japan have carried out large-scale space experiments, mastered a large number of manned space technology through selective development, and reached the world advanced level in related fields. For various reasons, China did not participate in the International Space Station, and China should build its own space station. These development routes are different from cost comparison (the ratio of input cost to production income), but after the completion of the space station, it will have completely independent manned space flight capability, laying a better foundation for the subsequent development of the space industry.

In the third stage of manned space strategy, China has broken through the first stage manned spacecraft launch and the second stage rendezvous and docking technology, and is developing the next stage space laboratory. The launched "Tiangong-1" target aircraft is mainly used for rendezvous and docking experiments, but some space experiments will also be carried out to accumulate experience for the operation of the space laboratory. After the completion of China Space Station, it will fully master manned space technology and conduct large-scale space experiments, thus writing a more brilliant page for China's space flight.
