The Russian Space Agency's spacecraft Soyuz has landed safely on the steppes of Kazakhstan, after Russia has a relevant commitment, will return to Earth with American astronauts, Russia did not be embarrassed by the international situation in space astronauts, generously sent American astronauts home.
Russia's decision to return with American astronauts is a show of goodwill, and it is unclear how Russia will react if the United States and other countries continue to impose sanctions on Russia. In this international dispute, the biggest focus is not the destination of the astronauts, but the end of the space station.
The International Space Station was built by the United States and Russia, and more than a dozen of them participated one after another, but the only two major powers that can really determine the fate of the space station are the United States and Russia. In fact, the space station has been in operation for 24 years, according to the original plan of the space station, the original space station should have retired, but subsequent countries have repaired the space station, extending the service life to about 2030.
The cost of repairing the space station every year is as high as hundreds of millions of dollars, even so, the significance of the space station is still not comparable to hundreds of millions of dollars, there are a large number of scientific research work and so on need to use the space station, may be a slightly larger scientific research project value of hundreds of millions of dollars, not to mention all scientific research projects, comprehensive comparison, maintenance costs are only a small expenditure, which is why the country is willing to spend money and do not want the space station to retire. Why are so many scientists worried about the future of the space station?
Because of the first construction of the space station, Russia played a very important role, of which the space station's power module is from Russia's Zvezda, if there is no Russian power capsule, then the space station has only one end, that is, the fall. Russia doesn't need to separate the power capsule, just don't provide power, and the space station will become very dangerous.
According to scientists' calculations, the space station will drop by an average of about 2 kilometers per month due to the influence of drag, so the space station needs power to maintain its height at all times, and the cost of power sources alone is as high as 200 million US dollars per year, this work has always been the responsibility of Russia, and only Russia can be responsible.
The Russian Space Agency was interviewed by the media, and in the process of the interview, the problem of the space station itself was also raised, because the International Space Station itself has various problems, even if it is repaired, it is difficult to solve these problems, and it is expected that the space station can only work for about five years, far less than the previously expected ten years.
The head of the space agency also said that Russia has plans to build an independent space station, which is expected to be implemented from 2026. The International Space Station has advantages and disadvantages, the advantage is that countries jointly establish a space station, which can achieve certain interoperability in technology, and in terms of scientific research projects, several countries can cooperate together to communicate in depth, which are obvious benefits.
Then the International Space Station also has its bad points, the most critical point is that when countries have disputes, the space station will fall into an embarrassing situation, and it is likely to cause a situation of "separation", which is another obstacle to scientific research work. If a country can choose, it should choose an independent space station, as long as it has its own space station, it can take a cooperative approach in the project and fully grasp the initiative, which is why the mainland should vigorously develop the space station.
We all hope that all countries can coexist peacefully, develop science and technology together, and make progress together, which is the prerequisite for human progress. The mainland has always maintained the concept of harmonious coexistence, and the space station independently built by the mainland is gradually improving, and one day astronauts from other countries will visit and progress together.
Here is the Science Observatory, pay attention to me I do not get lost, will continue to update some scientific knowledge!
