Why don't other countries want to rebuild the expiring International Space Station?

Since the rapid exploration of space in the last century, our exploration of space has never stopped. At present, we are not only satisfied with the sky above the earth, but also will set foot on the moon, March into Mars, and even carry out the space migration plan in the future. Humans cannot live on the earth forever. After all, our goal is the sea of stars. Facing these goals, the space station is particularly important.

As the largest object in orbit in the world at present? The International Space Station was jointly established by the Russian Federal Space Agency, the National Aeronautics and Space Administration of the United States, the Japan Aerospace Exploration Agency, the European Space Agency, the Canadian National Space Agency and the Brazilian Space Agency from 1998 to 20 10.

The existing International Space Station is expected to be retired in 2024, only four years from this year. According to the published plan, the International Space Station in China is expected to be completed around 2022, which means that China will become the only country with a space station after the International Space Station is retired in 2024.

Seeing this, many people may be curious. Why didn't other countries build the International Space Station after it was retired? Why is this? Is it because there is no strength? No, at the end of last century, western countries have already started to build space stations. According to the truth, don't they have the experience to build another one? Why do they all choose to quit?

First, we need to know how much it costs to build the International Space Station. According to the estimate of $654.38+000 billion when the International Space Station was established, the actual cost of waiting for the operation of the space station far exceeded expectations, reaching as high as $500 billion, which does not include other expenses such as post-maintenance. It can be said that the establishment of the space station is a money-burning project.

At present, the International Space Station has been established by many countries, but the contradictions among many big countries have become increasingly prominent. Many countries have many differences in the construction of the International Space Station. Some countries want to get rid of American control and explore their own universe.

Although the space station has an effect on space exploration, it has little impact on people's livelihood, because the current space station is mainly used to explore space and cultivate seeds, and there is no way to bring practical benefits, which is why many countries are reluctant to build another one.

Nowadays, the focus of human space research has gradually shifted, and the space station, as a former space research and development, has given way to more ambitious exploration of Mars. Next, humans will not only explore Mars in an all-round way, land on Mars, but may even immigrate to Mars.

In recent years, China's economy has developed rapidly, and our space exploration has gradually accelerated. The establishment of a space station is also a step in our space exploration, and the exploration of Mars is also a development goal.
