16 countries 'capital contribution' to set up an International Space Station

After 4 years of interruption, recently, the plan to establish an international space-cooperation station of 16 countries with an estimated investment of up to 50 billion USD has been restored!

In early March of this year, 16 member countries building the international space station (ICG) agreed that the station construction will be restored after 4 years of interruption.

International payment is a cooperation of 16 countries including the US, Russia, France, Germany, Italy, England, Belgium, Denmark, Netherlands, Norway, Spain, Sweden, Switzerland, Japan, Canada and Brazil.

International payment account is expected to be invested with a huge amount of 50 billion USD.

Among them, US research costs are 27.6 billion USD; Russia: 3 billion USD; European Bureau of Aeronautics (HKVT) is $ 3.6 billion; Japan 3.5 billion USD; Canada is $ 1 billion and the cost of installation in orbit is $ 11 billion.

International space station.

The basic structure of TKGQT is a bearing frame with a length of over 100m, they will join many compartments and equipment on the bearing frame.

After completion, TKGQT will last 10-15 years, total weight of the station is 423 tons, length of 108m, width of 88m and area of ​​only two small football fields. The turbocharger compartment is only equal to the passenger compartment volume of two 747 jets, where there is enough room for six long-term travelers

The international payment system will operate at a height of 400km, on a tilting trajectory of 51.60, at this height the air resistance will cause the space station to gradually lower the altitude, so it must use the airship every 90 days Transport or aviation aircraft lift the space station back to its original height.

The construction of international payment is divided into three phases. The first is the preparation phase (1994-1998), mainly to bring American astronauts to work at Hoa Binh space station, to train the working and living capabilities of American travelers on the station. time.

Second is the installation phase (1998-2001), mainly installing the main part of the international payment system, so that the space station can bear the load of 3 people.

Third is the final installation phase and application (2002-2010), mainly completing the installation of the station to achieve the requirement of 6-7 people working long-term on orbit.

Since this is a large-scale aeronautical project, every aspect of installation, management, engineering and cost faces a major challenge, so the previous station construction time is expected to be completed. became in 2003, but must last until 2010.

With the current scale, it is very difficult to monitor the station from the ground, because when starting the installation on orbit, there are some details that still have to be built, so it can only be installed and tested. . Especially the software is provided from hundreds of manufacturers in 16 countries, so it is easy to be influenced by each other.

Recently, what makes the member stations of space station headaches is, just a major component that is not launched into orbit on time will also affect the progress of the whole plan.

In fact, there was a time when Russia's service compartment had failed to keep up with the time limit, which made the plan to go back 1 year; or after the Colombian incident, this work must also be stopped for several years; The long-term survey team from 3 people must be reduced to 2 people to save energy provided to the station.

Even when the station is completed, the operation management is not easy, each astronaut needs to be provided 658kg of food, 209kg of clothing and other personal items. Currently, the cost to bring 1kg of objects to the space station needs 2.2 thousand USD, so to maintain the space station, each year it needs to spend 1.3 billion USD.
