There are currently 17 countries that have cooperation intentions with the Chinese Space Station and have signed agreements, including Japan.
I looked at the second phase of the development plan for the China Space Station (Tiangong Space Station). The backup core module and experimental module can be used for proper transformation, and international cooperation should be carried out as much as possible to expand into the International Space Station.
1. The second core module is still completely built and launched and operated by China;
2. Experimental module ③, mainly in cooperation with the European Space Agency. China provides services such as the experimental module body, power supply, communication and launch, and the European Space Agency countries are responsible for internal experimental devices;
3. Experimental cabin ④, mainly in cooperation with the third world (including Japan, India, Pakistan, Brazil and other countries). China provides the experimental cabin body, power supply, communication and launch services, and each country is responsible for the internal experimental equipment;
4. The seventh cabin, the Russian cabin, is all independently built, launched and operated by Russia, and reserves the docking interface with the Russian spacecraft;
At present, 9 scientific research projects from 17 countries have been successfully selected into the first batch of cooperation lists for the Tiangong Space Station. We provide free uplink transportation services for these scientific research projects and provide on-orbit space experiment sites, but the scientific research data obtained at the same time must be unconditional Share with us.
