BEIJING, April 24 (Xinhua) -- Science facilities on China's planned Tiangong space station could support hundreds of space research projects after it's completed in 2022.

Sixteen experiment racks will be installed in the core module and two lab capsules of the space station, and an extravehicular experiment platform will be built.

Each rack is regarded as a lab that can support various space experiments, and astronauts can upgrade and replace the facilities.

In addition, a capsule holding a large optical telescope will fly in the same orbit as the station, according to the Technology and Engineering Center for Space Utilization (CSU) of the Chinese Academy of Sciences.

The facilities will support a large number of research projects in fields such as astronomy, space life science, biotechnology, microgravity basic physics and space materials science.

China is seeking international collaboration in experiments on the station to promote sustainable global development and cooperation.

Almost 100 international cooperation proposals have been received, and about 30 have passed the initial evaluation, said Zhang Wei, director of the Utilization Development Center of CSU.
