Grow vegetables on the space station, develop unique new materials, find new physical laws, and explore how human beings can survive in space for a long time. With the completion of the Chinese space station this year, a large number of cutting-edge scientific experiments will be carried out in the "Tiangong" one after another.

The Chinese space station has made long-term and systematic planning in four important fields: space life science and human body research, microgravity physical science, space astronomy and earth science, and new space technology and applications. It has developed a large number of scientific research facilities and supported more than 1000 research projects in orbit.

China also actively carries out international cooperation on the space station. For example, China has cooperated with the United Nations Space Agency to solicit scientific research projects from scientists all over the world. The first batch of nine international cooperation projects have been selected. In the future, China will solicit proposals for new projects from the world every two to three years.
