Yang Liwei, member of the National Committee of the Chinese people's Political Consultative Conference and deputy chief designer of China's manned space project, said in a recent media interview that the entry of ordinary people into China's space station is not a technical problem, but mainly depends on the demand. In addition, countries have applied for joint flights of astronauts, and China has also reserved international cooperation resources in engineering, ranging from experiments to cabin level cooperation, China's manned spaceflight is open to different countries and institutions. Yang Liwei said that the on orbit rotation of Shenzhou 14 and Shenzhou 15 astronauts is a verification of the carrying capacity of the space station. After the completion of the Chinese space station, the on orbit residence time of astronauts will be designed according to the needs. At present, according to international practice, half a year is a normalized residence cycle, and the on orbit time may be extended according to the needs of work and experiment. In order to ensure the astronauts' long-term on orbit life, Yang Liwei said that in terms of diet, the types of food will be adjusted according to the astronauts' personal taste and flight time, such as transporting the astronauts' favorite fruits with a long storage cycle. For whether ordinary people can enter the space station in the future, Yang Liwei pointed out that it is not a technical problem, but mainly depends on the demand. "As long as there is demand and resources allow, this is not a very long-term problem." With regard to the selection of astronauts, Yang Liwei said that a group of astronauts will be selected at a certain interval according to the needs of the mission. At present, the selection of the next group of astronauts is being considered, not only to increase fresh blood, but also to form a good knowledge structure and age batch, and realize a virtuous circle to meet the needs of the mission. He also pointed out that the training time of astronauts of different natures is also different. For example, it may take about three and a half years for pilots and two and a half years for load experts. Corresponding training programs should be formulated according to the work needs of different natures. Yang Liwei said that China's space station considered international cooperation at the beginning of its design. Now many countries have applied to China for training astronauts and joint flight. China has set aside resources for cooperation in large-scale projects and international trade fairs in the future. "Our country's manned spaceflight is open to different countries and institutions." Yang Liwei said that China has carried out a number of space science experiment cooperation projects with foreign companies, and there will be other experimental cooperation in the future, and even foreign astronauts will fly together.
