The reporter learned from the Space Application Engineering and Technology Center of the Chinese Academy of Sciences that the scientific experiment facilities of the China Space Station have basically completed the on orbit test recently, and the on orbit operation is stable and reliable, with the ability to carry out large-scale space science research. As of August 18th, the space station has conducted more than 60 experimental projects and tens of thousands of in orbit experiments, obtaining nearly 60TB of original experimental data and more than 300 scientific experimental samples. At present, scientists are conducting ground research on experimental samples, and some projects have achieved important results. Wang Qiang, Deputy Commander in Chief of the Space Application System of the Manned Space Project and Deputy Director of the Space Application Engineering and Technology Center of the Chinese Academy of Sciences, said at the briefing on the space application and development of the Manned Space Project, in the field of space life science, Chinese scientists achieved the induction and differentiation of human embryonic stem cells into primordial germ cells, spermatogonia and follicle like cells on the space station for the first time, Systematically answering the impact of space microgravity environment on stem cell lineage differentiation, and developing systems and devices for in vitro differentiation of multiple types of germ cells, with the potential to promote technological innovation in assisted reproductive therapy for infertility; In the field of space materials science, scientists have discovered the rapid eutectic growth mechanism of niobium silicon alloy, laying the strength and technical foundation for the development of the next generation of high-performance niobium alloy materials for aircraft use. He said that "shipbuilding is for station building and station building is for application". At the beginning of the manned space project, a special space application system was established, which was led by the Chinese Academy of Sciences. In the first and second steps of manned space engineering, more than 600 sets of payloads were newly developed, and more than 60 space science and application missions were carried out, achieving a number of international and domestic groundbreaking achievements, promoting the overall leap in China's space science and application level. It is reported that the manned space engineering space application system has widely solicited space station science, technology, and application requirements for space application systems in universities, research institutes, and industries across the country. More than 50 academicians and nearly a thousand top domestic and foreign scientists have been organized to conduct in-depth research and demonstration, forming a systematic and systematic space station application and development engineering application task plan. The plan includes four major fields, including space life science and human body research, microgravity physics science, space astronomy and earth science, new space technologies and applications, and 32 research themes. It is expected to implement 65 research plans and thousands of research projects. Wang Qiang said: The construction and operation of space stations is a historical opportunity to promote the development of space science and applications in China. In accordance with the overall goal of building a national space laboratory and the strategic needs of national scientific and technological development and economic and social construction, we will demonstrate and select application and experimental projects with international advanced level, significant scientific and technological value, and significant strategic application potential, in order to contribute to high-level scientific and technological self-reliance, national economic construction, and social development Make greater contributions (New News Agency)
