China News Service, Hainan Wenchang, July 24th (Ma Shuaisha and Sun Zifa) Wentian experimental module was successfully launched on the 24th.
Zhang Wei, a researcher at the Space Application Center of the Chinese Academy of Sciences and director of the Application Development Center, said in an interview with the media recently that the China Space Station will carry out four major research projects, including space life science and human body research, microgravity physics science, space astronomy and earth science, and space new technology and applications. 65 research programs in the field, including nearly a thousand research projects.
At 14:22 on July 24, 2022, Beijing time, the Long March 5B Yaosan carrier rocket carrying the Wentian experimental module was ignited and launched at the Wenchang Space Launch Site in my country, and the launch was a complete success.

After the construction of the Chinese space station is completed, it will operate in orbit for more than ten years.
It is known that the space station has developed advanced scientific experimental cabinets, sky survey space telescopes and extravehicular exposure experimental devices in the sealed cabin.
In addition, there are independent load interfaces and large hanging points outside the sealed cabin, and dozens of extravehicular load projects have been planned in the application and development stage.
Zhang Wei said that among the four research fields in the future, space life science and human body research should deeply study the influence and mechanism of various factors of the space environment on the cells, tissues, organs and other levels of living organisms, such as plants, animals, microorganisms, etc. Research on the response mechanism of growth, development, genetics, aging, etc. under space conditions, explore and recognize the laws of growth, development and reproduction of living organisms in space; and use the special environment of space to develop innovative drugs and medical technologies, such as synthetic biological manufacturing, protein-based crystallization space drug development, etc.
The main research of microgravity physics science is to reveal the essential laws of the motion of matter under the cover of gravity, including research in the fields of microgravity fluid physics, combustion science, space material science and microgravity basic physics.
For example, research on hydrodynamics driven by surface tension, laminar and turbulent combustion characteristics under microgravity conditions; the preparation of new materials such as high-entropy alloys, porous ceramics, laser crystals and nanomaterials using microgravity and containerless conditions, Realize 100 pK ultra-low temperature Bose-Einstein condensate (BEC) and carry out basic frontier experiments of ultra-cold atomic physics such as low-temperature quantum phase transition; establish space high-precision time-frequency system, conduct high-precision testing of general relativity, global gravity potential measurement, etc. .
The field of space astronomy and earth science uses astronomical observation facilities such as the Sky Survey Optical Telescope (CSST) and the High Energy Cosmic Radiation Detection Facility (HERD) to carry out dark matter and dark energy, the formation and evolution of cosmic structures, the origin and evolution of galaxies, and the formation and evolution of supermassive black holes. Research on evolution, origin of cosmic rays, and exploration of extrasolar planets; and focus on major issues related to the sustainable development of human society, such as global climate change, carbon peaking and carbon neutrality, and carry out research and verification of new earth observation technologies and systems .
In the field of new space technology and applications, it is necessary to develop space new technology experiments such as space robots and autonomous systems, space intelligent manufacturing and construction, microsatellite formation and applications, earth-moon space optical communication and autonomous navigation technology, core components and components, etc. The ability to explore, develop and utilize space.
