Gamingdeputy reported on April 24 that the Shenzhou 18 manned spacecraft officially announced that it would be launched at 20:59 on April 25. The astronaut crew consisted ofYe Guangfu, Li Cong, Li Guangsu It consists of 3 astronauts and stays on the space station for about 6 months.
According to an official statement from the China Manned Space Engineering Office, after the space station mission enters normal duty, the Shenzhou 18 astronaut crew will manage and care for the space station and application loads as planned, and conduct space station maintenance and status inspections during their stay. Ensure the safe, reliable and efficient operation of the space station.

According to reports, the crew will use the in-cabin scientific experiment cabinet and extravehicular loads to conduct research in the fields of basic microgravity physics, space material science, space life science, aerospace medicine, and aerospace technology.Conducted more than 90 trials (experiments).
For example, this time Shenzhou 18 will launch experimental devices and related samples, and will implement the country's first on-orbit aquatic ecological research project.Using zebrafish and hornwort as research objects, we will establish a stably operating space self-circulating aquatic ecosystem in orbit, achieving my country's breakthrough in cultivating vertebrates in space.. The world's first on-orbit study of the function of plant shoot tip stem cells will also be carried out to reveal the adaptive mechanism of plant evolution to gravity and provide theoretical support for the subsequent directional design of space crops adapted to the space environment.
Gamingdeputy Note: Zebrafish is a tropical freshwater fish.It is an important vertebrate model organism in the field of scientific research., especially in the study of the regenerative ability of organisms. Zebrafish are easy to breed, have a short reproductive cycle, large egg production, in vitro fertilization and in vitro development of embryos, and the fertilized eggs are almost transparent. This feature makes zebrafish greatly convenient for scientific researchers, making it suitable for scientific research, and has become a life science A new favorite for research.
While the crew is in orbit, they will also carry out 6 cargo airlock cabin evacuation missions and 2-3 extravehicular activities. Based on the space debris protection measures currently in place at the space station, the Shenzhou 18th astronaut crew will Through extravehicular activities, debris protection and reinforcement devices are installed on extravehicular pipelines, cables and key equipment, and extravehicular inspections are carried out as appropriate to further ensure the safety of the space station.

Zhong Hongen, deputy chief designer of China Manned Space Engineering Space Application System, also pointed out,In the future, our country also plans to conduct experiments on mice on the space station.including experiments on the growth of mice in space, and experiments on mice being fertilized on the ground and then bred in space, hoping to study the possibility of human reproduction in space through these experiments.
In addition, the Shenzhou 17 crew plans to return to the Dongfeng Landing Site on the 30th of this month. The approximately 6-month space mission has carried out a total of 84 on-orbit space application experiments and generated more than 60 types of more than 200 samples of various types. , involving many fields such as space life science and biotechnology, aerospace medicine, space materials science, etc.It will return to the ground as planned with the return capsule of the Shenzhou 17 spacecraft.. Subsequently, these samples will be analyzed and studied in depth by scientists, and it is expected to achieve a number of important scientific application results in the preparation of high-performance multi-component alloys and functional crystal materials, and the differentiation of bone stem cells to inhibit bone loss.
In the early stage, the solar wing cables of the space station's Tianhe core module were hit by space debris, resulting in a partial loss of power supply capacity. Through two extravehicular activities by the crew of Shenzhou 17,Completed my country's first extravehicular maintenance mission, eliminating the impact of the impact on the sun wing of the core modulegiving full play to the role of humans in space, showing that spacecrafts with people taking care of them can better deal with unexpected problems in orbit.
