CTOnews.com, December 1, according to official information from the Chinese Academy of Sciences, the space application system led by the Chinese Academy of Sciences has carried out two scientific experiments, "Space radiation Metering and Biological damage Assessment Technology" and "Molecular Network Research on Plant Cell structure and function regulated by Space microgravity Environment". Samples and experimental units.

▲ Tu Yuan: China manned Space Engineering Office officially, the long March II F Yao 15 carrier rocket carrying the Shenzhou 15 manned spacecraft was ignited and launched from the Jiuquan Satellite launch Center 23:08 on November 29. Subsequently, the Shenzhou 15 manned spacecraft successfully separated from the rocket and entered the scheduled orbit. The astronauts were in good condition and the launch was a complete success.

The research team of the Chinese Academy of Sciences said that with the vigorous development of space activities, the study of the response, survival, change and adaptation of organisms, including human beings under special space conditions such as weightlessness and cosmic radiation, has become an important topic in space life science research.

Among them, the experiment of "space radiation metrology and biological damage assessment technology" will be carried out in the small general culture experiment module of the life and ecology experiment cabinet of the experimental module. Through the fluid control of microfluidic chip, the single nematode is cultured, optically monitored and analyzed to realize the on-orbit detection of radiation damage markers, and to establish a method of space radiation metrology and biological damage assessment. Provide important support for space radiation damage assessment and medical diagnosis and protection. Through the systematic biological analysis of returned nematode samples, the molecular mechanism of radiation damage and repair of nematodes caused by space radiation was revealed, and the synergistic mechanism of biological effects of space radiation and microgravity was studied.

The experiment of "Molecular Network Research on the Regulation of Plant Cell structure and function by Space microgravity Environment" will be carried out in the general biological culture experiment module of the life ecology experiment cabinet of the space microgravity environment. Through the study of the molecular network of plant cell structure and function regulated by space microgravity environment, the signal transduction mechanism and regulation network of plant perception microgravity environment are revealed. To study the mechanism of hormone transport system involved in plant response to microgravity, the mechanism of microgravity-induced transcription factors regulating plant cell wall formation, and to clarify the mechanism of plant adaptation to space microgravity environment.

CTOnews.com learned that the Chinese Academy of Sciences said that with the continuous uplink of experimental devices and samples, multidisciplinary, serialized and long-term space science experiments will be carried out, while maintaining and upgrading the scientific payloads of the space station, so as to maintain the advanced nature of the scientific experiment facilities of the space station.
