Experimental samples such as nematodes, regenerated rice, and alloy materials were successfully returned from the Chinese space station and delivered to the experimental scientist space
On the morning of June 4, 2023, the fourth batch of space science experimental samples from the Chinese space station returned to the ground with the return capsule of the Shenzhou-15 spacecraft, and the space application system led by the Chinese Academy of Sciences was delivered at the Dongfeng landing site.
At about 14:00 on the 4th, some experimental samples were transported to the Space Application Engineering and Technology Center of the Chinese Academy of Sciences in Beijing. The overall space application system and relevant experimental personnel checked and confirmed the basic status of returned experimental samples, and handed over to relevant experimental scientists for follow-up research.
The space application system, accompanied by the return module of the Shenzhou-15 spacecraft, carried out a total of 15 scientific project experimental samples, including life experiment samples such as cells, nematodes, Arabidopsis, and regenerated rice, as well as various alloy materials, new infrared detector materials, amorphous thin film materials, and other material experimental samples. The total weight of the downward experimental sample is over 20 kilograms.

Subsequent scientists will conduct molecular biology, cell biology, in orbit growth, development, and metabolism analysis on returned life samples. Through comparative analysis with the ground, the laws and molecular mechanisms of the effects of space microgravity and radiation on experimental samples will be analyzed, providing a theoretical basis for the further creation of crops adapted to the space environment and the development and utilization of space microgravity, radiation, and other resources. The material experimental samples will be tested and analyzed in the laboratory to reveal the laws of material physical properties and chemical changes that are difficult to obtain in the ground gravity environment, obtain key conditions for high-performance preparation technology, and guide the preparation of new ground materials.
