BEIJING, Nov. 15 (Xinhua) — The final samples from 26 scientific experiments conducted aboard the Chinese space station, weighing about 46.67 kg, were delivered to Earth on Friday, according to the Space Application Engineering and Technology Center of the Chinese Academy of Sciences (CAS).
As part of the ninth transfer of materials from the orbital laboratory, the Shenzhou-21 return capsule delivered to Earth samples obtained during experiments in the fields of space life sciences, materials science, and combustion research.
After landing, the mice participating in the life science experiments were immediately subjected to "field treatment." Researchers will analyze their behavior and key physiological and biochemical parameters to understand the animals' responses to stress and their adaptation mechanisms to spaceflight conditions. The scientists believe these results will provide crucial insights into how the space environment affects living organisms.
Other biological samples, including zebrafish, hornwort, streptomycetes, planarians, and brain organoids, as well as individual samples for materials science and combustion experiments, were delivered to the aforementioned center in Beijing at 12:40 AM on Saturday. After an initial condition check, these samples were handed over to research teams for further study. The remaining samples will be delivered to Beijing aboard the Shenzhou-21 return capsule.
The scientists will then conduct transcriptome sequencing of the extracted cell samples to investigate the changes induced by microgravity, identify key biological mechanisms, and identify potential intervention targets. This work is expected to contribute to the development of new strategies for the prevention and treatment of related diseases.
According to the center, the researchers will study the microstructure, chemical composition, and elemental distribution of returned material samples, such as tungsten-hafnium alloys, soft magnetic materials, and relaxed ferroelectric single crystals.
These analyses will help determine how gravity affects material growth, compositional separation, solidification defects, and overall performance, as well as the performance of materials in space environments.
The results are expected to advance a range of applications, including protective materials for high-efficiency solar cells, high-gain, radiation-hardened optical fibers, and innovative materials processing technologies for lunar infrastructure. These developments will provide important theoretical and technical support for satellite communications and space exploration.
After returning samples from the combustion experiments, including burners, soot collection plates, and lids, scientists will analyze the resulting flame-induced semiconductor nanomaterials, soot samples, and nanocarbon particle formation characteristics, the center said.
The results of this work may contribute to advances in the fields of extraterrestrial flame synthesis of nanomaterials, new energy systems, fire safety in space, and the production of functional nanocarbon. -0-
