Today, the ninth batch of space science experiment samples from the China Space Station was successfully delivered to scientists for follow-up research.The ninth batch of space science experiment samples from the China Space Station returned successfully yesterday with the Shenzhou 21 spacecraft, involving 26 experimental projects, including life experiment samples, material experiment samples, and combustion experiment samples.

The total weight of the experimental samples, including experimental mice, is 46.67 kilograms.

The downstream experimental samples include 9 types of life experimental samples including experimental mice, zebrafish and hornworts, Streptomyces, planarians, brain organoids, macrophages, and hepatocytes.

In addition, there are 32 material samples in three categories, including tungsten-hafnium alloys, soft magnetic materials, hydrated salt phase change and simulated lunar soil, radiation-resistant optical fibers, new thermal control coatings, and space thin film solar cell protection, as well as three types of combustion experimental samples: burners, soot collection plates, and collection covers.

Except for mice, which were initially studied on-site after landing, all other life experiment samples have been transported to Beijing and delivered to relevant scientific research teams.

Scientists will subsequently conduct biological analyzes such as transcriptome sequencing and proteomic testing on the returned life-like cell samples, study the impact of the microgravity environment on the body in multiple dimensions from cells to 3D tissues, and analyze its key biological mechanisms and intervention targets, providing new clues for related disease prevention and intervention.

For material experimental samples, scientists will conduct testing and analysis of tissue morphology, chemical composition, etc., and study the influence of gravity on material growth, component segregation, etc. Relevant research results will promote the future space application of high-performance solar cell protection materials and lunar base construction material preparation processes, and provide theoretical foundation and technical support for satellite communications and space exploration.

For the returned combustion experimental samples, the scientific research team will conduct research on the analysis of the generation characteristics of nanocarbon particles. The research results are expected to provide technical support for the development of new energy systems, space fire protection technology and the preparation of advanced functional nanocarbon materials.
