On May 1st, it was announced that at 17:46 on April 30th, the return capsule of the Shenzhou-17 manned spacecraft successfully landed at the Dongfeng landing site.
On-site medical personnel confirmed that astronauts Tang Hongbo, Tang Shengjie, and Jiang Xinlin are in good health. The Shenzhou-17 manned space mission has achieved complete success, with the sixth batch of Chinese space station scientific experiment samples smoothly returning with the Shenzhou-17 spacecraft.
According to CCTV News, the scientific experiment samples returned this time involve 23 scientific experiment projects, including human osteoblasts, bone marrow mesenchymal stem cells, protein crystals, organic molecules of life, seeds, and 32 other life experiment samples, as well as 18 material samples such as containerless materials, high-temperature materials, and materials exposed to outer space, with a total weight of approximately 31.5 kilograms.
Early this morning, life science experiment samples were transported in advance to the China Academy of Space Technology Space Application Engineering and Technology Center in Beijing. As the overall unit of the manned space engineering space application system, the China Academy of Space Technology Space Application Center inspected and confirmed the basic status of the returned life experiment samples and delivered them to scientists on-site.
Subsequently, scientists will conduct biological analyses such as transcriptome sequencing and proteomics testing on the returned life cell samples, studying the biological mechanisms of cells under microgravity conditions to provide new clues for disease prevention and intervention.
Crystal diffraction analysis will be performed on life protein samples to obtain more precise three-dimensional structural information of proteins, studying target proteins to provide technical support for drug development and vaccine research.
Material science experiment samples will be transported to Beijing with the return capsule of the Shenzhou-17 spacecraft. Scientists will conduct tests and analyses on the morphology, chemical composition, and distribution differences of ground and space samples, studying the impact of gravity on material growth, component segregation, and solidification defects to support the preparation of important new materials. Breakthroughs are also expected in research areas such as lunar soil reinforcement materials and in-situ resource utilization of lunar soil.
