The reporter learned from the National Space Administration that at 10:39 am on October 11th, China successfully recovered its first reusable return type technology experimental satellite, the Shijian 19 satellite, from the Dongfeng landing site. The recovered payloads, including plant and microbial breeding payloads, autonomous controllable and new technology verification payloads, space science experiment payloads, social welfare and cultural creativity payloads, have all been successfully recovered. The Practice-19 satellite is an important new technology experimental satellite during China's 14th Five Year Plan period. It was launched from the Jiuquan Satellite Launch Center on September 27th and has broken through key technologies such as reusability, non-destructive recovery, and high micro gravity support through flight tests. It has verified the technical indicators of the new generation high-performance reusable return space test platform and achieved various expected test results. The Practice-19 satellite has the characteristics of high microgravity level, good timeliness, and strong downward capability. It is an efficient high microgravity horizontal space experimental platform that can support research in microgravity science, space life science, and other fields. This flight mission carried out space breeding, new technology verification, and space science experiments, focusing on promoting the development and application of new space technologies. At the same time, it carried multiple international cooperation payloads, becoming a good platform for promoting international cooperation in space exploration and utilization, which is of great significance.
