Space Seeds and More: China's First Reusable Satellite Mission

China's first reusable satellite, Shijian-19, came back to Earth after a two-week trip in space. It launched on September 27 from the Jiuquan Satellite Launch Center and landed on October 11 in the Gobi Desert. The China National Space Administration (CNSA) held a ceremony on October 24 to reveal the satellite's contents. The mission carried a variety of payloads, such as seeds, microorganisms, and electronic components. These items were sent to space to see how cosmic rays might change them. Cosmic rays, which are usually blocked by Earth's atmosphere, can cause mutations in seeds. These changes could lead to better crops that are more resistant to pests or drought.China has been sending seeds to space for a while now. Liu Luxiang, an expert from the Chinese Academy of Agricultural Sciences, explained that the goal is to create new seed resources. These new seeds can be mixed with existing varieties to improve crop quality. The Shijian-19 mission also involved international partners from Thailand and Pakistan. The satellite carried around 1, 800 plant materials and over 1, 000 microorganism species. This mission aims to advance space science, support genetic innovation, and promote international cooperation.
