Shijian 19

China's first reusable returnable satellite, designed for repeated orbital deployments with a capsule rated for up to 15 reuse cycles. The primary experiments focused on space breeding: the capsule carried approximately 1,800 plant material samples and more than 1,000 species of microorganisms, with researchers seeking radiation-induced variations that could improve agricultural traits. International payload users from Thailand and Pakistan participated alongside domestic organizations.

The capsule returned to Earth on 11 October 2024, landing at the Dongfeng Landing Site in Inner Mongolia.
