Zheng Huiqiong, a researcher at the Center for Excellence in Molecular Plant Sciences under the Chinese Academy of Sciences (CAS), processes Arabidopsis samples from China's Tiangong space station at a biology lab of the Technology and Engineering Center for Space Utilization under the CAS in Beijing, capital of China, Dec. 5, 2022. Chinese scientists have completed the life-cycle growth experiments of rice and Arabidopsis in the Chinese space station and successfully obtained their seeds, said the CAS on Monday. With the safe landing of the Shenzhou-14 spaceship's return capsule at the Dongfeng landing site Sunday night, the seeds of rice and Arabidopsis, which have undergone a 120-day life cycle, were delivered to China's manned space program's space application system along with other samples.
