China's first reusable and returnable test satellite has successfully returned to earth, bringing back seeds which were treated in orbit. The breakthrough is set to provide an innovative way to tackle global food security issues from outer space. CGTN's Wan Hongjia explains. 

The China National Space Agency handed over payloads from the Shijian-19 satellite on Thursday, marking a significant milestone for China's first reusable and returnable test satellite.

Launched on September 27th, the Shijian-19 spent two weeks in orbit, achieving remarkable breakthroughs in reusability and a damage-free recovery. 

WAN HONGJIA Beijing "The Shijian-19 satellite carries a payload of 20 categories, including staple and economic crops, microbial breeding experiments, and space technology tests. The platform is also open to international partners like Pakistan and Thailand."

TATPONG TULYANAND Lecturer, Mahidol University "This is the first time that Thailand has bioscience research in space. Chinese space agency is actually the only player that has returnable and reusable satellite. So we can send the seeds to germinate in space, and then return on earth. Then we can have the plant material for future analysis."

Back on earth, the Chinese Academy of Agricultural Sciences is exploring how cosmic radiation can enhance genetic traits.

LIU LUXIANG Chief Scientist, China's Space Breeding Program "For example, Thai rice is renowned for its exceptional fragrance. By sending seeds to space, we can unlock new genetic resources. This can ensure the preservation of the seeds' superior qualities while also boosting its resilience and yield."

The Shijian-19 satellite effectively used its advanced returnable platform and was able to shorten breeding periods while also increasing its payload capacity. It completed nearly a thousand space breeding experiments, seeking cosmic solutions for global food security issues and sustainable agriculture.
