A full-system fire drill to prepare for the return of the Shenzhou-21 crew was successfully completed at the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on Wednesday. ⁣ ⁣ The drill tested the organization, coordination, and emergency response capabilities of all units involved in the retrieval of the return capsule.⁣ ⁣ The Shenzhou-21 astronauts, Zhang Lu, Wu Fei and Zhang Hongzhang, will return to Earth aboard the Shenzhou-22 manned spacecraft, which is scheduled to land around dusk. Having spent seven months in orbit, the crew is set to break the record for the longest stay in space by Chinese astronauts.⁣ ⁣ #Shenzou21 #Dongfeng #Space
