Dongfeng Landing Site Completes Final Full-System Integrated Drill, Ready to Welcome Shenzhou-21 Crew Home
Xinhua News Agency, Jiuquan, May 27 (Li Guoli, Zhang Yan) — The Shenzhou-21 crew will return to Earth in the coming days aboard the Shenzhou-22 crewed spacecraft. On the evening of the 27th, the Dongfeng Landing Site completed its second full-system integrated drill, comprehensively testing capabilities in search-and-rescue recovery mission organization and command, coordination, and emergency support.
This was the final full-system integrated drill at the Dongfeng Landing Site before the Shenzhou-21 crew's return. Prior to this, the Dongfeng Landing Site had already organized and completed search-and-rescue team communications coordination and air-ground coordinated search-and-rescue training, among other exercises.
"In response to the possibility that the return capsule may land on special terrain such as saline-alkali land, desert, or bodies of water, we also conducted intensive training, with the aim of improving personnel's emergency rapid-response capabilities," said Li Binbing of the Jiuquan Satellite Launch Center.
It is reported that the Shenzhou-22 crewed spacecraft is expected to land during the dusk period, with search-and-rescue and handling operations spanning a day-night transition and the transfer-out phase occurring at night. The landing site will continue to employ the mature UAV illumination deployment plan used in previous nighttime search-and-rescue operations, ensuring sufficient overall lighting brightness across the landing site, clear visibility, and the ability to support continuous day-and-night operations.
"To improve the mobility efficiency and safety of ground teams, we have newly built an asphalt road totaling more than 50 kilometers in the western zone of the landing site, which will significantly shorten the time for ground teams to conduct search-and-rescue and handling operations," said Mao Yongjun of the Jiuquan Satellite Launch Center at a mission briefing.
Currently, the three astronauts have been in orbit for nearly seven months, which places higher demands on egress transfer, medical monitoring, and medical support (医监医保). To this end, medical monitoring and support personnel from the Jiuquan Satellite Launch Center strictly adhered to protocols and performed precise operations during the drill; a dedicated accessible lift platform for astronauts was also specially installed in the landing zone.
"This lift platform was specially designed for astronauts returning from the weightless environment of space to Earth's gravitational environment, and can prevent astronauts from experiencing orthostatic hypotension and other accidental injuries," a staff member at the drill site explained.
It is understood that the communications equipment newly tested for use in this mission features high bandwidth and low latency, with significant improvements in call quality and communications stability. "The network configuration method is more flexible — wherever the search-and-rescue teams go, network coverage extends there simultaneously," said Long Kunming of the Jiuquan Satellite Launch Center.
At present, all search-and-rescue forces at the Dongfeng Landing Site are ready, equipment is in good condition, meteorological conditions are favorable, and the conditions for executing the return mission are in place.
