Since the launch of Shenzhou-21, China's Tiangong Space Station has entered an unprecedented phase of dual-crew operations, with the Shenzhou-20 astronauts remaining in orbit longer than initially planned following a suspected space debris impact on their return spacecraft. This situation has prompted China's space authorities to activate comprehensive risk assessments and emergency procedures, ensuring crew safety remains paramount.
On November 5, the China Manned Space Agency (CMSA) postponed the scheduled return of Shenzhou-20, citing concerns over possible damage caused by a debris event. Crew commander Chen Dong, operator Chen Zhongrui, and science operator Wang Jie continue to live and work aboard the station, joined by the three-member Shenzhou-21 crew.
CMSA officials reaffirmed: "Following the postponement of the Shenzhou-20 manned spacecraft return mission, the project team, adhering to the principles of 'life first, safety first,' immediately activated emergency plans and measures... All tasks are progressing steadily and orderly according to schedule".
Both Shenzhou-20 and Shenzhou-21 astronauts are conducting joint scientific experiments, made possible by robust station systems and supplies delivered by Tianzhou cargo ships.
Engineers and risk teams have performed simulation analysis and system testing on the Shenzhou-20 capsule, while ground teams continue return drills at the landing site.
The spacecraft remains docked to Tiangong, with ongoing technical assessments. No official decision on a revised return date has been published, but agency statements and recent reporting suggest preparations continue toward a near-future crew return, using Shenzhou-20 for reentry.
CMSA reports indicate the capsule's "critical product status evaluations and quality confirmations" are underway. All procedures are "strictly followed," including joint debugging and simulation exercises.
International and Chinese government media have mirrored this official stance, emphasizing crew safety and orbital readiness.
At this time, there is no confirmed emergency launch or alternate rescue planned. However, the next crewed flight-Shenzhou-22-remains in routine preparation for a scheduled 2026 launch, with hardware on standby at Jiuquan Satellite Launch Center.
Should contingency plans be required, Shenzhou-22 and its Long March launch vehicle can be made ready for orbital rendezvous in as little as 8.5 days, according to official sources, although this outcome is considered unlikely.
CMSA stated: "The Shenzhou-20 crew is working and living normally, conducting in-orbit scientific experiments together with the Shenzhou-21 crew", ... with "All tasks are progressing steadily and orderly according to schedule."
