China delays Shenzhou-20 crew’s return after suspected debris strike 

China has delayed the return of its three-person Shenzhou-20 crew after the country’s human-spaceflight agency reported that the spacecraft’s return capsule may have been struck by a small piece of orbital debris. 

The China Manned Space Agency (CMSA) said in a brief statement that engineers were conducting “impact analysis and risk assessment” after the capsule was “suspected of being hit by a small piece of space debris.” The agency did not specify when the suspected strike occurred or describe the extent of any damage. 

The return of Shenzhou-20 had been scheduled for November 5, 2025, following nearly six months aboard China’s Tiangong space station. The spacecraft remains docked as engineers assess whether it is safe to use for re-entry. CMSA has not released a revised return date. 

Crew safe aboard Tiangong 

The three astronauts — Chen Dong (commander), Chen Zhongrui, and Wang Jie — are reported to be in good health and continuing daily operations aboard Tiangong. Their replacements, the Shenzhou-21 crew, arrived late last week, completing a handover ceremony before the delay was announced. 

If the return module is deemed unsafe, CMSA could opt to have the Shenzhou-20 crew return aboard Shenzhou-21’s spacecraft or dispatch a standby vehicle from Earth. Chinese state media have not indicated that an emergency launch is being prepared. 

CMSA said that all life-support systems aboard Tiangong are functioning normally and that both crews are carrying out joint experiments while engineers evaluate the return capsule’s condition. 

No timeline for re-entry 

International outlets including Reuters, The Guardian and UPI cited CMSA’s statement confirming the delay but noted that details remain scarce. The agency said it would announce an updated landing plan “after completing risk verification.” 

Shenzhou-20 was launched on April 24, 2025, from the Jiuquan Satellite Launch Center in China’s Gobi Desert. The six-month mission is part of a continuous human-spaceflight program that keeps Tiangong permanently occupied. 

The delay marks the first time China has publicly acknowledged a potential debris strike affecting a crewed vehicle. While no injuries have occurred, the incident underscores the persistent danger posed by space debris in low Earth orbit. Even millimeter-sized fragments can cause serious damage at orbital velocities exceeding 25,000 kilometers per hour. 

Tiangong, meaning “Heavenly Palace,” has been operational since 2021 and serves as the centerpiece of China’s long-term crewed-space program. Each Shenzhou mission brings a new crew for scientific research and maintenance tasks. 

The country plans to expand Tiangong with additional laboratory modules and potentially open it to foreign astronauts in the coming years.
