Chinese Astronauts Return Safely After Space Debris Delays
The Shenzhou-20 crew returned to Earth aboard Shenzhou-21 after their original spacecraft was damaged by suspected space debris.
Three Chinese astronauts have returned safely to Earth after a nine-day delay caused by damage to their original return spacecraft, Shenzhou-20. The crew—Commander Chen Dong, Chen Zhongrui, and Wang Jie—had been scheduled to return on November 5, 2025, following a six-month mission aboard the Tiangong space station. However, tiny cracks, likely caused by space debris, were discovered in a window of the Shenzhou-20 capsule, rendering it unsafe for reentry.
To ensure the astronauts' safety, the China Manned Space Agency (CMSA) postponed their return and arranged for them to travel back aboard the recently arrived Shenzhou-21 spacecraft. The Shenzhou-21 crew, who had arrived at Tiangong on November 1, temporarily remained without a return vehicle. CMSA announced plans to launch the Shenzhou-22 mission ahead of schedule to provide a replacement return craft for the current station crew.
The incident underscores the growing concern over space debris and its potential impact on space missions. Experts emphasize the need for international cooperation to develop space rescue capabilities and establish compatible docking and communication systems to ensure astronaut safety in such scenarios.
