任务详情
Ninth crewed flight to the Chinese space station. Due to damage sustained by the spacecraft's descent module porthole window by orbital debris collision found in early November 2025, the spacecraft was deemed unsuitable for crew return. Shenzhou 22 was launched without crew as replacement, and Shenzhou 20 will return to Earth without crew after EVA inspection by the onboard crew.
