China launched an uncrewed Shenzhou-22 on Nov. 25 to replace a capsule at the Tiangong space station after debris likely caused a crack in Shenzhou-20’s window. The emergency launch and fast docking restored the station’s backup return vehicle and validated China’s “one-for-one, rolling backup” approach. Shenzhou-20 will remain docked for further tests and possible repair, and officials say another emergency rocket will be readied if needed.
