Core Viewpoint - The Shenzhou-20 spacecraft successfully completed its return mission, demonstrating the capability for long-duration space missions and effective emergency response measures in China's manned space program [1][3]. Group 1: Mission Success - The Shenzhou-20 spacecraft returned successfully on January 19, 2026, after a total of 270 days in orbit, validating its ability to dock and remain in space for nine months [1]. - The spacecraft was launched on April 24, 2025, and initially delayed its return due to suspected impact from space debris, leading to extended on-orbit experiments [1]. Group 2: Emergency Response - Following the discovery of potential damage to the spacecraft's window, the mission command quickly organized simulations and tests, adjusting the mission plan and activating emergency protocols [1]. - An emergency launch of the Shenzhou-22 spacecraft was conducted on November 25, 2025, marking the first emergency launch in China's manned space history [3]. Group 3: Safety Measures - To mitigate return risks, astronauts from the Shenzhou-21 crew conducted external inspections of the Shenzhou-20's window using high-definition cameras [1]. - A window crack treatment device was developed and installed by astronauts inside the Shenzhou-20 to enhance thermal protection and sealing during re-entry [1].
