Core Viewpoint - The return of the Shenzhou-19 manned spacecraft has been delayed due to adverse weather conditions, specifically strong winds and sandstorms, which do not meet the strict meteorological requirements for a safe landing [1][2]. Group 1: Mission Status - The East Wind landing site is currently in good condition, with all systems and personnel prepared for the recovery mission, despite the weather-related delay [1]. - The decision to postpone the return was made to ensure the safety and health of the astronauts, as well as the success of the mission [1]. Group 2: Weather Impact - Strong winds can significantly affect the spacecraft's attitude control and landing accuracy, potentially leading to issues such as dragging or rolling after touchdown [1]. - Adverse weather also impacts the normal operations of the search and rescue teams, including limitations on helicopter takeoff and ground team movements [1]. Group 3: Preparedness and Historical Context - The East Wind landing site has previously conducted multiple coordinated drills for recovery operations, ensuring readiness for any landing location [2]. - The East Wind landing site has been operational since 2016 for manned spaceflight recovery tasks, successfully completing various missions, including the Shenzhou-12 spacecraft in 2021 [2].

Core Viewpoint - The successful launch of the Shenzhou-20 manned spacecraft marks a significant milestone in China's manned space program, entering the application and development phase of the space station [4]. Group 1 - The Shenzhou-20 spacecraft was launched on April 24, 2025, and successfully separated from the Long March 2F rocket approximately 10 minutes after liftoff [1]. - The crew of Shenzhou-20 will conduct various experiments in fields such as space life and human research, microgravity physics, and new space technologies during their time on the space station [3]. - This mission is the fifth manned flight in the application and development phase of China's manned space program and the 35th launch since the project's inception [4]. Group 2 - The space station assembly is in a good working condition and is ready for the docking with the Shenzhou-20 spacecraft [5]. - A total of 26 astronauts and 41 missions have been completed in space by China to date [4].
