Core Viewpoint - The successful landing of the Shenzhou-20 spacecraft marks a significant advancement in China's space recovery operations, utilizing an unmanned search model for the first time [2][3]. Group 1: Unmanned Search Operations - This mission is the first to employ an unmanned search model for the recovery of the Shenzhou spacecraft, replacing traditional helicopter-based aerial teams with drone and unmanned vehicle teams [2]. - The new search model combines "drone search + unmanned vehicle observation + ground handling," providing valuable experience for future missions [2]. Group 2: Operational Challenges and Preparations - The East Wind landing site, located at the edge of the Badain Jaran Desert, experienced extreme cold, with temperatures dropping to -23.8 degrees Celsius on the morning of January 19 [2]. - To ensure effective operations in the cold environment, multiple training sessions were conducted, including collaborative flight training and cold weather adaptation training [2]. Group 3: Technological Implementation - A comprehensive optical measurement and control network was established in advance to ensure clear imagery of the landing site, allowing for rapid target detection and tracking [2]. - The unmanned vehicles successfully transmitted real-time images of the landing capsule to the command center shortly after the capsule deployed its parachute [3]. Group 4: Historical Context - The East Wind landing site was first utilized in 2016, and it has since been involved in various recovery missions, including the first manned mission recovery in 2021 [3]. - The Shenzhou-20 mission represents the first unmanned spacecraft recovery operation conducted at the East Wind landing site [3].
