神舟二十二号飞船首次实现“无人上行物资+载人下行”模式

Core Viewpoint - The Shenzhou-22 spacecraft is executing an "emergency launch" mission, marking the first implementation of a flexible mode for "unmanned upward cargo + manned downward return" [1] Group 1: Mission Details - The Shenzhou-22 mission was initiated due to the Shenzhou-20 spacecraft sustaining minor damage from space debris, resulting in fine cracks on its window [1][3] - The launch preparation process was significantly expedited, reduced from several days to just 16 days, presenting extreme challenges for assembly, testing, fueling, and system integration [1] Group 2: Technological Improvements - The Shenzhou-22 spacecraft is the first of a new batch and features two major upgrades: a significant enhancement of the instrument system for a more user-friendly interface and a miniaturization of the instrument panel to create more space in the return capsule [5][7] - The improvements in the instrument system not only enhance aesthetics but also provide greater installation space for downward payloads in the return capsule [7]
