“飞天战衣”光荣退役 将助力中国登月服研制

Core Viewpoint - The successful return of the Shenzhou-20 spacecraft marks a significant achievement in China's space program, particularly in the development and evaluation of extravehicular spacesuits, which have demonstrated extended service life and enhanced performance in space missions [1][3]. Group 1: Spacesuit Performance and Evaluation - The extravehicular spacesuit (B) has been used in 8 manned missions by 11 astronauts, achieving a record of "4 years and 20 uses," which is a significant extension of its intended lifespan [12]. - The spacesuit is designed for a storage period of 3 years in orbit, with a minimum of 15 extravehicular activities, but has been successfully evaluated and extended to support 20 activities over 4 years [3][12]. - The data collected from the spacesuit's performance in space will contribute to future research and development, particularly in improving the durability and efficiency of upcoming spacesuit models [5][8]. Group 2: Technological Advancements and Future Applications - China's spacesuit technology has progressed from a following position to a competitive one internationally, with the first batch of spacesuits effectively supporting 46 extravehicular activities [3]. - The experience gained from the current spacesuit will inform the design and production of future models, including those intended for lunar missions, providing a solid foundation for advancements in space exploration technology [10][14]. - The ongoing analysis of the returned spacesuit will focus on identifying weaknesses and enhancing the reliability and safety of future designs [7][8].
