中国人民解放军航天员大队航天员、神舟十五号飞行乘组指令长费俊龙是中国首批航天员。2005年10 月，他担任指令长，和聂海胜一起执行神舟六号载人飞行任务。2022年11月，费俊龙再次担任指令长， 和队友邓清明、张陆一起执行神舟十五号载人航天飞行。费俊龙说，非常自豪也很荣幸能够见证中国航 天史上首次"太空会师"，也亲自经历并见证了中国空间站的建成。 中国载人航天工程着陆场系统副总设计师、测控系统专家孙威工作28年来，亲历并见证了中国载人航天 工程测控通信系统和着陆场系统的发展与建设。他说，2003年，中国首次载人飞行时，测控通信系统的 覆盖率只有15%左右，飞船绕地球飞行一圈的90分钟里只有约13分钟能够与地面通信。今天测控通信信 号几乎覆盖全程，通过空间站内设计安装的无线通信设备，可以保证航天员与地面进行顺畅的音频、视 频通信。 中国载人航天工程空间应用系统总指挥助理、中国科学院空间应用工程与技术中心研究员张璐是一 名"85后"航天人，十余年来，他一直从事空间站应用系统的总体设计和科学载荷研制工作。"我们的目 标就是将地面上各类学科的综合性实验室搬到太空去，放进一个不到2立方米的实验柜内，支持科学家 开展相关的 ...

Group 1 - The core message emphasizes the confidence in China's space technology and the rigorous training of astronauts, highlighted by the phrase "I feel good" upon exiting the spacecraft [1] - The communication coverage during manned space missions has significantly improved from 15% in 2003 to nearly full coverage today, ensuring smooth audio and video communication between astronauts and ground personnel [2] - The management of China's manned space program involves a dual-line system of administrative command and designer systems, ensuring comprehensive oversight from top-level planning to individual components [2][3] Group 2 - Unified management of overall technology, research quality, and infrastructure is crucial to avoid disconnection in traditional models, allowing for rapid problem-solving across all levels of the project [3] - The design management philosophy focuses on "overall priority, participation from all parties, and global optimization," integrating over 14 major systems and numerous research units into a cohesive operation [3] - The Chinese space station is currently operating safely in orbit, hosting nine mission crews and conducting various space application experiments, with plans to enhance its capabilities further [3] Group 3 - The team is actively working towards the goal of operating, applying, and developing the space station effectively, with a target of landing Chinese astronauts on the moon by 2030 [4] - A recent successful escape flight test of the new generation of crewed spacecraft marks a significant breakthrough in the lunar exploration program [4]
