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]

中新社北京4月30日电 题："龙马乘组"天外归来 神舟飞船首次降落东风着陆场东区 中新社记者 马帅莎 4月30日，神舟十九号乘组结束为期183天的"太空出差"，从400公里天外平安归来。 该乘组由指令长蔡旭哲和两名"90后"航天员宋令东、王浩泽组成，被称为"龙马乘组"。东风着陆场是他 们返回地球的"第一站"。受着陆场大风天气影响，原计划4月29日实施的返回任务被推迟一天。 东风着陆场位于中国西北戈壁深处，植被少，沙石多，春季大风天气频发。经测定，原定返回时段返回 区实况风速和能见度存在超条件风险。酒泉卫星发射中心张芳指出，气象条件对航天员安全返回至关重 要，大风和扬沙会对飞船返回控制精准度产生较大影响。 中国载人航天工程始终把确保航天员安全摆在首要位置。面对新情况新考验，工程迅速制定应对举措， 调整神舟十九号飞船返回窗口、区域，争取用最安全的方案尽早迎接航天员回家。 30日4时，神舟十九号载人飞船撤离空间站组合体，3名航天员踏上回家之旅。此时，东风着陆场气象条 件满足任务要求，参试相关系统也做好了各项准备迎接航天员回家。 据中国航天科技集团五院载人飞船回收试验队总体负责人介绍，神舟十九号载人飞船仍延续神舟十三 ...
