载人登月，要过几道关（科技视点）

Core Viewpoint - China aims to achieve its first manned moon landing by 2030, with significant progress in the development of the "Dream Boat" manned spacecraft and the "Moon Catcher" lunar lander, indicating a strong commitment to advancing its space exploration capabilities [10][24]. Group 1: Manned Moon Landing Plans - The primary flight process for the manned moon landing involves launching two rockets to send the lunar lander and manned spacecraft to a trans-lunar trajectory, docking in lunar orbit, landing on the moon, and returning to Earth with samples [5][13]. - The "Dream Boat" spacecraft is designed to carry up to seven astronauts and features advanced safety systems, including an autonomous escape capability in emergencies [19][24]. - The "Moon Catcher" lunar lander will serve as the operational center for astronauts on the moon, supporting their activities and scientific research [21][23]. Group 2: Technological Developments - The Long March 10 rocket is being developed to meet the required payload capacity of at least 27 tons for lunar missions, addressing the limitations of current rockets [15][17]. - The "Dream Boat" spacecraft has undergone successful zero-height escape flight tests, enhancing safety for future lunar missions [19][24]. - The lunar lander has completed critical landing and ascent verification tests, ensuring its capability to safely land and take off from the moon [21][24]. Group 3: Challenges and Innovations - The mission will face challenges such as extreme temperatures, vacuum conditions, and complex terrain on the moon, necessitating thorough preparation and technology validation [22][24]. - The return journey to Earth involves a "space skipping" technique to manage high-speed re-entry, ensuring the safety of astronauts and the integrity of lunar samples [26][27]. - Continuous advancements in navigation and control systems are being pursued to ensure a smooth and safe return from the moon [27][28].
