面临全新的巨大考验 我国载人登月要过几道关？

Core Viewpoint - China is progressing towards its goal of manned lunar landing by 2030, with significant advancements in spacecraft and technology [11][29]. Group 1: Manned Lunar Mission Progress - The "Dream Boat" manned spacecraft successfully completed a zero-height escape flight test, enhancing safety for future missions [11][20]. - The "Moon Catcher" lunar lander has successfully undergone comprehensive verification tests for landing and takeoff [11][22]. - The training of the fourth batch of reserve astronauts has commenced, with 10 selected candidates, including 8 pilots and 2 payload specialists from Hong Kong and Macau [11][20]. Group 2: Technical Challenges and Solutions - The mission involves launching two rockets to send the lunar lander and manned spacecraft to a translunar trajectory, followed by docking in lunar orbit [14][21]. - The new "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 existing rockets [16][19]. - The "Dream Boat" spacecraft is designed to support both lunar landing and near-Earth space station missions, featuring enhanced safety and life support systems [20][27]. Group 3: Lunar Landing and Return - The lunar lander will serve as the operational center for astronauts on the moon, supporting their activities and scientific research [22][24]. - The return journey involves a complex "space skipping" maneuver to ensure safe re-entry into Earth's atmosphere, which requires precise navigation and thermal protection [26][28]. - The lunar mission aims to enhance understanding of the moon and lay the groundwork for future lunar research facilities and continuous exploration [28][29].
