Group 1 - The core viewpoint of the news is that the Zhuque-3 rocket has successfully completed key preparatory tests, including fueling and static ignition, and is now ready for its maiden flight, which is crucial for large satellite constellation networking [1][2] - The Zhuque-3 rocket has undergone a comprehensive series of tests that simulate the entire launch process, ensuring compatibility between the rocket systems and the launch site systems, akin to a "rehearsal" before the actual flight [1] - The next phase of the Zhuque-3 project will focus on orbital launch and recovery tests, with the aim of validating technical capabilities while ensuring quality and safety [1] Group 2 - Zhuque-3 is a domestically developed large-capacity, low-cost, reusable liquid launch vehicle designed for large satellite constellation tasks, featuring a stainless steel main structure [2] - The rocket has a diameter of 4.5 meters for both stages, a fairing diameter of 5.2 meters, a total length of 66.1 meters, a launch mass of approximately 570 tons, and a thrust exceeding 750 tons, allowing for high-precision return and soft landing for reuse [2]

Core Viewpoint - The successful static fire test of the Long March 10 rocket marks a significant step in China's manned lunar program, validating the rocket's engine start and shutdown processes, and supporting future flight tests and missions [1][20]. Group 1: Technical Specifications - The Long March 10 rocket features a parallel configuration of three 5-meter diameter rocket bodies and utilizes seven YF-100K series liquid oxygen/kerosene engines, providing a total thrust of 892.2 tons at sea level [3][10]. - The rocket's design includes both reusable and non-reusable engines, with the reusable variant employing three YF-100N engines capable of dual-axis gimbal [3][11]. - The static fire test was conducted to assess the compatibility of various subsystems and the overall performance of the rocket under ground test conditions [4][7]. Group 2: Ground Testing Importance - Ground tests allow for extensive data collection through numerous sensors, providing a comprehensive analysis of the rocket's status post-test, which is not possible during actual flight tests [4][5]. - Although ground tests cannot fully replicate flight conditions, they can simulate certain parameters to ensure the rocket's systems are functioning correctly [5][6]. Group 3: Launch Infrastructure - The Wenchang Space Launch Site has been expanded to accommodate the Long March 10 rocket, featuring a new launch platform designed for both the Long March 10 and Long March 10A configurations [13][16]. - The launch tower for the Long March 10 does not include a rotating platform, indicating improvements in manufacturing precision and allowing for quicker launch preparations [17][20]. Group 4: Future Developments - The Long March 10 rocket is expected to play a crucial role in China's lunar exploration efforts, with plans for further tests and the first flight anticipated in 2026 [20][21]. - The associated lunar missions, including the "Dream Boat" crewed spacecraft and the "Moon Landing" lander, are progressing on schedule, contributing to the goal of a successful lunar landing by 2030 [21].
