科技日报：回收试错是中国航天进阶必修课

Core Viewpoint - The recent failures in rocket recovery by Chinese aerospace highlight the inherent high-risk nature of space exploration, emphasizing the need for continued experimentation and acceptance of trial and error in advancing technology [2][3]. Group 1: Recent Events - On December 23, China launched the Long March 12A rocket, but the first stage was not successfully recovered, with the cause under investigation [1]. - Just 20 days prior, Blue Arrow Aerospace's Zhuque-3 rocket also failed during the recovery phase [1]. Group 2: Industry Context - The recent setbacks have temporarily sidelined China's reusable rocket sector, which has seen rapid development in recent years, often overshadowing the high-risk attributes of space missions [2]. - The complexity of rocket recovery is likened to "throwing a needle from tens of thousands of meters and ensuring it lands in a predetermined hole," illustrating the significant challenges faced [2]. Group 3: Future Implications - The failures expose current technical shortcomings and underscore the difficulties ahead for China's space endeavors, with flight data from these tests being crucial for overcoming challenges and mastering key technologies [3]. - Acknowledging the risks and embracing trial and error is essential for progress in aerospace exploration, as each attempt contributes to the broader understanding and capability in the field [3].
