日媒表示发射失败的H3火箭整流罩分离异常

Core Viewpoint - The H3 rocket launch failure on February 22 was attributed to an anomaly during the fairing separation and a continuous drop in pressure in the liquid hydrogen fuel tank of the second-stage engine, leading to an investigation into the entire system [1]. Group 1: Launch Failure Details - The H3 rocket experienced an abnormality during fairing separation approximately 3 minutes and 40 seconds after launch [1]. - The pressure in the liquid hydrogen fuel tank of the second-stage engine began to decline continuously around 3 minutes and 20 seconds post-launch, raising concerns about its relation to the premature shutdown of the engine [1]. Group 2: Future Implications - The head of the H3 project team stated that no further launches can occur until the cause of the failure is identified and countermeasures are implemented, indicating a comprehensive review of the entire system is necessary [1]. - Japanese media suggests that the recovery of the H3 rocket for future launches may take a considerable amount of time, potentially impacting planned missions including the Quasi-Zenith Satellite System, the next-generation HTV-X cargo spacecraft, and the Mars satellite probe, all scheduled for the fiscal year 2026 [1].
