Core Viewpoint - The successful launch of 17 low Earth orbit satellites for satellite internet by the Long March 8A rocket marks a significant achievement in China's commercial space industry [1] Group 1 - The launch took place at 7:26 AM on December 26 at the Hainan commercial space launch site [1] - The satellites successfully entered their designated orbits, indicating the mission's overall success [1]

Core Viewpoint - The Japan Aerospace Exploration Agency (JAXA) reported that the navigation satellite "Yinlu 5" and the H3 rocket, which failed to launch on December 22, are likely to have fallen into the Earth's atmosphere, resulting in the loss of the satellite [1] Group 1: Launch Failure Details - The preliminary investigation revealed that after the rocket's launch, the satellite fairing separated, and the pressure in the second-stage liquid hydrogen fuel tank began to drop, reaching only about 65% of the normal combustion pressure by the time of the first burn's termination [1] - The first burn lasted approximately 24 seconds longer than planned, and due to further decreases in engine intake pressure, the second burn failed to achieve stable combustion and was terminated prematurely [1] Group 2: Official Confirmation - The Japanese Cabinet Office confirmed the loss of the "Yinlu 5" satellite and stated that the second stage of the rocket had entered the Earth's atmosphere [1] - The Cabinet Office's space policy minister, Kimi Onoda, acknowledged the confirmation from JAXA regarding the loss of the satellite [1]

Group 1 - The first commercial launch of South Korea's rocket "HanKwang-Nano" ended in failure after it caught fire shortly after takeoff at the Alcântara Launch Center in Brazil [1] - The rocket experienced an anomaly 1 minute and 40 seconds after launch, resulting in it transforming into a fireball, suspected to be an explosion [1] - The rocket was launched by the South Korean private aerospace company INNOSPACE, and the company's stock price plummeted immediately following the launch failure [1] Group 2 - The payload of the failed launch included five satellites [1] - The launch was delayed on the day of the event due to rain and had previously been postponed twice [1]

Core Viewpoint - Japan's H3 rocket launch on December 22 failed due to the premature shutdown of the second-stage engine, preventing the satellite from reaching its intended orbit [1] Group 1: Launch Details - The H3 rocket was launched from the Tanegashima Space Center at 10:51 AM local time, carrying the Quasi-Zenith Satellite System "Michibiki 5" [1] - The launch was initially scheduled for December 7 but was postponed to December 17 due to an anomaly in the inertial measurement unit [1] - On December 17, the launch was again halted due to an issue with the cooling water injection system [1] Group 2: Implications and Responses - The Japanese Minister of Education, Culture, Sports, Science and Technology, Yohei Matsumoto, has instructed the Ministry to collaborate with relevant departments to address the issue and work with JAXA to investigate the cause [1] - The failure of the H3 rocket's second launch marks a significant setback for Japan's space industry, following a previous failure in March 2023 due to an electrical system anomaly [1]

Core Viewpoint - The Japanese government confirmed the failure of the "Quasi-Zenith Satellite System" satellite "Michibiki 5" launched on December 22, 2023, due to the H3 rocket's second-stage engine burning prematurely, marking another setback for Japan's domestic launch capabilities following the H3 rocket's previous failure in March 2023 [1][2]. Group 1: Launch Failure Details - The H3 rocket's second-stage engine failed to ignite properly, leading to the satellite not reaching its intended orbit [1]. - This incident follows a previous failure in March 2023, where the H3 rocket was also unable to complete its mission due to an electrical system anomaly [2]. Group 2: Implications for Japan's Space Program - The failure of the "Michibiki 5" satellite launch may delay Japan's plans to achieve a fully independent navigation system, as the satellite was intended to be the sixth in a series that aims to reduce reliance on foreign GPS systems [1]. - The H3 rocket has now experienced two failures out of seven launches, which is a significant concern compared to the 98% success rate of its predecessor, the H2A rocket [2].

据日本媒体报道，此次火箭搭载的"引路"卫星是具备类似GPS定位功能的人造卫星，其作用包括提升智能手机等设备的位置信息精度，以及在电波无法覆 盖的区域发布紧急地震速报等。日本政府计划通过一系列发射构建起无需依赖国外卫星即可提供位置信息的7星体系。 当天10时51分左右，日本H3火箭8号机从鹿儿岛县种子岛宇宙中心发射升空。火箭上搭载有日本准天顶卫星系统的"引路5号"卫星。 此次发射任务最初定于12月7日进行，由于运载火箭第二级箭体搭载的惯性测量单元出现异常而被推迟。17日，发射又因即将点火时冷却水注水设备发生 异常而被紧急叫停。 每经编辑｜程鹏 潘海福 今天（12月22日）上午，日本新一代主力运载火箭"H3"火箭的8号机从鹿儿岛县种子岛宇宙中心发射升空。火箭上搭载有日本准天顶卫星系统的"引路5"号 卫星。 当地时间22日，日本文部科学省当天发布消息称，H3火箭8号机发射失败，火箭上搭载的卫星未能进入预定轨道。日本宇宙航空研究开发机构22日发射一 枚H3火箭，火箭在飞行途中第二级发动机燃烧提前停止。 每日经济新闻综合自央视新闻、@CCTV国际时讯 编辑|程鹏 潘海福 校对|陈柯名 封面图片来源：截图 ...
