Core Viewpoint - The Japan Ministry of Education, Culture, Sports, Science and Technology announced that the H3 rocket, carrying the sixth satellite of the Quasi-Zenith Satellite System, failed to deliver its payload to the intended orbit after launch [1][2]. Group 1: Launch Details - The H3 rocket was launched from the Tanegashima Space Center in Kagoshima Prefecture [1][2]. - The second-stage engine of the rocket experienced an abnormal shutdown shortly after launch [1][2]. - The launch of the "Rinri 5" satellite was initially scheduled for December 7 but was postponed due to detected anomalies in the rocket and ground facilities [1][2]. Group 2: Satellite System Objectives - The Japan Aerospace Exploration Agency (JAXA) aims to have a total of 11 positioning satellites in orbit to ensure redundancy in case of technical failures and to expand service coverage [1][2]. - Once the seven-satellite Quasi-Zenith Satellite System is fully operational, there will be continuous coverage of at least one satellite over Japan, with service extending to other regions in Asia and Oceania [1][2].
