Japan's Ministry of Education, Culture, Sports, Science and Technology held a conference on the 30th regarding the failure of the “H3 rocket 8” launch last year. The final report adopted at the conference indicated that the base of the rocket carrying the satellite had a gap due to internal detachment. The gap widened during the rocket flight and caused the base to be damaged as the main reason for the launch failure. The report was compiled by the Japan Aerospace Exploration Agency. According to reports, soon after the separation of the satellite fairing began, the base of the satellite was damaged. The investigation determined that the main reason for the base damage was that the base was internally peeled off during production, and the gap that appeared was further expanded under the impact of the fairing when the fairing was separated. According to the report, in the future, methods such as resin filling or fastener connections can be used to avoid the risk of peeling. Japan launched the “H3 Rocket 8” on December 22, 2025. The rocket's second-stage engine burning stopped early, the satellite on board failed to enter the scheduled orbit, and the launch mission failed.
