The Japanese Aerospace Exploration Agency (JAXA) recorded a failure of the launch of the H3 carrier rocket, which was meant to place the navigation satellite QZS-5 into orbit. The reason was a problem with the second-stage engine.<\/p>\n
According to a JAXA press release, the morning of December 22, 2025 was marked by an attempt to launch the eighth Michibiki No. 5 mission from the Tanegashima Space Center. However, the second-stage engine failed and shut down prematurely.<\/p>\n
\n\u201cAs a result, QZS-5 could not be placed into its planned orbit, and the launch failed\u201d<\/p>\n
\u2013 according to a JAXA statement\n<\/p><\/blockquote>\n
Timeline of events and consequences<\/p>\n
Shortly before this, Japan had also faced difficulties during launches of its flagship H3 rocket. The H3 rocket, developed by Mitsubishi Heavy Industries, first failed during a previous attempt in 2023, but later completed six successful flights.<\/p>\n
Typically, such failed launches lead to lengthy investigations that can delay the development of the national space program and affect plans to upgrade the on-orbit navigation segment.<\/p>\n
Additionally, it was previously on December 17 that the launch of the eighth rocket was canceled due to an anomaly detected in the water-cooling system at the launch site.<\/p>\n
Such an event highlights the technical challenges facing Japan\u2019s space program, but the country continues to work on improving the systems and preparing for future flights.<\/p>\n
