The H3 F8 mission used the H3 24L configuration that was designed to place the 4,000 kg Michibiki No. 5 satellite into a specific transfer orbit.
Both Michibiki No. 5 and the H3 F8 first stage are believed to have impacted the Pacific Ocean near Minamitorishima.
The loss of Michibiki No. 5 stalls Japan’s effort to complete a seven-satellite sovereign Positioning, Navigation, and Timing (PNT) network that was slated for completion by March 2026 to reduce reliance on U.S. GPS.
JAXA's investigation found that during fairing separation physical contact or debris damaged the mounting section for Michibiki No. 5 (QZS-5).
H3 rocket No. 8 failed to place the Quasi-Zenith Satellite System satellite Michibiki-5 into its planned orbit.
JAXA will continue investigating the cause of the launch failure, focusing on the event immediately after fairing separation and working with organizations related to Michibiki-5 while considering all possibilities.
JAXA has postponed the launch of MICHIBIKI No. 7, part of the Quasi-Zenith Satellite System.
MICHIBIKI No. 7 is part of the Quasi-Zenith Satellite System.
MICHIBIKI No. 7 was scheduled to be launched aboard the 9th H3 Launch Vehicle.
MICHIBIKI No. 7 was scheduled to launch aboard the 9th H3 Launch Vehicle.
The launch of MICHIBIKI No. 7 has been postponed.
The launch failure resulted from the inability to release the sixth satellite of the seven-unit 'Michibiki' system into orbit.
The H3 rocket No. 8 was carrying the quasi-zenith satellite system Michibiki No. 5, and the current status of this satellite is under investigation.
The Cabinet Office is sending commands to the Michibiki No. 5 satellite in the predicted communication time frame but has not received any response as of now.
The H3 No. 8 rocket lifted off but its second-stage engine shut down early before inserting the Quasi-Zenith Satellite System spacecraft Michibiki-5 into orbit.
JAXA explained that while a separation signal was sent from the rocket, the back signal indicating successful separation of the satellite (MICHIBIKI) was not received.
JAXA's Director and Launch Implementation Manager Masashi Okada is currently verifying if the satellite (MICHIBIKI) was successfully separated.
Japan Aerospace Exploration Agency (JAXA) announced on December 22 that the H3 rocket's launch failed and may have resulted in the loss of the Quasi-Zenith Satellite 'MICHIBIKI' No. 5.
MICHIBIKI No. 5 will be launched aboard the 8th H3 Launch Vehicle.
MICHIBIKI No. 5 is part of the Quasi-Zenith Satellite System.
