H3-22 | Michibiki 5 (QZS-5)
Status: Failure | Launched: Dec 22, 2025 01:51 UTC
Failure reason: 2nd stage liquid hydrogen tank pressure abnormally start decreasing after fairing separation, leading up to 2nd stage 1st burn 27 seconds longer than planned & engine shutting down 1 second into 2nd burn. Payload stranded in LEO and re-entered shortly after.
