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.

QZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation.
