Drugi stopień LE-5B-3 zawiódł.
Komunikat JAXA:Sądząc, że rakieta raczej nie zakończy swojej misji, około 10:52 wysłano sygnał zniszczenia.

satelitę Daichi-3 (ALOS-3, Advanced Optical Earth Observation Satellite).
W T+5' 17" miało dojść do uruchomienia silnika drugiego stopnia, jednak to nie nastąpiło i kontrola lotu wydała polecenie zniszczenia rakiety.http://lk.astronautilus.pl/n230301.htm#03Centrum kontroli naziemnej wydało rozkaz zniszczenia drugiego stopnia rakiety nośnej H3, w tym satelity ALOS 3. Misja kończy się tym samym definitywnym niepowodzeniem.

"So what happened? It's something we will have to investigate looking at all the data."

Live footage showed the 63-meter expendable rocket soaring up into the sky with bright yellow flames spewed from two side-mounted solid rocket boosters. The side boosters were jettisoned about two minutes after liftoff and stage separation took place about five minutes after liftoff, according to telemetry. However, the second-stage engine’s ignition was not confirmed and the its velocity was seen declining as the rocket’s altitude reached about 620 kilometers. JAXA then announced that the rocket was ordered to self-destruct.

Engineers discovered cracked rotor blades in the LE-9 engine’s fuel turbopump after hotfire testing in 2020, and found holes in the internal wall of the engine’s combustion chamber. The engine development team redesigned the turbine blades and the fuel and oxidizer turbopumps to resolve the problems, then performed more hotfire tests before clearing the H3 rocket for its inaugural test flight.
