Mitsubishi Identifies H3 Rocket Failure Cause, Targets Early 2024 Return-to-Flight
Mitsubishi Heavy Industries (MHI) and JAXA have pinpointed the cause of the H3 rocket's inaugural launch failure on March 7. An electrical issue in the second-stage engine's ignition system is believed to have prevented it from firing. Investigators suspect a short circuit or overcurrent occurred moments after stage separation. The failure led to the loss of the ALOS-3 Earth observation satellite. With the root cause now understood, MHI is implementing corrective measures and is targeting a second launch attempt by March 2024.
