JAXA is investigating the details of the incident.



In July 2023, an explosion occurred during a combustion experiment of the Epsilon S’s engine at the Noshiro Rocket Testing Center in Akita Prefecture, leading JAXA to take countermeasures by covering the ignition device with heat-insulating material for the latest test.
