Static firing test for the upper stage sub-size motor

On September 30, JAXA performed the ground firing test of the sub-size motor (M-34SIM-3) for the Epsilon Launch Vehicle upper stage at the Noshiro Rocket Testing Center. The test mainly aims to verify the insulation material on the upper motor nozzle that is currently under development.
Through this test, we are steadily progressing with the Epsilon development while confirming the insulation function of the upper motor nozzle part based on the test results and maintaining and inheriting the already acquired solid motor static firing test technology.
