On the morning of the 23rd, the Japan Aerospace Exploration Agency conducted a combustion test on the second-stage engine of the new solid rocket “Epsilon S”. Following two failed tests in 2023 and 2024, the engine was replaced and the carrying capacity target was lowered in this test. At 9:00 local time on the 23rd, JAXA began carrying out ground combustion tests for the second stage engine of the “Epsilon S” rocket at the Tanegashima Space Center in southern Kagoshima Prefecture. Live footage from JAXA's official social media account shows that the engine ignited, flames and smoke erupted, and the test ended after burning for about two minutes, completing the target.
