Engine for Japan’s new Epsilon-S rocket explodes during static fire test
For the second time in a row an engine for Japan’s new Epsilon-S rocket has exploded during a static fire test.
The test was conducted inside of the restricted area at Japan’s Tanegashima Space Center in southwestern Japan, and the Japan Aerospace Exploration Agency is investigating, Chief Cabinet Secretary Yoshimasa Hayashi told reporters.
An Epsilon project manager, Takayuki Imoto, told an online press conference from Tanegashina that the explosion occurred 49 seconds into the planned two-minute test, causing fire and scattering broken parts of the engine and damaging the facility.
The Epsilon-S is being built by Japan’s space agency JAXA. It is intended to replace the solid-fueled Epsilon rocket that was initially conceived in 2013 to lower launch costs and provide JAXA with a rocket that could complete with the many new smallsat rocket startups worldwide. That rocket however only launched six times and never achieved its goals. JAXA had been targeting March for the first launch of Epsilon-S, but that is now unlikely, especially considering these two engine failures during tests.
