Fire and Explosion Disrupt Japan's Epsilon S Rocket Engine Test

A combustion test for Japan's next-generation small rocket ended in flames, marking the second failure in its development and raising questions about its readiness for launch.

The Epsilon S rocket's second-stage engine caught fire and exploded during a combustion test at Tanegashima Space Center in Japan, with no injuries reported.
The test, planned to last 120 seconds, was halted roughly 30 seconds in after an explosion sent debris flying toward the sea, according to eyewitnesses and footage from NHK.
This marks the second engine failure for the Epsilon S, following a similar incident in July 2023 attributed to ignition system damage, despite corrective measures being implemented since then.
The Epsilon S rocket is a key part of Japan's strategy to compete in the growing satellite launch market, but its debut flight, initially scheduled by March 2025, now faces likely delays.
Japan's space agency, JAXA, has launched an investigation into the incident, emphasizing the importance of the rocket for the nation's space development and autonomy.
