This engine of Japan's new small launcher explodes again during a crucial test

Japanese space development was recently shaken by a new technical failure. The explosion of the Epsilon S rocket's engine during a combustion test has raised concerns about the future of this flagship project. Although the incident caused no injuries or external damage, it represents a major setback for the Japanese space agency JAXA.

The incident at the heart of the space center

On November 26, 2024, the Tanegashima space center was the scene of a disturbing spectacle. An Epsilon S rocket engine exploded during a burn test, causing a fire and extensive damage to the test facility.

JAXA confirmed that the explosion occurred just 49 seconds after the start of the test scheduled to last two minutes. The engine was destroyed and debris was scattered throughout the test area.

A second worrying failure

This explosion marks the second consecutive failure for the Epsilon S engine, following a similar incident the previous year. This new setback raises questions about the reliability and safety of future launches.

Takayuki Imoto, project manager for the Epsilon S, expressed his disappointment during a press conference. We are sorry that we did not meet expectationshe said, emphasizing the need for a thorough investigation to determine the causes of the accident.

Impacts on the space program

The consequences of this explosion extend far beyond the walls of the test center. The Epsilon S development program could suffer significant delays, thus compromising the launch schedule initially planned for March.

JAXA is working to recover and analyze damaged parts to minimize program delay. However, repairs to the test facility could take several months, delaying future testing.

Strategic importance of the Epsilon S

The Epsilon S rocket plays a crucial role in Japan's space strategy. Designed to strengthen the country's position in the growing satellite launch market, it uses solid fuel to provide greater flexibility and mobility.

Japan is banking on the Epsilon S to ensure its autonomy in space development. Despite this incident, officials remain determined to continue the project.

Comparison with other projects

Japan has had successes and failures in its recent space projects. The much larger H3 rocket failed during its inaugural launch in February 2023, but has since completed three consecutive successful flights.

To better understand the evolution of Japanese space projects, the table below provides an overview of recent launches and their success.

An uncertain but promising future?

The development of the Epsilon S remains crucial for Japan, and efforts to overcome these technical challenges continue. The country must now prove its ability to correct mistakes and move forward.

The question remains : How will JAXA overcome these obstacles to make the Epsilon S a resounding success in the space domain?
