- Japan’s JAXA suspends Epsilon S rocket engine test after an explosion during the trial at the Tanegashima Space Center
- The cause of the explosion remains under investigation as the space agency works to ensure the safety of its future launches
What happened
Japan’s space agency aborted an engine test for the Epsilon S rocket on Tuesday (November 26) after it exploded and caught fire, a repeated failure that will likely push the rocket’s debut launch beyond the March-end target and delay the national space programme.
The test was being conducted at Japan’s Tanegashima Space Center, where the Epsilon S rocket is being developed to carry out satellite missions. The explosion took place during a routine engine test designed to verify the rocket’s performance and reliability. The space agency immediately halted the testing and launched an investigation to determine the cause of the explosion.
While no one was injured and the fire was put out within an hour, the blast damaged the facility, and the cause remains unclear, JAXA’s Epsilon project manager Takayuki Imoto told a media briefing. “We are sorry that we couldn’t meet everyone’s expectations…but a silver lining was that we found (the issue) at a ground test, before putting it for a flight”, Imoto said, adding it will likely take at least several months to investigate the cause and take necessary countermeasures.

What it’s important
This explosion serves as a stark reminder of the risks inherent in the space industry, even for advanced programs like Japan’s JAXA. While failures in rocket testing are part of the development process, the stakes in space exploration are high, and the incident underscores the challenge of achieving both safety and innovation in an industry defined by precision and risk. The broader context of this incident is particularly important when we consider the global competition in space, especially with the increasing involvement of private companies.
For example, smaller private companies like Rocket Lab, a New Zealand-based startup, have been making strides with their Electron rocket, which focuses on more frequent, small satellite launches. Unlike large government agencies, Rocket Lab’s relatively agile operations allow for faster iterations, albeit with more financial risk. However, despite its smaller scale, Rocket Lab has learned from similar setbacks and has managed to use failures as opportunities to refine its technology. Such examples demonstrate that the space industry is increasingly being shaped by the pace and adaptability of private firms, which often face fewer bureaucratic hurdles than government agencies like JAXA.
