Japanese Private Rocket Fails Again Shortly After Liftoff

Kairos 2 lifted off at 11 a.m. local time from Spaceport Kii in Wakayama Prefecture, aiming to make Space One the first private Japanese company to reach orbit. However, the 18-meter-tall rocket began tumbling shortly after liftoff. About three minutes into the flight, at an altitude of 100 kilometers, the mission was terminated due to anomalies in the first-stage engines and trajectory. The rocket was carrying five payloads, including satellites developed by Japanese companies, a Taiwanese organization, and high school students.

Two Attempts, Two Failures

This was the second failed launch for Space One’s Kairos series. In March 2024, the first Kairos rocket was destroyed shortly after leaving the launch pad when its flight termination system detected a velocity anomaly. While no personnel or facilities were harmed, debris from the explosion damaged the launch site. Designed to carry payloads of up to 250 kilograms to low Earth orbit, the Kairos rocket is part of Japan’s effort to boost its competitiveness in the small launch market.

Broader Challenges in Japanese Spaceflight

Space One’s struggles are not isolated. Japan’s national space agency, JAXA, has faced its own setbacks, including an engine explosion during a test of the new Epsilon S rocket in November 2024. A similar incident occurred in July 2023, raising concerns about the reliability and competitiveness of Japan’s space industry in an increasingly crowded global market.

Future Plans for Recovery

Following the failure, Space One issued a statement apologizing to its customers and supporters. The company pledged to investigate the incident thoroughly and to continue developing the Kairos rocket to support the expansion of the private space sector. Space One remains committed to achieving success and contributing to Japan’s presence in the global space industry.

The repeated failures of the Kairos rocket highlight the inherent challenges faced by private space ventures. Despite these setbacks, Space One remains committed to addressing the issues and pursuing future launches. Success in such endeavors could play a pivotal role in bolstering Japan’s competitiveness in the global space industry.
