A short hop confirmed RV-X recovery systems, but engineers warn higher altitude tests will be needed to prove operational reuse.
In Tokyo, the experimental Japanese reusable rocket RV-X conducted its first test flight, after which the rocket safely landed. This marks an important step in reducing launch costs and boosting competitiveness on the global space market, where SpaceX dominates.
First Flight and Technical Details
RV-X lifted off, hovered, and moved horizontally for a distance of 16 meters, maintaining a vertical orientation before landing at Noshiro Testing Center in the northeast region of Japan. Live coverage was provided by NVS – an online community of space enthusiasts.
According to Takashi Ito, JAXA’s reusable rocket project manager, the flight, lasting less than a minute, went as planned: the rocket rose to 11 meters, then transitioned to a horizontal trajectory for 16 meters, after which it landed safely.
Context: Competition and the Economics of Launches
Japan is striving to catch up to the technology that SpaceX, led by Elon Musk, has been using for several years to reduce the cost of delivering payloads into space.
The flight on Saturday marked a step forward in developing a cheaper replacement for the current H3 mainline, which has a higher success rate than the previous H-2A but still needs further cost reductions to be globally competitive.
Partnership and Future Plans
RV-X is being developed jointly by JAXA and Mitsubishi Heavy Industries; the rocket’s diameter is 1.8 meters, and its length is 7.3 meters. It is equipped with a durable engine and four shock-absorbing landing legs.
According to Ito, the engine withstood 165 burn tests. The Japanese team also plans future tests at an altitude of around 100 meters.
JAXA continues to collaborate with France and Germany in the development of reusable rockets. The Japanese government emphasizes that a stable and commercially competitive space transportation system is key to the space program and national security.
In the future, RV-X tests are expected to support cost reductions and the development of a full-fledged reusable system, enabling Japan to expand its capabilities on the global space market and provide more affordable access to space for the country.
