Japan tests reusable rocket prototype in breakthrough trial

Japan has successfully tested a prototype reusable rocket, marking progress in its efforts to develop cost-efficient launch technology and expand its space capabilities.

The Japan Aerospace Exploration Agency (JAXA) said its RV-X rocket reached an altitude of about 11 metres, travelled approximately 16 metres horizontally, and landed safely after a flight lasting around 40 seconds. The test was conducted at JAXA’s facility in Noshiro, Akita Prefecture, Kyodo News reported.

JAXA said the trial will support the development of the Callisto reusable launch vehicle, a joint project with France and Germany. The Callisto vehicle, which uses the same engine as the RV-X, is scheduled for a flight test next April and will attempt a landing from a significantly greater height than in the latest trial.

According to the agency, the RV-X prototype measures about 7.3 metres in length and 1.8 metres in diameter, and is equipped with four landing legs.

Japan is pursuing reusable launch technology as its flagship H3 rocket remains expendable, with each unit designed for a single use. Reusable systems allow boosters to be recovered and flown multiple times, reducing manufacturing and launch costs while enabling more frequent missions.

Efforts to develop such technology have also extended to the private sector. Last year, Honda R&D Co., a subsidiary of Honda Motor Co., conducted Japan’s first successful reusable rocket flight test by a private company.

Globally, reusable rocket landings for orbital launches were pioneered by Elon Musk’s SpaceX, while China has since become the second country after the United States to develop reliable reusable rocket technology.
