Japan tests prototype reusable rocket

Japan is advancing its reusable rocket technology with a successful test flight of the RV-X prototype. Launched from the Japan Aerospace Exploration Agency's (JAXA) Noširo testing site, the rocket reached an altitude of approximately 10 meters before landing, completing a 40-second flight.

This initiative is part of Japan's broader strategy to enhance the international competitiveness of its rocket industry. Reusable rockets are seen as crucial for reducing launch costs, as the most expensive component, the first stage, can be used multiple times. This contrasts with most rockets, which are designed for single use, leading to debris in orbit or the sea.

The RV-X, a joint development between JAXA and Mitsubishi Heavy Industries, measures 1.8 meters in diameter and 7.3 meters in length. It is equipped with an advanced durable engine and four shock-absorbing landing gears. JAXA, in collaboration with France and Germany on reusable rocket technology, plans to send the RV-X to an altitude of about 100 meters in future test flights.

Japan's efforts in space technology also include its H3 rocket, which had a successful launch in June after a previous mission to orbit a satellite ended unsuccessfully. The country is also observing advancements by competitors, such as SpaceX's use of its reusable Falcon 9 rocket since 2017 and China's recent successful landing of a reusable rocket, which could challenge U.S. dominance in the sector.
