Japan Tests Experimental Reusable Rocket RV-X

The Japan Aerospace Exploration Agency (JAXA) completed the first lift-off and landing test of its prototype reusable rocket, RV-X, on 11 July 2026 at the Noshiro Rocket Testing Center in the Akita region of northeastern Japan. The test flight lasted about 40 seconds, with the rocket reaching an altitude of around 10 to 11 metres, moving horizontally for about 16 metres, and landing safely.

Reusable Rocket Technology

Reusable rockets are launch vehicles designed to return to Earth and fly again after recovery. The RV-X is 7.3 metres tall and 1.8 metres in diameter, and its engine is designed for about 100 launches. The prototype has already undergone more than 160 combustion tests.

JAXA’s RV-X Development Programme

JAXA uses the RV-X project to test technologies linked to lower launch costs and improved launch efficiency. Takashi Ito serves as the project manager for the reusable rocket programme. JAXA plans future RV-X tests at higher altitudes, with a target of around 100 metres.

International Reusable Launch Vehicle Projects

The RV-X test supports the development of CALLISTO, a joint reusable launch vehicle project involving France and Germany. CALLISTO is scheduled for a flight test in April 2027. The global space launch market includes companies such as SpaceX, which operates reusable launch systems.

Important Facts for Exams
