Honda Conducts Successful Launch and Landing Test of Experimental Reusable Rocket

Honda R&D, a research and development subsidiary of Honda Motor Co., Ltd., today conducted a launch and landing test of an experimental reusable rocket (6.3 m in length, 85 cm in diameter, 900 kg dry weight/1,312 kg wet weight) developed independently by Honda. The test was completed successfully; the first time Honda landed a rocket after reaching an altitude of nearly 300 meters. A reusable rocket, also known as a reusable launch vehicle (RLV), is a type of rocket that, unlike a conventional expendable launch vehicle (ELV), can be used repeatedly in a short period of time. A reusable rocket is launched in a vertical position, reaches an altitude of around 100 kilometers, and then lands back on earth while maintaining a vertical position.


This test marked the first launch and landing test conducted by Honda with an aim to demonstrate key technologies essential for rocket reusability, such as flight stability during ascent and descent, as well as landing capability. Through this successful test, Honda achieved its intended rocket behaviors for the launch and landing (reaching an altitude of 271.4 m, and landing within 37cm of the target touchdown point, with a flight duration of 56.6 sec), while obtaining data during the ascent and descent.

Since 2024, Honda has been safely conducting engine combustion tests and hovering tests for its reusable rockets in Taiki Town in Hiroo District, Hokkaido, Japan. As with all previous tests, Honda conducted this launch and landing test while placing the highest priority on safety and with the understanding and cooperation of local authorities and residents.
