An experimental reusable rocket developed by the research and development arm of Honda Motor Company flew to an altitude of nearly 900 feet Tuesday, then landed with pinpoint precision at the carmaker's test facility in northern Japan.
The accomplishment may not sound like much, but it's important to put it into perspective. Honda's hopper is the first prototype rocket outside of the United States and China to complete a flight of this kind, demonstrating vertical takeoff and vertical landing technology that could underpin the development of a reusable launch vehicle.
While Tuesday's announcement by Honda was unexpected, the company has talked about rockets before. In 2021, Honda officials revealed they had been working on a rocket engine for at least two years. At the time, officials said a small satellite launch vehicle was part of Honda's roadmap.
The rocket Honda talked about in 2021 could put a payload of up to 1 metric ton into low-Earth orbit. It's unclear whether Honda is still targeting this sector of the launch market. Company officials then committed to supporting internal development work until about 2025 or 2026, when it would make a "go" or "no go" decision on whether to finish the project and field an operational rocket.
Developed in-house by Honda R&D Company, the rocket climbed vertically from a pedestal at the company's test site in southeastern Hokkaido, the northernmost of Japan's main islands. The vehicle reached an altitude of about 890 feet (271 meters). The vehicle descended to a nearby landing target and settled on its four landing legs just 15 inches (37 centimeters) from its aim point, according to Honda.
What's more, the rocket stood on its four landing legs for liftoff, then retracted the landing gear as it climbed into the sky. At its highest point, the vehicle extended aerodynamic fins akin to those used on SpaceX's reusable Falcon 9 and Super Heavy boosters. Moments before reaching the ground, the rocket folded the fins against its fuselage and deployed its four landing legs for touchdown. The flight lasted approximately 57 seconds.
The test rocket is small in stature, measuring less than 21 feet (6.3 meters) tall and about 2.8 feet (85 centimeters) in diameter. Fully fueled, the rocket weighed about 2,892 pounds (1,312 kilograms). Honda has been reticent about the rocket's engines, but the company's video of the test flight suggests the liquid-fueled engines consume cryogenic propellants, possibly a mixture of methane and liquid oxygen.
