TOKYO, Japan, June 17, 2025 – Honda R&D Co., Ltd., a research and development subsidiary of Honda Motor Co., Ltd., today conducted a launch and landing test of an experimental reusable rocket*1 (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 300 meters.

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 at 37cm of the target touchdown point, flight duration 56.6 sec), while obtaining data during the ascent and descent.

・Purpose:     Establishment of key technologies necessary for a reusable rocket
・Location:     Honda facility in Taiki Town*2, Hiroo District, Hokkaido Prefecture, Japan
・Date/Time:  June 17, 2025. Launch time: 16:15

*1 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.

*2 Taiki Town, located in southeastern Hokkaido, Japan, has been developing itself as a “space town” through the joint efforts of public and private sectors, and various aviation/space related tests are being conducted by a wide range of organizations including JAXA (Japan Aerospace Exploration Agency), businesses and universities.

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. 

  • A restricted area with a 1-kilometer radius was established. During the test, access to the area was restricted through the installation of signs and gates, as well as the deployment of security personnel.
  • The restricted area was defined by calculating the potential area where the rocket could fall to earth in the event of a thrust cut-off and by adding a sufficient buffer zone (safe distance calculated based on the guidelines set forth by the Cabinet Office of the Government of Japan) that would cover the potential area where a blast wave, debris dispersion, or fireballs could impact in the event of an explosion within the potential fall area.
  • The experimental rocket was equipped with a safety system to prevent deviation from a pre-defined flight corridor, speed and attitude conditions, ensuring no impact beyond the restricted area.

As announced in 2021, Honda has been pursuing research and development in the field of space technologies while viewing it as a place to take on challenges to realize the “dreams” and “potential” of people worldwide while leveraging its core technologies. Honda has the aim to enable people to transcend the constraints of time, place or ability and make people’s daily lives more enjoyable. Examples of Honda initiatives toward creating new value in the ultimate environment of outer space include research into a circulative renewable energy system, key robotic technologies for use in outer space and reusable rockets. 

Inspired by the dream of young Honda engineers who wanted to build rockets by utilizing core technologies amassed by Honda through the development of various products, such as combustion and control technologies, Honda started rocket research based on the belief that it has the potential to contribute more to people’s daily lives by launching satellites with its own rockets, that could lead to various services*3 that are also compatible with other Honda business.

In today’s world, vast amounts of data are consumed, with the growing expectation for greater utilization of a data system in outer space through expanded use of satellites. In light of this trend, the need for satellite launch rockets is also expected to increase in the coming years.

In this market environment, Honda has chosen to take on the technological challenge of developing reusable rockets by utilizing Honda technologies amassed in the development of various products and automated driving systems, based on a belief that reusable rockets will contribute to achieving sustainable transportation.

Although Honda rocket research is still in the fundamental research phase, and no decisions have been made regarding commercialization of these rocket technologies, Honda will continue making progress in the fundamental research with a technology development goal of realizing technological capability to enable a suborbital launch by 2029. 

“We are pleased that Honda has made another step forward in our research on reusable rockets with this successful completion of a launch and landing test. We believe that rocket research is a meaningful endeavor that leverages Honda’s technological strengths. Honda will continue to take on new challenges—not only to offer our customers various services and value through our products, while addressing environmental and safety issues, but also to continue creating new value which will make people’s time and place more enjoyable.”

*3 Examples include remote sensing to monitor Earth conditions such as global warming and extreme weather, as well as satellite constellations that enable wide-area communication, which is an essential component for connected features of mobility products.

      It's interesting how I couldn't tell whether the rocket was 1m tall or 10m tall in this video. Turns out it's actually 6m tall per the link.

      For some reason the landing of that reminded me of the Eagle from Space:1999 - there was something different in the ballistics of it compared to SpaceX and Blue Origin. Fantastic to see, thanks for the video link.

      What is the steam cloud for after landing?

      • By 420official 2025-06-1719:471 reply

        It's liquid propellant being vented, the fuel is under extreme pressure so when its released it immediately expands to a gas. I don't know that Honda has said what their propellant is, but it's probably liquid hydrogen and liquid oxygen.

        • By perihelions 2025-06-1719:51

          I think it's unlikely they'd deal with the difficulties of liquid hydrogen on something this small (and not performance-sensitive).

          It might just be ethanol/oxygen.

      Great clean video link thanks, but I cant work out the scale, first it looks like a toy rocket, then from the distance shot it looks huge, like spaceX huge, and then landing it looks quite small again, especially with the lawn sprinklers.

      But an impressively smooth landing regardless, and I would imagine maybe harder the smaller the rocket is.

      • By perihelions 2025-06-1719:051 reply

        It's much smaller than other suborbital hop vehicles. If it's 6.3 meters, the smallest Starhopper was 18 meters; Blue Shepherd 19 m; China's Hyperbola-2Y 17 m; the Zhuque-3 VTVL test vehicle 18.3 m. Also the Grasshopper from 2012 was 32 m and even 1993's DC-X was 12 m.

          You likely weren't being exhaustive in your listing, but I first started watching aerospace development with Armadillo Aerospace, and some of their rockets were much smaller. Their largest one was still shorter than the dc-x.

      I'm accustomed to seeing large plumes of chemicals coming out the other end in my minds eye when I think about rocket launches. This looks "clean" coming out the exhaust.

      Why is that? Is it due to the nature of chemicals it uses?

      • By nine_k 2025-06-1718:15

        Soot means carbon-rich fuel, like RP1, and a very fuel-rich mix. Most launches I ever saw had basically zero soot, and a clean exhaust of a well-balanced fuel / oxidizer mix.

        Military rockets, and solid-fuel boosters like the kind the Shuttles used to use, indeed produce very visible exhaust, because they use heavy fuels, and sometimes heavier oxidizers, like nitric acid. This is because they need to be in the fueled state for a long time, ready to launch in seconds; this excludes more efficient but finicky cryogenic fuels used by large commercial rockets.

        The large plumes that you usually see the first few seconds when a rocket is blasting off a launch pad are mostly water vapor. The launch pad would be destroyed by the exhaust were it not cooled during the launch by large amounts of water, which gets evaporated instead of the concrete.

      • By fogh1 2025-06-1718:01

        Basically yes, other rockets might burn chemicals that create more soot. This one seemingly doesn’t.

      Watching the video, when the rocket lifted-off, it stood on a couple small risers. When it landed, the risers were gone. Did someone run out there and grab them?

      • By feoren 2025-06-1718:422 reply

        Despite the other comments, the landing spot is clearly the same as where it took off. Take a screenshot at 0:09 and one at 0:48 and you can see that it's most certainly the same pad. The camera has moved slightly to the left on the landing, that's all.

        Someone must have run out and grabbed the risers.

      • By pavel_lishin 2025-06-1718:25

        It may not have landed on the same pad it took off from.

      • By Kye 2025-06-1718:241 reply

        I think the landing spot is different from where it took off from. The trees in the landing shot weren't there in the takeoff shot.

        • By sprkv5 2025-06-1718:421 reply

          the lift off spot is at the edge of the launch pad, whereas the landing spot is at the center of the launch pad.

          [edit] the camera angle and the camera height from the ground is different as well between the lift off and landing.

      The feet landing extension reminds me of the Delta Clipper DC-X rocket, the first reusable VTOL rocket from 30+ years ago: https://www.youtube.com/watch?v=wv9n9Casp1o

      I wonder if that's the optimal design for VTOL rocket landers? Or is that more particular to smaller lighter rockets and eventually you need heavier duty options for bigger rockets?

      Also the DC-X was eventually intended to be single-stage-to-orbit (SSTO). Do any of these reusable rockets plan on being SSTO? Whether from Space-X/Blue Origin or this or the Chinese ones? SSTO is where you're going to dramatically change the economics of rockets, as you now only have to worry about refueling when launching satellites, instead of using an expendable second stage..

    For reference, Rocket Lab's Electron has a wet mass of 13,000 kg. This rocket is much smaller at 1,312 kg wet mass.

        k kg is a funny unit... Much more readable than Mg of course. Tonnes would also work...

          Tonne is unfortunately overloaded, the US and the UK have their own versions, but for the rest of the world is on metric, and a tonne is 1000 kg. The Falcon 9 weighing "433 t" reads way more elegantly to me.

          Starship is 1.2 kilotons, but I feel like quoting rockets in kilotons might cause some confusion.

          “Mg” wouldn't even be valid since the SI unit is the kilogram. But yeah, using tons is the sensible choice.
