Hybrid power transforms
Space Transportation
The non-explosive nature of hybrid rockets enables both safety and high-frequency launches. Unlike conventional liquid or solid rockets, the absence of explosion risk simplifies preparation, allowing safe launches anytime, as often as needed.
This combination of “safety × high frequency of launches” will revolutionize conventional space transportation norms, realizing a world where space transportation can be executed whenever desired.
Turning Research into Real-World Solutions
A Decade of Research Excellence
The technical expertise cultivated over a decade of research and the systems we built and operated ourselves. This accumulated knowledge is our greatest strength. It’s precisely because our unique structure has been verified in practice, not just theory, that our certainty in societal implementation stands apart. We deliver research outcomes to the world as real businesses. That is the true value of a university-spinoff startup.
Driving Japan’s Space Industry to the Forefront of Global Competition
The challenges facing small satellite manufacturers are launch delays and market competition. Currently, SpaceX launches have a two-year wait, leading to lost growth opportunities and diminished competitive advantage. Minato Rocket accelerates satellite manufacturers’ business growth and market competitiveness by enabling rapid, high-frequency launches.
