Unusual cow dung sought after to fuel rockets.

In the race towards sustainable space exploration, Interstellar Technologies Inc (IST) has made a groundbreaking move by successfully testing a prototype rocket engine powered by liquid biomethane derived from cow dung. IST's recent static test of the ZERO rocket at the Hokkaido Spaceport's Launch Complex -0 yielded impressive results.

The rocket engine is powered by liquid bio-methane (LBM), produced from livestock dung collected from local dairy farms. Particularly, cow dung is considered a stable and efficient source for this energy. The 10-second test produced a mesmerizing green and orange flame.

Not only a significant achievement in the field of sustainable rocket fuel, but also a testament to ingenuity in using natural resources to expand space exploration capabilities. This is not just a major step forward but also a shining point in the space industry.

In collaboration with the Japanese-based partner Air Water, Interstellar Technologies Inc (IST) has initiated a unique supply chain in the Tokachi and Hokkaido regions. Here, biogas from livestock manure is processed into liquid bio-methane (LBM) to enhance innovation and sustainability. Local farmers, equipped with modern facilities on their farms, play a crucial role in the conversion of livestock dung into bioenergy, laying the foundation for environmentally-friendly rocket engines.

In addition to using bio-methane, IST's ZERO rocket also runs on liquid methane as propellant, optimizing costs and fuel efficiency, especially suitable for top partners like SpaceX. IST's simplified engine design, reducing components by 1/10 compared to traditional engines, is evidence of a commitment to cost-effectiveness and efficiency, showcasing an innovative approach similar to SpaceX.

The pintle injector, a key component controlling thrust fuel distribution, is the symbol of IST's dedication to optimal combustion efficiency. Active collaboration with the University of Tokyo and JAXA continues to elevate the ZERO rocket's combustion chamber to new heights, marking a significant step before the planned launch of a small satellite rocket in 2025.

Aiming to conquer space, Interstellar Technologies Inc (IST) presents an intriguing vision with the ZERO rocket project - an estimated product cost competitive at less than 800 million JPY per launch in mass production. This is not only a positive move to meet the growing demand for small satellite launch services, especially in the Asia-Pacific region. The project's success is not only a result of superiority in , but also a promise that livestock manure can contribute to carbon neutrality, proving that space exploration and environmental responsibility can harmoniously coexist.

IST's fundamental journey from pasture to space is not just a challenge but also a symbol of intelligent innovation bridging the gap between agriculture and modern space technology. It's not only a step in shaping our future on this planet but also a clear testament to the harmony between sustainable development and relentless enthusiasm for space exploration.
