Japanese space start-up Interstellar Technologies Inc (IST) has successfully conducted a prototype rocket engine test using liquid biomethane (LBM) derived from cattle manure.
The “Static Fire Test” for the ZERO launch vehicle rocket at the Hokkaido Spaceport demonstrated the viability of environmentally friendly rocket fuel made from cow dung. Developed in collaboration with Air Water, the eco-friendly rocket fuel is produced through a regional circular supply chain in Hokkaido, where biogas from livestock manure is converted into LBM.
The successful test positions the company for its goal of launching small satellites into low-Earth orbit by 2025.
