AI Summary

Rocket fuel remains a notable fossil‑fuel exception as launches increase to near‑daily frequency. SpaceX is constructing new natural‑gas pipelines to produce its own methane‑based propellant, aiming to support the launch of many thousands of rockets in coming years. The company’s approach relies on processing natural gas to strip nitrogen and other impurities, then liquefying the methane and mixing it with liquid oxygen to create a high‑energy propellant. While not all rockets use methane, several aerospace firms, including SpaceX, have adopted it in pursuit of space dominance.
