Isro Tests Methane Rocket Engine Similar to SpaceX-Style Tech: Why It's a Big Deal
What Happened?
Isro successfully ignited its LME-1100 methane engine's gas generator, advancing India's heavy-lift rocket and lunar mission plans. The complete engine is set for 2027.
Key points
- Isro ignited the gas generator of its LME-1100 methane engine on October 9, 2026.
- The complete engine is expected to be ready by mid-2027 for hot-fire tests.
- Isro's LME-1100 engine uses a gas-generator cycle, while a proposed 2,400-kilonewton engine will use a full-flow staged combustion cycle.
- Methane is considered a cleaner rocket fuel and may be produced using Martian resources.
- Over 70% of the LME-1100's components are made using 3D printing.
Key insights
- The successful ignition test is a significant milestone for India's space ambitions.
- Developing methane engines may reduce reliance on traditional rocket fuels.
- Isro's advancements could position India as a competitive player in the global space industry.
Why it matters
The development of methane propulsion could enhance India's capabilities for future space missions.
