# Isro tests LME1100 methane engine gas generator, eyes 2040 lunar landing 2026-10-20T03:51:33+00:00 | Governance | Indian Opinion Desk Corroboration: 2 independent outlets Isro has conducted the first ignition test of the full-scale gas generator for its 1,100-kN LOX-Methane LME1100 engine, marking a milestone in the development of the agency's Next Generation Launch Vehicle and a future human-rated heavy-lift vehicle for a crewed lunar landing planned around 2040. The test took place on 9 October at Isro's Propulsion Complex in Mahendragiri, Tamil Nadu. The complete engine is targeted to be ready by mid-2027, followed by hot-fire qualification tests at varying thrust levels. Isro has also completed the design of a more powerful 2,400-kN LOX-Methane engine based on the full-flow staged combustion cycle, the same propulsion architecture used by SpaceX's Raptor engines. More than 70 per cent of the LME1100's components have been produced using additive manufacturing (3D printing) with Indian industrial partners. Isro began methane propulsion work in 2019 with a 20-tonne-thrust technology demonstrator, formally launching the LME1100 programme in 2023. The next major milestone is the integrated engine's completion by mid-2027. ## Indian Opinion Analysis Both sources report the same LME1100 gas-generator test and the 2,400-kN design as uniform facts from Isro. Deccan Chronicle opens with the engine as a milestone for India's ‘future lunar missions’ and closes on crewed lunar exploration, framing the news inside the agency's own long-term roadmap. India Today leads with the SpaceX comparison, ‘SpaceX-style methane rocket engine’ in the headline and ‘technology also employed by SpaceX’s Starship’, and uses a separate ‘Why is this a big deal’ section to underline the geopolitical and reusable-rocket angle. The difference is one of context: Deccan Chronicle keeps the frame inside Isro’s programme narrative, while India Today draws an external competitive benchmark. The balanced reading is that the same technical milestone is being reported with distinct foregrounds, indigenous capability vs. global parity. The next named milestone is the complete engine rollout by mid-2027. ## Coverage Coverage: 2 sources, 2 neutral - deccanchronicle.com (neutral report) Frames test as forward step in Isro's own programme roadmap - indiatoday.in (neutral report) Leads with SpaceX comparison and reusable-rocket significance This brief was synthesised by AI from the 2 sources linked above, so one read covers every framing they carry.
