Context:

On August 23, 2025, ISRO Chairman V. Narayanan announced that the space agency is building its heaviest rocket ever, the Lunar Module Launch Vehicle (LMLV).

About Lunar Module Launch Vehicle (LMLV):

The Lunar Module Launch Vehicle (LMLV) is India’s most ambitious rocket under development by ISRO, set to be operational by 2035.

·        It is designed to support crewed lunar missions by 2040 and to launch heavy components of India’s planned Bharatiya Antariksh Station (BAS).

·        With a payload capacity of 80 tonnes to Low Earth Orbit (LEO) and 27 tonnes to the Moon, LMLV will be ISRO’s most powerful rocket, far surpassing the existing LVM3.

Design and Capabilities

The LMLV is a three-stage rocket:

• First two stages: Liquid propulsion.
• Third stage: Advanced cryogenic engine.

Its first stage alone will use 27 engines across a core and two strap-on boosters. The rocket is expected to be as tall as a 40-storey building, with individual strap-ons taller than the current LVM3.

Originally conceptualised from the Next Generation Launch Vehicle (NGLV) project, the LMLV will consolidate NGLV features and replace it entirely.

Strategic and Scientific Significance:

The LMLV enables crewed lunar landings, carrying heavy, human-rated spacecraft with life-support systems. It is also crucial for future deep space exploration beyond the Moon. The project will advance India's cryogenic, human-rating, and high-thrust propulsion technologies, placing ISRO among elite spacefaring nations.

Evolution of Indian Launch Vehicles:

1.       SLV-3 (1980) – India’s first indigenously developed rocket, led by Dr A.P.J. Abdul Kalam. Successfully launched Rohini satellite, placing India among space-faring nations.

2.      PSLV (1994) – The workhorse of ISRO, launched Chandrayaan-1 and Mangalyaan. Noted for its high reliability and versatility in launching satellites to different orbits.

3.      GSLV and GSLV Mk-III (LVM-3) – Enabled launches to Geostationary Transfer Orbit (GTO) and carried heavier payloads, including Chandrayaan-2 and Chandrayaan-3.

4.     LMLV (Upcoming) – Marks the transition to super heavy-lift capability, enabling ISRO’s foray into long-duration crewed missions and lunar logistics.

Challenges Ahead:

• Technological Complexity: Developing a vehicle of this scale requires advanced propulsion systems, thermal shielding, and navigation technologies.
• Human-Rating Certification: A significant milestone for manned missions, ensuring safety, redundancy, and fail-safe systems.
• Budget and Time Constraints: A long gestation period (10+ years) and sustained funding will be essential.
• Global Competition: SpaceX’s Starship, NASA’s SLS, and China’s Long March 9 are progressing fast in this domain.

 Conclusion:

The LMLV is not just a technological marvel, but a symbol of India's scientific ambition, strategic foresight, and commitment to Atmanirbhar Bharat in space technology. As ISRO sets its sights on the Moon and beyond, the LMLV will be a key enabler in ensuring that India becomes a leading space power in the 21st century.
