Know the LVM3-M6: Reliable Heavy Lift Champion-

The LVM3-M6 mission refers to the sixth operational flight of India’s heavy-lift launch vehicle, Launch Vehicle Mark-3 (LVM3), also known as the “Bahubali” rocket — a name that evokes strength, capability, and national pride. In the case of LVM3-M6, the rocket had a lift-off mass of about 640 tonnes and stood approximately 43.5 metres tall — a testament to ISRO’s engineering prowess. LVM3 itself is India’s most powerful indigenous launch vehicle. It has a three-stage configuration comprising:

• Two solid strap-on boosters (S200)
• A liquid core stage (L110)
• A cryogenic upper stage (C25): Provide the thrust and precision required to place heavy payloads into orbit.

• Lift-off Mass: 640 tonnes total, including propellants and 6,100 kg BlueBird Block-2 payload.
• Diameter: Core body 4 meters; payload fairing 5 meters (ogive shape, 10.75m height).
• Payload Capacity (this mission): 6,100 kg to initial GTO (35,786 km apogee, 250 km perigee), heaviest LEO-class satellite from India.
• S200 Boosters: 2 x solid motors, 204.2 tonnes HTPB propellant each, 26.22m length, primary liftoff thrust generators.
• L110 Core Stage: Liquid-fueled (UH25/N2O4), 115.9 tonnes propellant, twin High Thrust Vikas Engines (HTVE) at 58.5 bar.
• C25 Upper Stage: Cryogenic CE-20 engine (LOX/LH2), 28.5 tonnes propellant, 13.5m length, precise orbit insertion with restart capability.
• Liftoff Thrust: 11,898 kN from boosters and core, enabling a rapid ascent trajectory.

Expanding Commercial Horizons through BlueBird Block-2-

At 6,100 kg, BlueBird Block-2, an innovative direct-to-cell 4G/5G communications from LEO satellite created by US-based AST SpaceMobile, is India’s largest commercial payload. It was launched using an LVM3-M6.

Objectives:

• Provide 4G and 5G connectivity straight to regular smartphones without the need for ground infrastructure, focusing on underserved and remote areas of the world.
• Bridge the digital divide across Asia-Pacific and beyond to enable mobile connectivity from space, telemedicine, and disaster alerts.
• Participate in the LEO constellation of AST SpaceMobile to enable smooth space-based cellular networks.

Features:

• Massive Phased Array Antenna: For broad coverage and fast data, this 2,400 square foot deployable array is the biggest commercial LEO antenna.
• Orbit Profile: For accurate station-keeping, it was sent to Low Earth Orbit (initial GTO: 35,786 km apogee, 250 km perigee).
• Technology: Enables interference-resistant signals for worldwide roaming, multi-beam steering, and direct-to-device 5G.
• It supports voice calls, video calls, text messaging and internet data services with 24×7 continuous coverage.

Significance of the Mission-

• Record-Breaking Payload Performance: The Indian mission marked a new record in the country’s space achievements, as the heaviest spacecraft ever launched by an Indian launcher was placed into orbit. The weight of 6,100 kg of the BlueBird Block-2 satellite, which dwarfed all previous missions, sets up a fresh benchmark to determine the potential of LVM3 launchers.
• Improved Business Credentials: Unlike other space missions, LVM3-M6 was a commercial mission taking place under an agreement between NewSpace India Limited (NSIL), the commercial arm of ISRO, and AST SpaceMobile. This goes to show that India can be a reliable partner for other countries in the competitive world of commercial space launches.
• Strategic Leap in Connectivity: The BlueBird Block-2 mission puts India and the international community at the cutting edge of efforts to close the digital divide. The mission of the satellite to provide direct mobile global broadband connectivity underlines the role that space technologies can play in the development of society, especially in underdeveloped and distant regions.
• Dominance in Heavy-Lift Launches: The LVM3 has successfully launched several major Indian missions, such as Chandrayaan-2, Chandrayaan-3, and OneWeb Commercial Launches. The successful launch of the LVM3-M6 mission further accentuates the continued excellence demonstrated by ISRO while handling heavy launchers.
