In a defining moment for India’s space program, the Indian Space Research Organisation (ISRO) is set to launch its heaviest-ever communication satellite, CMS-03, onboard the LVM3-M5 ‘Bahubali’ rocket today at 5:26 PM (November 2, 2025). The 4,410 kg multi-band satellite will be placed in a Geosynchronous Transfer Orbit (GTO) from the Satish Dhawan Space Centre, Sriharikota.
This mission signifies India’s ability to independently launch heavy payloads, a feat previously dependent on foreign launchers, marking a new chapter in India’s journey towards complete space self-reliance.
Key Takeaways about ISRO’s CMS-03 Satellite Launch
- Historic Milestone: First time ISRO is launching a satellite weighing over 4,000 kg from Indian soil.
- Rocket Used: LVM3-M5, also known as GSLV Mk III, nicknamed ‘Bahubali’ for its massive lifting power.
- Satellite Weight: 4,410 kg — the heaviest satellite launched from India.
- Orbit: Geosynchronous Transfer Orbit (GTO) at 29,970 km x 170 km.
- Launch Time: 5:26 PM IST, November 2, 2025.
- Purpose: To provide high-bandwidth and secure communication across India and nearby oceanic regions.
- Strategic Significance: Enhances defence communication through encrypted data relay for the Indian Armed Forces.
- Previous Dependence: Earlier heavy satellites like GSAT-11 and GSAT-20 were launched by Arianespace from French Guiana.
The ‘Bahubali’ Rocket: India’s Heavy-Lift Powerhouse
The LVM3-M5, officially termed GSLV Mk III, stands as India’s most powerful rocket. At 43.5 metres tall, it’s a three-stage launch vehicle built entirely with indigenous technology.
First Stage: Two massive S200 solid boosters developed at the Vikram Sarabhai Space Centre, Thiruvananthapuram, provide the lift-off thrust.
Second Stage: The L110 liquid propellant core, powered by twin Vikas engines, designed and developed at the Liquid Propulsion Systems Centre (LPSC).
Third Stage: The C25 cryogenic engine, the powerhouse of LVM3, enables heavy payload delivery to GTO.
This rocket can carry 4,000 kg to GTO and up to 8,000 kg to Low Earth Orbit (LEO), giving India the power to deploy advanced communication and scientific satellites from home soil.
A Mission That Redefines India’s Space Independence
This launch is not just about breaking weight records, it’s about breaking dependence. For decades, ISRO had to rely on foreign space agencies to launch its heaviest satellites. The success of CMS-03 aboard LVM3-M5 marks the moment when India truly demonstrates complete autonomy in heavy satellite launches.

It is a milestone that positions India among the few nations capable of sending large communication satellites into orbit without foreign assistance, saving both cost and time while strengthening national security.
Technical Excellence and Future Upgrades
ISRO’s engineers have designed LVM3 with future scalability in mind. Plans are underway to:
- Replace the C25 cryogenic stage with a more advanced C32 version, increasing thrust from 20 tonnes to 22 tonnes.
- Introduce a semi-cryogenic engine using kerosene and liquid oxygen, replacing the L110 liquid stage. This will boost payload capacity to 10,000 kg in Low Earth Orbit.
Such upgrades will make LVM3 one of the most powerful and efficient launch vehicles globally, capable of serving both civilian and strategic missions.
LVM3’s Proven Legacy of Success
LVM3 has an impeccable track record of reliability.
Its earlier missions include Chandrayaan-2 and the historic Chandrayaan-3, through which India became the first country to land near the Moon’s South Pole in 2023.
Its first developmental flight in 2014 tested the Crew Module Atmospheric Re-entry Experiment (CARE), laying the foundation for human spaceflight.
This mission, LVM3-M5, marks its fifth operational flight, further proving its consistency and dependability.
ISRO’s upcoming human-rated version (HRLV) of this rocket will power Gaganyaan, India’s first human spaceflight program, and support the future Bharatiya Antariksh Station; India’s own space station project.
CMS-03: India’s Strategic Communication Backbone
The CMS-03 satellite is a multi-band communication system designed to provide secure and high-speed connectivity across the Indian subcontinent and surrounding oceanic zones.
While ISRO has not officially confirmed defence applications, it is widely understood that CMS-03 will enable encrypted data transmission for the Indian Armed Forces, enhancing coordination between naval, air, and ground forces.
This not only ensures operational efficiency but also bolsters India’s strategic autonomy, especially in the era of information warfare and digital defence.
Strengthening India’s Position in the Global Space Arena
Through this mission, ISRO continues to solidify India’s position as a global leader in space technology. With seven successful LVM3 missions under its belt, India’s space agency now competes with elite international counterparts on both reliability and innovation.
The success of CMS-03 will open avenues for international collaborations, commercial launches, and the export of indigenous space technologies, furthering India’s dream of becoming a space superpower.
A Defining Leap Toward Space Self-Reliance
The CMS-03 mission is more than a technological achievement, it’s a symbol of India’s growing independence, confidence, and vision in space exploration. By mastering heavy-lift launch capabilities with its own LVM3 rocket, ISRO proves that India can reach new frontiers without external help.
From Chandrayaan’s triumphs to today’s landmark launch, this mission stands as a testament to Indian innovation, perseverance, and unity in science. As the countdown ticks toward liftoff, the world watches a nation that no longer looks to the stars, but now reaches them on its own.
From Space Exploration to Soul Realization: The Divine Knowledge of Tatvdarshi Sant Rampal Ji Maharaj Ji
While ISRO continues to make India proud with remarkable advancements like the launch of the CMS-03 communication satellite, it reminds us that human curiosity doesn’t stop at the boundaries of science. The journey beyond the stars is not only physical but also spiritual.
Tatvdarshi Sant Rampal Ji Maharaj Ji explains that just as scientists explore the mysteries of the universe, a true seeker should explore the mystery of the soul : Who am I? Where have I come from? What is the ultimate destination beyond this vast cosmos?
According to His divine knowledge, the secret of creation and the existence of all universes is already revealed in our holy scriptures. Through spiritual science, Sant Rampal Ji Maharaj Ji guides mankind toward that eternal world Satlok where complete peace, immortality, and true happiness exist, far beyond what any satellite can reach.
