ISRO’s Historic Launch: LVM3-M5 Takes Flight with CMS-03

The Indian Space Research Organisation (ISRO) has achieved yet another landmark in its journey toward space excellence. On Sunday, India’s heaviest rocket, Launch Vehicle Mark-3 (LVM3-M5), successfully lifted off from the Satish Dhawan Space Centre in Sriharikota, carrying the CMS-03 communication satellite into orbit.

This mission marks a significant step forward in enhancing India’s space-based communication infrastructure and reaffirms ISRO’s global standing as a reliable and innovative space power.

The Mission in Detail

The LVM3-M5 rocket flawlessly executed each stage of its flight. After liftoff, it successfully separated its two S200 solid boosters and payload fairing, transitioning into the L110 liquid core stage. Upon the shutdown of the L110 engine, the vehicle entered its final and most sophisticated phase — the C25 cryogenic stage, powered by liquid hydrogen and liquid oxygen.

Each step of the mission showcased ISRO’s precision engineering, cutting-edge propulsion technology, and mission excellence.

About the LVM3 Rocket – India’s “Monster Rocket”

Formerly known as the GSLV Mk III, the LVM3 is ISRO’s most powerful launch vehicle, designed to carry heavy payloads to higher orbits. It uses three types of engines –

• Solid (S200),
• Liquid (L110), and
• Cryogenic (C25).

This combination gives the rocket immense versatility and thrust. The LVM3 can carry up to 8,000 kg to Low Earth Orbit (LEO) and 4,000 kg to Geosynchronous Transfer Orbit (GTO) at around 36,000 km altitude.

ISRO’s LVM3 has maintained a 100% success record across all its missions so far. It has launched several prestigious payloads, including:

• Chandrayaan-2 (2019)
• Chandrayaan-3 (2023)
• GSAT-19, GSAT-29 communication satellites
• OneWeb commercial missions (2022)

Global Recognition and Strategic Role

During the Russia-Ukraine conflict in 2022, global satellite launches faced disruptions. ISRO’s LVM3 stepped up to fill that void, successfully launching 72 OneWeb satellites for the UK-based company in two separate missions.

This global success story not only demonstrated India’s reliability as a launch partner but also prompted ISRO to formally rename the rocket “Launch Vehicle Mark-3 (LVM3)”, marking its evolution from a domestic heavy launcher to an internationally recognized commercial workhorse.

Why CMS-03 Matters

The CMS-03 communication satellite is designed to enhance India’s telecommunications and broadcasting services, especially in remote and rural regions. Once operational, the satellite will strengthen India’s communication backbone by supporting:

• High-speed internet services
• Television broadcasting
• Mobile connectivity
• Disaster management communication links

With this satellite, ISRO aims to bridge India’s digital divide and provide seamless communication access across the country, aligning with the government’s Digital India initiative.

A Step Toward Self-Reliance in Space

This evening’s successful launch is not just a technical achievement but a powerful symbol of India’s self-reliance in space technology. From indigenous cryogenic engines to advanced satellite payloads, ISRO continues to demonstrate its capability to design, build, and deploy complex systems entirely in-house.

Such missions reinforce India’s vision of becoming a global leader in space-based communication services while also supporting defense, navigation, and scientific research needs.

Looking Ahead: ISRO’s Expanding Horizons

With the success of the LVM3-M5 mission, ISRO is preparing for several ambitious upcoming projects:

• Gaganyaan – India’s first human spaceflight program
• Aditya-L1 – Solar observation mission
• NISAR – Earth observation satellite in collaboration with NASA
• Chandrayaan-4 – Planned follow-up to the lunar success of Chandrayaan-3

These missions highlight India’s growing dominance in the global space ecosystem, combining scientific innovation, cost efficiency, and technological independence.

A Proud Moment for India

The successful launch of the LVM3-M5 with the CMS-03 satellite once again showcases ISRO’s unmatched expertise and India’s growing prominence in the field of space technology. It is a reminder that India’s space journey is not just about reaching new orbits but also about empowering millions on Earth through better connectivity and communication.

As ISRO continues to push boundaries, each mission becomes a beacon of national pride and global recognition.
