LVM3-M4 — The Mission That Carried Chandrayaan-3 Toward the Moon
In the previous blog on LVM3-M3, we explored how India’s heavy-lift LVM3 rocket proved its reliability through repeated commercial satellite launches for the OneWeb mission. Those successful launches showed that India had developed not only a powerful rocket but also a dependable launch system trusted internationally.
The next major chapter came with LVM3-M4, one of the most important missions in India’s recent space history. Launched by Indian Space Research Organisation on 14 July 2023 from the Satish Dhawan Space Centre in Sriharikota, this mission carried the Chandrayaan-3 spacecraft toward the Moon. Unlike the commercial missions before it, LVM3-M4 returned India’s attention to lunar exploration and scientific research.
This mission attracted global attention because Chandrayaan-3 aimed to achieve what Chandrayaan-2 could not fully complete — a successful soft landing on the lunar surface. The launch of LVM3-M4 therefore became more than just another rocket flight. It represented India’s determination to improve, learn, and continue exploring space.
The Main Parts of LVM3
Although LVM3-M4 carried a different type of mission, the rocket itself used the same powerful three-stage design that has become central to India’s heavy launch capability.
S200 Solid Rocket Boosters
The rocket includes two giant S200 solid boosters attached on either side. These boosters ignite during liftoff and generate the huge amount of thrust needed to lift the heavy rocket into the sky.
They burn for the initial phase of flight before separating from the main vehicle.
L110 Liquid Core Stage
After the boosters separate, the L110 liquid stage takes over. This stage uses liquid propellants and operates with two Vikas engines.
The liquid stage helps the rocket maintain speed and stability as it continues climbing higher above Earth.
C25 Cryogenic Upper Stage
The final stage is the advanced C25 cryogenic stage, powered by the CE-20 engine. It uses super-cooled liquid hydrogen and liquid oxygen as fuel.
This stage is responsible for accurately placing spacecraft into their intended orbit or trajectory. In the Chandrayaan-3 mission, it helped place the spacecraft on its path toward the Moon.
Important Characteristics of LVM3
LVM3 has become India’s most powerful operational launch vehicle because of its size and lifting capacity.
Some key features include:
- Height of around 43 meters
- Liftoff weight close to 640 tonnes
- Capability to carry heavy payloads
- Ability to support deep-space missions
- Suitable for future astronaut missions under Gaganyaan
One reason LVM3 is important is that it gives India the ability to launch major missions independently without depending on foreign rockets.
What Is LVM3 Used For?
Over time, the role of LVM3 has expanded into several areas of space activity.
Scientific Missions
LVM3 is capable of launching spacecraft for lunar and planetary exploration missions, including Chandrayaan missions.
Communication Satellites
The rocket can place heavy communication satellites into orbit for television broadcasting, internet services, and weather monitoring.
Commercial Launches
Missions like LVM3-M2 and M3 demonstrated India’s growing role in the commercial satellite launch market.
Human Spaceflight
Future versions of LVM3 are expected to support the Gaganyaan mission, which aims to send Indian astronauts into space.
LVM3-M4 and the Chandrayaan-3 Mission
The most practical and historic use of LVM3-M4 was launching the Chandrayaan-3 mission.
The spacecraft included:
- A propulsion module
- Vikram lander
- Pragyan rover
After launch, the rocket successfully placed the spacecraft into Earth orbit. From there, Chandrayaan-3 gradually moved toward the Moon using a series of orbital maneuvers.
The mission later became historic when India successfully achieved a soft landing near the Moon’s south polar region. This made India one of the few countries to successfully land on the Moon and the first to land near the lunar south pole.
The success of Chandrayaan-3 also proved the reliability of LVM3 for deep-space missions. Launching a lunar spacecraft requires extremely precise timing, navigation, and orbital insertion. Even small errors can affect the mission. LVM3-M4 performed its role accurately, helping the spacecraft begin its successful journey.
Looking Ahead to LVM3-M5
LVM3-M4 became one of the most memorable missions in India’s modern space journey. It showed how years of learning, testing, and improving had transformed LVM3 into a trusted heavy-lift rocket capable of supporting major scientific achievements.
But every successful mission naturally leads to new curiosity. After Chandrayaan-3, people began wondering what would come next for LVM3. Would LVM3-M5 carry another lunar mission, a major satellite launch, or perhaps support preparations for India’s first astronaut mission?
That question keeps the excitement of space exploration alive, because in space science, every mission is both an achievement and the beginning of another journey.
