Understanding Chandrayaan-3: The Journey of ISRO's LVM3-M4 Rocket

Chandrayaan-3, India's ambitious lunar exploration mission, embarked on its historic journey to the Moon in July 2023. This mission, a significant leap for India's space program, utilized the LVM3-M4 launch vehicle, a powerful three-stage expendable launch system developed by the Indian Space Research Organisation (ISRO). In this article, we will delve into the details of this remarkable launch vehicle and its role in the Chandrayaan-3 mission.

The LVM3-M4 Launch Vehicle

Rocket Name: LVM3-M4 Launch Vehicle Mark 3 - Mission 4

The LVM3-M4 is a three-stage rocket designed and manufactured by the Indian Space Research Organisation (ISRO). Blessed with the capability to deliver payloads into various orbits, the LVM3-M4 is a crucial component of India's aerospace endeavors. Here are the key details about this remarkable rocket:

Design and Purpose

The LVM3-M4 was specifically designed for the Chandrayaan-3 mission, as well as other potential lunar and planetary exploration missions. Its primary purpose is to place payloads into the required orbits for subsequent inter-planetary voyages, such as the journey to the Moon.

Rocket Dimensions

Height: 43.5 meters (142.7 feet)
Mass: 640 tonnes (1,411,000 pounds)

Rocket Stages

The LVM3-M4 rocket is a three-stage expendable launch vehicle:

First Stage

The first stage of the LVM3-M4 is powered by four Vikas liquid rocket engines, each generating 805 kN (181,000 lbf) of thrust. This powerful ignition phase is essential for achieving the necessary velocity to escape Earth's gravitational pull.

Second Stage

Following the first stage, the second stage is equipped with one Vikas engine and two Vikas Liquid Boost Strap-on (VLBS) engines. This stage contributes a combined thrust of 1,320 kN (297,000 lbf), enabling the rocket to accelerate further.

Third Stage

The third stage of the LVM3-M4 uses a single Cryogenic Upper Stage (CUS) engine. This engine is fueled by liquid hydrogen and liquid oxygen, delivering 187 kN (42,000 lbf) of thrust. It is responsible for achieving the final velocities needed to deliver Chandrayaan-3 into an Earth parking orbit, from where the spacecraft will commence its lunar journey.

Key Mission: Chandrayaan-3

On July 14, 2023, the LVM3-M4 successfully placed Chandrayaan-3 into an Earth parking orbit. From this orbit, Chandrayaan-3 began its journey to the Moon. This mission was a significant milestone for ISRO, marking the fourth flight of the LVM3 launch vehicle.
