It will be a proud moment for the whole nation. We want people to know about the quality and severity of perseverance ISRO space scientists have put into this ambitious space project.
You will learn many things about India’s moon mission in this post. We suggest you read this post till the end for this reason.
What Is Chandrayaan 3 Mission?
You need to know many things about it. This is one of those. ISRO has initiated this follow-on mission to Chandrayan-2. The objective is to demonstrate its safe landing and roving on the moon’s surface.
Lander and Rover’s configuration is one of its key specifications. It is about to be launched from Sriharikota. The potential of the following components will be leveraged to accomplish this task:
- LVM3 from SDSC SHAR.
- Propulsion module.
The power of this propulsion module will be utilized to carry the entire Lander and Rover configuration for 100 Kilometres inside the Lunar Orbit.
Let us now tell you some more important things about the mission and the spacecraft.
Chandrayaan 3 Launch Date
Chandrayaan-3 is set to launch in India on July 14 at 5:05 a.m. EDT from Sriharikota, India’s east coast.
All scientists and Indian nationals are waiting impatiently for its launch. The success of this mission will put India among the nations that landed the spacecraft softly at the moon’s surface.
Mission’s Total Cost
Mission’s total cost is around Rs2.5bn ($35m). This cost excludes the cost of the launch vehicle.
The launch vehicle is expected to cost Rs3.5bn ($50m) extra.
All in all, this entire mission could cost more than INR 6 billion ($85 million).
Name of the Chandrayaan 3 Launch Vehicle
ISRO has decided to use GSLV Mark 3 (GSLV Mk III) as the launch vehicle for the spacecraft. This three-stage heavy launch vehicle was used to launch Chandrayaan 2 in 2019.
A core liquid booster (L110), two solid rocket boosters (S200) on both sides and a cryogenic upper stage (C25), two Vikas engines are the specifications of a GSLV Mark 3 (GSLV Mk III) launch vehicle.
India’s biggest cryogenic engine CE-20 has been installed in it to power its upper stage. Both Vikas engines installed in it burn 110t of fuel to power its core stage.
The Lander Embedded In Chandrayaan 3
A passive Laser Retroreflector Array (Lander) has been embedded in this spacecraft to study the moon’s lunar laser ranges.
The team has persevered to ensure accurate extraction of the moon’s facts. In-situ experiments have already been initiated to run the mission smoothly.
Objectives of India’s Moon Mission
ISRO and the central government of India determined a couple of important lunar missions. A team of experienced space specialists has been prepared for it. The team is dedicating its wealth of experiences, resources, and time to accomplish those missions. Given below is the list of missions for your reference:
- Demonstration of Safe and Soft Landing on Moon’s Surface.
- Demonstrate the Rover roving on the Lunar Surface.
- To carry out all important in-situ scientific experiments.
How is ISRO Going To Achieve These Objectives?
We have found the answer to this million-dollar question for you. ISRO has equipped the Lander with several advanced technologies for it. Take a look at the list of technologies incorporated in the Lander:
- Altimeters: Altimeters are based on Laser & RF.
- Velocimeters: LDV (Laser Doppler Velocimeter Camera), and LHVC (Lander Horizontal Velocity Camera) are also part of it.
- Inertial Measurement: Laser Gyro-based IRAAP (Inertial Referencing And Accelerometer Package) has also been incorporated into it.

3.1. APXS (Alpha Particle X-ray Spectrometer).
3.2.LIBS (Laser-Induced Breakdown Spectroscopy)
An ILM (Indigenous Lander module), PM (Propulsion module), and a Rover
Part of ISRO Chandrayaan. These will help develop and demonstrate technological innovations needed for planetary missions.
Before deploying the Rover, the lander will first ensure its smooth landing on the Lunar surface. Hassle-free landing is important as the Rover will analyze in-situ chemicals of the lunar surface throughout its mobility.
This is the reason ISRO has equipped the Lander and Rover with special payloads. These payloads are required for experiments at the lunar surface.
What Will Be The Function of The Propulsion Module?
This question must have come to your mind at least once. Let us tell you something about it.
The Propulsion Module (PM) will carry the Lander Module (LM). It will carry LM from the LVI (Launch Vehicle Injection) till the last lunar 100 Kilometre Circular Polar Orbit. It will then separate the Lander Module from the Propulsion Module.
The Propulsion Module also has a scientific payload. This payload is like a value addition. It will be operated after the Lander Module gets separated.
What is more important is the launcher ISRO has identified for Chandrayaan 3 is GSLV MK3. It will be assigned the responsibility of placing the integrated module in an EPO (Elliptic Parking Orbit) of size ~170 x 36500 km.
How can we forget the Landing Leg Mechanism?
