Introduction

In 2023, India achieved a significant milestone in space exploration with its third moon mission, Chandrayaan 3. This mission marked a remarkable success as it executed a soft landing on the lunar south pole.

Main Tasks of Chandrayaan 3 Which Could Not Be Achieved in Earlier Mission

1. Successful Soft Landing

   - Chandrayaan 3's primary goal to achieve soft landing on the Moon's surface, which was successfully made on 23 September 2023.

   - Chandrayaan 2's Vikram lander had failed in this aspect in 2019.

2. South Pole Exploration

   - Chandrayaan 3 has targeted the lunar south pole, which is of interest due to the presence of water ice in shadowed craters.

3. Pragyan Rover Deployment

   - Chandrayaan 3 deployed Pragyan rover on the Moon.

   - The rover conducted surface exploration and collected scientific data on the presence of Helium, water, rare earth minerals etc.

4. Technology Validation

   - The mission aimed to validate and improve lunar mission technologies.

   - This would benefit future lunar and space exploration missions.

 

Countries that have achieved successful soft landings on the Moon:

1. United States (Apollo missions)

2. Soviet Union (Luna missions)

3. China (Chang'e missions)

4. India (Chandrayaan 3)

 

Subsystems in the spacecraft launched by India (Chandrayaan 3):

1. Orbiter: The orbiter is a spacecraft that orbits the Moon and performs remote sensing operations, capturing images and data from lunar surface.

2. Lander: The lander is designed to carry scientific instruments and equipment to the lunar surface for in-situ studies. It consists of lander Vikram and rover Pragyan.

3. Rover: The rover is a mobile vehicle designed to move across the lunar surface, conducting experiments and collecting data.

4. Communication Systems: Chandrayaan 3 includes communication systems to relay data between the spacecraft and mission control on Earth.

5. Navigation and Guidance Systems: These systems are essential for precise control of the spacecraft's trajectory and landing.

6. Power Systems: Use of solar power to make the Rover functional for 1 lunar day (14 earth days).

7. Scientific Instruments: These instruments are used for scientific research and exploration of the Moon's surface, composition, and environment.

 

Role of the 'Virtual Launch Control Centre' at the Vikram Sarabhai Space Centre:

1. Remote Monitoring: The Virtual Launch Control Centre allowed for real-time remote monitoring of all aspects of the launch from Sriharikota, including the spacecraft's status, rocket performance, and trajectory.

2. Data Analysis: It collected and analyzed data from various sensors and instruments on both the launch vehicle and the spacecraft, ensuring that all systems were functioning correctly.

3. Simulation and Testing: The center likely conducted simulations and testing scenarios to prepare for various contingencies and emergencies that could occur during launch.

4. Decision-Making: It played a crucial role in decision-making during critical phases of the launch, such as assessing weather conditions and making adjustments to the launch schedule if necessary.

5. Communication Hub: It served as a central hub for communication between the launch team, mission control, and other relevant stakeholders, ensuring seamless coordination during the launch.

6. Problem Resolution: In the event of any anomalies or technical issues, the Virtual Launch Control Centre would have been instrumental in diagnosing problems and formulating solutions to ensure a successful launch.

7. Overall Management: It provided oversight and management of the entire launch operation, ensuring that all components of the mission were integrated and synchronized for a successful soft landing on the Moon's south pole.

 

Conclusion

The Chandrayaan 3 mission not only showcased India's technological capabilities but also contributed significantly to lunar research, especially in confirming the presence of water ice. it stands as a testament to India's commitment to pushing the boundaries of space exploration for the benefit of humanity.
